Unit testing expertise at your fingertips! 13:03:18 [xUnit] [INFO] - Stop build. So, to implement this first test, add the following method to the IntegrationTests class: Like you saw in the unit test example, the GetGlossaryList() method is decorated with the Fact attribute. assertion method calls in their tests should strongly consider including a You started to create unit tests to verify the behavior of an isolated and autonomous piece of code. It seems a trivial statement, but sometimes this statement is underrated, especially when you change your existing codebase. By including some unique text in each Assertion Message, we can make Test drivers who belong to the "single assertion per Test Method" school don't Finally, replace the implementation of the AddTermWithAuthorization test with the following: The only difference with the previous version of the test is how you get the access token. They take into account negative and positive cases and make sure that results are the ones you expected. The class fixture is a xUnit feature that allows you to share an object instance among all tests in a test class. They are also testing the integration with Auth0, which may be a good thing as an end-to-end test, but it could lead to some drawbacks. 2018-10-19T08:17:17Z tag:help.appveyor.com,2012-11-13:Comment/37237761 2015-06-28T17:22:51Z 2015-06-28T17:22:51Z XUnit is a testing framework that allows us to write tests on our production code. The best you can do in xUnit right now to emulate that is using Assert.True(false, "Message"), but this can cause confusion and noise in the test-output: message Expected: True Actual: False In the case of an explicit failure the only wanted output should be: message It would be nice if xUnit added an Assert.Fail(string message) operation which didn't include unnecessary assert-information, In practice, this package takes care of bootstrapping the project under test and allows you to change the application configuration for test purposes. From a syntax and semantics perspective, they are not so different from unit tests. You may worry about storing credentials in this configuration file. MSTest uses the string as the message to display if the exception is not thrown. If the test were to fail, the output would also be written to the console, such as to diagnose a failing test running in AppVeyor.. Let us go through important steps. added: This will now result in a useful failure message: Of course,this would be even more meaningful if the variables had Intent Revealing Names[SBPP]! I have over 20 years of experience as a software engineer and technical writer. the expression that was being evaluated (including the actual values) as While this is done automatically for an In a r… This column is the practical one: How to write tests with xUnit. Start testing the addition operation by ensuring that a request without an access token fails. Now, move to the integration-tests folder and type the following command in a terminal window: This command will clone the glossary GitHub repository in your machine. Usually, the number of tests decreases while passing from unit to end-to-end tests, following the well-known Test Pyramid diagram: Regarding the way to structure your automated tests, a typical approach follows the so-called AAA pattern. Make sure to be in the unit-tests folder and write the following commands in a terminal window: The first command creates the unit test project, while the second one adds to it a reference to the PasswordValidator project. This approach leads to a short and iterative development cycle based on writing a test and letting it fail, fixing it by writing the application code, and refactoring the application code for readability or performance. For the integration test I will use XUnit framework as the testing framework. Run your Nunit or Xunit test for Desktop .NET Framework or Mono using the Test Explorer UI. This application enables you to get terms definitions, create new ones, or update and delete the existing ones. So, add the new unit test implemented by the method NotValidPassoword() to the ValidityTest class, as shown below: In this case, you are passing an invalid password, and in the Assert step, you expect that the value returned by the IsValid() method is false. This helps in having a greater code coverage for your production code. It is a repetitive task, and w… Yes, we already have few ways to mock httpclient by writing a wrapper for HttpClient. If you run the tests with dotnet test you will get two successful tests. suppose we have some C# production code which is in our production project and we have some test classes in our TestProject for testing our production code. When the condition being asserted isn't true, outcome. message that at least distinguishes which assertion failed. expected "x" We can add all this After the command executes, you will find the unit-integration-test-xunit folder containing a unit-tests subfolder. The report file has been skipped. Recently, I wrote XUnit tests for a business object that requires catching exceptions generated by wrong property values in synchronous and asynchronous calls. The full code you are going to develop throughout the article is available in this GitHub repository. To create the integration test project, move to the integration-tests folder, and type the following command: As you already know, this command creates the basic xUnit test project in the Glossary.IntegrationTests folder. Then, follow the steps to configure the application, as explained in the article mentioned above. The PasswordValidator project is a very simple library to validate passwords with the following constraints: Its implementation is based on the following class defined in the PasswordValidator.cs file: As you can see, the validation logic is implemented by the IsValid() method through a regular expression. However, xUnit has become the most popular due to its simplicity, expressiveness, and extensibility. This endpoint responds to the api/glossary URL and returns a list of terms in JSON format. The endpoint to get term definitions is public, while the other endpoints are protected with Auth0 authentication and authorization features. In particular, it overrides the JwtBearerOptions configuration by assigning the values from the FakeJwtManager mock. Build inputs 4. may be less intuitive as it would require looking at the code to determine Set up data through the front door 3. As said, the addition, change, and deletion of terms are protected, and only authorized users can perform them. The book has now been published and the content of this chapter has likely changed substanstially. Manual testing is a very demanding task, not only for performing the tests themselves but because you have to execute them a huge number of times. the message. For example, while the unit tests are usually executed really fast, the end-to-end tests are slower and may have various points of failure due to the interaction of multiple systems. To replace it, you need to build an entity that generates and provides support to validate tokens. You will need it later on. Also, you removed the auth0Settings private variable definition and the initialization of that variable in the constructor. If we wanted to ensure that our code simply throws the ArgumentOutOfRangeException given a negative input, we'd write our test … In other words, each InlineData attribute represents one invocation of the ValidatePassword() test. The two cases of password validity tested by the unit tests are far from exhaustive. To understand how to use xUnit to automate your tests, let's explore the basics by creating unit tests for an existing project. In fact, it created the HTTP client instance for all the tests. In this case, you are using the True() method, which is successful when its first argument is true. As usual, to run this test, type dotnet test in a terminal window. This method has two parameters: password and expectedResult. You can get full control by writing the handling code yourself: When we scaffolded the xUnit test project, SpeedConverter.Tests, included for us is an example unit test testing class called UnitTest1.cs. Throughout my career, I've used several languages and technologies for the projects I was involved in, ranging from C# to JavaScript, ASP.NET to Angular and React. You can leverage the Auth0 Authentication API SDK to create an Auth0 client and easily request the needed token. The sample application you are testing returns a predefined set of term definitions, so this simplifies the Assert step of the test. Instead of using the GetAccessToken() method, you now are invoking FakeJwtManager.GenerateJwtToken(). Assertion Failed. In the Arrange step, you create an instance of the PasswordValidator class and define a possible valid password. Testing the protected endpoints is somewhat more complicated. In fact, when you have one or more external system involved in the application you are testing, you should be aware at least of the following issues: If your goal is to test only the correctness of your source code, you should avoid involving external systems in your integration tests. xUnit.net is a free, open-source, community-focused unit testing tool for .NET.. A common situation using xUnit xUnit uses the Assert class to verify conditions during the process of running tests. In addition to enterprise software development, he has also designed and developed both Windows Phone and Windows Store apps. In the Act step, you invoke the IsValid() method with the previously defined password. In this case, we want to communicate first of all Every Assertion Method takes an optional string parameter that The Web API application is configured to use Auth0 for access control. Besides the InlineData attribute, xUnit provides you with other ways to define data for theories, like ClassData, where the data source is a class implementing the IEnumerable interface, and MemberData, where the data source is a property or a method. In our test below, we are asserting that a ValidationException is thrown and also that the validation message is as expected. xUnit One of the most popular frameworks to test code in the .NET ecosystem is xUnit. Actually, in this specific case, the Assert step has been performed by the class constructor. Features. You have to make sure not only that your changes work as intended, but also that the untouched code continues to do its expected job. As a first step, you are going to test the public endpoint that allows you to get the list of term definitions. Open a shell window. It is useful to take a moment as we write each In this post, I will explain the basics of xUnit and how to write unit tests with it. . Discover and enable the integrations you need to solve identity, , Building and Securing Web APIs with ASP.NET Core 3, code implemented throughout this article on GitHub, The password length must be at least eight characters and a maximum of twenty characters, The password must contain one or more uppercase characters, The password must contain one or more lowercase characters, The password must contain one or more numeric values, The password must contain one or more special characters in the list @#!$%, if there is an issue with the remote system or in the infrastructure that connects your application to the external system, your tests will fail with an exception, you may need to call the external system directly as part of your tests (as seen in the example above), increasing the number of dependencies required to run the test, access to the external system may affect the performance of your tests. Now you can simplify your integration tests by getting rid of the appsettings.json configuration file and the code to manage it. Also, the test server instance provides us with the ability to get a preconfigured HTTP client through the CreateClient() method. So, in this test, you simply call the API and analyze the response, ensuring that it is as expected. Having a solutionmakes it easier to manage both the class library and the unit test project.Inside the solution directory, create a PrimeService directory. Edit the IntegrationTests.cs file and apply the changes shown below: You removed a few unnecessary namespaces from the using section and replaced the reference to the WebApplicationFactory class with the CustomWebApplicationFactory class. In this section, you are going to take a look at how to exclude the Auth0 integration from the integration tests you wrote so far. So, if your system is an API, an E2E test is a test that verifies that the API is correct. The name comes from the initials of the three actions usually needed to perform a test: Throughout this article, you will use this pattern in writing your tests. PreserveNewest It seems a trivial statement, but sometimes this statement is underrated, especially when you change your existing codebase. Now, it's time to take a look at how you can implement integration tests with xUnit. A theory is a parametric unit test that allows you to represent a set of unit tests sharing the same structure. At this point, rename the PasswordValidator.Tests/UnitTest1.cs file into PasswordValidator.Tests/ValidityTests.cs and replace its content with the following: Here you see the ValidityTest class, which is hosting the unit tests for the IsValid() method of the PasswordValidator class. Line 07: Notice the attribute Theory. This approach should ensure significant confidence in the correct behavior of the IsValid() method. comments in the test code. Right click on the project and choose Manage NuGet Packages option. You can find the code implemented throughout this article on GitHub. For the IsValid() method, you have to verify a possible case where the password passed as an argument doesn't comply with the constraints. The test should be able to automatically detect if it passed or failed without any human interaction. Create a CustomWebApplicationFactory.cs file with the following code: This class inherits from the WebApplicationFactory class and overrides the ConfigureWebHost() method. When the testing framework creates an instance of the IntegrationTests class, it creates an instance of an HTTP server running the glossary project as well. With these changes, you will get all tests successful again, but now your code will be independent of the external system. They are just two simple examples of positive and negative cases, but, of course, the possible cases to test are many more. You can do this by adding the following method to the IntegrationTests class: Here, you create a request to add a term definition, send the HTTP POST request to the endpoint, and verify that the status code received from the server is 401 Unauthorized. This means that you want to test the integration of just the software components building up your application. The .NET Core platform supports different testing frameworks. The first step is to create a mock for the external system; in the Web API application you are testing, that is Auth0. In xUnit, the most basic test method is a public parameterless method decorated with the [Fact] attribute. You know that code replication is not a good practice. Take note of the value of the audience parameter. The argumentation for this is that the unit test will fail if an exception is thrown and is unhandled. So, to have an idea of what theories are, replace the content of the ValidityTests.cs file with the following: The code above shows one single method, ValidatePassword(), in place of the two methods implemented before. More details can be found on xUnit’s Github page. As you can see below, the logging output is available in the test results in Visual Studio. xUnit uses this helper to write log messages to the test output of each test execution. Creating unit tests and integration tests with xUnit for C# applications. NUnit asserts that the string matches the exception's message. Download from GitHub the project to test by typing the following command: This command will clone only the starting-point-unit-tests branch of the repository in your machine. You can get this result by creating a custom version of the WebApplicationFactory class. The statements in the body of the ValidPassword() method are organized to highlight the AAA pattern mentioned above. However, they are testing more than the Web API application code. So lets get started. The TestServer is created upon the specified class: Glossary.Startup in this example. Fortunately, xUnit can help you with this issue with theories. Click the name of that application and take note of the Domain, Client ID, and Client Secret parameters: Now create an appsettings.json file in the root folder of the test project (integration-tests/Glossary.IntegrationTests) with the following content: In this file, replace the placeholders with the respective values you've just got from the Auth0 Dashboard. the Assertion Message is output to the Test Runner's log in Note the differences between NUnit and MSTest when you use the ExpectedException attribute with the optional string argument. MSBuild has used the message field, though, and it seems wasteful to just that information away. 13:03:18 [xUnit] [INFO] - There are errors when processing test results. But the ones above represent the most common ones from the developer's point of view. I have set MaxParallel threads through assembly in AssemblyInfo.cs in my test project : [assembly: Xunit.CollectionBehaviorAttribute(MaxParallelThreads = 4)] I have installed xunit-2.0.0-beta4-build2738(Prerelease). Fixing this is a simple matter of adding one more parameter to each Assertion Method call. When a business object requires catching exceptions generated by wrong property values, XUnit tests aren't as easy to write. I'll assume you've already seen the previous post on how to use [ClassData] and [MemberData]attributes but just for context, this is what a typical theory test and data function might look like: The test function CanAdd(value1, value2, expected) has three int parameters, and is decorated with a [MemberData] attribute that tells xUnit to load the parameters for the theory test from the Dataproperty. If we're going to write some unit tests, it's easiest to have something we want to test. Actually, you don't need to change the application you are testing. Finally, you have what you need to test the authorized request to create a new glossary term definition. Please see page 370 of xUnit Test Patterns for the latest information. Another When a test fails, we know what has actually happened. "Differences between integration tests and E2E tests are somewhat a matter of interpretation.". When testing your system, you cannot pretend to be able to cover all possible use cases. .net core provides xUnit, NUnit and MSTest as the test libraries. The following example tests t… This emits a failure message something like "Assertion Failed". addition to whatever output the assertion method normally generates. Create a directory called unit-testing-using-dotnet-test to hold the solution.Inside this new directory, run dotnet new sln to create a new solution. Stated Outcome Assertions (see Assertion Method). and exactly what the symptoms were when it happened. Finally, you discovered how to mock external systems to get your integration tests more focused on your own code. If you want to know the details of the project implementation, you can check out the Building and Securing Web APIs with ASP.NET Core 3 article. You can accomplish this by adding the following test: The only difference compared with the AddTermWithoutAuthorization() test is that here you added a Bearer token with an invalid value to the HTTP POST request. In this case, the shared object is an instance of the WebApplicationFactory class provided by the Microsoft.AspNetCore.Mvc.Testing library. A well-crafted Assertion Message makes it very easy to determine which assertion failed In the password validation example, this means that you should identify a representative set of valid and invalid passwords. The big question is "what should have happened?" Finally, the Assert step verifies that the returned result is the expected one. As a negative case, you should also verify that an attempt to add a new term with an invalid access token fails as well. If you registered your Web API with a different name, you should find that name followed by (Test Application). You may notice that the code implementing the test is missing the Arrange step. It’s designed for the Jenkins (previously Hudson) continuous build system, but will probably work for anything else that understands an XUnit-formatted XML representation of test results.. Add this shell command to your builder be able to see what the values of 'a' and 'b' actually were. The integration tests you implemented so far work fine. After making sure that adding a new term to the glossary requires you to be authorized, you need to create a test to verify that an authorized request works correctly. Fortunately, Auth0 automatically generated a test client application for you when you registered the Web API. This class creates a TestServer instance; that is, an in-memory server responding to HTTP requests. For each password in these sets, you should apply one of the tests implemented above. This article explains how to mock the HttpClient using XUnit. So, to have a valid access token from Auth0, you should register your test project as a client application, and configure it with the appropriate parameters. Manual testing is a very demanding task, not only for performing the tests themselves but because you have to execute them a huge number of times. A unit test should not take a disproportionately long time to write compared to the code being tested. Page generated at Wed Feb 09 16:39:45 +1100 2011, Copyright © 2003-2008 Gerard Meszaros all rights reserved. The project is supported by the .NET Foundation, and it is part of the more recent versions of .NET Core. The first attribute marks the ValidatePassword() method as a theory. To find the related parameters, access the Auth0 Dashboard and move to the Applications section. Shows a Test Explorer in the Test view in VS Code's sidebar with all detected tests and suites and their state; Adds CodeLenses to your test … In the above I check if the message of the exception matches the string "Exception!". Testing ensures that your application is doing what it's meant to do. On the other hand, people who find themselves coding several or many In this case, you get a valid access token by calling the GetAccessToken() method. Equality Assertion (see Assertion Method), we need to provide it ourselves for any "Unit tests ensure that an isolated component of a software application works as expected.". These are the ones which will be used by the test case. Here is the same test with the Argument Describing Message practice is to use the name of the variable or attribute being asserted on as In particular, your IntegrationTests class implements the IClassFixture interface. Testing ensures that your application is doing what it's meant to do. Among the worst are Stated Outcome Assertions such as This plugin provides test results in the standard XUnit XML format. This is intentional: xunit/xunit#350. So, storing the client's credentials in the configuration file is ok. To make the configuration file available at runtime, add the following ItemGroup element in the Glossary.IntegrationTests.csproj file: Unfortunately, the official documentation is very poor on these advanced but useful features. At the end of this article, you learned how to create different types of automated tests using xUnit. As mentioned in my previous post I find it odd that there is no DoesNotThrow method on Assert. Recently I'm mainly focusing on API design and on the JavaScript ecosystem where every day there's always something new to learn. So, you will find a glossary-web-api-aspnet-core subfolder with the new project within the integration-tests folder. Verify side effects One very simple example looks something like: We're trying to test "editing", but we're doing it through the commands actually used by the application. You have to make sure not only that your changes work as intended, but also that the untouched code continues to do its expected job. the test result log. which assertion was failing. Of course, each type of test brings value to ensuring the correctness of the software application, and each one has its strengths and weaknesses. Let's take a quick look at the definitions of the most common ones: Many other test definitions exist based on the test goals and the perspective with which you look at them. Powered by the Auth0 Community. Before we get into reviewing some different options, let me introduce the the libraries and frameworks up for review and the criteria I will be looking at. There are two schools of thought on this subject. The class also provides the GenerateJwtToken() method that provides you with a token generated from that values. Here, you will find an application named Glossary (Test Application). We make tests self-checking (see Goals of Test Automation on page X) by get out of it. This article will drive you to write tests without promoting any specific approach to software development. feel they need to include Assertion Messages because there is only one assertion to fail xUnit is an open source testing framework for the .Net framework and was written by the inventor of NUnit v2. Fortunately, .NET Core provides you with some features that allow you to mock external systems and focus on testing just your application code. This method receives the Web Host builder of the application and uses the ConfigureTestServices() method to configure the TestServer. Saying we need an message for each assertion method call is easy but what This is very simple and requires very little thought. With over 15 years experience, Jason Roberts is a former 5-time Microsoft .NET MVP, freelance developer, writer, and Pluralsight course author.He has written multiple books and is an open source contributor. options would be to number the assertions; this would certainly be unique but For this purpose, add the FakeJwtManager.cs file to the integration-tests/Glossary.IntegrationTests folder with the following content: The FakeJwtManager class provides the basic data you need to configure a JWT-based authorization system. Add xUnit to Our Test Project. OAuth2 and OpenID Connect: The Professional Guide. If you find testing the code taking a large amount of time compared to writing the code, consider a design that is more testable. Pretty easy! A better solution is to include a description of It is a software development process that promotes the writing of tests before writing your application code. The PasswordValidator class represents here a unit of code because it is self-contained and focused on one specific goal. Not very useful, is it? Sign up now to join the discussion. However, since your test project is not intended to be public, the scenario you are setting up is a machine-to-machine one. Now, to load these configuration data in your test project, apply the following changes to the code of the integration tests: You add new references to a few namespaces marked with //new in the using section. This is especially important if the tests are frequently run using a Command Line Test Runner (see Test Runner). There are If your system is a mobile app using this API, the E2E tests are the tests of the features accessible from the app's UI. Some types of Assertion Methods provide less helpful The package returns an ILogger or ILogger that wraps around the ITestOutputHelper supplied by xUnit. It kindly already includes a test method, decorated with [Fact] , a method attribute that's part of the xUnit testing library. When these fail, all we know Instead of an ExpectedException attribute that is more typical, XUnit has an Assert.Throws assertion that makes it easier to manage the exception and message data right where you are performing the test actions.
