Public async Task WhenTakesMoreTime_ThenItFails() When the method exceeds the defined time it fails with a proper explanation: We can use attribute to specify a maximum time for a test case to succeed. In some cases, we need to verify that method works fast enough. Public void WhenHaveDescription_ThenItsEasierToGetWhatItTests() ItвЂ™s helpful when we run tests automatically and give the test framework additional information to display in the log message: If the intention of the test case is not clear, itвЂ™s possible to provide additional descriptions to clarify what exactly is tested inside the test case. Public void WhenHasAuthor_ThenCanAccessItInCode() To do that, we need to mark the test method with the attribute: Test framework canвЂ™t check git history and determine the author of a test. Later we can run tests relying on specific values provided by metadata attributes. In that case, we can use additional metadata attributes to add information to our unit tests. In a huge project, we can end up with a very large number of unit tests. The attributes as TearDown and, accordingly, OneTimeTearDown give us such ability.

Sometimes we have a strict restriction to use a single instance of an object between all test cases and using the OneTimeSetup method to create such an object is the best option.ДЄlso, we have replacements for the Setup attributes that we can use to execute code after the test case is finished. It depends on what kind of resources we are going to set up before test case execution. We have another attribute that runs just once before all test cases run. With the attribute, we can execute a method before each test case run, and we can create a Calculator class instance inside this method: private Calculator _calculator NUnit provides a convenient way to execute a piece of code before all test methods or before each test method run. Now, we face the problem of creating a calculator instance inside each test method. Public static IEnumerable SourceProvider() Public void WhenDivideTwoNumbers_ThenReturnDivisionOfTwoNumbersProvidedBySource(int a, int b, double expected) It accepts the name of the static method or property, which provides values for the test method: We can solve this by using the attribute. Providing a Source With the TestCaseSource Attribute The attribute allows only constant values for params, but we can find ourselves in a situation where we need to create a value on the fly. Public void WhenDivideTwoNumbers_ThenReturnDivisionOfTwoNumbers(int a, int b, double expected) The attribute allows us to provide params for the test method: We can define test method parameters by using the attribute. ItвЂ™s a good approach to run our test methods with different arguments, without copy-pasting our test methods. TopMenu -> Tests -> Run All Tests, with a shortcut Ctrl R + T, o r from the console вЂ“ navigate to the test project directory and run the command: We can run all tests in a solution using Visual Studio with a few simple steps: It tells the NUnit framework that it should run this method.

To mark a method as a test case, we need to add a Test attribute. Public void WhenDivideTwoNumbers_ThenReturnDivisionOfTwoNumbers() LetвЂ™s define a simple test case to verify that the Divide method works properly: Now when we have the test project ready, we can start covering the Calculator class with unit tests. To be able to integrate with visual studio properly, we should also add the NUnit adapter package and Microsoft test SDK: dotnet add package NUnit3TestAdapterДotnet add package First Test Case

LetвЂ™s run the command to install the NUnit package in the Test project: Now itвЂ™s time to add the required NuGet packages. Also, we are going to add the reference from the main project to the testing project. We should rely on the naming convention and name it NUnitProject.UnitTests. The next step would be to add a test project to the solution. ItвЂ™s enough for our purposes: public class Calculator We are going to create a NUnitProject project with a single Calculator class that has just one method, Divide. LetвЂ™s define the simplest business logic class that we are going to test in this article. Each class we cover with tests should have a test class in the test project named accordingly with Test suffix. We should keep the same structure that we have in our business project.
