What is TestInitialize?

(1) [TestInitialize] is used to run code before running each test, usually it is used to prepare aspects of the environment in which your unit test will run and to establish a known state for running your test.

What is ClassInitialize attribute in MS test?

The method decorated by [ClassInitialize] is called once before running the tests of the class. In some cases, you can write the code in the constructor of the class. The method decorated by [ClassCleanup] is called after all tests from all classes are executed.

Which attribute can be used to do the clean up work once all the tests are done?

For example, if you have any static or cached data or services, an action attribute can be used to clean them up for each test.

What is ClassInitialize?

ClassInitialize runs only on the initialization of the class where the attribute is declared. In other words it won’t run for every class. Just for the class that contains the ClassInitialize method. If you want a method that will run once before all tests or classes’ initialization use the AssemblyInitialize .

What is TestInitialize C#?

TestInitialize. This attribute is needed when we want to run a function before execution of a test. For example we want to run the same test 5 times and want to set some property value before running each time. In this scenario we can define one function and decorate the function with a TestInitialize attribute.

Does TestInitialize run for each test?

TestInitialize and TestCleanup are ran before and after each test, this is to ensure that no tests are coupled. If you want to run methods before and after ALL tests, decorate relevant methods with the ClassInitialize and ClassCleanup attributes.

What is TestContext Mstest?

Each NUnit test runs in an execution context, which includes information about the environment as well as the test itself. The TestContext class allows tests to access certain information about the execution context.

Is NUnit better than MsTest?

The main difference is the ability of MsTest to execute in parallel at the method level. Also, the tight integration of MsTest with Visual Studio provides advantages in both speed and robustness when compared to NUnit. As a result, I recommend MsTest.

What is AutoFixture?

AutoFixture is a tool designed to make Test-Driven Development more productive and unit tests more refactoring-safe.

Should I use AutoFixture?

You definitely can use it to test your units even when they have no dependencies, but in that case, you probably don’t need the AutoMoq Customization.

What is AutoFixture xUnit?

By leveraging the data theory feature of xUnit.net, this extension turns AutoFixture into a declarative framework for writing unit tests. In many ways it becomes a unit testing DSL (Domain Specific Language).

What is MSTest and VSTest?

Visual Studio includes the VSTest and MSTest command-line tools for testing purposes. We can use both VSTEST and MSTEST to run automated unit and coded UI tests from a command line. 1. VSTest. Console.exe is optimized for performance and is used in place of MSTest.exe in Visual Studio.

What is difference between NUnit and MSTest?

MsTest is a native unit testing library that comes with Visual Studio from Microsoft. NUnit is an extra Nuget package that needs to be installed on top and interact with the APIs of Visual Studio. Nunit likely doesn’t have direct integration into the native APIs like MsTest does.

Where is MSTest installed?

The default path is: C:\Program Files (x86)\Microsoft Visual Studio \Common7\IDE. Currently MSTest distributed with Microsoft Visual Studio/Visual Studio Test Agent 2015 is supported.

What is a fixture xUnit?

In xUnit, a test fixture is all the things we need to have in place in order to run a test and expect a particular outcome. Some people call this the test context.

What is AutoMoqCustomization?

The AutoMoqCustomization is the core of the integration of AutoFixture with Moq. By adding an instance of this class to the fixture, requests for non-concrete types will be handled by Moq.
