How do I use TestCaseData NUnit?
How do I use TestCaseData NUnit?
Using TestCaseData from NUnit for better test name
- The number of arguments on the test must match the number of arguments specified in the TestCaseData.
- The type of arguments on the test must also match the type of arguments specified in the TestCaseData.
What is TestFixture NUnit?
The [TestFixture] attribute at the beginning indicates that this class is a test fixture so that NUnit can identify it as a runnable test class. SetUp method is run at the start of test fixture and TearDown method is run at the end, after running all the test cases in the test fixture.
What is yield return in C#?
You use a yield return statement to return each element one at a time. When a yield return statement is reached in the iterator method, expression is returned, and the current location in code is retained. Execution is restarted from that location the next time that the iterator function is called.
What is the use of TestFixture attribute?
This is the attribute that marks a class that contains tests and, optionally, setup or teardown methods. Most restrictions on a class that is used as a test fixture have now been eliminated.
What is SetUp attribute?
The SetUp attribute is inherited from any base class. Therefore, if a base class has defined a SetUp method, that method will be called before each test method in the derived class. You may define a SetUp method in the base class and another in the derived class.
What is the use of OneTimeSetUp attribute?
This attribute is to identify methods that are called once prior to executing any of the tests in a fixture. It may appear on methods of a TestFixture or a SetUpFixture. OneTimeSetUp methods may be either static or instance methods and you may define more than one of them in a fixture.
What are the different methods of Assert?
Here is a list of the assert methods:
- assertArrayEquals()
- assertEquals()
- assertTrue() + assertFalse()
- assertNull() + assertNotNull()
- assertSame() + assertNotSame()
- assertThat()
How to write unit tests using testcasesource?
Write unit tests for a method first, so we defined our logic (TDD approach). Implement the method, so the tests would pass. Apply TestCaseSource to minimize amount of code used for testing. Business logic – implement a method to sum two integers. Conditions:
What does attribute mean in testcasesource Docs?
The attribute additionally identifies the method as a test method. The data is kept separate from the test itself and may be used by multiple test methods. See Parameterized Tests for a general introduction to tests with arguments.
How to use testcasesource to reduce code duplication?
For your reference, the full code snippet is below. While implementing separate unit tests per test case works, however sometimes using TestCaseSource approach can reduce code duplication and let you focus more on coding the test rather than copying and pasting the same test just to slightly modify it. Hope you find this useful!
How to use testcasesource in business logic?
Apply TestCaseSource to minimize amount of code used for testing. Business logic – implement a method to sum two integers. Conditions: If total is less or equals to zero, return zero. If total is greater or equals 100, return 100. Otherwise, return sum of both integers.
