¿Qué es TestCase en JUnit?

What is TestCase in JUnit?

JUnit Classes Assert − Contains a set of assert methods. TestCase − Contains a test case that defines the fixture to run multiple tests. TestResult − Contains methods to collect the results of executing a test case.

Running the Tests

1. Choose Run > Set Main Project in the main menu and select the JUnit-Sample project.
2. Choose Run > Test Project (JUnit-Sample) from the main menu.
3. Choose Window > IDE Tools > Test Results to open the Test Results window.

Important NUnit Annotations

A couple of examples to understand the term ‘Test Fixture’ parallelly cascaded with a head start on JUnit 4 lifecycle annotations like @Before, @After, @BeforeClass, @AfterClass, and @Test….Thus, the sequence of execution per the annotation for every test method is:

• @Before.
• @Test.
• @After.

JUnit is a Java unit testing framework that’s one of the best test methods for regression testing. An open-source framework, it is used to write and run repeatable automated tests. As with anything else, the JUnit testing framework has evolved over time.

Parameterized tests allow developers to run the same test over and over again using different values. TestNG lets you pass parameters directly to your test methods in two different ways − With testng.xml. With Data Providers.

The test data is either as object array or Iterable of object. The data feeder method arguments() is a public static method that is annotated with @Parameters annotation.

The nunit-console.exe program is a text-based runner and can be used when you want to run all your tests and don’t need a red/yellow/green indication of success or failure. It is useful for automation of tests and integration into other systems. dll that is part of the NUnit distribution.

TestCaseAttribute may appear one or more times on a test method, which may also carry other attributes providing test data. The method may optionally be marked with the Test Attribute as well.

xUnit Test Framework As seen in the example shown below, the [SetUp] and [TearDown] attributes from the NUnit framework are not present. Instead, a constructor is used for initialization, and a Dispose method is used for de-initialization. xUnit creates a new instance of the test class for every test.

Ignore causes the test case to be ignored and specifies the reason. IgnoreReason causes this test case to be ignored and specifies the reason. IncludePlatform specifies a comma-delimited list of platforms on which the test should run. Reason specifies the reason for not running this test case.

NUnit is patterned after JUnit, but if you’re using Visual Studio 2008 then consider the built-in unit testing framework. Unit test runner: Various, but personally I like the one in ReSharper.
