Different teardown for each @Test in jUnit

Best way to automagically migrate tests from JUnit 3 to JUnit 4?

There's actually an alternative to the @Test(expected=Xyz.class) in JUnit 4.7 using Rule and ExpectedException

In your test case you declare an ExpectedException annotated with @Rule, and assign it a default value of ExpectedException.none(). Then in your test that expects an exception you replace the value with the actual expected value. The advantage of this is that without using the ugly try/catch method, you can further specify what the message within the exception was

@Rule public ExpectedException thrown= ExpectedException.none();

@Test
public void myTest() {
    thrown.expect( Exception.class );
    thrown.expectMessage("Init Gold must be >= 0");

    rodgers = new Pirate("Dread Pirate Rodgers" , -100);
}

Using this method, you might be able to test for the message in the generic exception to be something specific.

ADDITION Another advantage of using ExpectedException is that you can more precisely scope the exception within the context of the test case. If you are only using @Test(expected=Xyz.class) annotation on the test, then the Xyz exception can be thrown anywhere in the test code -- including any test setup or pre-asserts within the test method. This can lead to a false positive.

Using ExpectedException, you can defer specifying the thrown.expect(Xyz.class) until after any setup and pre-asserts, just prior to actually invoking the method under test. Thus, you more accurately scope the exception to be thrown by the actual method invocation rather than any of the test fixture itself.

JUnit 5 NOTE:

JUnit 5 JUnit Jupiter has removed @Test(expected=...), @Rule and ExpectedException altogether. They are replaced with the new assertThrows(), which requires the use of Java 8 and lambda syntax. ExpectedException is still available for use in JUnit 5 through JUnit Vintage. Also JUnit Jupiter will also continue to support JUnit 4 ExpectedException through use of the junit-jupiter-migrationsupport module, but only if you add an additional class-level annotation of @EnableRuleMigrationSupport.

Maven Tutorial for Selenium

While working on a project for test automation, you’d require all the Selenium dependencies associated with it. Usually these dependencies are downloaded and upgraded manually throughout the project lifecycle, but as the project gets bigger, managing dependencies can be quite challenging. This is why you need build automation tools such as Maven to handle them automatically.

JUnit Tutorial:

LambdaTest also has a detailed JUnit tutorial explaining its features, importance, advanced use cases, best practices, and more to help you get started with running your automation testing scripts.

JUnit Tutorial Chapters:

Here are the detailed JUnit testing chapters to help you get started:

  • Importance of Unit testing - Learn why Unit testing is essential during the development phase to identify bugs and errors.
  • Top Java Unit testing frameworks - Here are the upcoming JUnit automation testing frameworks that you can use in 2023 to boost your unit testing.
  • What is the JUnit framework
  • Why is JUnit testing important - Learn the importance and numerous benefits of using the JUnit testing framework.
  • Features of JUnit - Learn about the numerous features of JUnit and why developers prefer it.
  • JUnit 5 vs. JUnit 4: Differences - Here is a complete comparison between JUnit 5 and JUnit 4 testing frameworks.
  • Setting up the JUnit environment - Learn how to set up your JUnit testing environment.
  • Getting started with JUnit testing - After successfully setting up your JUnit environment, this chapter will help you get started with JUnit testing in no time.
  • Parallel testing with JUnit - Parallel Testing can be used to reduce test execution time and improve test efficiency. Learn how to perform parallel testing with JUnit.
  • Annotations in JUnit - When writing automation scripts with JUnit, we can use JUnit annotations to specify the type of methods in our test code. This helps us identify those methods when we run JUnit tests using Selenium WebDriver. Learn in detail what annotations are in JUnit.
  • Assertions in JUnit - Assertions are used to validate or test that the result of an action/functionality is the same as expected. Learn in detail what assertions are and how to use them while performing JUnit testing.
  • Parameterization in JUnit - Parameterized Test enables you to run the same automated test scripts with different variables. By collecting data on each method's test parameters, you can minimize time spent on writing tests. Learn how to use parameterization in JUnit.
  • Nested Tests In JUnit 5 - A nested class is a non-static class contained within another class in a hierarchical structure. It can share the state and setup of the outer class. Learn about nested annotations in JUnit 5 with examples.
  • Best practices for JUnit testing - Learn about the best practices, such as always testing key methods and classes, integrating JUnit tests with your build, and more to get the best possible results.
  • Advanced Use Cases for JUnit testing - Take a deep dive into the advanced use cases, such as how to run JUnit tests in Jupiter, how to use JUnit 5 Mockito for Unit testing, and more for JUnit testing.
