The differences between JUnit 3 and JUnit 4 [closed]
Java 5 annotations for setup and teardown (@before and @after) instead of setUp() and tearDown(). don’t need to extend TestCase anymore. @Test annotation replaces testSomeMethod() naming convention. static imports for asserts. Junit theories, which allow you to separate data sets from the test itself.
Javadoc in JUnit test classes?
I use Javadoc in my testing a lot. But it only gets really useful when you add your own tag to your javadoc.

How do I use Mockito to mock a protected method?

PowerMock testing – set static field of class
Whitebox.setInternalState(Foo.class, b); Works as long as you set a non-null value, and if theres only one field with the class of B. If you can’t rely on that luxury, you have to provide the field-name and cast the null to the type you want to set. In that case you would need to write something … Read more

It actually does a whole lot more than that (covered in the Spring Reference Manual), but that’s the basic idea. Whereas, the MockitoJUnitRunner provides support for creating mocks and spies with Mockito. However, with JUnit 4, you can … Read more
Run parallel test task using gradle
The accepted answer above works but the Gradle documentation here suggests you use maxParallelForks = Runtime.runtime.availableProcessors().intdiv(2) ?: 1 I tried both and after testing both on a 2.3 GHz Intel Core i7 Mac Book Pro with 16GB RAM (4 cores with hyperthreading) test { maxParallelForks = Runtime.runtime.availableProcessors() } and test { maxParallelForks = Runtime.runtime.availableProcessors().intdiv(2) ?: … Read more
Spring Dependency Injection with TestNG
It works with TestNG as well. Your test class needs to extend one of the following classes: org.springframework.test.context.testng.AbstractTestNGSpringContextTests org.springframework.test.context.testng.AbstractTransactionalTestNGSpringContextTests
assert that a list is not empty in JUnit
You can simply use assertFalse(result.isEmpty()); Regarding your problem, it’s simply caused by the fact that you forgot to statically import the is() method from Hamcrest; import static org.hamcrest.CoreMatchers.is;
How to get Junit 4 to ignore a Base Test Class?
Use to @Ignore annotation. It also works on classes. See this one: @Ignore public class IgnoreMe { @Test public void test1() { … } @Test public void test2() { … } } Also, you can annotate a class containing test methods with @Ignore and none of the containing tests will be executed.
