Would you recommend doing any grouping of test cases within @Test methods, or have one @Test method per test scenario? For example, let's suppose that there are different ways to set the context in an application. Is the following idea acceptable? @Test public void testContextSetting() { // Test default setting assert(...) // Test setting a context variable assert(...) ... } Or, would you rather suggest having it like this, having each method as atomic as possible: @Test public void textDefaultSetting() { // Test default setting assert(...) } @Test public void testSettingContextVar() { // Test

Does TestNG have something like @Rule ? I am thinking specifically about: @Rule public TemporaryFolder folder = ... Or even @Rule public MethodRule globalTimeout = new Timeout(20); I am aware that I can manually implement these things using setUp() and tearDown() equivalents, but these don't give me the convenience that I get using @Rule . Cedric Beust Rules are pretty easy to emulate, for example with super classes: public void Base { @BeforeMethod public void createTempDir() { ... } @AfterMethod public void deleteTempDir() { ... } } public void MyTest extends Base { @Test ... } If you extend

I'm trying to run my junit test (to verify that a properties file loads correctly) but I get ClassNotFoundException although the class is there and all required libraries are there too. Here it is the error I get : Class not found ConfigurationManagerTest java.lang.ClassNotFoundException: ConfigurationManagerTest at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass

In Maven projects, I have some existing tests relying on JUnit 4. I cannot migrate these tests in JUnit 5 for multiple reasons. Essentially, some tests depend on a library which uses JUnit 4 runner and code migration may take time. I would like all the same create new test classes with JUnit 5 that is now released and provides new interesting features. How to do that ? JUnit 5 provides a way out of the box . JUnit 5 = JUnit Platform + JUnit Jupiter + JUnit Vintage Each one is a distinct project and using all of them allows to compile and execute JUnit 4 and JUnit 5 tests in a same project.

Could someone describe in a few words what the main differences between JUnit 3 and 4 are? Paul Sanwald 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. 来源： https://stackoverflow.com/questions/6685730/the-differences-between-junit-3-and-junit-4

I'm running a simple JUnit test agains an application DAO. The problem is that I always get: javax.persistence.RollbackException: Transaction marked as rollbackOnly The JUnit test is: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:com/my/app/context.xml"} @TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = false) @Transactional public class PerformanceTest { @Test @Transactional(propagation= Propagation.REQUIRES_NEW) @Rollback(false) public void testMsisdnCreationPerformance() { // Create a JPA entity // Persist JPA

I have the following test case in eclipse, using JUnit 4 which is refusing to pass. What could be wrong? @Test(expected = IllegalArgumentException.class) public void testIAE() { throw new IllegalArgumentException(); } This exact testcase came about when trying to test my own code with the expected tag didn't work. I wanted to see if JUnit would pass the most basic test. It didn't. I've also tested with custom exceptions as expected without luck. Screenshot: The problem is that your AnnounceThreadTest extends TestCase. Because it extends TestCase, the JUnit Runner is treating it as a JUnit 3.8
