Class and Description
ExpectedException The ExpectedException rule allows you to verify that your code throws a specific exception.
ExternalResource A base class for Rules (like TemporaryFolder) that set up an external resource before a test (a file, socket, server, database connection, etc.), and guarantee to tear it down afterward: public static class UsesExternalResource { Server myServer= new Server(); @Rule public ExternalResource resource= new ExternalResource() { @Override protected void before() throws Throwable { myServer.connect(); }; @Override protected void after() { myServer.disconnect(); }; }; @Test public void testFoo() { new Client().run(myServer); } }
MethodRule A MethodRule is an alteration in how a test method is run and reported.
RuleChain The RuleChain rule allows ordering of TestRules.
TestRule A TestRule is an alteration in how a test method, or set of test methods, is run and reported.
TestWatcher TestWatcher is a base class for Rules that take note of the testing action, without modifying it.
Timeout The Timeout Rule applies the same timeout to all test methods in a class: public static class HasGlobalLongTimeout { @Rule public Timeout globalTimeout= new Timeout(20); @Test public void run1() throws InterruptedException { Thread.sleep(100); } @Test public void infiniteLoop() { while (true) {} } } Each test is run in a new thread.
Timeout.Builder Builder for Timeout.
Verifier Verifier is a base class for Rules like ErrorCollector, which can turn otherwise passing test methods into failing tests if a verification check is failed public static class ErrorLogVerifier { private ErrorLog errorLog = new ErrorLog(); @Rule public Verifier verifier = new Verifier() { @Override public void verify() { assertTrue(errorLog.isEmpty()); } } @Test public void testThatMightWriteErrorLog() { // ... } }
