junit-rule

In JUnit test case, a field annotated by @Rule must be public. It breaks a common Java coding convention (all class member variables should not be public). Why does JUnit require this? Documentation for @Rule : https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/Rule.java The JUnit runner will need to access the field reflectively to run the rule. If the field was private the access would throw IllegalAccessException . Another option would have been to have the runner modify the access from private to public before running the rule. However that could cause problems in case

I am testing a method with an expected exception. I also need to verify that some cleanup code was called (on a mocked object) after the exception is thrown, but it looks like that verification is being ignored. Here is the code. I am using the Junit ExpectedException Rule to verify the expected exception. @Rule public ExpectedException expectedEx = ExpectedException.none(); @Test public void testExpectedException() { MockedObject mockObj = mock(MockedObj.class); MySubject subject = new MySubject(mockedObj); expectedEx.expect(MyException.class); expectedEx.expectMessage("My exception message."

I have a test suite where I am logging out of the system in @After and closing the browser in @AfterClass . I am trying to use @Rule to take failed test screenshot using Selenium for every test method. I checked manually that @Rule only runs before every @Before but I want to set it up after @Test and before @After . I couldn't find out simple solution. Any help will be appreciated. public class MorgatgeCalculatorTest { @Before public void before(){ System.out.println("I am before"); } @BeforeClass public static void beforeclass(){ System.out.println("I am beforeclass"); } @Test public void
