JUnit test — analysing expected Exceptions [duplicate]

Answer 1

Use MethodRule as a common solution, if you have many test cases to test

public class ExceptionRule implements MethodRule {
    @Override
    public Statement apply(final Statement base, final FrameworkMethod method, Object target) {
        return new Statement() {
            @Override
            public void evaluate() throws Throwable {
                try {
                    base.evaluate();
                    Assert.fail();
                } catch (CriticalServerException e) {
                    //Analyze the exception here
                }
            }
        };    
    }
}

Then use the Rule to your test class:

@Rule public ExceptionRule rule = new ExceptionRule();
