java - How to create own annotation for junit that will skip test if concrete exception was thrown during execution?

Question

My application have several execution modes, and in 1 mode it is normal that some of my tests will throw a concrete exception. I need to annotate this methods with something like @SkipOnFail that will set method as skipped if exception was thrown.

thanks in advance!

@Edit(for my question to be more clear)

@Test(expected=ConcreteException.class)

does not work for me because i need my tests to pass even if ConcreteException.class was not thrown(expected tag in junit will mark my test as failed if this exception won't be thrown), and to be skipped otherwise. In all other cases it should work as always.

@Solution that worked for me(junit v4.7) thx to @axtavt

@Rule
public MethodRule skipRule = new MethodRule() {
    public Statement apply(final Statement base, FrameworkMethod method, Object target) {
        if(method.getAnnotation(SkipOnFail.class) == null) return base;

        return new Statement() {
            @Override
            public void evaluate() throws Throwable {
                try{
                    base.evaluate();
                } catch (ConcreteException e) {
                    Assume.assumeTrue(false);
                }
            }
        };
    }
};

@Thx

Answer 1

I don't think that such a feature is available out of the box, but it should be pretty easy to implement with custom TestRule and Assume, something like this:

@Rule
public TestRule skipRule = new TestRule() {
    public Statement apply(final Statement base, Description desc) {
         if (desc.getAnnotation(SkipOnFail.class) == null) return base;

         return new Statement() {
             public void evaluate() throws Throwable {
                 try {
                     base.evaluate();
                 } catch (MyExceptoion ex) {
                     Assume.assumeTrue(false);
                 }
             }
         };
    }
};
