public Statement methodBlock(FrameworkMethod method)

Description copied from class: BlockJUnit4ClassRunner

Returns a Statement that, when executed, either returns normally if method passes, or throws an exception if method fails. Here is an outline of the default implementation:

• Invoke method on the result of createTest(), and throw any exceptions thrown by either operation.
• HOWEVER, if method's @Test annotation has the expecting attribute, return normally only if the previous step threw an exception of the correct type, and throw an exception otherwise.
• HOWEVER, if method's @Test annotation has the timeout attribute, throw an exception if the previous step takes more than the specified number of milliseconds.
• ALWAYS allow @Rule fields to modify the execution of the above steps. A Rule may prevent all execution of the above steps, or add additional behavior before and after, or modify thrown exceptions. For more information, see MethodRule
• ALWAYS run all non-overridden @Before methods on this class and superclasses before any of the previous steps; if any throws an Exception, stop execution and pass the exception on.
• ALWAYS run all non-overridden @After methods on this class and superclasses after any of the previous steps; all After methods are always executed: exceptions thrown by previous steps are combined, if necessary, with exceptions from After methods into a MultipleFailureException.

This can be overridden in subclasses, either by overriding this method, or the implementations creating each sub-statement.
