inspect.ismethod is what you want to find out if you definitely have a method, rather than just something you can call. import inspect def foo(): pass class Test(object): def method(self): pass print inspect.ismethod(foo) # False print inspect.ismethod(Test) # False print inspect.ismethod(Test.method) # True print inspect.ismethod(Test().method) # True print callable(foo) # True print callable(Test) # True … Read more
The old method (of JUnit 3) was to mark the test-classes by extending junit.framework.TestCase. That inherited junit.framework.Assert itself and your test class gained the ability to call the assert methods this way. Since version 4 of JUnit, the framework uses Annotations for marking tests. So you no longer need to extend TestCase. But that means, … Read more
There is no standard assert in JavaScript itself. Perhaps you’re using some library that provides one; for instance, if you’re using Node.js, perhaps you’re using the assertion module. (Browsers and other environments that offer a console implementing the Console API provide console.assert.) The usual meaning of an assert function is to throw an error if … Read more
In JUnit4 the exception (actually Error) thrown by a JUnit assert is the same as the error thrown by the java assert keyword (AssertionError), so it is exactly the same as assertTrue and other than the stack trace you couldn’t tell the difference. That being said, asserts have to run with a special flag in … Read more
You must #define NDEBUG (or use the flag -DNDEBUG with g++) this will disable assert as long as it’s defined before the inclusion of the assert header file.
Sometimes I have exactly one assert per test case, but I think more often I have several assert statements. I’ve seen the case that @Arkain eludes to, where a very large piece of code has a single unit test suite with just a few test cases, and they are all labeled testCase1, testCase2, etc, and … Read more
You can use issubclass() like this assert issubclass(suit, Suit).
To be specific: Go to Run->run configuration select java application in left nav pan. right click and select New. select Arguments tab Add -ea in VM arguments.
Use assertions for internal logic checks within your code, and normal exceptions for error conditions outside your immediate code’s control. Don’t forget that assertions can be turned on and off – if you care about things like argument validation, that should be explicit using exceptions. (You could, however, choose to perform argument validation on private … Read more
In python 2 only (not python 3): assert not isinstance(lst, basestring) Is actually what you want, otherwise you’ll miss out on a lot of things which act like lists, but aren’t subclasses of list or tuple.
