Static assert is used to make assertions at compile time. When the static assertion fails, the program simply doesn’t compile. This is useful in different situations, like, for example, if you implement some functionality by code that critically depends on unsigned int object having exactly 32 bits. You can put a static assert like this … Read more
Is my usage of assert as the left operand of the comma expression valid standard C? That is, does the standard allow me to use assert as an expression? Yes, it is valid as the left operand of the comma operator can be an expression of type void. And assert function has void as its … Read more
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

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
For “Visual Studio Team Test” it appears you apply the ExpectedException attribute to the test’s method. Sample from the documentation here: A Unit Testing Walkthrough with Visual Studio Team Test [TestMethod] [ExpectedException(typeof(ArgumentException), “A userId of null was inappropriately allowed.”)] public void NullUserIdInConstructor() { LogonInfo logonInfo = new LogonInfo(null, “P@ss0word”); }
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.
