unittest.FunctionTestCase.addTypeEqualityFunc¶

FunctionTestCase.addTypeEqualityFunc(typeobj, function)¶

Add a type specific assertEqual style function to compare a type.

This method is for use by TestCase subclasses that need to register their own type equality functions to provide nicer error messages.

Args:

typeobj: The data type to call this function on when both values

are of the same type in assertEqual().

function: The callable taking two arguments and an optional

msg= argument that raises self.failureException with a useful error message when the two arguments are not equal.
