type Assertion = IO () Source #

When an assertion is evaluated, it will output a message if and only if the assertion fails.

Test cases are composed of a sequence of one or more assertions.

Arguments

:: (?loc :: CallStack) 
=> String

A message that is displayed with the assertion failure

-> Assertion

   if conditionIsMet
       then IO ()
       else assertFailure msg

performTestCase Source #

Arguments

-> IO Result
