- - ### Method Detail

    - #### public static Throwable shouldFail(Closure code)

      Asserts that the given code closure fails when it is evaluated

      Parameters:
        `code` - the code expected to throw the exception
      Returns:
        the message of the thrown Throwable

    - #### public static Throwable shouldFail(Class clazz, Closure code)

      Asserts that the given code closure fails when it is evaluated and that a particular exception is thrown.

      Parameters:
        `clazz` - the class of the expected exception
        `code` - the closure that should fail
      Returns:
        the message of the expected Throwable

    - #### public static Throwable shouldFailWithCause(Class clazz, Closure code)

      Asserts that the given code closure fails when it is evaluated and that a particular exception can be attributed to the cause. The expected exception class is compared recursively with any nested exceptions using getCause() until either a match is found or no more nested exceptions exist.

      If a match is found the error message associated with the matching exception is returned. If no match was found the method will fail.

      Parameters:
        `clazz` - the class of the expected exception
        `code` - the closure that should fail
      Returns:
        the message of the expected Throwable
