    ''''Initialize testing framework.
    A test file can provide many tests.  Each test starts with a
    declaration.  This declaration is a single line starting with \'#:\'.
    It declares codes of expected failures, separated by spaces or \'Okay\'
    if no failure is expected.
    If the file does not contain such declaration, it should pass all
    tests.  If the declaration is empty, following lines are not checked,
    until next declaration.
    Examples:
    * Only E224 and W701 are expected:         #: E224 W701
    * Following example is conform:            #: Okay
    * Don\'t check these lines:                 #:'
