+ * failureException: determines which exception will be raised when
+ the instance's assertion methods fail; test methods raising this
+ exception will be deemed to have 'failed' rather than 'errored'.
+ * longMessage: determines whether long messages (including repr of
+ objects used in assert methods) will be printed on failure in *addition*
+ to any explicit message passed.
+ * maxDiff: sets the maximum length of a diff in failure messages
+ by assert methods using difflib. It is looked up as an instance
+ attribute so can be configured by individual tests if required.
