twisted.trial.unittest.SynchronousTestCase.flushWarnings : API documentation

Remove stored warnings from the list of captured warnings and return them.

Parameters	offendingFunctions	If `None`, all warnings issued during the currently running test will be flushed. Otherwise, only warnings which point to a function included in this list will be flushed. All warnings include a filename and source line number; if these parts of a warning point to a source line which is part of a function, then the warning points to that function. (type: `None` or `list` of functions or methods.)
Returns	A `list`, each element of which is a `dict` giving information about one warning which was flushed by this call. The keys of each `dict` are: `'message'`: The string which was passed as the message parameter to `warnings.warn`. `'category'`: The warning subclass which was passed as the category parameter to `warnings.warn`. `'filename'`: The name of the file containing the definition of the code object which was `stacklevel` frames above the call to `warnings.warn`, where `stacklevel` is the value of the `stacklevel` parameter passed to `warnings.warn`. `'lineno'`: The source line associated with the active instruction of the code object object which was `stacklevel` frames above the call to `warnings.warn`, where `stacklevel` is the value of the `stacklevel` parameter passed to `warnings.warn`.
Raises	ValueError	If `offendingFunctions` is not `None` and includes an object which is not a `types.FunctionType` or `types.MethodType` instance.
