Subject [jira] Commented: (SCXML-91) Test case bugs
Date Wed, 26 Nov 2008 11:32:44 GMT


Sebb commented on SCXML-91:

1) OK

2) There is so much output generated that it is possible to overlook the serialisation errors.
Also, a lot of this output is expected; it's tedious scanning through all of it.

Perhaps a work-round would be to add a single test to check the serialisability of a known
problematic class and report that as a failure.

SCXMLTestHelper#testExecutorSerializability() should not ignore I/O errors.

3) OK, I discovered this myself later.

> Test cases are difficult to debug if they fail.
> This is because many test cases catch Exception, and don't report it fully.
> Test cases should only catch a (specific) Exception if the test is expected to generate
one, and should otherwise throw the Exception.
> Several test cases report problems to System.out or System.err and carry on processing.
> For example, serialisation errors are largely ignored, and SCXMLTestHelper#testExecutorSerializability()
ignores IO errors.
> Testing generates a lot of output, some of which appears to be errors (e.g. stack traces)
yet the test passes.
> Ideally tests should suppress output stack traces which are expected during testing.
