Bug 137281 – commitqueuetasks_unittest does not construct FailingTestCommitQueue objects properly in its test cases

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Jake Nielsen]

FailingTestCommitQueue expects to be constructed with a list of exceptions to throw, and a list of lists of tests to report as failed.
Presently, two tests instead pass a list of strings as the second argument, but since strings can still be indexed into, the bug was hidden.
Fix it.

Can we make FailingTestCommitQueue less error prone to use? One idea is to assert in FailingTestCommitQueue.test_results() that failures_for_run is an instance of a list object. Another idea is to convert failures_for_run to a list if it is an instance of a basestring (*). The latter approach would make FailingTestCommitQueue() work for a list-like data structure of strings as well as a list-like data structure of lists-like data structures and we wouldn't need to change tests test_double_flaky_test_failure() and test_red_test_failure().

(*) Note, basestring was removed In Python 3. Instead, we would need to convert failures_for_run to a list if it is an instance of str.
