intermittent dartdoc_integration_test failures on coverage runs #2692
Description
There are enough false positives now I'm noticing I'm tempted to ignore test failures at head.
It looks like dartdoc_integration_test fails sometimes when running coverage on the bots. I am unable to reproduce the problem locally. It seems to occur the most often on the negative integration tests (tests where we expect there to be a ProcessException raised). Hard to tell without being able to reproduce, but regardless of the permutations of exception handling, sometimes one of the exceptions "escapes" resulting in a test failure.
