[Piglit] [PATCH] framework: Handle tests with subtests crashing in totals

[Dylan Baker]

I mean to CC Fabien as well...

> Currently piglit doesn't account for a test with subtests crashing when
> it calculates the total number of tests of each status. The result is
> that if a test with subtests runs no tests before crashing it is handled
> correctly (since it goes down the non-subtest path), but if one or more
> subtests are run, and those tests return a better result than crash,
> then the test will be marked as that status instead.
> 
> The real problem is that the python framework has no idea how many
> subtests that a test binary is going to run, so if the test crashes it
> has no idea if some subtests weren't run. To paper over that if the
> result of a test is not the same as the worst result of it's subtests
> we'll treat the test as a single test rather than a group, this results
> in the summaries generating the expected results.
> 
> A better fix would be to have tests with subtests inform the framework
> (preferably via JSON) that all of the subtests that it will run before
> it starts running, so that the python framework can pre-populate the
> subtests and generate the right result.
> 
> This solution is a better in the short term because it makes the results
> consistent, if a test crashes or not it will produce the same results.
