Pet's GSoC project, looking for suggestions on where we need more tests

[Bertrand Delacretaz <bd...@apache.org>]

Hi,

Our summer of code student Petr is making good progress, see
SLING-4757 for example where he's helped improve the test coverage.

If people have suggestions about important modules that are in need of
more test coverage, let us know!

If there are no specific suggestions I'll suggest that Petr works on
the bundles/engine and bundles/servlets next, which are core
components.

The idea is to avoid touching the existing main code and only add or
modify tests, and also not touch the poms except for what's in the
test scope, so we're not expecting any code changes, and if the tests
expose bugs we'll create distinct issues for them.

I'd also like to take the opportunity to move tests from
launchpad/testing closer to the modules that they test, but that's
probably for a second phase.
