(Mocha has a 'bail' config flag that's supposed to do this, but it doesn't seem
to work when passed to mocha.setup() (maybe because we're setting a custom fail
handler?), so this just calls abort() on the runner manually.)
This is arbitrary, and we could increase it more or make it configurable via
the command line if Travis continue to time out, but this allows all tests to
complete for me in a VM.
Not crazy about this, but (at least on my system) it's an easy way to
avoid DB errors due to interrupted transaction or query errors after the
DB connection was cleaned up. (I can reproduce those pretty reliably
right now by running collectionTreeView tests alone.)
Also some support code that was useful here and will probably be
useful for other tests. This is a pretty complicated thing to test, but
it seems to work.
Implements the beginnings of unit testing infrastructure using
mocha/chai. The unit tests can be run locally using test/runtests.sh,
although this will need tweaks to run on Windows. They should also run
on commit using Travis-CI.
The unit tests themselves live in test/tests. The index.js file
specifies separate test sets, which can be run individually by calling
test/runtests.sh <testsets>. Right now there is only a single unit
test, but hopefully we'll have more soon...
