# run some mongo tests.
# Bugs, TODOs:
# 0 Some tests hard-code pathnames relative to the mongo repository,
# so the process and all its children must be run with the
# mongo repo as current working directory. That's kinda icky.
# 1 The tests that are implemented as standalone executables ("test",
# "perftest"), don't take arguments for the dbpath, but
# unconditionally use "/tmp/unittest".
# 2 mongod output gets intermingled with mongo output, and it's often
# hard to find error messages in the slop. Maybe have do
# some fancier wrangling of child process output?
# 3 Some test suites run their own mongods, and so don't need us to
# run any mongods around their execution. (It's harmless to do so,
# but adds noise in the output.)
# 4 Running a separate mongo shell for each js file is slower than
# loading js files into one mongo shell process. Maybe have runTest
# queue up all filenames ending in ".js" and run them in one mongo
# shell at the "end" of testing?
# 5 Right now small-oplog implies master/slave replication. Maybe
# running with replication should be an orthogonal concern. (And
# maybe test replica set replication, too.)
# 6 We use to clear out the dbpath, but kills
# off all mongods on a box, which means you can't run two
# jobs on the same host at once. So something's gotta change.
