# smoke.py: run some mongo tests.
|
|
|
|
# Bugs, TODOs:
|
|
|
|
# 0 Some tests hard-code pathnames relative to the mongo repository,
|
|
# so the smoke.py 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 smoke.py 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 cleanbb.py to clear out the dbpath, but cleanbb.py kills
|
|
# off all mongods on a box, which means you can't run two smoke.py
|
|
# jobs on the same host at once. So something's gotta change.
