smoke.py lets you run a subsets of the tests in jstests/. When it is running tests, it starts up an instance of mongod, runs the tests, and then shuts it down again. You can run it while running other instances of MongoDB on the same machine: it uses ports in the 30000 range and its own data directories.
For the moment, smoke.py must be run from the top-level directory of a MongoDB source repository. This directory must contain at least the mongo and mongod binaries. To run certain tests, you’ll also need to build the tools and mongos. It’s a good idea to run scons . before running the tests.
To run smoke.py you’ll need a recent version of PyMongo.
To see the possible options, run:
$ python buildscripts/smoke.py --help Usage: smoke.py [OPTIONS] ARGS* Options: -h, --help show this help message and exit --mode=MODE If "files", ARGS are filenames; if "suite", ARGS are sets of tests (suite) --test-path=TEST_PATH Path to the test executables to run, currently only used for 'client' (none) --mongod=MONGOD_EXECUTABLE Path to mongod to run (/Users/mike/mongo/mongod) --port=MONGOD_PORT Port the mongod will bind to (32000) --mongo=SHELL_EXECUTABLE Path to mongo, for .js test files (/Users/mike/mongo/mongo) --continue-on-failure If supplied, continue testing even after a test fails --from-file=FILE Run tests/suites named in FILE, one test per line, '-' means stdin --smoke-db-prefix=SMOKE_DB_PREFIX Prefix to use for the mongods' dbpaths ('') --small-oplog Run tests with master/slave replication & use a small oplog
By default, smoke.py will run tests that create data in /data/db, which may interfere with other MongoDB instances you are running. To change the directory in which the smoke tests create databases, use --smoke-db-prefix=/some/other/path
To run specific tests, use the --mode=files option:
python buildscripts/smoke.py --mode=files jstests/find1.js
You can specify as many files as you want.
You can also run a suite of tests. Suites are predefined and include:
To run a suite, specify the suite’s name:
python buildscripts/smoke.py js
You can run a jstest directly from the shell, for example:
mongo --nodb jstests/replsets/replsetarb3.js
scons test ./test
Build the unit tests (in src/mongo/unittest/ by running:
$ scons build/unittests.txt /* build output */ Generating build/unittests.txt build/linux2/dd/durableDefaultOff/mongo/platform/atomic_word_test ... build/linux2/dd/durableDefaultOff/mongo/bson_template_evaluator_test build/linux2/dd/durableDefaultOff/mongo/balancer_policy_test scons: done building targets.
Then use the line above to run the binary generated:
On OS X, the C++ unit tests will not pass unless you increase the file descriptor limit. To temporally change this setting issue the following command:
ulimit -n 2048
You can persist this change with the following command:
launchctl limit maxfiles 2048 2048
See UNIX ulimit Settings for more information.
