Project description

Build Status Downloads

Django Bench Runner is a drop-in enhancement of the default django test runner that times how long it takes to run individual tests. It helps detect tests that might need optimization.


pip install django-bench-runner

In, add:

TEST_RUNNER = 'django_bench_runner.runner.BenchRunner'


Add the -b (or --benchmark) flag when running your tests.


Tests that run under .5 seconds are colored green. The resulting tests are divvied into 3 groups. The fastest third (yellow), the middle third (magenta), and the slowest third (red). Red tests do not mean the tests are necessarily bad or in critical need of a speedup. It is just a graphical way to identify the various times of the tests.

Example Output

$ ./ test core.tests.test_transfer_money -b --keepdb
Using existing test database for alias 'default'...
