concurrencytest
Python testtools extension for running unittest suites concurrently.
Install from PyPI:
pip install concurrencytest
Requires:
- testtools :
pip install testtools
- python-subunit :
pip install python-subunit
Example:
import time
import unittest
from concurrencytest import ConcurrentTestSuite, fork_for_tests
class SampleTestCase(unittest.TestCase):
"""Dummy tests that sleep for demo."""
def test_me_1(self):
time.sleep(0.5)
def test_me_2(self):
time.sleep(0.5)
def test_me_3(self):
time.sleep(0.5)
def test_me_4(self):
time.sleep(0.5)
# Load tests from SampleTestCase defined above
suite = unittest.TestLoader().loadTestsFromTestCase(SampleTestCase)
runner = unittest.TextTestRunner()
# Run tests sequentially
runner.run(suite)
# Run same tests across 4 processes
suite = unittest.TestLoader().loadTestsFromTestCase(SampleTestCase)
concurrent_suite = ConcurrentTestSuite(suite, fork_for_tests(4))
runner.run(concurrent_suite)
Output:
