At present the tests run one after the other using a single CPU. This is not very efficient. Bring in the concurrencytest module and run the tests concurrently, using one process for each CPU by default. A -P option allows this to be overridden, which is necessary for code-coverage to function correctly. This requires fixing a few tests which are currently not fully independent. At some point we might consider doing this across all pytests in U-Boot. There is a pytest version that supports specifying the number of processes to use, but it did not work for me.

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:
