问题描述
我正在编写一个 django 应用程序。我正在尝试覆盖范围的单元测试和 pytest。根据我运行测试的方式，我会得到不同的覆盖率报告。
相关代码
我在 settings_test.py 中有这个，pytest 的一个运行器：
class PytestTestRunner(UnManagedModelTestRunner):
def __init__(self,verbosity=1,failfast=False,keepdb=False,**kwargs):
self.verbosity = verbosity
self.failfast = failfast
self.keepdb = keepdb
def run_tests(self,test_labels):
"""Run pytest and return the exitcode.
It translates some of Django's test command option to pytest's.
"""
import pytest
argv = []
if self.verbosity == 0:
argv.append('--quiet')
if self.verbosity == 2:
argv.append('--verbose')
if self.verbosity == 3:
argv.append('-vv')
if self.failfast:
argv.append('--exitfirst')
if self.keepdb:
argv.append('--reuse-db')
argv.extend(test_labels)
return pytest.main(argv)
TEST_RUNNER = "settings_test.UnManagedModelTestRunner"
还有这个脚本来运行测试：
runner.py
USAGE = """
USAGE:
python runner.py (will run unittest suite)
python runner.py unittest (will run unittest suite)
python runner.py pytest (will run pytest suite + coverage)
"""
TEST_RUNNERS_MAP = {
'pytest': 'testapp.settings_test.PytestTestRunner',# pytest
'unittest': 'testapp.settings_test.UnManagedModelTestRunner',# unittest
}
if __name__ == "__main__":
os.environ['DJANGO_SETTINGS_MODULE'] = 'testapp.settings_test'
django.setup()
# Get argument to decide which test suite to run.
arguments = sys.argv[1:]
arg = arguments[0] if 0 < len(arguments) else "unittest"
runner = TEST_RUNNERS_MAP[arg]
TestRunner = get_runner(settings,test_runner_class=runner)
test_runner = TestRunner()
failures = test_runner.run_tests(["unit_tests"])
sys.exit(bool(failures))
测试运行
$ pytest
