如果您只想输出一些调试值,那么print
结合-s
参数的调用就足够了:
def test_spam():
print('debug')
assert True
运行pytest -s
:
collected 1 item
test_spam.py debug
.
如果您正在寻找更好地集成到pytest
执行流程中的解决方案,请编写自定义挂钩。下面的例子应该给你一些想法。
每次测试执行后打印自定义行
# conftest.py
def pytest_report_teststatus(report, config):
if report.when == 'teardown': # you may e.g. also check the outcome here to filter passed or failed tests only
rate = getattr(config, '_rate', None)
if rate is not None:
terminalreporter = config.pluginmanager.get_plugin('terminalreporter')
terminalreporter.ensure_newline()
terminalreporter.write_line(f'test {report.nodeid}, rate: {rate}', red=True, bold=True)
测试:
def report(rate, request):
request.config._rate = rate
def test_spam(request):
report(123, request)
def test_eggs(request):
report(456, request)
输出:
collected 2 items
test_spam.py .
test test_spam.py::test_spam, rate: 123
test_spam.py .
test test_spam.py::test_eggs, rate: 456
===================================================== 2 passed in 0.01 seconds =====================================================
测试执行后收集数据并打印
# conftest.py
def pytest_configure(config):
config._rates = dict()
def pytest_terminal_summary(terminalreporter, exitstatus, config):
terminalreporter.ensure_newline()
for testid, rate in config._rates.items():
terminalreporter.write_line(f'test {testid}, rate: {rate}', yellow=True, bold=True)
测试:
def report(rate, request):
request.config._rates[request.node.nodeid] = rate
def test_spam(request):
report(123, request)
def test_eggs(request):
report(456, request)
输出:
collected 2 items
test_spam.py ..
test test_spam.py::test_spam, rate: 123
test test_spam.py::test_eggs, rate: 456
===================================================== 2 passed in 0.01 seconds =====================================================
在 JUnit XML 报告中附加数据
使用record_property
夹具:
def test_spam(record_property):
record_property('rate', 123)
def test_eggs(record_property):
record_property('rate', 456)
结果报告:
$ pytest --junit-xml=report.xml
...
$ xmllint --format report.xml
