fra*_*ans 2 python performance report kpi pytest
我知道有用于性能测试和 py.test 分析的插件,但是有没有办法生成在测试后报告或以某种方式访问的任意值?
想象一下我有一个这样的测试
def test_minimum_learning_rate():
"""Make some fancy stuff and generate a learning performance value"""
learning_rate = fancy_learning_function().rate
pytest.report("rate", learning_rate)
assert learning_rate > 0.5

这pytest.report(..)条线就是我想要的(但不存在,不是吗?)
现在我想要将minimum_learning_rate[rate]实际测试结果与报告一起写入(或者至少在屏幕上)。
Jenkins 的一些插件真的很好,它可以根据这些数据创建一个漂亮的图表。
这有典型的措辞吗?我一直在寻找kpi,arbitrary values但user defined values还没有任何运气..
如果您只想输出一些调试值,则print与参数相结合的调用-s就足够了:
def test_spam():
print('debug')
assert True

跑步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。下面的例子应该会给你一些想法。
# 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)
