如何在py.test运行结束后获取TestReports列表？

Question

我想得到所有测试的列表（例如py.测试测试报告）在所有测试结束时。在

我知道pytest_runtest_makereport也做了类似的事情，但只针对单个测试。但是我想在conftest.py中实现一个钩子或其他东西，以便在py.test应用程序终止之前处理整个测试列表。在

有办法吗？在

这里有一个可以帮助你的例子。文件结构：

/example:
   __init__.py  # empty file
   /test_pack_1
      __init__.py # empty file
      conftest.py # pytest hooks
      test_my.py  # a few tests for demonstration

在test_my.py中有2个测试：

^{pr2}$

conftest.py示例：

import pytest
from _pytest.runner import TestReport
from _pytest.terminal import TerminalReporter


@pytest.hookimpl(hookwrapper=True)
def pytest_terminal_summary(terminalreporter):  # type: (TerminalReporter) -> generator
    yield
    # you can do here anything - I just print report info
    print('*' * 8 + 'HERE CUSTOM LOGIC' + '*' * 8)

    for failed in terminalreporter.stats.get('failed', []):  # type: TestReport
        print('failed! node_id:%s, duration: %s, details: %s' % (failed.nodeid,
                                                                 failed.duration,
                                                                 str(failed.longrepr)))

    for passed in terminalreporter.stats.get('passed', []):  # type: TestReport
        print('passed! node_id:%s, duration: %s, details: %s' % (passed.nodeid,
                                                                 passed.duration,
                                                                 str(passed.longrepr)))

Documentation says that pytest_terminal_summary has exitstatus arg

不使用任何附加选项运行测试：py.test ./example。输出示例：

example/test_pack_1/test_my.py .F
********HERE CUSTOM LOGIC********
failed! node_id:test_pack_1/test_my.py::test_two, duration: 0.000385999679565, details: def test_two():
>       assert 1 == 2
E       assert 1 == 2

example/test_pack_1/test_my.py:7: AssertionError
passed! node_id:test_pack_1/test_my.py::test_one, duration: 0.00019907951355, details: None

=================================== FAILURES ===================================
___________________________________ test_two ___________________________________

    def test_two():
>       assert 1 == 2
E       assert 1 == 2

example/test_pack_1/test_my.py:7: AssertionError
====================== 1 failed, 1 passed in 0.01 seconds ======================

希望这有帮助。在

Note! Make sure that .pyc files was removed before running tests
