如何在 py.test 运行结束时获取 TestReports 列表? [英] How to get a list of TestReports at the end of a py.test run?

问题描述

我想在所有测试结束时获得所有测试的列表(例如以 py.test TestReport 的形式).

我知道 pytest_runtest_makereport 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来在 py.test 应用程序终止之前处理整个测试列表.

有没有办法做到这一点?

解决方案

这里有一个可以帮助您的示例.文件结构:

/示例:__init__.py # 空文件/test_pack_1__init__.py # 空文件conftest.py # pytest 钩子test_my.py # 一些演示测试

test_my.py 中有 2 个测试:

def test_one():断言 1 == 1打印('1==1')def test_two():断言 1 == 2打印('1！=2')

conftest.py 示例:

导入pytest从 _pytest.runner 导入 TestReport从 _pytest.terminal 导入 [e-mail](hookwrapper=True)def pytest_terminal_summary(terminalreporter): # type: (TerminalReporter) ->发电机屈服# 你可以在这里做任何事情 - 我只是打印报告信息打印('*' * 8 + '这里自定义逻辑' + '*' * 8)for failed in terminalreporter.stats.get('failed', []): # type: TestReportprint('failed! node_id:%s, duration: %s, details: %s' % (failed.nodeid,失败.持续时间，str(failed.longrepr)))for pass in terminalreporter.stats.get('passed', []): # type: TestReportprint('passed! node_id:%s, duration: %s, details: %s' % (passed.nodeid,通过.duration,str(passed.longrepr)))

文档说 pytest_terminal_summary 有 exitstatus arg

在没有任何附加选项的情况下运行测试:py.test ./example.输出示例:

example/test_pack_1/test_my.py .F********此处自定义逻辑********失败的！node_id:test_pack_1/test_my.py::test_two，持续时间:0.000385999679565，细节:def test_two():>断言 1 == 2E 断言 1 == 2示例/test_pack_1/test_my.py:7: 断言错误通过！node_id:test_pack_1/test_my.py::test_one，持续时间:0.00019907951355，细节:无==================================== 失败 ====================================___________________________________ 测试_二 ___________________________________def test_two():>断言 1 == 2E 断言 1 == 2示例/test_pack_1/test_my.py:7: 断言错误====================== 1 次失败，1 次在 0.01 秒内通过 ======================

希望这会有所帮助.

注意！确保在运行测试之前删除 .pyc 文件

I want to get a list of all tests (e.g. in the form of a py.test TestReport) at the end of all tests.

I know that pytest_runtest_makereportdoes something similar, but only for a single test. But I want to implement a hook or something in conftest.py to process the whole list of tests before the py.test application terminates.

Is there a way to do this?

解决方案

Here an example which can help you. Structure of files:

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

There are 2 tests in test_my.py:

def test_one():
    assert 1 == 1
    print('1==1')


def test_two():
    assert 1 == 2
    print('1!=2')

Example of conftest.py:

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

Run tests without any additional options: py.test ./example. Example of output:

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 ======================

Hope this helps.

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