如何在pytest运行时获取测试名称和测试结果 [英] How to get test name and test result during run time in pytest

问题描述

我想在运行时获取测试名称和测试结果.

I want to get the test name and test result during runtime.

我的脚本中有 setup 和 tearDown 方法.在setup中需要获取测试名称，在tearDown中需要获取测试结果和测试执行时间.

I have setup and tearDown methods in my script. In setup, I need to get the test name, and in tearDown I need to get the test result and test execution time.

有没有办法做到这一点?

Is there a way I can do this?

推荐答案

你可以，使用钩子.

我的测试目录中有这些文件:

I have these files in my test directory:

./rest/
├── conftest.py
├── __init__.py
└── test_rest_author.py

在test_rest_author.py中我有三个函数，startup、teardown和test_tc15，但我只想要显示 test_tc15 的结果和名称.

In test_rest_author.py I have three functions, startup, teardown and test_tc15, but I only want to show the result and name for test_tc15.

创建一个 conftest.py 文件(如果您还没有)并添加:

Create a conftest.py file if you don't have one yet and add this:

import pytest
from _pytest.runner import runtestprotocol

def pytest_runtest_protocol(item, nextitem):
    reports = runtestprotocol(item, nextitem=nextitem)
    for report in reports:
        if report.when == 'call':
            print '\n%s --- %s' % (item.name, report.outcome)
    return True

钩子 pytest_runtest_protocol 为给定的测试项实现 runtest_setup/call/teardown 协议，包括捕获异常和调用报告钩子.它在任何测试完成时调用(例如 startup 或 teardown 或您的测试).

The hook pytest_runtest_protocol implements the runtest_setup/call/teardown protocol for the given test item, including capturing exceptions and calling reporting hooks. It is called when any test finishes (like startup or teardown or your test).

如果你运行你的脚本，你可以看到测试的结果和名称:

If you run your script you can see the result and name of the test:

$ py.test ./rest/test_rest_author.py
====== test session starts ======
/test_rest_author.py::TestREST::test_tc15 PASSED
test_tc15 --- passed
======== 1 passed in 1.47 seconds =======
