python - 像googletest一样制作pytest输出？

问题描述

我正在使用 PyTest 进行 python 代码测试。由于我使用 googletest 进行 C++ 代码测试，因此我喜欢 googletest 的输出格式。

我想知道，是否可以像 googletest 一样制作 pytest 输出？pytest 输出行太长，而 googletest 很短：

// pytest 示例：

解决方案

经过几个小时的搜索和尝试，我找到了conftest.py我需要的文件。在 conftest.py 中，人们可以覆盖默认的 pytest 函数，即通过提供钩子。

以下是 WIP 示例：

# conftest.py

import os
import random

def pytest_runtest_call(item):
    item.add_report_section("call", "custom", " [ Run      ]  " + str(item))

def pytest_report_teststatus(report, config):
    #print(">>> outcome:", report.outcome)

    if report.when == 'call':
        # line = f' [ Run      ]  {report.nodeid}'
        # report.sections.append(('ChrisZZ', line))
        if (report.outcome == 'failed'):
            line = f' [   FAILED ]  {report.nodeid}'
            report.sections.append(('failed due to', line))

    if report.when == 'teardown':
        if (report.outcome == 'passed'):
            line = f' [       OK ]  {report.nodeid}'
            report.sections.append(('ChrisZZ', line))

def pytest_terminal_summary(terminalreporter, exitstatus, config):
    reports = terminalreporter.getreports('')
    content = os.linesep.join(text for report in reports for secname, text in report.sections)
    if content:
        terminalreporter.ensure_newline()
        #terminalreporter.section('', sep=' ', green=True, bold=True)
        #terminalreporter.section('My custom section2', sep='------]', green=True, bold=True, fullwidth=None)
        terminalreporter.line(content)
