避免打印点

Question

我使用选项-q运行pytest。

不幸的是，这会打印出许多点。示例：

...................................................................................s...............s...................................ssssss..................................................................................................................................s..............s.........................s..............................................................................................................F....s.s............s.....................s...........................................................................................................................
=================================== FAILURES ===================================
_____________________ TestFoo.test_bar _____________________
Traceback (most recent call last):
  (cut)

有办法避免这么长的点和“ s”字符吗？

更新

有一个有效的答案。但是不知何故对我来说太长了。我现在使用此解决方法：我将其添加到了调用pytest的脚本中：pytest -q | perl -pe 's/^[.sxFE]{20,}$//g'

Answer 1

详细信息选项无法关闭测试结果打印。但是，pytest可以通过多种方式进行自定义，包括结果打印。要更改此设置，您可以覆盖pytest_report_teststatus钩子。

关闭短字母

创建具有以下内容的文件conftest.py：

import pytest

def pytest_report_teststatus(report):
    category, short, verbose = '', '', ''
    if hasattr(report, 'wasxfail'):
        if report.skipped:
            category = 'xfailed'
            verbose = 'xfail'
        elif report.passed:
            category = 'xpassed'
            verbose = ('XPASS', {'yellow': True})
        return (category, short, verbose)
    elif report.when in ('setup', 'teardown'):
        if report.failed:
            category = 'error'
            verbose = 'ERROR'
        elif report.skipped:
            category = 'skipped'
            verbose = 'SKIPPED'
        return (category, short, verbose)
    category = report.outcome
    verbose = category.upper()
    return (category, short, verbose)

现在运行测试将不会打印任何简短的结果字母（.sxFE）。该代码有点冗长，但是可以处理框架中定义的所有标准结果。

关闭详细结果

以详细模式运行时，pytest会打印结果以及测试用例名称：

$ pytest -sv
=================================== test session starts ===================================
...
test_spam.py::test_spam PASSED
test_spam.py::test_eggs FAILED
test_spam.py::test_bacon SKIPPED
test_spam.py::test_foo xfail
...

如果您从上述钩子印象中删除设置verbose的行（将其设置为空字符串），则pytest还将停止以详细模式打印结果：

import pytest

def pytest_report_teststatus(report):
    category, short, verbose = '', '', ''
    if hasattr(report, 'wasxfail'):
        if report.skipped:
            category = 'xfailed'
        elif report.passed:
            category = 'xpassed'
        return (category, short, verbose)
    elif report.when in ('setup', 'teardown'):
        if report.failed:
            category = 'error'
        elif report.skipped:
            category = 'skipped'
        return (category, short, verbose)
    category = report.outcome
    return (category, short, verbose)

$ pytest -sv
=================================== test session starts ===================================
...
test_spam.py::test_spam
test_spam.py::test_eggs
test_spam.py::test_bacon
test_spam.py::test_foo
...

通过命令行开关引入自定义报告模式

当从命令行传递--silent标志时，以下示例将关闭同时打印简短和冗长的结果：

import pytest

def pytest_addoption(parser):
    parser.addoption('--silent', action='store_true', default=False)


def pytest_report_teststatus(report):
    category, short, verbose = '', '', ''
    if not pytest.config.getoption('--silent'):
        return None

    if hasattr(report, 'wasxfail'):
        if report.skipped:
            category = 'xfailed'
        elif report.passed:
            category = 'xpassed'
        return (category, short, verbose)
    elif report.when in ('setup', 'teardown'):
        if report.failed:
            category = 'error'
        elif report.skipped:
            category = 'skipped'
        return (category, short, verbose)
    category = report.outcome
    return (category, short, verbose)

Answer 2

使用我的插件pytest-custom-report，您可以通过在报告中使用空字符串标记来轻松隐藏这些点。

pip install pytest-custom-report
pytest -q --report-passed=""
