python之避免打印点

我使用选项 -q 运行 pytest。

不幸的是，这会打印出很多点。示例:

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

有没有办法避免这一长串的点和“s”字符？

更新

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

请您参考如下方法:

冗长选项无法关闭测试结果打印。但是，可以通过多种方式自定义 pytest，包括输出结果。要更改此设置，您将覆盖 pytest_report_teststatus钩子(Hook)。

关闭短字母

创建一个包含以下内容的文件 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)。代码有点冗长，但可以处理框架中定义的所有标准结果。

关闭详细结果

在详细模式下运行时，pytest 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 
... 

如果从上面的钩子(Hook)实现中删除设置 verbose 的行(将其设置为空字符串)，pytest 也将停止在详细模式下打印结果:

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，下面的示例将关闭打印简短和详细的结果:

import pytest 
 
def pytest_addoption(parser): 
    parser.addoption('--silent', action='store_true', default=False) 
 
 
def pytest_report_teststatus(report, config): 
    category, short, verbose = '', '', '' 
    if not 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)
