python – 避免打印点

我用选项-q运行pytest.

不幸的是,这打印出了很多点.例：

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

有没有办法避免这么长的点和“s”字符列表？

更新

有一个有效的答案.但不知何故,这对我来说太长了.我现在使用这个解决方法：我将此添加到调用pytest：pytest -q |的脚本中perl -pe’s / ^ [.sxFE] {20,} $// g’

解决方法:

详细程度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定制,包括结果打印.要更改此设置,您将覆盖pytest_report_teststatus挂钩.

关掉短信

使用以下内容创建文件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)

现在运行测试不会打印任何简短的结果字母(.sxFE).代码有点冗长,但处理框架中定义的所有标准结果.

关闭冗长的结果

在详细模式下运行时,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
...

如果从上面的钩子impl中删除设置verbose的行(将其设置为空字符串),pytest也将以详细模式停止打印结果：

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,以下示例将关闭打印短结果和详细结果：

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)
