对 AssertionError 重复测试 [英] Repeat a test upon an AssertionError

问题描述

有一个模块 pytest-repeat 可用于重复执行pytest N 次(整个测试套件).

There is the module pytest-repeat which can be used to repeat the execution of pytest N times (the whole test suite).

但是，我想在出现 AssertionError 时再次重新运行该特定测试，而不是运行整个套装.那么，如何捕获 AssertionError 并以编程方式调用相同的测试函数?

However, I want to, upon an AssertionError, re-run that specific test again, instead of running the whole suit. So, how can I capture the AssertionError and programmatically call the same test function?

推荐答案

flaky package 提供了一个 @flaky 装饰器.来自文档:

The flaky package provides a @flaky decorator. From the documentation:

@flaky(max_runs=3, min_passes=2)
def test_something_that_usually_passes(self):
    """This test must pass twice, and it can be run up to three times."""
    value_to_double = 21
    result = get_result_from_flaky_doubler(value_to_double)
    self.assertEqual(result, value_to_double * 2, 'Result doubled incorrectly.')
