【问题描述】：
我目前正在 Playwright 中编写测试。
我注意到控制台中有一个奇怪的输出：
TypeError: Cannot read property 'retry' of undefined
即使所有测试都通过了，我还是得到了这个，这会导致丑陋的额外输出：
这里是debug.log的内容：

但在其中找不到对retry 的任何引用。而在我的整个项目中，寻找retry，我只找到了这个：
最让我困惑的是，它只发生在几个测试中：当我将.only 附加到test 时，对某些人来说会发生，对某些人来说不会。但是无法找到这些测试之间的区别：我什至将某些测试的内容从非失败测试复制并粘贴到失败测试（替换失败测试），但它仍然失败。很奇怪。
【问题讨论】：
-
也许和这个有关，但你不定义我们就不知道了。在 playwright 配置中，您可以选择重试：“重试：”每次测试的最大重试尝试次数。另一方面不确定这是强制性配置。见playwright.dev/docs/test-configuration#testing-options
-
与此同时，问题奇迹般地消失了。不知道确切的时间和原因。如果它返回，会及时通知您。
