描述

¥Description

禁止在包含测试的文件中使用 export 或 module.exports

¥Disallow using export or module.exports in files containing tests

此规则旨在通过从测试文件中导出内容来消除重复的测试运行。如果你从测试文件导入，则该文件中的所有测试都将在每个导入的实例中运行，因此最重要的是，不要从测试中导出，而是在需要在测试之间共享辅助函数时将其移动到单独的文件中。

¥This rule aims to eliminate duplicate runs of tests by exporting things from test files. If you import from a test file, then all the tests in that file will be run in each imported instance, so bottom line, don’t export from a test, but instead move helper functions into a separate file when they need to be shared across tests.
