开玩笑--findRelatedTests未找到相关测试

Question

运行命令jest --bail --findRelatedTests src/components/BannerSet/BannerSet.tsx 时，我收到以下消息：

No tests found, exiting with code 1
Run with `--passWithNoTests` to exit with code 0
No files found in C:\Users\user\code\repo.
Make sure Jest's configuration does not exclude this directory.
To set up Jest, make sure a package.json file exists.
Jest Documentation: facebook.github.io/jest/docs/configuration.html
Pattern: .\\src\\components\\BannerSet\\BannerSet.tsx - 0 matches

但是我确实准备好了文件：

src/components/BannerSet/BannerSet.test.tsx
src/components/BannerSet/BannerSet.tsx

为什么Jest无法找到相关测试？仅运行jest即可正常运行。
