how to only run .TS tests?

Answer

Sure, you can configure Playwright to only consider .ts files as test files. This is done by modifying the testConfig.testMatch option in the playwright.config.ts file.

By default, Playwright runs .test.(js|ts|mjs) and .spec.(js|ts|mjs) files. But you can change this. Say your .ts test files are in a "tests" directory and follow a "example.spec.ts" naming pattern. You can set testConfig.testMatch to 'tests/**/*.spec.ts'. This tells Playwright to only run .ts test files that match this pattern.

Here's how you can do this in your playwright.config.ts file:

import { defineConfig } from '@playwright/test';

export default defineConfig({
  // Other configuration options...

  testConfig: {
    // Other test configuration options...

    // Specify the glob pattern for .ts test files
    testMatch: 'tests/**/*.spec.ts',
  },
});

Now, when you run tests with Playwright, it will only consider and execute the .ts test files that match the specified glob pattern.

Remember, this information is based on the context provided. If there are other ways to configure Playwright for this purpose that aren't mentioned here, I'm not aware of them.
