How do I configure the 'grepInvert' option in Playwright to ignore specific tags by default in a per-project setting?

Answer

Sure, you can force-call ignored tags in Playwright using the grepInvert option in your test project configuration. Here's how:

First, you need to set up your test project configuration file, typically named playwright.config.ts. This is where you define your test project settings.

// playwright.config.ts

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

const config: PlaywrightTestConfig = {
  // Other configuration options...
};
export default config;

Next, within this file, find the testProject object. Add a grepInvert property to it. Set its value to an array of regular expressions or a single regular expression pattern. These patterns represent the tags you want to ignore.

// playwright.config.ts

const config: PlaywrightTestConfig = {
  // Other configuration options...

  testProject: {
    // Other project settings...

    grepInvert: [/tag1/, /tag2/], // Specify the tags to be ignored
  },
};

In this example, tests with titles containing "tag1" or "tag2" will be ignored by default. This configuration is per-project and won't affect global configurations or other projects.

Remember, if no patterns are specified for exclusion using grepInvert, all tests will run, regardless of their tags.
