How do I configure Playwright to stop testing and exit when a certain number of test failures is reached?

Answer

Sure, you can configure Playwright to exit the test run if all tests pass. This is done using the maxFailures configuration option.

Here's how you can use it:

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

export default defineConfig({
  maxFailures: process.env.CI ? 1 : 0,
});

In this code snippet, maxFailures is set to 1 if the CI environment variable is defined, indicating a CI server run. Otherwise, it's set to 0.

This configuration ensures that if the number of test failures reaches or exceeds the maxFailures value, Playwright will stop executing further tests and exit with an error.

By default, maxFailures is set to 0, which means this behavior is disabled. So, if you want Playwright to exit when all tests pass without any failures, you need to set maxFailures in your configuration file.
