Writing Tests in TypeScript with Playwright

Playwright, developed by Microsoft, is a powerful end-to-end testing framework that supports all modern browsers. When paired with TypeScript, it provides a robust and scalable environment for writing maintainable and type-safe test scripts.

TypeScript brings strong typing, autocompletion, and better tooling support, making your Playwright tests more reliable and easier to debug. Getting started is simple: install Playwright and TypeScript via npm. Next, initialize a project using npx playwright codegen or npx playwright init, which sets up the configuration, browsers, and example tests.

A basic test file in TypeScript might look like this:

ts

import { test, expect } from '@playwright/test';

test('homepage has title', async ({ page }) => {

  await page.goto('https://example.com');

  await expect(page).toHaveTitle(/Example Domain/);

});

The test method defines the test case, while expect is used for assertions. Playwright’s powerful APIs like page, locator, and browserContext allow precise control and isolation for each test.

To run TypeScript tests, Playwright uses its built-in test runner. The TypeScript compiler (tsc) converts .ts files into JavaScript before execution. You can also use tools like ts-node for on-the-fly transpilation.

In conclusion, combining Playwright with TypeScript enhances your testing process through better code quality, maintainability, and developer experience — making it an ideal stack for frontend automation.
