https:\/\/playwright.dev\/docs\/codegen<\/a><\/p>\n\n\n\n

Installation:<\/p>\n\n\n\n

npm init playwright@latest<\/code><\/pre>\n\n\n\n
During installation, you’ll be prompted with several options. Here\u2019s an example of what I selected:<\/p>\n\n\n\n
Initializing project in '.'\nDo you want to use TypeScript or JavaScript? \u00b7 JavaScript\nWhere to put your end-to-end tests? \u00b7 tests\nAdd a GitHub Actions workflow? (y\/N) \u00b7 false\nInstall Playwright browsers (can be done manually via 'npx playwright install')? (Y\/n) \u00b7 true<\/code><\/pre>\n\n\n\n
Once installed, you can use the following commands from your project\u2019s root directory:<\/p>\n\n\n\n
npx playwright test\n    Runs the end-to-end tests.\n\nnpx playwright test --ui\n    Starts the interactive UI mode.\n\nnpx playwright test --project=chromium\n    Runs the tests only on Desktop Chrome.\n\nnpx playwright test example\n    Runs the tests in a specific file.\n\nnpx playwright test --debug\n    Runs the tests in debug mode.\n\nnpx playwright codegen\n    Auto generate tests with Codegen.<\/code><\/pre>\n\n\n\n
The installation also comes with an example folder, tests-examples<\/code>, which is really handy for getting a quick grasp of how to use this tool. Running the command npx playwright test example<\/code> will execute example test cases, and you\u2019ll see something like 6\/6 tests passing.<\/p>\n\n\n\n
The command npx playwright codegen<\/code> opens up an empty Codegen browser, but you can also specify a URL, like this:<\/p>\n\n\n\n
npx playwright codegen \"http:\/\/study.369usa.com\/demo.html\"<\/code><\/pre>\n\n\n\n
After playing around in the Codegen browser, it generates a list of actions in clean JavaScript for me:<\/p>\n\n\n\n
import { test, expect } from '@playwright\/test';\n\ntest('test', async ({ page }) => {\n  await page.goto('http:\/\/study.369usa.com\/demo.html');\n  await page.getByLabel('Number A:').click();\n  await page.getByLabel('Number A:').fill('1');\n  await page.getByLabel('Number B:').click();\n  await page.getByLabel('Number B:').fill('2');\n  await page.getByRole('button', { name: 'Add Numbers' }).click();\n  await expect(page.getByTestId('result')).toContainText('3');\n});<\/code><\/pre>\n\n\n\n
A special mention for the assertion parts: at the top of the Playwright Inspector, you’ll find three buttons\u2014Assert Visibility<\/strong>, Assert Text<\/strong>, and Assert Value<\/strong>\u2014to help with adding assertions without the need of writing a single line of your own code.<\/p>\n\n\n\n
Once the test is successfully generated, simply copy and paste it into a test file, name it xxxx.spec.js<\/code>, and run the command npx playwright test<\/code>. As expected, the single test I just created passed!<\/p>\n\n\n\n
Additionally, by running:<\/p>\n\n\n\n
npx playwright test --ui<\/code><\/pre>\n\n\n\n
You can even see the test steps play out one by one. You can control the steps, go back and forth, and interact with the simulated browser.<\/p>\n\n\n\n
