Using Playwright in Vue projects is mainly used for end-to-end (E2E) testing. 1. Install Playwright to execute commands through npm or yarn and select the default configuration to start; 2. When writing tests, place the test files in the tests/ directory, and use APIs such as page.goto(), click() and expect() to verify page interaction; 3. For Vue Router and Vuex, Playwright can simulate real behavior, test routing jumps and state changes, and improve test stability by intercepting API requests; 4. When debugging, you can use the --headed parameter or playwright show-trace to view the execution process; 5. It is recommended to add test commands to the scripts of package.json for call.
Use Playwright in Vue projects is mainly for end-to-end (E2E) testing. Playwright is a powerful automated testing tool that supports multi-browser, multi-tab page, intercept network requests and other features, which is very suitable for testing the interactive logic and page behavior of Vue applications.
Install Playwright
First you need to install Playwright in the Vue project. If you are using Vue CLI or Vite, you can install it directly through npm or yarn:
npm init playwright@latest
or:
yarn create playwright
This command will guide you through some configuration options, such as whether TypeScript support is required, test location storage paths, whether browser UI is enabled, etc. It is recommended to select the default configuration to start, and then adjust it as needed.
Write the first E2E test
Playwright will look for test files in tests/ directory by default. You can create a simple test to verify the basic functionality of Vue pages.
For example: Suppose you have a component that changes the text content after clicking a button, you can write a test like this:
// tests/example.spec.ts
import { test, expect } from '@playwright/test';
test('button should update text', async ({ page }) => {
await page.goto('http://localhost:5173'); // Replace with your local development address await page.click('button');
await expect(page.locator('p')).toHaveText('Clicked');
});The key points here are:
- Use
page.goto()to access the page - Use
click()to simulate user click - Verify the result with
expect().toHaveText()
Playwright's API is very intuitive, and most operations are as concise and clear as above.
Work with Vue Router/Vuex
If your Vue project uses Vue Router or Vuex, Playwright can also handle it. It essentially simulates the behavior of the real browser, so routing jumps and status updates can be detected normally.
Common practices include:
- Test whether the route jump is triggered correctly
- Verify that page elements change with Vuex status
- Intercept API requests and simulate specific response data for boundary testing
For example, intercept API requests:
await page.route('**/api/data', route =>
route.fulfill({
status: 200,
contentType: 'application/json',
body: JSON.stringify({ items: ['Vue', 'Playwright'] }),
})
);This can prevent tests from relying on real interfaces, improving stability and execution speed.
Debugging and running methods
When debugging Playwright tests, you can view the browser interface in the following ways:
npx playwright show-trace
Or directly add the --headed parameter to run the test:
npx playwright test --headed
This will open a browser window, allowing you to see the test execution process, which is convenient for troubleshooting problems.
In addition, it is recommended to add test scripts to package.json :
"scripts": {
"test:e2e": "playwright test",
"test:e2e:debug": "playwright test --headed"
}This makes it easier to call.
Basically that's it. Playwright is not difficult to get started, but it still requires reasonable design of the test structure and assertion logic to complete coverage in a SPA like Vue.

What is headless UI in Vue?
Jul 08, 2025 am 01:38 AM
HeadlessUIinVue refers to a library of UI components that provide no preset styles and only contains core logic and behavior. Its features include: 1. No style restrictions, developers can customize the design; 2. Focus on barrier-free and interactive logic, such as keyboard navigation, state management, etc.; 3. Support Vue framework integration, exposing the control interface through combinable functions or components. Reasons for use include: maintaining design consistency, built-in accessibility, strong component reusability, and lightweight library size. In practical applications, developers need to write HTML and CSS themselves. For example, when building a drop-down menu, the library handles state and interaction, while developers decide on visual presentation. Mainstream libraries include HeadlessUI and RadixVue for TailwindLabs, suitable for
How to watch nested properties in Vue 3?
Jul 07, 2025 am 12:51 AM
In Vue3, there are three ways to monitor nested properties using the watch function: 1. Use the getter function to accurately monitor specific nested paths, such as watch(()=>someObject.nested.property,callback); 2. Add the {deep:true} option to deeply monitor changes within the entire object, which is suitable for situations where the structure is complex and does not care about which property changes; 3. Return an array in the getter to listen to multiple nested values ??at the same time, which can be used in combination with deep:true; in addition, if ref is used, the nested properties in its .value need to be tracked through getter.

The structural design should be classified according to functional modules, including basic components, layout components and business components; 2. Use SCSS or CSS variables to unify the theme and style; 3. Unify the naming specifications and introduce ESLint and Prettier to ensure the consistent code style; 4. Display the usage of components on the supporting document site; 5. Use Vite and other tools to package as NPM packages and configure rollupOptions; 6. Follow the semver specification to manage versions and changelogs when publishing.
Key differences between Vue 2 and Vue 3?
Jul 09, 2025 am 01:29 AM
Vue3 has improved in many key aspects compared to Vue2. 1.Composition API provides a more flexible logical organization method, allowing centralized management of related logic, while still supporting Vue2's Options API; 2. Better performance and smaller package size, the core library is reduced by about 30%, the rendering speed is faster and supports better tree shake optimization; 3. The responsive system uses ES6Proxy to solve the problem of unable to automatically track attribute addition and deletion in Vue2, making the responsive mechanism more natural and consistent; 4. Built-in better support for TypeScript, support multiple node fragments and custom renderer API, improving flexibility and future adaptability. Overall, Vue3 is a smooth upgrade to Vue2,

How to define routes in vue router?
Jul 05, 2025 am 12:58 AM
Defining routes in Vue projects requires understanding the structure and configuration. The steps are as follows: 1. Install and introduce vue-router, create a routing instance, and pass in a routes array containing path and component; 2. Use dynamic routing matching such as /user/:id to obtain parameters; 3. Use children attribute to implement nested routes; 4. Name the routes with the name attribute for jumping; 5. Use redirect for path redirect. After mastering these core points, you can configure routing efficiently.
Benefits of using ?
Jul 08, 2025 am 12:20 AM
? in regular expressions are used to convert greedy matches to non-greedy, achieving more accurate matches. 1. It makes the content as little as possible to match as little as possible to avoid mismatch across tags or fields; 2. It is often used in scenarios such as HTML parsing, log analysis, URL extraction, etc. that require precise control of the scope; 3. When using it, it is necessary to note that not all quantifiers are applicable. Some tools need to manually enable non-greedy mode, and complex structures need to be combined with grouping and assertions to ensure accuracy. Mastering this technique can significantly improve text processing efficiency.
