Playwright 测试

Playwright Test 提供了 test 函数来声明测试和 expect 函数来编写断言。

¥Playwright Test provides a test function to declare tests and expect function to write assertions.

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

test('basic test', async ({ page }) => {
  await page.goto('https://playwright.nodejs.cn/');
  const name = await page.innerText('.navbar__title');
  expect(name).toBe('Playwright');
});

用法

¥Usage

首先定义一个夹具和/或一个选项。

¥First define a fixture and/or an option.

TypeScript
JavaScript

import { test as base } from '@playwright/test';
import { TodoPage } from './todo-page';

export type Options = { defaultItem: string };

// Extend basic test by providing a "defaultItem" option and a "todoPage" fixture.
export const test = base.extend<Options & { todoPage: TodoPage }>({
  // Define an option and provide a default value.
  // We can later override it in the config.
  defaultItem: ['Do stuff', { option: true }],

  // Define a fixture. Note that it can use built-in fixture "page"
  // and a new option "defaultItem".
  todoPage: async ({ page, defaultItem }, use) => {
    const todoPage = new TodoPage(page);
    await todoPage.goto();
    await todoPage.addToDo(defaultItem);
    await use(todoPage);
    await todoPage.removeAll();
  },
});

my-test.js
const base = require('@playwright/test');
const { TodoPage } = require('./todo-page');

// Extend basic test by providing a "defaultItem" option and a "todoPage" fixture.
exports.test = base.test.extend({
  // Define an option and provide a default value.
  // We can later override it in the config.
  defaultItem: ['Do stuff', { option: true }],

  // Define a fixture. Note that it can use built-in fixture "page"
  // and a new option "defaultItem".
  todoPage: async ({ page, defaultItem }, use) => {
    const todoPage = new TodoPage(page);
    await todoPage.goto();
    await todoPage.addToDo(defaultItem);
    await use(todoPage);
    await todoPage.removeAll();
  },
});

然后在测试中使用夹具。

¥Then use the fixture in the test.

example.spec.ts
import { test } from './my-test';

test('test 1', async ({ todoPage }) => {
  await todoPage.addToDo('my todo');
  // ...
});

配置配置文件中的选项。

¥Configure the option in config file.

TypeScript
JavaScript

playwright.config.ts
import { defineConfig } from '@playwright/test';
import type { Options } from './my-test';

export default defineConfig<Options>({
  projects: [
    {
      name: 'shopping',
      use: { defaultItem: 'Buy milk' },
    },
    {
      name: 'wellbeing',
      use: { defaultItem: 'Exercise!' },
    },
  ]
});

playwright.config.ts
// @ts-check

module.exports = defineConfig({
  projects: [
    {
      name: 'shopping',
      use: { defaultItem: 'Buy milk' },
    },
    {
      name: 'wellbeing',
      use: { defaultItem: 'Exercise!' },
    },

¥An object containing fixtures and/or options. Learn more about fixtures format.

¥Returns

Test #

test.fail

Added in: v1.10

test.test.fail

将测试标记为 "应该失败"。Playwright 运行此测试并确保它确实失败。这对于文档目的很有用，可以确认某些功能在修复之前已损坏。

¥Marks a test as "should fail". Playwright runs this test and ensures that it is actually failing. This is useful for documentation purposes to acknowledge that some functionality is broken until it is fixed.

声明 "failing" 测试：

¥To declare a "failing" test:

test.fail(title, body)
test.fail(title, details, body)

要在运行时将测试注释为 "failing"：

¥To annotate test as "failing" at runtime:

test.fail(condition, description)
test.fail(callback, description)
test.fail()

用法

¥Usage

你可以将测试声明为失败，以便 Playwright 确保它确实失败。

¥You can declare a test as failing, so that Playwright ensures it actually fails.

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

test.fail('not yet ready', async ({ page }) => {
  // ...
});

如果你的测试在某些配置（但不是全部）中失败，你可以根据某些条件在测试主体内将测试标记为失败。我们建议在这种情况下传递 description 参数。

¥If your test fails in some configurations, but not all, you can mark the test as failing inside the test body based on some condition. We recommend passing a description argument in this case.

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

test('fail in WebKit', async ({ page, browserName }) => {
  test.fail(browserName === 'webkit', 'This feature is not implemented for Mac yet');
  // ...
});

你可以根据某些条件，使用单个 test.fail(callback, description) 调用将文件或 test.describe() 组中的所有测试标记为 "应该失败"。

¥You can mark all tests in a file or test.describe() group as "should fail" based on some condition with a single test.fail(callback, description) call.

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

test.fail(({ browserName }) => browserName === 'webkit', 'not implemented yet');

test('fail in WebKit 1', async ({ page }) => {
  // ...
});
test('fail in WebKit 2', async ({ page }) => {
  // ...
});

你还可以在测试主体内调用不带参数的 test.fail()，以始终将测试标记为失败。我们建议改为使用 test.fail(title, body) 来声明失败的测试。

¥You can also call test.fail() without arguments inside the test body to always mark the test as failed. We recommend declaring a failing test with test.fail(title, body) instead.

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

test('less readable', async ({ page }) => {
  test.fail();
  // ...
});

test.fixme

Added in: v1.10

test.test.fixme

将测试标记为 "fixme"，旨在修复它。Playwright 将不会在 test.fixme() 调用之后运行测试。

¥Mark a test as "fixme", with the intention to fix it. Playwright will not run the test past the test.fixme() call.

声明 "fixme" 测试：

¥To declare a "fixme" test:

test.fixme(title, body)
test.fixme(title, details, body)

要在运行时将测试注释为 "fixme"：

¥To annotate test as "fixme" at runtime:

test.fixme(condition, description)
test.fixme(callback, description)
test.fixme()

用法

¥Usage

你可以声明一个测试已修复，而 Playwright 不会运行它。

¥You can declare a test as to be fixed, and Playwright will not run it.

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

test.fixme('to be fixed', async ({ page }) => {
  // ...
});

如果你的测试应该在某些配置（但不是全部）中修复，你可以根据某些条件在测试主体内将测试标记为 "fixme"。我们建议在这种情况下传递 description 参数。Playwright 将运行测试，但在 test.fixme 调用后立即中止它。

¥If your test should be fixed in some configurations, but not all, you can mark the test as "fixme" inside the test body based on some condition. We recommend passing a description argument in this case. Playwright will run the test, but abort it immediately after the test.fixme call.

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

test('to be fixed in Safari', async ({ page, browserName }) => {
  test.fixme(browserName === 'webkit', 'This feature breaks in Safari for some reason');
  // ...
});

你可以根据某些条件，使用单个 test.fixme(callback, description) 调用将文件或 test.describe() 组中的所有测试标记为 "fixme"。

¥You can mark all tests in a file or test.describe() group as "fixme" based on some condition with a single test.fixme(callback, description) call.

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

test.fixme(({ browserName }) => browserName === 'webkit', 'Should figure out the issue');

test('to be fixed in Safari 1', async ({ page }) => {
  // ...
});
test('to be fixed in Safari 2', async ({ page }) => {
  // ...
});

你还可以在测试主体内调用不带参数的 test.fixme()，以始终将测试标记为失败。我们建议使用 test.fixme(title, body)。

¥You can also call test.fixme() without arguments inside the test body to always mark the test as failed. We recommend using test.fixme(title, body) instead.

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

test('less readable', async ({ page }) => {
  test.fixme();
  // ...
});

test.skip

Added in: v1.10

test.test.skip

跳过测试。Playwright 将不会在 test.skip() 调用之后运行测试。

¥Skip a test. Playwright will not run the test past the test.skip() call.

跳过的测试不应该运行。如果你打算修复测试，请改用 test.fixme()。

¥Skipped tests are not supposed to be ever run. If you intent to fix the test, use test.fixme() instead.

要声明跳过的测试：

¥To declare a skipped test:

test.skip(title, body)
test.skip(title, details, body)

要在运行时跳过测试：

¥To skip a test at runtime:

test.skip(condition, description)
test.skip(callback, description)

用法

¥Usage

你可以声明跳过的测试，Playwright 将不会运行它。

¥You can declare a skipped test, and Playwright will not run it.

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

test.skip('never run', async ({ page }) => {
  // ...
});

如果你的测试应该在某些配置中跳过，但不是全部，你可以根据某些条件跳过测试主体内的测试。我们建议在这种情况下传递 description 参数。Playwright 将运行测试，但在 test.skip 调用后立即中止它。

¥If your test should be skipped in some configurations, but not all, you can skip the test inside the test body based on some condition. We recommend passing a description argument in this case. Playwright will run the test, but abort it immediately after the test.skip call.

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

test('Safari-only test', async ({ page, browserName }) => {
  test.skip(browserName !== 'webkit', 'This feature is Safari-only');
  // ...
});

你可以根据某些条件，使用单个 test.skip(callback, description) 调用跳过文件或 test.describe() 组中的所有测试。

用法

¥Usage

你可以通过在测试主体内调用 test.slow() 将测试标记为慢。

¥You can mark a test as slow by calling test.slow() inside the test body.

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

test('slow test', async ({ page }) => {
  test.slow();
  // ...
});

如果你的测试在某些配置（但不是全部）中运行缓慢，你可以根据条件将其标记为运行缓慢。我们建议在这种情况下传递 description 参数。

¥If your test is slow in some configurations, but not all, you can mark it as slow based on a condition. We recommend passing a description argument in this case.

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

¥Whether to box the step in the report. Defaults to false. When the step is boxed, errors thrown from the step internals point to the step call site. See below for more details.

¥Returns

Promise<Object>#

细节

¥Details

该方法返回步骤回调返回的值。

¥The method returns the value returned by the step callback.

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

test('test', async ({ page }) => {
  const user = await test.step('Log in', async () => {
    // ...
    return 'john';
  });
  expect(user).toBe('john');
});

装饰器

¥Decorator

你可以使用 TypeScript 方法装饰器将方法转变为步骤。对修饰方法的每次调用都将显示为报告中的一个步骤。

¥You can use TypeScript method decorators to turn a method into a step. Each call to the decorated method will show up as a step in the report.

function step(target: Function, context: ClassMethodDecoratorContext) {
  return function replacementMethod(...args: any) {
    const name = this.constructor.name + '.' + (context.name as string);
    return test.step(name, async () => {
      return await target.call(this, ...args);
    });
  };
}

class LoginPage {
  constructor(readonly page: Page) {}

  @step
  async login() {
    const account = { username: 'Alice', password: 's3cr3t' };
    await this.page.getByLabel('Username or email address').fill(account.username);
    await this.page.getByLabel('Password').fill(account.password);
    await this.page.getByRole('button', { name: 'Sign in' }).click();
    await expect(this.page.getByRole('button', { name: 'View profile and more' })).toBeVisible();
  }
}

test('example', async ({ page }) => {
  const loginPage = new LoginPage(page);
  await loginPage.login();
});

装入盒中

¥Boxing

当步骤内的某些内容失败时，你通常会看到错误指向失败的确切操作。例如，考虑以下登录步骤：

¥When something inside a step fails, you would usually see the error pointing to the exact action that failed. For example, consider the following login step:

async function login(page) {
  await test.step('login', async () => {
    const account = { username: 'Alice', password: 's3cr3t' };
    await page.getByLabel('Username or email address').fill(account.username);
    await page.getByLabel('Password').fill(account.password);
    await page.getByRole('button', { name: 'Sign in' }).click();
    await expect(page.getByRole('button', { name: 'View profile and more' })).toBeVisible();
  });
}

test('example', async ({ page }) => {
  await page.goto('https://github.com/login');
  await login(page);
});

Error: Timed out 5000ms waiting for expect(locator).toBeVisible()
  ... error details omitted ...

   8 |     await page.getByRole('button', { name: 'Sign in' }).click();
>  9 |     await expect(page.getByRole('button', { name: 'View profile and more' })).toBeVisible();
     |                                                                               ^
  10 |   });

正如我们在上面看到的，测试可能会失败，并出现指向步骤内部的错误。如果你希望错误高亮 "login" 步骤而不是其内部，请使用 box 选项。装箱步骤内的错误指向步骤调用站点。

¥As we see above, the test may fail with an error pointing inside the step. If you would like the error to highlight the "login" step instead of its internals, use the box option. An error inside a boxed step points to the step call site.

async function login(page) {
  await test.step('login', async () => {
    // ...
  }, { box: true });  // Note the "box" option here.
}

Error: Timed out 5000ms waiting for expect(locator).toBeVisible()
  ... error details omitted ...

  14 |   await page.goto('https://github.com/login');
> 15 |   await login(page);
     |         ^
  16 | });

你还可以为盒装步骤创建 TypeScript 装饰器，类似于上面的常规步骤装饰器：

¥You can also create a TypeScript decorator for a boxed step, similar to a regular step decorator above:

function boxedStep(target: Function, context: ClassMethodDecoratorContext) {
  return function replacementMethod(...args: any) {
    const name = this.constructor.name + '.' + (context.name as string);
    return test.step(name, async () => {
      return await target.call(this, ...args);
    }, { box: true });  // Note the "box" option here.
  };
}

class LoginPage {
  constructor(readonly page: Page) {}

  @boxedStep
  async login() {
    // ....
  }
}

test('example', async ({ page }) => {
  const loginPage = new LoginPage(page);
  await loginPage.login();  // <-- Error will be reported on this line.
});

test.use

Added in: v1.10

test.test.use

指定要在单个测试文件或 test.describe() 组中使用的选项或装置。最有用的是设置一个选项，例如设置 locale 来配置 context 夹具。

¥Specifies options or fixtures to use in a single test file or a test.describe() group. Most useful to set an option, for example set locale to configure context fixture.

用法

¥Usage

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

test.use({ locale: 'en-US' });

test('test with locale', async ({ page }) => {
  // Default context and page have locale as specified
});

参数

¥Arguments

options TestOptions #

具有本地选项的对象。

¥An object with local options.

细节

¥Details

test.use 可以在全局作用域内调用，也可以在 test.describe 内部调用。在 beforeEach 或 beforeAll 内调用是错误的。

¥test.use can be called either in the global scope or inside test.describe. It is an error to call it within beforeEach or beforeAll.

还可以通过提供函数来覆盖夹具。

¥It is also possible to override a fixture by providing a function.

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

test.use({
  locale: async ({}, use) => {
    // Read locale from some configuration file.
    const locale = await fs.promises.readFile('test-locale', 'utf-8');
    await use(locale);
  },
