开始

安装

pnpm add -D @cronn/playwright-file-snapshots

npm install -D @cronn/playwright-file-snapshots

yarn add -D @cronn/playwright-file-snapshots

配置

定义可重复使用 expect 输出( 如: fixtures.ts:

import { defineFileSnapshotMatchers } from "@cronn/playwright-file-snapshots";

export const expect = defineFileSnapshotMatchers();

将输出目录添加到您的 .gitignore数字 :

# file snapshots
/data/test/output

写入测试

import { test } from "@playwright/test";

import { expect } from "./fixtures";

test("value is expected value", async () => {
  await expect({ value: "expected value" }).toMatchJsonFile();
});

产出(value_is_expected_value.json:

{
  "value": "expected value"
}
