PureScript 语言 端到端测试 E2E Testing 集成 Cypress/Playwright 前端 + 后端流程

Cypress/Playwright 集成 PureScript 端到端测试（E2E Testing）

随着前端技术的不断发展，前端测试变得越来越重要。端到端测试（End-to-End Testing，简称E2E测试）是确保应用程序在用户环境中正常工作的一种测试方法。本文将探讨如何使用 Cypress 和 Playwright 集成 PureScript 语言进行端到端测试。

PureScript 是一种函数式编程语言，它基于 Haskell，旨在提高代码的可读性和可维护性。Cypress 和 Playwright 是两种流行的端到端测试框架，它们可以与多种前端技术集成。本文将介绍如何将 Cypress 和 Playwright 集成到 PureScript 项目中，以实现端到端测试。

环境搭建

在开始之前，我们需要搭建一个支持 PureScript、Cypress 和 Playwright 的开发环境。

安装 Node.js 和 npm

确保你的计算机上安装了 Node.js 和 npm。你可以从 [Node.js 官网](https://nodejs.org/) 下载并安装。

创建 PureScript 项目

使用 `purescript-create` 工具创建一个新的 PureScript 项目：

bash
npx purescript-create my-purescript-app
cd my-purescript-app


安装 Cypress 和 Playwright

在你的 PureScript 项目目录中，安装 Cypress 和 Playwright：

bash
npm install cypress playwright cypress-playwright


配置 Cypress

创建一个 `cypress.config.js` 文件，配置 Cypress：

javascript
const { defineConfig } = require('cypress');

module.exports = defineConfig({
fixturesFolder: 'src/fixtures',
screenshotsFolder: 'src/screenshots',
videosFolder: 'src/videos',
viewportWidth: 1280,
viewportHeight: 720,
// 其他配置...
});


配置 Playwright

创建一个 `playwright.config.js` 文件，配置 Playwright：

javascript
const { defineConfig } = require('@playwright/test');

module.exports = defineConfig({
testDir: 'src/e2e',
outputDir: 'src/e2e/results',
timeout: 30 1000,
// 其他配置...
});


编写端到端测试

使用 Cypress 编写测试

在 `src/e2e` 目录下，创建一个测试文件 `example_spec.purs`：

```purescript
module E2ETest where

import Test (Spec, describe, it, expect)
import Effect (Effect)
import Effect.Aff (Aff)
import Effect.Class (liftEffect)
