Cypress多环境测试：如何通过JSON读取环境值复用测试数据

一、调整JSON文件结构 #

先按你的需求重构两个JSON文件，把不同环境的配置和测试数据分别归类：

修改后的credentials.json #

{
  "environment": "stage",
  "stage": {
    "url": "stage.site.url",
    "sausername": "stage-sausername",
    "sapassword": "stage-sapassword",
    "viewonlyusername": "stage-vouusername",
    "viewonlypassword": "stage-voupassword"
  },
  "test": {
    "url": "test.site.url",
    "sausername": "test-sausername",
    "sapassword": "test-sapassword",
    "viewonlyusername": "test-vouusername",
    "viewonlypassword": "test-voupassword"
  }
}

修改后的SuperAdminTestData.json #

{
  "stage": {
    "accountName": "stage-account name",
    "PartnerAdminAccount": "Automation Partner (Stage)",
    "WholesalePartnerAccount": "Automation Wholesale Partner (Stage)",
    "mitelAccountName": "Platform name (Stage)",
    "siteName": "stage-site name"
  },
  "test": {
    "accountName": "test-account name",
    "PartnerAdminAccount": "Automation Partner (Test)",
    "WholesalePartnerAccount": "Automation Wholesale Partner (Test)",
    "mitelAccountName": "Platform name (Test)",
    "siteName": "test-site name"
  }
}

二、修改测试脚本（SuperAdminSpec.js） #

调整before钩子的逻辑，先读取环境配置，再自动匹配对应环境的测试数据：

describe("Super Admin - User Roles and Permissions", function () {
  let currentEnvCredentials, currentEnvTestData;

  before(function () {
    // 先读取凭证文件，获取当前指定的环境
    cy.fixture('credentials').then((credentials) => {
      // 统一转小写，避免大小写不匹配问题
      const currentEnv = credentials.environment.toLowerCase();
      // 取出当前环境的凭证
      currentEnvCredentials = credentials[currentEnv];

      // 根据当前环境，读取对应测试数据
      cy.fixture('SuperAdminTestData').then((allTestData) => {
        currentEnvTestData = allTestData[currentEnv];
      });
    });
  });

  it("Login with valid credentials", function () {
    loginfunction(currentEnvCredentials.url, currentEnvCredentials.sausername, currentEnvCredentials.sapassword);
  });

  it('Navigate to Partner Admin account', function () {
    clickAllcustomers();
    clickCustomer(currentEnvTestData.PartnerAdminAccount);
  });
});

三、关键说明 #

• 大小写兼容：把environment的值转成小写，避免JSON里stage和Stage这类大小写差异导致的匹配失败
• 异步顺序：利用Cypress fixture的异步链式调用，确保先拿到环境名称，再去读取对应环境的测试数据
• 切换环境：只需要修改credentials.json里的"environment": "stage"为"environment": "test"，所有测试就会自动切换到对应环境的配置和数据
