赛普拉斯:在多个API测试中重复使用身份验证令牌

标签: javascript rest api automation cypress

我有一个生成令牌的Rest API。此会话令牌在多个REST API中用作授权 Bearer令牌。我以此为参考:https://github.com/cypress-io/cypress-example-recipes/blob/master/examples/logging-in__jwt/cypress/integration/spec.js

但是,在该示例中,生成令牌的功能嵌入在测试中。我试图创建一个应在本地存储的自定义命令,但测试未将其拾取。请注意,自定义命令中没有返回值。

我的以下代码位于 support / commands.js 下:

let identity
Cypress.Commands.add('postToken', () => {
    cy.request({
        method: 'POST',
        url: Cypress.env('api_identity_url'), //get from cypress.env.json
        form: true, //sets to application/x-www-form-urlencoded
        body: {
            grant_type: 'client_credentials',
            scope: 'xero_all-apis'
        },
        auth: {
            username: Cypress.env('api_identity_username'),
            password: Cypress.env('api_identity_password')
        }
    })
        .its('body')
        .then((response) => {
            identity = response
            window.localStorage.setItem('identity', JSON.stringify(identity))
            cy.log(identity.access_token)
        })
})

我的测试

context('Check token details', () => {
  it('Check token', () => {
      cy.postToken()
      const bToken = window.localStorage.getItem('identity')
      cy.log(bToken)
  })
})

当我运行测试时,日志显示“身份”的null值。但是,它在我放置cy.log(identity.access_token)的自定义命令中显示了当前值 我尝试使用 cy.writeFile ,但我认为这不是一个干净的方法。必须在函数和不同的类之间传递某种数据。

示例JSON格式:

{
  "token": "<this is the value I would like to use for other API's authorisation bearer token>",
  "expires_in": 1200,
  "token_type": "Bearer"
}

您可以使用cypress-localstorage-commands包在测试之间持久化localStorage。

support/commands.js中:

import "cypress-localstorage-commands";

Cypress.Commands.add('postToken', () => {
  cy.request({
    method: 'POST',
    url: Cypress.env('api_identity_url'), //get from cypress.env.json
    form: true, //sets to application/x-www-form-urlencoded
    body: {
      grant_type: 'client_credentials',
      scope: 'xero_all-apis'
    },
    auth: {
      username: Cypress.env('api_identity_username'),
      password: Cypress.env('api_identity_password')
    }
  })
  .its('body')
  .then(identity => {
    cy.setLocalStorage("identity_token", identity.token);
  });
});

测试内部:

describe("postToken", ()=> {
  before(() => {
    cy.postToken();
    cy.saveLocalStorage();
  });

  beforeEach(() => {
    cy.restoreLocalStorage();
  });

  it("should exist identity in localStorage", () => {
    cy.getLocalStorage("identity_token").should("exist");
    cy.getLocalStorage("identity_token").then(token => {
      console.log("Identity token", token);
    });
  });

  it("should still exist identity in localStorage", () => {
    cy.getLocalStorage("identity_token").should("exist");
    cy.getLocalStorage("identity_token").then(token => {
      console.log("Identity token", token);
    });
  });
});

感谢哈维尔为我展示了cypress-localstorage-commands软件包。我开始使用它。在那之前,我曾经这样获得过登录令牌。

describe('Record audit', () => {
    let token = null;

    before(() => {
        cy.login().then((responseToken) => { // or postToken() in your case
            token = responseToken;
        });
    });

    it('I can use the token here', () => {
        cy.log(token);
    });
});

唯一的区别是我的login命令返回令牌。在您的代码中应该看起来像这样

// commands.js

.then((response) => {
    identity = response
    window.localStorage.setItem('identity', JSON.stringify(identity))
    cy.log(identity.access_token)
    return identity.access_token
})

我在commmand.js中使用了这段代码

<table>

在测试后添加以下代码

var headers_login = new Headers()
headers_login.append('Content-Type', 'application/json')

Cypress.Commands.add('get_token', (username, password)=>{
var token = ""
cy.request({
    method: 'POST',
    url: Cypress.env("api") + "users/getToken",
    failOnStatusCode: false,
    json: true,
    form: true,
    body: {username: username, password: password},
    headers: headers_login
 }).then((json) => {
    //cy.setLocalStorage('token', json.body.response.data.token)   
    token = json.body.response.data.token
    return token;
 }) })
