实习生异步测试

Intern Async Test

本文关键字：测试 异步 实习生      更新时间：2023-09-26

我正在尝试使用单独的模块进行异步实习生测试来执行请求调用。测试完成后，我遇到了返回 true 的问题，因为即使请求成功并且测试运行完成，我总是收到超时错误。测试运行后，它只是位于最后一页并超时。login_test.js是测试文件，CompanyCreate 是存在于外部模块中的请求调用文件。我不太确定如果我将我的测试返回调用传递给 deferred.callback（） 会发生什么。

// login_test.js
define([
'intern!object',
'pages/loginpage',
'runtime/testConfig',
'intern/dojo/node!nconf',
'helpers/companyCreate',
'locators/loginpage',
'locators/companyselectionpage'
], function(registerSuite, LoginPage, conf, nconf, Company) {
var tests = {
    name: 'Login test',
    'Test': function() {
        /* make a call to create a company
        * param1: test function to run after we get response with login details
        * param2: intern object so we can make it async
        */
        Company.createCompany(function(response, testObj) {
            testObj.timeout = 120000; //The default timeout is 30 seconds. Not enough
            var region = nconf.get("region"); //Getting command line region value
            var regionData = conf.get(region); //Fetching  config data based on region
            var loginId = regionData.LOGIN;
            var password = regionData.PASSWORD;
            var loginPage = new LoginPage(testObj.remote, regionData.DEFAULT_TIMEOUT);
            var companySelectionPage = loginPage
                .load(regionData.BASE_URL)
                .loginIn(loginId, password);
            var homePage = companySelectionPage
                .doesCurrentURLContain('/companysel')
                .isTitlePresent()
                .selectCompany(CompanySelectionLocators.data);
            return homePage
                .doesCurrentURLContain('/homepage')
                .getAccumulatedState();
        }, this);
    }
};
registerSuite(tests);
});

// companyCreate.js
define(function(require) {
var request = require('intern/dojo/request');
var Company = {
    createCompany: function(callbackArg, testObj) {
        // tell intern this is async
        var deferred = testObj.async(120000);
        // make post
        request.post('https://internal.com/createcompany', {
            query: {
                version: ".0.1",
                special: "true"
            },
            data: JSON.stringify({
                userName: "Test",
                password: "pass",
                userEmail: "email@hi.com"
            }),
            headers: {
                'Content-Type': "application/json"
            }
        }).then(function(response) {
            // success, tell intern async is done, return test function to run and pass it the response
            console.log(response);
            return deferred.callback(callbackArg(response, testObj));
        }, function(err) {
            console.log(err);
        }, function(evt) {
            //console.log(evt);
        });
    }
};
return Company;
});
deferred.callback旨在

用于包装在其他时间执行的另一个回调。它不会解析基础 Promise，它会返回一个新函数，在调用该函数时，如果传入的回调函数未引发错误，则会解析 Promise。例如：

'Test': function () {
  var dfd = this.async();
  // this use of `dfd.callback`…
  fs.readFile('foo.txt', dfd.callback(function (error, data) {
    if (error) {
      throw error;
    }
    assert.strictEqual(data, 'hello, world');
  }));
  // …is equivalent to this without it:
  fs.readFile('foo.txt', function (error, data) {
    if (error) {
      dfd.reject(error);
      return;
    }
    try {
      assert.strictEqual(data, 'hello, world');
    }
    catch (error) {
      dfd.reject(error);
      return;
    }
    dfd.resolve();
  }));
}

您应该使用 deferred.resolve ，它将承诺解析为作为第一个参数传递的值。有关每个函数的更多详细信息，请参阅异步测试文档。

工作解决方案如下。 我不需要这个.async。 comapnyCreate.js 返回来自请求的响应和承诺。login_test.js在履行承诺后运行测试。 （仍然需要一些错误处理逻辑）

// login_test.js

    'locators/companyselectionpage'
], function(registerSuite, LoginPage, conf, nconf, Company) {
var tests = {
    name: 'Login test',
    'Test': function() {
        this.timeout = 60000;
        var remote = this.remote;
        return Company.createCompany().then(function(response) {
            var region = nconf.get("region"); //Getting command line region value
            var regionData = conf.get(region); //Fetching  config data based on region
            var loginId = regionData.LOGIN;
            var password = regionData.PASSWORD;
            var loginPage = new LoginPage(remote, regionData.DEFAULT_TIMEOUT);
            var companySelectionPage = loginPage
