如何在Testcafe中记录Google Analytics（分析）通话？

标签： google-analytics testcafe

我正在尝试自动测试跟踪代码，并且正在使用the RequestLogger from Testcafé。我成功拦截了对example.com和localhost的呼叫，但没有拦截对https://www.google-analytics.com/的呼叫。可能是什么原因？

预期

此测试应为绿色

测试代码

import { RequestLogger } from 'testcafe';
const logger_ga = RequestLogger('https://www.google-analytics.com/');

fixture `localhost`
 .page('http://localhost:8000')

test  
   .requestHooks(logger_ga)
     ('logs calls to Google Analytics', async t => {
       await t.click("#ga-button");
       console.log(logger_ga.requests); // is empty due to timing
       await t.expect(logger_ga.contains(record => record.response.statusCode === 200)).ok();
});

此测试的固定装置

我正在通过index.html投放以下python -m SimpleHTTPServer 8000页

<!doctype html>
<html>

<head>
  <meta charset="utf-8">
  <title>Test page</title>
</head>

<body>
  <p>Hello world!</p>

  <!-- Google Analytics: change UA-XXXXX-Y to be your site's ID. -->
  <script>
    window.ga = function () { ga.q.push(arguments) }; ga.q = []; ga.l = +new Date;
    ga('create', 'UA-XXXXX-Y', 'auto'); ga('send', 'pageview')
  </script>
  <script src="https://www.google-analytics.com/analytics.js" async defer></script>

  <a onclick="ga('send', 'event', 'my_event_category', 'my_event_action', 'my_event_label');" href="#" id="ga-button">Google Analytics</a>
</body>

</html>

已观察

以上测试为红色

但是，这些测试是绿色的

import { RequestLogger } from 'testcafe';

const logger = RequestLogger('http://example.com');

fixture `example`
    .page('http://example.com');

test
    .requestHooks(logger)
    ('logs calls to example.com', async t => {
      await t.expect(logger.contains(record => record.response.statusCode === 200)).ok(); // green
});


const logger_localhost = RequestLogger('http://localhost:8000');

fixture `localhost`
    .page('http://localhost:8000');

test
    .requestHooks(logger_localhost)
    ('logs calls to localhost', async t => {
      await t.expect(logger_localhost.contains(record => record.response.statusCode === 200)).ok(); // green
});

我如何成功拦截对Google Analytics（分析）的呼叫？

1 个答案:

答案 0 :(得分：3)

正如马里昂（Marion）所说，这可能是由于时机原因。以下代码有效：

import { Selector, RequestLogger } from 'testcafe';

const gaCollect = 'https://www.google-analytics.com/collect';

const gaLogger = RequestLogger({gaCollect}, {
  logRequestHeaders:     true,
  logRequestBody:        true,
});


fixture `Fixture`
    .page('http://localhost:8000')
    .requestHooks(gaLogger);

test('Log Google Analytics call', async t => {
    await t.click('#ga-button')

    await t.expect(gaLogger.contains(record =>
      record.request.url.match(/ec=my_event_category&ea=my_event_action&el=my_event_label/))).ok();

    for(let r of gaLogger.requests) {
      console.log("*** logger url: ", r.request.url);
    }

});

提到的时间因素@Marion似乎起了作用。将前一个代码与以下代码段及其输出进行比较。在这里，我们看不到已记录到https://google-analytics.com/collect的呼叫。

fixture `Fixture`
    .page('http://localhost:8000')
    .requestHooks(gaLogger);

test('Log Google Analytics call', async t => {
    await t.click('#ga-button')

    for(let r of gaLogger.requests) {
      console.log("*** logger url: ", r.request.url);
    }

    await t.expect(gaLogger.contains(record =>
      record.request.url.match(/ec=my_event_category&ea=my_event_action&el=my_event_label/))).ok();
});
