本文介绍了如何在 Testcafe 中记录 Google Analytics 调用?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试自动测试跟踪代码，我正在使用
但是，这些测试是绿色的
import { RequestLogger } from 'testcafe';const logger = RequestLogger('http://example.com');夹具`示例`.page('http://example.com');测试.requestHooks(记录器)('记录对 example.com 的调用', async t => {等待 t.expect(logger.contains(record =>record.response.statusCode === 200)).ok();//绿色});const logger_localhost = RequestLogger('http://localhost:8000');夹具`localhost`.page('http://localhost:8000');测试.requestHooks(logger_localhost)('记录对本地主机的调用', async t => {等待 t.expect(logger_localhost.contains(record =>record.response.statusCode === 200)).ok();//绿色});如何成功拦截对 Google Analytics 的调用?
解决方案
正如 Marion 所说，这可能是由于时间问题.以下代码有效:
import { Selector, RequestLogger } from 'testcafe';常量 gaCollect = 'https://www.google-analytics.com/collect';常量 gaLogger = RequestLogger({gaCollect}, {logRequestHeaders:真，日志请求体:真，});夹具`夹具`.page('http://localhost:8000').requestHooks(gaLogger);test('记录谷歌分析调用', async t => {等待 t.click('#ga-button')等待 t.expect(gaLogger.contains(record =>record.request.url.match(/ec=my_event_category&ea=my_event_action&el=my_event_label/))).ok();for(让 gaLogger.requests 的 r) {console.log("*** 记录器 url:", r.request.url);}});@Marion 提到的时间因素似乎起了作用.将前一个与以下代码段及其输出进行比较.在这里，我们没有看到记录到
I am trying to automatically test tracking code and I am using the RequestLogger from Testcafé. I succeeded to intercept calls to example.com and localhost but not to https://www.google-analytics.com/. What could be the reason?
Expected
This test should be green
Test code
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();
});
Fixture for this test
I am serving the following index.html page via python -m SimpleHTTPServer 8000
<!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>
Observed
The above test is red
However, these tests are green
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
});
How can I intercept calls to Google Analytics successfully?
解决方案
As Marion suggested it is probably due to timing. The following code works:
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);
}
});
The timing factor @Marion mentioned seems to play a role. Compare the previous with the following snippet and its output. Here, we do not see the calls logged to https://google-analytics.com/collect.
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();
});
