获取 XHR 响应(网络流量)并在 Katalon Studio 中解析 [英] Get XHR response (network traffic) and parse it in Katalon Studio

问题描述

如何读取 XHR 响应并在 Katalon Studio 中对其进行解析?

How can I read an XHR response and parse it in Katalon Studio?

我目前使用一种解决方法来测试我的应用程序的响应能力:我使用各种 waitForElement_*_()(*=可见、可点击、存在、不可见、不可点击、不可-present) 命令以测量各种元素的加载时间.

I currently use a workaround way of testing responsiveness of my app: I use various waitForElement_*_() (*=visible, clickable, present, not-visible, not-clickable, not-present) commands in order to measure loading time of various elements.

我想更具体地测量网络请求的持续时间(可以在 DevTools - 网络流量中看到).

I would like to get more specific and measure the duration of network requests (that can be seen in DevTools - network traffic).

可以吗?

推荐答案

在 Katalon 7 和 with and with Chrome DevTools 协议集成插件，如 这里可以拦截网络请求.

In Katalon 7 and with and with Chrome DevTools Protocol Integration plugin, as was described here you can intercept network requests.

以下示例展示了如何在 Wikipedia 中模拟搜索请求，以使结果始终为Katalon Studio".

The following example shows how to mock search requests in Wikipedia so that the result will always be "Katalon Studio".

import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.github.kklisura.cdt.protocol.commands.Fetch as Fetch
import com.github.kklisura.cdt.protocol.commands.Page as Page
import com.github.kklisura.cdt.services.ChromeDevToolsService as ChromeDevToolsService
import com.katalon.cdp.CdpUtils as CdpUtils
import com.kms.katalon.core.util.internal.Base64 as Base64
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI
import com.kms.katalon.core.testobject.ConditionType
import com.kms.katalon.core.testobject.TestObject as TestObject

WebUI.openBrowser('')
ChromeDevToolsService cdts = CdpUtils.getService()
Page page = cdts.getPage()
Fetch fetch = cdts.getFetch()
fetch.onRequestPaused({ def requestIntercepted ->
    String interceptionId = requestIntercepted.getRequestId()
    String url = requestIntercepted.getRequest().getUrl()
    boolean isMocked = url.contains('api.php')
    String response = '["Katalon Studio",["Katalon Studio"],["Katalon Studio is an automation testing solution developed by Katalon LLC."],["https://en.wikipedia.org/wiki/Katalon_Studio"]]'
    String rawResponse = Base64.encode(response)
    System.out.printf('%s - %s%s', isMocked ? 'MOCKED' : 'CONTINUE', url, System.lineSeparator())
    if (isMocked) {
        fetch.fulfillRequest(interceptionId, 200, new ArrayList(), rawResponse, null)
    } else {
        fetch.continueRequest(interceptionId)
    }
})

fetch.enable()
page.enable()
WebUI.navigateToUrl('https://en.wikipedia.org/wiki/Main_Page')
TestObject searchInput = new TestObject().addProperty('css', ConditionType.EQUALS, '#searchInput')
TestObject containing = new TestObject().addProperty('xpath', ConditionType.EQUALS, "//div[div[contains(.,'containing...')]]")
WebUI.setText(searchInput, 'Intercept request')
WebUI.waitForElementVisible(containing, 10)
