在Katalon 7中以及与Chrome DevTools Protocol
Integration插件配合使用，如此处所述，您可以拦截网络请求。

以下示例显示了如何在Wikipedia中模拟搜索请求，以便结果始终为“ 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)
