Verify browser is opened by windows application

Product Forums Katalon Studio

I’m testing a windows application (WPF). The app has a button that opens a web browser and navigates to a specific Url. I’m having a hard time verifying that the web browser is opened and the has navigated to the correct url. Katalon doesn’t seem to recognize the web browser. I’ve tried a few options:

  1. com.kms.katalon.core.configuration.RunConfiguration.storeDriver
  2. driver.switchTo().window(winHandle)
  3. WebDriver driver = DriverFactory.getWebDriver()

None of the option seem to work. Since there is no webdriver created. Is there a way to assign a webdriver to the web browser opened by the windows application?

Did this resolved in Katalon? I’m in the same situation now

I’m not sure if any of the below will work, but you can try to see if something good happens. If one of them works, then comment out all further statements unless you want to check them out as well, so you have options on how to do your task.

import com.kms.katalon.core.model.FailureHandling as FailureHandling
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

try {
    "move focus to the browser"
    WebUI.switchToWindowIndex('0')
} catch (Exception) {WebUI.comment("index 0 did not work") }

try {
    "move focus to the browser"
    WebUI.switchToWindowIndex('1')
} catch (Exception) {WebUI.comment("index 1 did not work") }

try {
    "Switch to main page"
    WebUI.switchToDefaultContent()
} catch (Exception) {WebUI.comment("default did not work") }

try {
    gSiteURL = "https://.."
    WebUI.navigateToUrl(gSiteURL)
} catch (Exception) {WebUI.comment("navigate to url did not work") }

WebUI.maximizeWindow()

WebUI.verifyTextPresent("your text here", false, FailureHandling.STOP_ON_FAILURE)

WebUI.closeBrowser()

Problem to solve

There was a post in the Katalo Forum:

Let me quote the full post:

Solution

I made a search and found the following StackOverflow thread:

Especially the post by Ashmed Ashour at Nov 23, 2021 looked promissing to me.

I tried to interprete his idea into a set of code in Katalon Studio, and got succeded.

Description

Environment

  • macOS Sonoma 14.7.2
  • Katalon Studio Free v9.0.1

Launching Chrome with --remote-debugging-port opened

I made a bash shell script <projectDir>/open_chrome_with_remotedebuggingport

open -a "Google Chrome.app" --args --remote-debugging-port=9222 --user-data-dir=$HOME/tmp/temporary-chrome-profile

Please note that both of --remote-debugging-port and --user-data-dir are required.
You need to create the folder as the --user-data-dir before you start Chrome.

I did the following to make the shell script executable:

$ chmod +x open_chrome_with_remotedebuggingport

When I run this shell script, I could see Chrome browser opened. It should have the debugger listening to the port #9222.

Test Case script that connects to the Chrome externally opened

I made Test Cases/interactWithAnExistingzBrowserSession

import org.openqa.selenium.WebDriver
import org.openqa.selenium.chrome.ChromeDriver
import org.openqa.selenium.chrome.ChromeOptions

import com.kms.katalon.core.webui.driver.DriverFactory
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

System.setProperty("webdriver.chrome.driver", DriverFactory.getChromeDriverPath());
ChromeOptions options = new ChromeOptions()
options.setExperimentalOption("debuggerAddress", "127.0.0.1:9222")
WebDriver driver = new ChromeDriver(options)
DriverFactory.changeWebDriver(driver)

WebUI.navigateToUrl("https://www.youtube.com/")

String title = WebUI.getWindowTitle()
assert title.contains("YouTube")

This script will launch a WebDriver which tries to connect to the Chrome at the IP address 127.0.0.1 with port #9222.

With the Chrome has been already opened by the above script, I ran the test case. The test case ran OK. The test case sucessfully verified that the Chrome is displaying YouTube.

Conclusion

What does mdu_kay7 need to do?

mdu_kay7 has to change his Windows app. The app must start Chrome with --remote-debugging-port=9222 and --user-data-dir as my shell script does. Without the port is opened by Chrome process, external processes like Katalon’s test case script will never be able to communiate with the Chrome process.
