Mobile testing with Katalon: a learning path from recording to reporting

Tips and Tricks
1

If you’re starting mobile testing with Katalon, this is a short path through the whole flow: author a test, run it, and read the results. Most links go to Katalon Academy video lessons, so you can watch and follow along, not just read.

The path uses four products: Katalon Studio, Katalon Runtime Engine (KRE), Katalon Test Cloud, and Katalon TestOps.

Tip: let AI do the first pass. Katalon AI Assistant can write a test script from a plain-language prompt, turn a recording into a test that checks real behavior, and explain a failure you didn’t write. Steps marked (AI) below show where it helps. A good place to start is the AI Assistant course on Katalon Academy (1h 10m).

Step 1: Author your tests in Studio

Record a real user journey in your app once, such as sign-in or checkout. Then use AI to turn the recording into a test that verifies the result, not one that only repeats the taps.

Step 2: Run your tests with KRE or Test Cloud

KRE and Test Cloud run the same tests. There’s no fixed order. Pick the one that fits what the test needs. If you’re not sure, read Katalon’s guide to choosing between them.

Choose KRE if you need on-premise control, run in air-gapped or security-restricted environments, or want to run tests from CI/CD.

Choose Test Cloud if you want no setup, real device coverage, and the ability to scale up quickly.

    4 short lessons: move off local machines, schedule recurring runs, test on real mobile devices, and debug live on a real device.

Step 3: Analyze and share results in TestOps

Every run from KRE or Test Cloud ends up in TestOps. Look at it as a trend your team can act on, not only a pass or fail count.

Great path, thanks @nghi.phan . A few things that tend to matter once you’re past Step 1:

  1. Prefer accessibility id or resource-id over XPath for mobile objects, and use explicit waits (Mobile.waitForElementPresent) rather than fixed delays. Most “flaky” mobile tests come from timing, not logic.
  2. Decide the app state per test (fresh install vs keep data) with the noReset/fullReset desired capabilities, otherwise one test’s login or data leaks into the next.
  3. In Step 2, running from the command line is headless, but mobile tests still need a reachable device or emulator on the agent. That setup effort is worth weighing when you choose between KRE and Test Cloud.
  4. In TestOps, compare results by device and OS version so device-specific failures stand out.

It might help beginners to add a short “device setup / Appium prerequisites” step before Step 1.

Device setup / prerequisites (I feel should be added before before Step 1)

  1. Check your Studio version and OS. Android works on Windows, macOS and Linux. iOS testing needs a Mac with Xcode installed.
  2. Android: install the Android SDK (platform-tools) and set ANDROID_HOME. Run adb devices, and your device or emulator should show as “device”, not “unauthorized”.
  3. Real Android device: enable Developer options and USB debugging, and accept the RSA prompt on the phone. An emulator works too (create an AVD in Android Studio).
  4. iOS: install Xcode and its command line tools, and set up signing for WebDriverAgent (needed for real devices). The simulator is the easiest way to start.
  5. Appium: Studio ships with a built-in Appium, so you usually don’t need to install it separately. Only point Studio to your own Appium if you want a specific version.
  6. Before recording: confirm the device appears in Studio’s device list, and know the path to your .apk/.ipa for Mobile.startApplication.
  7. Quick sanity check: launch your app from a one-line test case first, then start recording.
