View network and performance data

TestCloud provides built-in tools to help you analyze how your application behaves during automated test runs. You can view:

• App Profiling: Resource usage and performance data for mobile apps.
• Network Logs: API calls and browser network traffic during tests.

To access these logs, you must first enable them using desired capabilities in Katalon Studio.

App profiling

App profiling captures a real-time snapshot of your mobile app performance during test execution. It includes CPU, memory, battery, network, disk I/O usage, as well as frame rate and startup time.

To enable the App profiling data, you need to set the enableAppProfiling desired capability in Katalon Studio.

1. Go to Project Settings > Desired Capabilities and select TestCloud.
2. Add a katalon:options property, set Type as Dictionary, then click the ....
   
3. In the Dictionary Property Builder dialog, add the boolean property enableAppProfiling=true. Click OK to save the settings.

After the test completes:

1. Log in to TestCloud Web App and go to Execution.
2. Select your test run.
3. Click the App Profiling tab for performance metrics.

Metric	Description
CPU Performance/CPU Usage	Shows how quickly the CPU can retrieve and interpret instructions. It shows the average CPU utilization by computations of the app. This functionality detects CPU leaks and over-usage which lead to overheating, battery drains, crashes, and performance issues.
Memory Performance/Memory Usage	Determines the amount of physical memory allocated to the app’s process. It allows you to track and analyze your memory footprint so you can identify potential leaks and inefficient resource usage.
UI Responsiveness	Allows you to quickly assess the app’s health by tracking how long it takes for an app to respond to action and monitoring the delay of the app’s UI responsiveness. Currently, this metric is only available for Android devices.
Disk Usage	Provides insights into how much disk space is being used by both the system and the application during a session.
Network Usage	Provides insights into how your app uses network resources, helping you optimize data transfer and ensure efficient performance.
Temperature	Allows you to monitor battery temperature during app usage, identify features causing excessive heat generation and reduce the risk of device overheating.
Battery Consumed	Monitors how your app impacts battery drain, allows you to identify features that are energy hogs, and optimize them.
Frames per second (FPS)	Real-time measurement of rendering performance throughout the session.
Frame Issues	Visualizes rendering performance of: Jank Frames: Frames taking excessive time to render, causing visual stuttering Frozen Frames: Completely dropped frames that cause noticeable pauses

Network logs

A network log provides detailed browser performance data, including real-time record of all API calls, network requests, and responses exchanged between the application under test (web, mobile, API) and its backend services during an automated test run. It includes request/response headers, bodies, status codes, and timings in the HAR format.

To enable the Network data, you need to set the enableNetwork desired capability in Katalon Studio.

1. Go to Project Settings > Desired Capabilities and select TestCloud.
2. Add a katalon:options property, set Type as Dictionary, then click the ....
3. In the Dictionary Property Builder dialog, add the boolean property enableNetwork=true. Then click OK.

View network log

You can access network logs from the TestCloud Execution monitoring view.

After the test completes, log in to TestCloud Web App and go to Execution. Select your test run and click the Network tab to explore captured requests and responses.

• Use quick filter buttons to narrow down the list by request type: JS, CSS, IMG, MEDIA, DOC.
• Toggle the Errors Only switch to view failed requests, making it easier to detect problems.
• Click Download HAR to export the entire network traffic in HAR format. This is useful for debugging in external tools like Chrome DevTools or HAR viewers.
