Load Testing Capabilities

As of October 2024, we have introduced load testing capabilities in TestComplete. Since July 2025, we have also added support for script tests.

Learn more about LoadNinja in our documentation.

Thanks to this integration, you can perform UI load tests based on functional tests. Load testing works for both keyword and script tests created on Chrome and Edge browsers. Tests created on Firefox are not currently supported.

You can discover the capabilities of load testing with our 14-day free trial. Learn more here.

1. Log in to your LoadNinja account.

2. Go to Settings in your profile.

3. Open the API Keys tab.

4. Copy the existing key or click Regenerate to get a new one.

1. Go to File → Install Extensions → Load Testing. Enable the Load Testing option.

2. For Keyword Tests, open a new keyword test or an existing one and record steps. For Script Tests, open a new script test or an existing one and write steps.

3. (Script Tests only) You need to enable the script to be run as a load test:

   1. To do this, you must first record a script for load testing. This executes the TestComplete functional test and prepares it for load testing.

   2. Click Record Script for Load Tests:

4. Go to Execution Plan in TestComplete and create a load group.

   NameMapping must be configured and available for the LoadNinja integration to work properly. Make sure that all objects and elements involved in the integration are correctly mapped in the NameMapping file.

5. Adjust the load configuration settings in the load group.

6. After you've created the load group, add the desired keyword or script tests (that you want to run as a load test) to this group. Right-click on the selected keyword or script test and select the "Add to Load Group" option. You can also drag the test onto the created load group.
