Dynamic URL Replacement
As a QA Engineer, you may need to run test cases on different environments (e.g., staging, production) without altering your test scripts. With Dynamic URL Replacement you can execute the same test cases across multiple environments without modifying the test scripts, ensuring seamless execution across different environments.
This feature is applicable only for Web Tests
Prerequisites
You must have created a test run for KaneAI Generated Tests.
How to Use Dynamic URL Replacement
Step 1: Navigate to the Test Runs Page
- Log in to LambdaTest.
- Go to the Test Manager > Test Runs section.
- Click on your desired Test Run.
- Click on Run with HyperExecute button.

Step 2: Configure the Test Execution URL
- In the Run on HyperExecute side drawer, locate the new field labeled Replace Test Execution URL.
- Enter the Pattern URL (your original URL used in the tests) and Replacement URL (URL of different environment you want to test) in the text field.
You can add multiple URLs for all web tests in the run to execute in different environments
Step 3: Execute the Test Run
- If the Replace Test Execution URL field is filled, the entered URL will override the default (Pattern) URL during execution.
- If left empty, the test will run with the default URL.
- Click on the Execute button

Example cURL Command
Here’s an example cURL command to trigger a test run with Dynamic URL Replacement:
curl --location 'https://test-manager-api.lambdatest.com/api/atm/v1/hyperexecute' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic <Base64Auth>' \
--data '{
"test_run_id": "YOUR_TEST_RUN_ID",
"concurrency": 1,
"title": "UNIQUE_BUILD_NAME",
"region": "eastus",
"replaced_url": [
{
"pattern_url": "lambdatest",
"replacement_url": "ajio"
},
{
"pattern_url": "d",
"replacement_url": "flipkart"
},
{
"pattern_url": "hello",
"replacement_url": "1234"
}
],
"accessibility": false
}'
- Replace
<Base64Auth>
with your actual Base64-encoded authorization credentials. - Ensure that the
pattern_url
matches the exact URL pattern used in your test scripts. - Multiple
replaced_url
entries can be added to replace different URLs dynamically.
