Define custom ID for test-suite

On every test-suite upload, a new value for test_url is generated. You need to use this value to execute your Espresso tests with the latest build of your Espresso test-suite.

If you want to use a constant value to specify the test-suite and don’t want to modify your scripts after every build upload, you can define a custom ID for your test-suite. Use the same custom ID every time you upload a new build of the test-suite. Here is an example cURL request to upload an Espresso test-suite with the custom ID defined as CalculatorAppTest :

curl -u "YOUR_USERNAME:YOUR_ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/test-suite" \
-F "url=https://www.browserstack.com/app-automate/sample-apps/android/CalculatorTest.apk" \
-F "custom_id=CalculatorAppTest"

A sample response to the above API request is shown below :

 {
    "test_url":"bs://f7c874f21852ba57957a3fdc33f47514288c4ba4", 
    "custom_id":"CalculatorAppTest",
    "shareable_id":"exampleuser/CalculatorAppTest"
 }

While executing your Espresso tests, simply use the custom_id value (CalculatorAppTest in the above example) to specify the Espresso test-suite. The test execution will pick the last uploaded build corresponding to that custom ID.
