Set Espresso Test Runner

By default, TestingBot will run your Espresso tests with ${packageName}/androidx.test.runner.AndroidJUnitRunner.

If you have defined your own testInstrumentationRunner, you can pass this custom runner during the start Espresso call:

curl -u api_key:api_secret \
-X POST "https://api.testingbot.com/v1/app-automate/espresso/:id/run" \
-d '{ "espressoOptions": { "testRunner": "${packageName}/customTestRunner" }, "capabilities":[{"platform":"ANDROID", "version":12, "deviceName":"Pixel 6", "platformName":"Android"}]}' \
-H "Content-Type: application/json"

Replace the :id with the identifier you received during the app upload call.
