testRTC allows you to set your own customer environment variables in running test scripts via the APIs. This gives more flexibility when executing the commands from CI/CD or other test suite environments.

You can use environment variables to:

1. Decide which URL to use (when launching tests on heroku machines for example)
2. Pick specific room id’s or names in a test
3. Decide on usernames or passwords
4. Etc

Example

Lets assume we want to create a custom variable to pick the room id for the user to join in a test.

We will call it ROOM_ID.

Inside our test script, we can refer to it as process.env.ROOM_ID, and use it in whatever fashion we need. Like:

client.rtcSetAdditionalInfo("process.env.ROOM_ID " + process.env.ROOM_ID);​Code language: JavaScript (javascript)

To populate ROOM_ID with a value, we need to add our environment variable as an array of tuples. Something like this:

"environmentVariables": [
    {
        "variable": "ROOM_ID",
        "value": "room1"
    }
]Code language: JSON / JSON with Comments (json)

Invoking it through cURL would be something like this:

curl -X POST "https://api.testrtc.com/v1/tests/{{TESTID}}/run" -H "accept: application/json" -H "apikey: {{APIKEY}}" -H "Content-Type: application/json" -d "{ \"environmentVariables\": [{ \"variable\": \"ROOM_ID\", \"value\": \"room1\" } ]}"Code language: Bash (bash)
