Testcontainer Cloud Updates

Filter dashboards by container image names

Ever wondered if you have tests that rely on old container images? Need to check that you're not accidentally using latest in your tests? Curious what other teams are testing with?

You can now filter the dashboards by container image name! By selecting one or more images, your dashboards will show the associated volume of testing activity over time, the number of containers run by image, and the latest test sessions that included these images.

Filter dashboards with unique session or worker id

You can now filter the dashboards by any id found in the logs. When debugging a specific test run or CI job, you often want to see only the corresponding session in the dashboard. You can now copy any unique id, including the session's id or even a given worker's id (sometimes also referred as a "lease" in logs). By pasting this id in the "filter sessions" bar, you will not only locate the session, but also tailor the activity and container widgets to get immediate answers.
