Fail fast mode in Launchable CLI

Onboarding new teams and workspaces to Smart Tests (prev. Launchable) is easier now. Some misconfigurations in the CLI setup are only discovered late into workspace setup. This leads to guesswork and confusion into why the CLI is failing even.

Now, every new workspace automatically starts in fail-fast mode. This feature makes the CLI automatically validate its configuration from the very first run. If it detects an issue in the integration, it provides immediate feedback to fix the config issue on the spot.

This will avoid repeated back and forth and provide a seamless integration experience for new teams onboarding the product.

Historical data import for model training

The PTS model needs time to learn and index on your test run data. This "cold start" period can delay seeing the full power of predictive test selection, especially if you are an onboarding team looking to see value immediately.

You can now import your existing historical test data to pre-train the model. By using the new --timestamp flag when recording builds and tests, you ensure your past results are accurately reflected, no matter when you import them. Please read our CLI reference documentation to see how to use the option.

Jump-start your model and get actionable insights almost immediately. This allows you to experience the full benefits of intelligent test selection right from the start, making your evaluation faster and more effective.

Support for new test frameworks - XCTest, Vitest profiles

We have extended support to 2 more test frameworks. See their attached documentation to read how to subset and record tests in the Launchable CLI.

• XCTest: CLI reference

• Vitest: CLI reference

Have any questions or want to try these in your workspace? Reach out to us on smart-test-support@cloudbees.com, we’d love to walkthrough and demo these features with your team.
