# Shift-Left Testing for Review Events

Lifecycle Center Testing automatically runs assigned test suites when a developer creates a review in DX Inspector, catching issues early before changes advance through the pipeline.

When a developer creates a review in DX Inspector, testing automatically takes over — no manual trigger required. The moment a review is submitted, Lifecycle Center Testing evaluates the work item against the test suites and quality gates assigned to the Development stage, running your configured tests in the background while the review process continues.

This automated checkpoint catches issues early, when the cost of fixing them is lowest. If the test run passes all quality gate requirements, the work item is cleared to move forward. If it fails, the developer is notified with the details they need to investigate and resolve the issue before the change progresses.

## What Happens During a Review Event

- A Test Suite Group Execution is created and runs all test suites assigned to the Development stage.
- Quality gates evaluate the results against your defined standards — pass percentages, severity thresholds, and essential test requirements.
- The work item is marked as passed or failed based on the quality gate outcome.
- If tests fail and automated execution isn't sufficient, developers can run tests manually to meet quality gate requirements before promoting.
- If additional changes are committed while the work item remains In Review, the previous test run is superseded and a new test starts automatically.

Note For automated testing to trigger on review creation, test suites must be assigned to the Development stage and quality gates must be configured. See [Set Up Lifecycle Center Testing](https://help.salesforce.com/s/articleView?id=platform.devops_center_testing_setup.htm&release=264.0.0&type=5 "Configure Lifecycle Center Testing to enforce quality at every stage of your pipeline, from the first review to the final promotion into production.").
