Hey BuildKite Team, I’m using the Test Engine Runs API to get failed executions - [Runs API | Buildkite Documentation](https://buildkite.com/docs/apis/rest-api/test-engine/runs#get-failed-execution-data). I can see that these executions match what I see in the buildkite UI when I look at the same run ID. However, I really want to know the failed test count. There doesn’t seem to be an API to get the failed test count. And I can’t seem to get the same number if I dedupe test execution by location or test ID. Could you please let me know what the easiest way to fetch failed test count would be? ---

Hey @jonathanyeong 👋 , At the moment there isn’t a single API field that returns “failed test count” for a run. The usual approach is to compute it from executions. To match the UI-style numbers, you generally want to ignore `skipped` and count unique failing tests, which you can do as `count(distinct test_id)` across the failed executions for that run. If you are seeing a mismatch, one common cause is the failed-executions endpoint result cap/pagination, so make sure you are retrieving all failed executions before deduping. Can you tell me more about what you have in mind re: failed tests? Do you mean **unique tests that failed at least once** (count distinct test\_id), or **total failed executions including retries** (count failed executions)? ---

Thanks for the reply! Got it. I’m counting unique failed tests and it looks like I’m getting more failed test count than what’s shown in the UI. Which is strange. I want to know the number of unique tests that failed at least once. I don’t care about retries. Seems like the only way right now is to manipulate the failed executions result. Thanks! ---
