The result, for many teams, is a repository that has grown faster than anyone can maintain it: The same login flow gets written three times. A regression suite gets copied for a release and never merged back. The cost shows up later: slower runs, fixes that miss two of the three copies, and coverage numbers that claim more than the team tests. Past a few thousand cases, nobody finds them manually.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Please try againThe Test Deduplication Agent reads test cases the way a reviewer would. It analyses each case’s title, steps, and description and matches on meaning rather than wording, so cases that describe the same behaviour in different words are caught, not just exact copies. Every match gets a score from 0 to 100, grouped into bands, so teams clear near-certain duplicates first and work down to cases that overlap in intent but diverge in wording.Nothing is deleted automatically. Each duplicate is reviewed side by side against a base test case, with an AI-written summary of how the two relate. Reviewers can ignore a match, promote a better-written duplicate to become the base, or mark it for deletion. A running tally shows what has been marked, broken down by confidence band, and the final deletion requires explicit confirmation. Test runs and their results are retained.This advertisement has not loaded yet, but your article continues below.“AI has removed the friction from writing tests, and that has quietly created a new kind of debt inside test repositories,” said Mudit Singh, Co-Founder and Head of Growth at TestMu AI. “Duplicates don’t look like a problem until a suite takes twice as long to run and a fix lands in one copy but not the other three. We built the Test Deduplication Agent to understand what a test case is actually checking, surface the overlap with a score, and then get out of the way so a person makes the final call.”The agent clears duplication that already exists; keeping new duplicates out is handled at the point of creation by Smart Context, which checks the existing repository before AI generates any test case. Three further Test Manager capabilities round out repository upkeep:Archive test cases: Retire a test case without destroying it. Archived cases drop out of lists, runs, reports, and duplicate scans but keep their ID, version history, and past results, and can be restored unchanged. Up to 500 can be archived in one action. Read moreShare test cases across projects: Maintain a test case once in a source project and share it, with the same ID, to other projects instead of copying it. Every change reaches every receiving project; each project runs it and keeps its own results. Read moreBulk test run actions: Move, copy, or delete up to 1,000 test runs in one action. Moved runs keep their ID, URL, and history; copies start fresh for the next regression pass.
