Tricentis SeaLights is a quality intelligence platform. It watches builds and test runs, builds a map of which tests exercise which methods, and uses that map to work out which tests a code change actually puts at risk. Tests that nothing in the change touches are skipped.
Tricentis files SeaLights and LiveCompare in the same portfolio category, and the pairing holds up. Both answer the same question, which is what genuinely needs retesting after a change. LiveCompare reads SAP transports and support packs. SeaLights reads code change sets across Java, .NET, Node.js, Python, Go, and C++. Shared premise, different input, no overlap in footprint.
Scoping only pays off if something downstream acts on it. SeaLights returns a list of tests to exclude and the test runner applies it. Tricentis Tosca and Testim both implement that natively, so a Merito engagement usually ends with SeaLights deciding the scope and Tosca executing what survives.
The first thing SeaLights gives a team is not a saving. It is a measurement. Coverage numbers usually fall once real execution data replaces unit test percentages, and release gates get rebuilt around coverage of changed code rather than an overall figure. The cycle time comes later, once the model has seen enough varied runs to be trusted.
Ideal use cases
- Regression suites long enough that a full run gates the release
- Teams that cannot currently answer which tests cover a given change
- CI compute spend growing faster than the codebase
- Go and no-go decisions that need coverage of changed code rather than overall coverage
- Tosca or Testim suites where a scoped test set can be applied automatically
- Mixed automated and manual inventories that need one coverage picture
