Test Automation / Device Cloud
Mocha and Mockito both target the test automation space, and on paper their pricing, lock-in and ratings land close together. The useful split is positioning: Mocha is pitched at legacy node codebases with established mocha+chai+sinon stacks, while Mockito is pitched at java teams doing any real unit testing on non-trivial codebases. Beyond the headline, Mocha carries high lock-in (free oss js test framework) and free and open-source; Mockito carries high lock-in (free oss java mocking) and free and open-source. Mocha is a fit when you are legacy node codebases with established mocha+chai+sinon stacks. Mockito is a fit when you are java teams doing any real unit testing on non-trivial codebases. The honest trade-off: Mocha is explicitly not for new projects where vitest offers the same power with far less config; Mockito is explicitly not for kotlin-first teams who will be happier with mockk. On the product side, Mocha is described as Feature-rich JavaScript test framework running on Node.

Choose Mocha if you are legacy node codebases with established mocha+chai+sinon stacks and comfortable with its free and open-source.
Not for: New projects where Vitest offers the same power with far less config
Choose Mockito if you are java teams doing any real unit testing on non-trivial codebases and comfortable with its free and open-source.
Not for: Kotlin-first teams who will be happier with MockK
Check each tool's dedicated page for deeper reviews, setup notes, and pros/cons.
Both tools use free pricing. Mocha is listed as free and open-source; Mockito as free and open-source. Without specific volume and seat assumptions it is not possible to say which is cheaper in general.
Migration from Mocha is harder: Mocha is rated high lock-in (free oss js test framework). You can still move, but expect schema-mapping, export tooling and a longer cutover window. Budget engineering time accordingly.
Both tools tie at 5/5 for developer experience on our scoring. The real difference will show up in your specific workflow, not the headline rating. A one-hour spike on both is the fastest way to decide.
Mockito is pitched at java teams doing any real unit testing on non-trivial codebases, which overlaps with Mocha's fit (legacy node codebases with established mocha+chai+sinon stacks) but is not identical. Note that Mockito is explicitly not for kotlin-first teams who will be happier with mockk, so it only replaces Mocha if you are outside that exclusion. Feature-for-feature parity is not guaranteed, so confirm the specific capability you rely on before switching.
