Mockito

Mockito is a popular open-source mocking framework for unit tests in Java. It lets developers write clean, readable tests by creating mock objects, stubbing their behavior, verifying interactions, and using simple, fluent APIs to keep test setup minimal and intent obvious.

Mockito publishes 1 API on the APIs.io network. Tagged areas include Java, Mocking, Testing, Unit Testing, and Open-Source.

Mockito’s developer surface includes getting-started guide, release notes, and 8 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/mockito: open an issue to ask a question, or submit a pull request to add artifacts.
