The biggest practical difference between Pest and Mockito is lock-in. Pest is rated low lock-in (open source php testing framework), while Mockito is rated high lock-in (free oss java mocking). That changes how hard a future migration would be and how much strategy to put into exit planning. Beyond the headline, Pest carries low lock-in (open source php testing framework) and free and open-source; Mockito carries high lock-in (free oss java mocking) and free and open-source. Pest is a fit when you are laravel and modern php teams who want readable, expressive test syntax. Mockito is a fit when you are java teams doing any real unit testing on non-trivial codebases. The honest trade-off: Pest is explicitly not for legacy php codebases deeply coupled to phpunit's xunit style; Mockito is explicitly not for kotlin-first teams who will be happier with mockk. On the product side, Pest is described as Elegant PHP testing framework with expressive it()/test() syntax built on top of PHPUnit, adding architecture tests, mutation testing and browser testing via Playwright, and Mockito is described as Most popular mocking.
Quick take

Choose Pest if minimizing lock-in matters and you accept its stated trade-offs for laravel and modern php teams who want readable, expressive test syntax.
Not for: Legacy PHP codebases deeply coupled to PHPUnit's xUnit style
Choose Mockito if you accept higher lock-in in exchange for its specific capabilities and you are java teams doing any real unit testing on non-trivial codebases.
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. Pest 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 paths between Pest and Mockito depend on the specific data and integrations. Neither vendor publishes a ready import tool for the other. Expect a custom export-transform-import exercise.
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 Pest's fit (laravel and modern php teams who want readable, expressive test syntax) but is not identical. Note that Mockito is explicitly not for kotlin-first teams who will be happier with mockk, so it only replaces Pest if you are outside that exclusion. The lock-in profile differs (low vs high), which is the main thing to weigh.
