Side by side
Mockito vs NUnit
Both stand on unit testing frameworks. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Pick Mockito for Java unit tests that need stubbing, interaction checks, spies, or injected mocks. Its free MIT-licensed distribution and build-system setup suit development teams. Look elsewhere if your environment cannot use Java 11, or if Android testing cannot meet the Android P requirement.

NUnit offers a free, MIT-licensed testing framework for several .NET languages, with dependency and repeat controls in version 5. Developers can use its project templates or command-line setup and connect test runs to documented CI workflows.
