test-unit

To generate unit tests and mocks from source code, provide the code path and optional design documents. The tool analyzes the input to produce test cases and mock objects for service, controller, and mapper layers.

Yes, you can generate JUnit5 test cases with Mockito and AssertJ for large projects. It applies a segmented generation strategy using flags like --class, --method, --layer, --module, and --scenario to handle scale efficiently.

The best way to create test cases for Service, Controller, and Mapper layers is using the --layer segmentation option. This targets the specific module architecture to output structured test templates and mocks.

Generating test cases from source code does not strictly require a design document. You can input just the source code path, but providing a design document enhances test coverage by integrating deeper contextual requirements.

To generate unit tests for a single method, use the --method segmentation option. This isolates the test generation scope to the specific method level, producing focused test cases and targeted mocks.

Using AssertJ and Mockito when generating test cases ensures framework compatibility and fluent assertions. This integration produces complete, runnable test templates that validate complex behaviors and mock dependencies effectively.
