Test parameters generation
Default values are auto generated for the tested methods parameters. Currently, this behaviour is not configurable. Groovy tests generators are more robust in a sense that map constructors can be used (when applicable) to initialize objects with setters inline. This is not supported yet for Java test generators, since assignment to local variables for initialization of test parameters complicates the test generation template. Personally, I would always recommend preferring Groovy over Java when it comes to unit testing. If you haven’t transitioned yet to Groovy as your test code language of choice - now is a good time start :)
Tip: Generated test method call line can get very long depending on the depth level of nested objects passed to the tested method. Set the max line limit in IntelliJ Code Style configuration:
Code Style ->
Groovy -> set
Right margin (columns) and check
Ensure right margin is not exceeded.
Please note these settings will effect not just the test code generation. Currently its not possible to control the max line length for generated test code only.
TestMe motto and current shortcomings
TestMe IJ Plugin aims at generating as much Unit Test boilerplate as possible. The project still lacks some maturity level. You can further read about those dilemmas in this blog post
