Try it in a small test task inside your agent workflow.
EvoSuite is a tool that automatically creates test cases for Java programs. It uses a smart search method to find test inputs that cover as much of the code as possible. The generated tests are then cleaned up and include checks that capture the current behavior of the code.
EvoSuite is a research tool that automatically generates JUnit test suites for Java classes. It targets code coverage criteria such as branch coverage and uses an evolutionary approach based on a genetic algorithm to derive test suites. The generated unit tests are minimized to improve readability, and regression assertions that capture the current behavior of the tested classes are added. EvoSuite can be used from the command line, via Docker, or as a Maven plugin. It supports Java 8 and Java 11, and offers options for large-scale experiments. The tool is open source under LGPL-3.0 and has been developed by the EvoSuite team at the University of Sheffield and other institutions.
