EvoSuite is a Java tool used to automatically generate JUnit test cases.

EvoSuite is a tool that automatically generates test cases with assertions for classes written in Java code. To achieve this, EvoSuite applies a hybrid approach that generates and optimizes whole test suites towards satisfying a coverage criterion. For the produced test suites, EvoSuite suggests possible oracles by adding small and effective sets of assertions that concisely summarize the current behavior; these assertions allow the developer to detect deviations from expected behavior, and to capture the current behavior in order to protect against future defects breaking this behaviour.

The tool is available as a maven, Eclipse, or IntelliJ plugin, from the EvoSuite web site
