This project provides an automated tool for generating JUnit test suites for Java code, aiming for high branch and line coverage. It is designed for Java developers and teams seeking to improve test suite quality and reduce manual effort, with a proven track record in ANT Group supporting over 1000 projects.

How It Works

The generator is built upon EvoSuite, employing Search-Based Software Testing (SBST) as its core framework. It introduces optimized algorithms to address performance issues with large search spaces (e.g., extensive String usage) and improve efficiency. Additionally, it incorporates an optimal call sequence algorithm for more readable and logical test case structures, and specifically handles Spring Framework dependencies by generating mock statements for autowired fields to prevent NullPointerException.

Quick Start & Requirements

• Install via Maven: mvn clean install -Dmaven.test.skip=true
• Copy generated JAR: cp ${user.home}/.m2/repository/org/smartut/smartut-master/1.1.0/smartut-master-1.1.0.jar smartut.jar
• Project dependencies preparation: mvn clean compile, mvn clean install -Dmaven.test.skip=true, mvn dependency:copy-dependencies
• Setup command: java -jar ./smartut.jar -setup <project_classes_path> <dependency_jars_path>
• Generation commands: java -jar ./smartut.jar -class <fully_qualified_class_name> or java -jar ./smartut.jar -target <classes_folder_path>
• Requires Java Development Kit (JDK) and Apache Maven.
