Guided Unit Test Generation

Overview

This is a guided unit test generation tool for Java programs based on JavaParser

Structure

You can find the value pool initialization process in src/main/java/edu/illinois/cs/test/generator/PoolInit.java file

You can find the test generation process in src/main/java/edu/illinois/cs/test/generator/TestGenerator.java file

How to run the tool

Please find the Application.java file in src/main/java/edu/illinois/cs/test

Run the Application.java file

Attention: remember to change the address of the target folder you want to generate its tests

If you want to see the code coverage report by Clover, please check the Clover branch. To check the coverage report, use the following command:

$ mvn clean clover:setup test clover:aggregate clover:clover

The report is the index.html under the target/site/clover directory.

PoolInit pool = new PoolInit("target class address (e.g. src/main/java/edu/illinois/cs/test/)");
TestGenerator tg = new TestGenerator("target class address (e.g. src/main/java/edu/illinois/cs/test/)");

Attention: You can also modify this function to target a specific class

public void MethodTraverse(String target) {
        Path sourcePath = Paths.get(target);
        SourceRoot sourceRoot = new SourceRoot(sourcePath);

        try {
            Files.walk(sourcePath)
                    .filter(path -> path.toString().endsWith(".java"))
                    .forEach(path -> {
                        try {
                            CompilationUnit cu = parse(path.toFile());
                            visit(cu, null);
                        } catch (FileNotFoundException e) {
                            e.printStackTrace();
                        }
                    });
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

For instance, if you want to generate tests for Entities class, you can change ".java" to the filename of the class

The tool mainly focuses on Jsoup project, so it may have some other undesired bugs when you try to run it on other projects
