Test Prioritization on Class Level

"# TestPrioritization on Class Level" Steps by steps how to use the tool. Sample run on project common-dbutils:

0. Download the project common-dbutils: https://drive.google.com/file/d/0B2CUmN6iobxCNG5qcWZPSmV0NkU/view?usp=sharing Download and unzip the TestPrioritization Run mvn install to create a jar file. Record the location to the jar file
1. Create a pomTest.xml file. Add the following lines to the Surefire plugin section:

-javaagent:"Your-own-location-of-jar-file/code-coverage-1.0-SNAPSHOT.jar" listener edu.utdallas.JUnitExecutionListener And to dependencies section: edu.utdallas code-coverage 1.0-SNAPSHOT test

2. Create pomBug.xml file. Same as pomTest.xml but delete the ArgLine section

3. Create some random bugs. Here, we modified org.apache.commons.dbutils.BeanProcessor on line 59 protected static final int PROPERTY_NOT_FOUND = -1; to protected static final int PROPERTY_NOT_FOUND = 1;

4. mvn test -f pomBug.xml To run the test in default order with recorded time for bug

5. Fix the bug. Then run: mvn test -f pomTest.xml To collect the coverage statements of tests and rank them based on total and additional strategies

6. Re-create the bug

7. mvn -Dtest=TestTotal test -f pomBug.xml To run the test set in order sorted by Total strategy, and record time to discover bugs

8. mvn -Dtest=TestAdditional test -f pomBug.xml To run the test set in order sorted by Total strategy, and record time to discover bugs
