Testler:

This tool aims at creating a test suite model that can be used to eliminate fine-grained redundancies in Java tests.

In order to create the test model first you need to instrument the project.

Instruction to Build the Test Model

  1. To instrument the project specify the project path in Settings.PROJECT_PATH
  2. run java ca.ubc.salt.model.instrumenter.Instrumenter
  3. You need to run the instrumented project by calling mvn test in the project path
  4. Now you can get the model by calling TestMerger.createModelForTestCases(testCases) and as input provide a list of testcase names that you want to build the model for

Merging Usecase

To merge test cases you can call java ca.ubc.salt.model.merger.TestMerger, it builds a test suite model and uses the test model to identify partly redundant test cases, it then tries to reorganize these test cases in a way that removes the redundancy and repeated production method calls. It writes the reorganized test suite back to the disk. Path for the reorganized test suite can be set in Settings.

Publication

The tool and its empirical evaluation have been published in the following conference paper.
