Reconstructing Input Parameter Models from Combinatorial Test Suites

Reconstructing Input Parameter Models from Combinatorial Test Suites

Combinatorial interaction testing (CIT) is a black box testing approach which generates a set of (abstract) test cases from a given input parameter model. Existing algorithms try to minimize the number of test cases while preserving a certain coverage of the input parameters. See #1 and #2 for more information.

Usually the input parameter model (IPM) is handcrafted. Afterwards, a combinatorial strategy is selected and the test suites are generated (See #3). However, the creation of the IPMs is complicated and error-prone. Identifying possible parameters and parameter values is a manual and creative task and might lead to invalid or missing combinations.


In this thesis we would like to try the other way round. The goal of this thesis is to reconstruct input parameter models from a given set of (handcrafted) test cases.

Possible Tasks

  • Design an approach to reconstruct input parameter models
  • Develop a prototype tool which (semi-)automatically reconstructs IPMs- Identify possible open source projects and apply your approach and tool to them
