Select Unit Test Tools

CASA has not selected a unit test tool for C++ testing. CASA has not selected mock object tools for either C++ or Python testing to help decouple parts of CASA for unit and integration testing.

We plan to keep PyUnit as the recommended CASA Python unit test tool.

Status: See CAS-5601.

Plan

C++ unit test tools

• Collect requirements
• List available open source C++ unit test tools
• Rate by apparent ease of use (based on docs)
• For each of the top three candidates
  • Try trivial examples
  • Verify these work on all supported OSs
  • Try non-trivial examples
  • Verify these work on all supported OSs
• Evaluate candidates for ease of use within CASA
  • Chose one as a candidate for further testing
• Develop trivial example tests on CASA code using candidate tool
  • This includes any changes to CASA build system to run these tests in "make test"
• Develop non-trivial example tests on CASA code using candidate tool
• Document guidelines for using candidate tool
• Present results to CASA developers

C++ mock tools

• Collect requirements
• List available open source C++ mock tools
• Rate by apparent ease of use (based on docs)
• For each of the top three candidates
  • Try trivial examples with C++ unit test tool candidate chosen above
  • Verify these work on all supported OSs
  • Try non-trivial examples with C++ unit test tool candidate chosen above
  • Verify these work on all supported OSs
• Evaluate candidates for ease of use within CASA
  • Chose one as a candidate for further testing
• Develop trivial example tests on CASA code using candidate tool
  • This includes any changes to CASA build system to run these tests in "make test"
