General Instruction

Solution to Work On

You are working on the solution REPO-ROOT/Test/UnitTest/UnitTest.sln, therefore SOLUTION-ROOT is REPO-ROOT/Test/UnitTest.

Projects for Verification

The REPO-ROOT/Test/UnitTest/VlppReflection/VlppReflection.vcxproj is the unit test project. When any *.h or *.cpp file is changed, unit test is required to run.

When any test case fails, you must fix the issue immediately, even those errors are unrelated to the issue you are working on.

Metadata_Generate and Metadata_Test

These two projects need to run if any reflection code is touched.

To execute these projects, you should:

  • Build the solution with Debug|Win32.
  • Run Metadata_Generate with Debug|Win32.
  • Build the solution with Debug|x64.
  • Run Metadata_Generate with Debug|x64.
  • Run Metadata_Test with Debug|x64.

It generates binary metadata files containing type informations from reflection code.

Metadata_Generate produces Test/UnitTest/Metadata/Reflection{32,64}.bin and Test/UnitTest/Metadata/Reflection{32,64}.txt. Metadata_Test loads the .bin file, regenerates a [2].txt file, and compares it against the .txt baseline to verify binary serialization round-trip correctness.

If the schema of reflected types has changed, the baseline .txt file may no longer match. This is expected. To update the baseline, re-run Metadata_Generate for both Win32 and x64, which overwrites Test/UnitTest/Metadata/Reflection{32,64}.txt with the updated type information. Then re-run Metadata_Test to confirm the round-trip is correct.
