name	denigma-test-harness
description	Denigma repository test harness conventions. Use when building Denigma, running Denigma tests, interpreting Denigma test failures, or choosing the correct working directory for the test executable.

Denigma Test Harness

Run the test executable from tests/data, not from the repository root.

The GoogleTest binary expects the current working directory basename to be data and resolves inputs/outputs relative to that directory. Running it from the repository root causes broad false failures such as missing input files, Unknown or misplaced option: --mnx, or assertions from tests/denigmatests.cpp that the cwd is not data.

In tests that read fixtures or write generated outputs, call setupTestDataPaths(); at the start of the test to initialize the fixture and output paths consistently.

Preferred commands:

cmake --build build

../../build/tests/denigma_tests

Run the second command with working directory:

tests/data

ctest --test-dir build may report no registered tests even when build/tests/denigma_tests exists, so run the executable directly unless CTest registration has been verified.
