You first need to decide whether you want to perform object coverage analysis or source coverage analysis (getting familiar with the relevant doc area will help: https://docs.adacore.com/gnatcoverage-docs/html/getting_started.html#general-principles-and-common-notions). From then:
- If you want to do object coverage analysis, you need to select an appropriate coverage criteria (
--level=insnor--level=branch). - If you want to do source coverage analysis, you need to use a consistent coverage criteria (for instance
--level=stmt+mcdcin bothgnatcovinvocations), designate units of interest (see the error message at the end of your logs, and of course the doc can help: https://docs.adacore.com/gnatcoverage-docs/html/units_of_interest.html); also in that case the--routinesoption is useless (it’s valid only for object coverage).
I hope this helps,
Hi, I use gnatcov run --level=stmt+decision ./bin/unit_tests --routines=f to generate trace file and gnatcov coverage --level=stmt+mcdc --annotate=html unit_tests.trace --routines=f for aanalysis report. But I get the following log: bjuci@bjuci-ThinkPad-X270-W10DG:~/github/gtest-demo/build$ gnatcov run --level=stmt+decision ./bin/unit_tests --routines=f warning: Support for coverage of non-instrumented native programs is deprecated and will disappear after GNATcoverage 21 releases. You are encouraged to migrate to instrumentation-based coverage: you can read more about it in our documentation: http://docs.adacore.com/gnatcoverage-docs/html/gnatcov.html Running main() from gtest_main.cc [==========] Running 2 tests from 1 test case.
