PATH environment variable
Follow the steps to build Tint with CMake, but include the additional
-DTINT_EMIT_COVERAGE=1 CMake flag.
<tint>/tools/tint-generate-coverage script to run the tint executable or unit tests and generate the coverage information.
The script takes the executable to invoke as the first command line argument, followed by additional arguments to pass to the executable.
For example, to see the code coverage for all unit tests, run:
<tint>/tools/tint-generate-coverage <build>/tint_unittests --gtest_brief
The script will emit two files at the root of the tint directory:
coverage.summary - A text file giving a coverage summary for all Tint source files.
lcov.info - A binary coverage file that can be consumed with the VSCode Coverage Gutters extension.
