# Generating and viewing Tint code-coverage
|
|
|
|
Requirements:
|
|
|
|
* Host running Linux or macOS
|
|
* Clang toolchain on the `PATH` environment variable
|
|
|
|
## Building Tint with coverage generation enabled
|
|
|
|
Follow the steps [to build Tint with CMake](../README.md), but include the additional `-DTINT_EMIT_COVERAGE=1` CMake flag.
|
|
|
|
## Generate coverage information
|
|
|
|
Use the `<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](https://marketplace.visualstudio.com/items?itemName=ryanluker.vscode-coverage-gutters) extension.
