This package does come with a test suite, but it requires an external dependency. If you have munit installed and wish to run the test suite, run the following commands: 

meson configure -Dtests=enabled .. &&
ninja test

Now, as the root user: 

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.
