This patch adds the Catch [1] unit test framework in version v1.12.2 [2]
along with its integration into the existing build and test definition.
While there is version v2 available, v1 still supports C++98, hence we
can make use of it. The framework is distributed as a single header
file. And since it is less then 500k and it comes with a permissive
license, I decided to directly add the file rather than requiring
users/developers/distributors to satisfy the new dependency.
The integration is fairly simple: A new library libcatch.a provides the
`main` for the tests that run with Catch. The tests themselves require
to include the header as well and to link against said library.
As an example I migrated the test-kmi-whitelist test to Catch. The test
becomes a bit more structured and error reporting significantly
improved. E.g. see this intentional breakage:
| --- a/tests/test-kmi-whitelist.cc
| +++ b/tests/test-kmi-whitelist.cc
| @@ -140,5 +140,5 @@ TEST_CASE("WhitelistWithTwoSections", "[whitelists]")
| suppressions_type suppr
| = gen_suppr_spec_from_kernel_abi_whitelists(abi_whitelist_paths);
| REQUIRE(!suppr.empty());
| - test_suppressions_are_consistent(suppr, "^test_symbol1$|^test_symbol2$");
| + test_suppressions_are_consistent(suppr, "^test_symbol$|^test_symbol2$");
It leads to this test output:
| ---------------------------------------------------------------------------
