Right now, as I'm sure you've discovered, we have our own test
framework. While it wouldn't be impossible to change to a different
one, there'll obviously be more work involved in moving all the
existing test cases to use a different framework. The requirements for
Google Test aren't too onerous, by the look of things. However, they
only support C++ tests, so omega would need some careful thought, as
it has both C++ and non-C++ tests.

Although Google Test has some support for sharding tests across
multiple runs, it's limited and you'd have to implement the test
runner that drives it yourself. (There's an explicit FAQ about
parallel test execution.) So I'm not sure how much you'll learn that's
relevant by studying their source code as opposed to working with
Xapian's existing test framework.

Great!
