Try:

        generators.register-standard cxxtest.gencxx-file : CXXTEST_H : CPP(%_runner) ;

that should append the _runner suffix to the generated CPP automatically.

You could have overriden generate-targets to append _runner to the name
of the output target.

Would:

        exe FooTS_runner : FooTS.cpp FooTS.h ;

work, as soon as _runner is automatically appended? Or you want something different?
