Rules to execute tests are generated by a simple Python program that integrates into the existing "make check" mechanism. This provides familiarity for developers, and also allows piecewise conversion of the testsuite Makefiles to meson. The generated rules are based on QEMU's existing test harness Makefile and TAP parser.
