If the assert fails because of a comparison, it is useful that the test suite log contains a comparison of these values. unittest.assertEqual() and friends do that for us. * HACKING: Add a section about Python tests. * tests/sanity/style.test: Forbid the use of "assert" in Python tests. * tests/python/298.py, tests/python/341.py, tests/python/471.py, tests/python/accparse2.py, tests/python/aiger.py, tests/python/aliases.py, tests/python/alternating.py, tests/python/bdddict.py, tests/python/bdditer.py, tests/python/bugdet.py, tests/python/complement_semidet.py, tests/python/declenv.py, tests/python/decompose_scc.py, tests/python/det.py, tests/python/dualize.py, tests/python/ecfalse.py, tests/python/except.py, tests/python/game.py, tests/python/gen.py, tests/python/genem.py, tests/python/implies.py, tests/python/intrun.py, tests/python/kripke.py, tests/python/langmap.py, tests/python/ltl2tgba.py, tests/python/ltlf.py, tests/python/ltlparse.py, tests/python/ltlsimple.py, tests/python/mealy.py, tests/python/merge.py, tests/python/mergedge.py, tests/python/misc-ec.py, tests/python/optionmap.py, tests/python/origstate.py, tests/python/otfcrash.py, tests/python/parity.py, tests/python/parsetgba.py, tests/python/pdegen.py, tests/python/prodexpt.py, tests/python/randgen.py, tests/python/relabel.py, tests/python/remfin.py, tests/python/removeap.py, tests/python/rs_like.py, tests/python/satmin.py, tests/python/sbacc.py, tests/python/sccfilter.py, tests/python/sccinfo.py, tests/python/sccsplit.py, tests/python/semidet.py, tests/python/setacc.py, tests/python/setxor.py, tests/python/simplacc.py, tests/python/simstate.py, tests/python/sonf.py, tests/python/split.py, tests/python/streett_totgba.py, tests/python/streett_totgba2.py, tests/python/stutter.py, tests/python/sum.py, tests/python/synthesis.py, tests/python/toparity.py, tests/python/toweak.py, tests/python/tra2tba.py, tests/python/trival.py, tests/python/twagraph.py, tests/python/zlktree.py: Replace all occurrences of "assert" by calls to unittest.TestCase methods.
