Finally, you”ll be told to type – make test_prog, and Parrot will successfully build the test interpreter. Now you should run some tests; so type ”make test” and you should see a readout like the following: perl t/harness t/op/basic…..ok,1/2 skipped:label constants unimplemented in assembler t/op/string….ok, 1/4 skipped: I”m unable to write it!
