cmd/internal/test2json: generate and validate test artifacts

2026-03-09T18:02:12Z

Adds a mechanism for generating test2json test artifacts from and validating them against a real test. If a .test file has a corresponding .src file, TestGolden will now treat the .src file as a script test, executing it and verifying that the output matches the contents of the .test file. Running TestGolden with the -update flag will also regenerate .test files if they have a corresponding .src file. Capturing the output of the script test in this way required making minor changes to cmd/internal/script/scripttest. This was motivated by CL 601535 (golang/go#62728). Specifically, testing that CL required adding src/cmd/internal/test2json/testdata/frameescape.test which has a multitude of non-printing characters and thus must be generated by executing `go test`. Using a script test to generate the test file is more reliable than doing it by hand.
