Start with `make check` and `tests/test-suite.log`, then trace the `test1` failure and the `test1.expected` versus `testSubDir/test1.test` comparisons named in the output. Reproduce the missing `foo.json` error and verify that `test1`, `test1Formatted_plain`, `test1Formatted_spaced`, and `test1Formatted_pretty` pass.
