@stuartmorgan Would you have recommendations on how I could write a test for this? |
I think this is probably one of those very rare cases of not being worth the effort to write a test for. I can't see a way to test this without a bunch of refactoring and faking, and it wouldn't even be a very good test when it was done. And this is a tool that will probably never break two-digit numbers of lifetime users. |
@stuartmorgan Gotcha. Could you mark this as test exempt? :) |

LGTM
test-exempt: package-maintainer-facing tool, which isn't worth the significant effort of adding tests for in this case. |

The Pigeon tool hangs on Windows if you don't have the Java formatter on your path. Repro examples: ``` dart ./tool/generate.dart ``` ``` dart ./tool/test.dart -f windows_integration_tests ``` The root cause is that the tool runs sub-processes without consuming their stdout/stderr output. The sub-process blocks if these pipes get full. See: https://api.dart.dev/stable/3.3.0/dart-io/Process-class.html This change is untested. See: flutter#6198 (comment) Needed for flutter#6196 Part of flutter/flutter#144042
