| """Tweaked TargetSubject for asserting on a cc_binary target. |
| |
| Adds a `binary_extension` to the meta info that can be used in format strings that then |
| match both Windows and non-Windows targets. |
| |
| Offers the same interface as TargetSubject, in fact it is just a TargetSubject, with additional |
| meta info. |
| |
| Example use: |
| |
| cc_binary_target_subject.from_target(env, target).executable().short_path_equals( |
| "{package}/{name}{binary_extension}" |
| ) |
