+
+use shirabe::util::platform::Platform;
+
+/// PHPUnit loads `bootstrap.php` once for the entire test run (see `composer/phpunit.xml.dist`'s
+/// `bootstrap` attribute), so every PHP test implicitly gets `COMPOSER_TESTS_ARE_RUNNING=1`
+/// before it runs. Without it, `Application::do_run` disables interactivity whenever stdin isn't
+/// a tty (as it isn't under `cargo test`), so interactive `ApplicationTester` runs silently no-op
+/// instead of consuming `set_inputs`.
+///
+/// TODO(phase-d): this is only wired into `get_application_tester()` (used by the `command` test
+/// binary) rather than into every test binary's `main.rs`, unlike PHPUnit's bootstrap which
+/// covers the whole suite unconditionally. Call this from a shared entry point across all test
+/// binaries once one exists.
