| * This is a public type so that the Android test runner can create an instance directly as it |
| * insists upon doing. It then runs the test, which behaves exactly like this package's existing |
| * PackageSanityTests. (The test would run on the JVM, too, if not for the suppression below, and |
| * that would be a problem because it violates small-test rules. Note that we strip the |
| * suppression externally, but it's OK because we don't enforce test-size rules there.) |
| * |
| * We'd just use PackageSanityTests directly, saving us from needing this separate type, but we're |
| * currently skipping MediumTests on Android, and we skip them by not making them present at |
| * runtime at all. I could just make _this_ test a MediumTest, but then it wouldn't run on |
| * Android.... The right long-term fix is probably to get MediumTests running under Android by |
| * default and then suppress them strategically as needed. |
