/**
 * This UI test looks like it should succeed, but it will actually fail because
 * it triggers a leak.
 *
 * Run this test with:
 *
 * ./gradlew leakcanary-android-sample:connectedCheck
 *
 * Why is this class named "TuPeuxPasTest"?
 *
 * This test fails, intentionally. In French, "Tu peux pas test" could mean "you cannot test"
 * written with poor grammar. Except, that's not what it means.
 * If you're curious, interested in French and have time to waste:
