what happens if these tests are running on a device that doesn't actually
support bluetooth?

Isn't this dependent on the type of bots it is being run on?

Good point. I've guarded the unit test with a detection on if the adapter is
present.

+  EXPECT_GT(adapter_->GetAddress().length(), 0u);
+  EXPECT_GT(adapter_->GetName().length(), 0u);
+  EXPECT_TRUE(adapter_->IsPresent());
+  EXPECT_TRUE(adapter_->IsPowered());
+  EXPECT_FALSE(adapter_->IsDiscoverable());
+  EXPECT_FALSE(adapter_->IsDiscovering());
+}
+
+TEST_F(BluetoothAdapterAndroidTest, ConstructNoPermision) {
+  InitWithoutPermission();
   ASSERT_TRUE(adapter_.get());
   EXPECT_FALSE(adapter_->HasBluetoothPermission());
+  EXPECT_EQ(adapter_->GetAddress().length(), 0u);
+  EXPECT_EQ(adapter_->GetName().length(), 0u);
+  EXPECT_FALSE(adapter_->IsPresent());
+  EXPECT_FALSE(adapter_->IsPowered());
+  EXPECT_FALSE(adapter_->IsDiscoverable());
+  EXPECT_FALSE(adapter_->IsDiscovering());
 }
