Minor nit - you should test manifest.scope as well.

+  const GURL kUrlWithPort("http://www.google.com:42");
+
+  content::Manifest manifest = GetValidManifest();
+  manifest.start_url = kUrlWithPort;
+  EXPECT_FALSE(AreWebManifestUrlsWebApkCompatible(manifest));
+
+  manifest = GetValidManifest();
+  manifest.icons[0].src = kUrlWithPort;
+  EXPECT_FALSE(AreWebManifestUrlsWebApkCompatible(manifest));
+}
