Thanks, I like this better.  The one problem is that I'm not entirely sure
whether the global vectors will work out, though perhaps static initializers are
fine in tests?  Or if constexpr can be added?

Done. Changed to generate fingerprint dynamically

+  ASSERT_TRUE(
+      web_app_manifest_section_table->AddWebAppManifest(manifest_1.get()));
+
+  // Adds alicepay manifest to the table.
+  mojom::WebAppManifestSectionPtr manifest_2 =
+      mojom::WebAppManifestSection::New();
+  manifest_2->id = "com.alicepay";
+  manifest_2->min_version = static_cast<int64_t>(2);
+  // Adds two finger prints.
+  manifest_2->fingerprints.push_back(kFingerprintTwo);
+  manifest_2->fingerprints.push_back(kFingerprintOne);
+  ASSERT_TRUE(
+      web_app_manifest_section_table->AddWebAppManifest(manifest_2.get()));
+
+  // Verifys bobpay manifest.
+  mojom::WebAppManifestSectionPtr bobpay_manifest = std::move(
+      web_app_manifest_section_table->GetWebAppManifest("com.bobpay"));
+  ASSERT_EQ(bobpay_manifest->id, "com.bobpay");
+  ASSERT_EQ(bobpay_manifest->min_version, 1);
+  ASSERT_EQ(bobpay_manifest->fingerprints.size(), 2U);
+  ASSERT_EQ(bobpay_manifest->fingerprints[0].size(), kFingerprintOne.size());
+  for (size_t i = 0; i < kFingerprintOne.size(); i++) {
+    ASSERT_EQ(bobpay_manifest->fingerprints[0][i], kFingerprintOne[i]);
+  }

[Scott Hess - ex-Googler, 2017/04/11 19:31:46]

ASSERT_TRUE(bobpay_manifest->fingerprints[0] == kFingerprintOne);

should work fine.  Though if static objects are banned in tests, that changes
things.

[gogerald1, 2017/04/11 21:53:30]

Done.

+  ASSERT_EQ(bobpay_manifest->fingerprints[1].size(), kFingerprintTwo.size());
+  for (size_t i = 0; i < kFingerprintTwo.size(); i++) {
+    ASSERT_EQ(bobpay_manifest->fingerprints[1][i], kFingerprintTwo[i]);

+  ASSERT_EQ(alicepay_manifest->min_version, 2);
+  ASSERT_EQ(alicepay_manifest->fingerprints.size(), 2U);
+  ASSERT_EQ(alicepay_manifest->fingerprints[0].size(), kFingerprintTwo.size());
+  for (size_t i = 0; i < kFingerprintTwo.size(); i++) {
+    ASSERT_EQ(alicepay_manifest->fingerprints[0][i], kFingerprintTwo[i]);
+  }
+  ASSERT_EQ(alicepay_manifest->fingerprints[1].size(), kFingerprintOne.size());
+  for (size_t i = 0; i < kFingerprintOne.size(); i++) {
+    ASSERT_EQ(alicepay_manifest->fingerprints[1][i], kFingerprintOne[i]);

+}
+}  // payments
