Could you have a NotificationPermissionContextTest class and have
TestBrowserThreadBundle as part of it and TestProfile too? You could expose
TestingProfile via profile()

[Peter Beverloo, 2015/06/29 12:54:21]

I prefer two repetitive lines over introducing a fixture - it's much more
concise. But thank you for the suggestion :-).

+  content::TestBrowserThreadBundle thread_bundle;
+  ContentSetting decided_content_setting;
+  TestingProfile profile;
+
+  GURL requesting_origin("https://example.com");
+  GURL embedding_origin("https://chrome.com");
+  GURL different_origin("https://foobar.com");
+
+  TestNotificationPermissionContext context(&profile);
+  ASSERT_NO_FATAL_FAILURE(
+      context.SimulatePermissionSet(requesting_origin,
+                                    embedding_origin,
+                                    CONTENT_SETTING_ALLOW,
+                                    &decided_content_setting));

[mlamouri (slow - plz ping), 2015/06/29 10:57:42]

Why don't you call directly UpdateContentSetting()?

[Peter Beverloo, 2015/06/29 12:54:21]

Done.

+
+  EXPECT_EQ(CONTENT_SETTING_ALLOW, decided_content_setting);
+
+  EXPECT_EQ(CONTENT_SETTING_ALLOW,
+      context.GetPermissionStatus(requesting_origin, embedding_origin));
+
+  EXPECT_EQ(CONTENT_SETTING_ALLOW,
+      context.GetPermissionStatus(requesting_origin, different_origin));
+}
+
+// Web Notifications do not require a secure origin when requesting permission.
+// See https://crbug.com/404095.
+TEST(NotificationPermissionContextTest, NoSecureOriginRequirement) {
+  content::TestBrowserThreadBundle thread_bundle;
+  TestingProfile profile;
+
+  GURL origin("http://example.com");
+
+  TestNotificationPermissionContext context(&profile);
+  EXPECT_EQ(CONTENT_SETTING_ASK,
+            context.GetPermissionStatus(origin, origin));
+
+  DesktopNotificationProfileUtil::GrantPermission(&profile, origin);

[mlamouri (slow - plz ping), 2015/06/29 10:57:42]

Could you call ::UpdateContentSetting() instead?

[Peter Beverloo, 2015/06/29 12:54:21]

Done.

+
+  EXPECT_EQ(CONTENT_SETTING_ALLOW,
+            context.GetPermissionStatus(origin, origin));
+}
+
+}  // namespace
