I don't think this is OK. See EmbeddedWorkerTestHelper and co.

Ah, that's a nifty helper class. Updated.

+
+  BackgroundFetchDataManager* GetDataManager() const {
+    return background_fetch_data_manager_.get();
+  }
+
+ private:
+  TestBrowserThreadBundle browser_thread_bundle_;
+
+  std::unique_ptr<TestBrowserContext> browser_context_;

[Peter Beverloo, 2017/02/13 18:35:06]

nit: no need to use an std::unique_ptr<>, just have a TestBrowserContext as a
member

[harkness, 2017/02/14 13:52:46]

Done.

+  std::unique_ptr<BackgroundFetchDataManager> background_fetch_data_manager_;

+TEST_F(BackgroundFetchDataManagerTest, AddRequest) {
