Just FTR: You don't need the anonymous namespace if you only have constants in
there, as they get internal linkage automatically.

[harkness, 2016/04/12 08:43:35]

Good to know, although if you don't mind, I'll leave it here for now. My next
patch adds a lot to that anonymous namespace.

+
+const char kTestOrigin[] = "https://example.com";
+const char kTestData[] = "1111101111";
+
+}  // namespace
+
+class BackgroundBudgetServiceTest : public ::testing::Test {

[Bernhard Bauer, 2016/04/11 13:58:42]

The initial :: isn't necessary if you are not inside a namespace.

[harkness, 2016/04/12 08:43:35]

Done.

[Bernhard Bauer, 2016/04/11 13:58:42]

That's what |origin| is for, no? :)

[harkness, 2016/04/12 08:43:35]

good point!

+
+  EXPECT_TRUE(budget_string.empty());

[Bernhard Bauer, 2016/04/11 13:58:42]

Nit: If you compare this to an empty string with EXPECT_EQ, you'll get the
actual value in case of a failure.

[harkness, 2016/04/12 08:43:35]

Done.
