Not clear what |type| is. From the implementation it should be something like
"google.com/"
I think you need to tweak the implementation so that every decent string
"mydomain" would result in a valid return TemplateURLData.

Changed type to provider_name. I think parameter is used more like name than
domain.

What do you propose to tweak? I don't see errors in its implementation.
IMHO, if this function returned non valid TemplateURLData, tests using it would
fail.

+
+// Checks that the two TemplateURLs are similar. Does not check the id, the
+// date_created or the last_modified time.  Neither pointer should be NULL.
+void ExpectSimilar(const TemplateURLData* expected,
+                   const TemplateURLData* actual);
+
+// Build default dearch policy for TemplateUrlData object.

Fixed

+void BuildDefaultSearchPolicy(const TemplateURLData& data,
+                              policy::PolicyMap* policy);

In what files do you use those functions? If it's just one then I'd move the
implementation there.

[Alexander Yashkin, 2016/12/05 18:16:48]

Deleted this function.
