Why does this take a char* instead of a Feature?

[Pritam Nikam, 2016/02/09 16:05:54]

base::FeatureList::InitializeFromCommandLine() accepts 2 std::strings as
parameters:|enable_features| & |disable_features| [1].

--enable-features=Feature5,Feature7
--disable-features=Feature1,Feature2,Feature3

As plan was to enable only single feature for tests, I kept it as |char*| i.e. 
Feature.name [2].

Yes, but you could still take a Feature here and extract its name for
InitializeFromCommandLine() here.

Done.

+  scoped_ptr<base::FeatureList> feature_list(new base::FeatureList);
+  feature_list->InitializeFromCommandLine(feature, "");
+  base::FeatureList::SetInstance(std::move(feature_list));
