// policy_browsertests.cc contains lots of tests for multiple policies. However,

// here, please put new ones with the policy implementation. For example, a
// network policy test can be moved to chrome/browser/net.
//
// Policy component dependency is not necessary for policy test. Most of

// to enable policy during test.
//
// Simple policy to prefs mapping can be tested with
// chrome/test/data/policy/pref_mapping/[PolicyName].json. If the conversion is
// complicated and requires custom policy handler, we recommend to test the
