Branch outcome in the above could also be decision outcome.
Branch Testing is a structural or white box
technique, because it is conducted with reference to the code. A decision is an executable statement that may transfer control to another statement.
In an ideal world every branch of every component would be fully tested. However, in the real world this hardly ever happens.
In branch/decision testing every possible branch is tested, regardless of the outcome. Compare this to Statement testing, where if there is no statement on the branch, it is not tested.
