Me and my team member are working on same repository. Someone create a branch from master called test_01, worked on that and commit, push to test_01 and merge to master. In the meantime some commit are done in master. Now I want to checkout that test_01 so that I write
 git checkout test_01 
and got a git error : pathspec 'test_01' did not match any file know to git .
