If I understand you correctly, this'll do the trick:

irb(main):024:0* s=3D"Iam testung the aplication"
=3D> "Iam testung the aplication"
irb(main):025:0> s[/\btest\w*/]||s[/\w*/]
=3D> "testung"
irb(main):026:0> s=3D"Iam running the aplication"
=3D> "Iam running the aplication"
irb(main):027:0> s[/\btest\w*/]||s[/\w*/]
=3D> "Iam"
