You can do it with a regular expression. Here is an example:

irb(main):001:0> s = "i am testing the app"
=> "i am testing the app"
irb(main):004:0> s[/\btest\w*/]
=> "testing"

\b --> word boundary
\w --> word character

or use scan:

irb(main):005:0> s="iam testung the aplication"
=> "iam testung the aplication"
irb(main):006:0> s.scan /\btest\w*/
=> ["testung"]

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

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