What does seni denemekti mean please?

I know denemek is the infinitive to try, to test.  How does the addition of the "ti" change the meaning?

Tsk ederim

 Looks like a typo?

seni deniyordu: he was testing you

denemekteydi: he was in a trial/test

Or maybe there was something before this?

e.g.

Amaç seni demekti:

The purpose was to test you.

Yes you are correct Dilliduduk.  The first sentence was "Benim amaçım sende para almak değil seni denemekti"

So yes his aim wasn´t to take money from me but he was testing me.

Thank you once again.
