A developer is responsible to unit test their code.
Developers are usually paid more than testers and they are
usually looked upon with more favor by management. With
this in mind, developers don't have time to test. They
bring in the money by writing applications. Also, here is
an example.
a Basic accounting system. You have General Ledger (GL),
Accounts Payable (AP), Accounts Receivable (AR). A
developer may be coding the AR portion or the AP porition.
That portion may work great. But when you combine the GL,
AR, and AP portions, that is when there is a better chance
for defects. Again, a developer does not have the time to
test. if they did, a company would not need to hire a team
of software testers.
And a more simple reason would be, A developer has written
the code, they have unit tested it, they believe it is
correct and therefore to them it doesn't need any more
testing.
When you look at something too much, you tend to have
tunnel vision.

Developer only developed the software and he knows each
flows of his codes and logics, some times lack of time or
mood they may ignore the some mistakes and also due to dead
lines they may not find such errors and also they will be
confident on their code, so considering all these developer
if he tests his own software also he will be thinking that
his code is still working fine.

Answer / biju
Because anybody who creates something would have an
emotional relationship to his creation, In this case a
developer would have an emotional relationship with the code
as he has written the code and would never like/want any one
(including him) to find bugs in his code.
