bug life cycle:


1. New: When the bug is posted for the first time, its state
will be “NEW”. This means that the bug is not yet approved.
2. Open: After a tester has posted a bug, the lead of the
tester approves that the bug is genuine and he changes the
state as “OPEN”.
3. Assign: Once the lead changes the state as “OPEN”, he
assigns the bug to corresponding developer or developer
team. The state of the bug now is changed to “ASSIGN”.
4. Test: Once the developer fixes the bug, he has to assign
the bug to the testing team for next round of testing.
Before he releases the software with bug fixed, he changes
the state of bug to “TEST”. It specifies that the bug has
been fixed and is released to testing team.
5. Deferred: The bug, changed to deferred state means the
bug is expected to be fixed in next releases. The reasons
for changing the bug to this state have many factors. Some
of them are priority of the bug may be low, lack of time for
the release or the bug may not have major effect on the
software.
6. Rejected: If the developer feels that the bug is not
genuine, he rejects the bug. Then the state of the bug is
changed to “REJECTED”.
7. Duplicate: If the bug is repeated twice or the two bugs
mention the same concept of the bug, then one bug status is
changed to “DUPLICATE”.
8. Verified: Once the bug is fixed and the status is changed
to “TEST”, the tester tests the bug. If the bug is not
present in the software, he approves that the bug is fixed
and changes the status to “VERIFIED”.
9. Reopened: If the bug still exists even after the bug is
fixed by the developer, the tester changes the status to
“REOPENED”. The bug traverses the life cycle once again.
10. Closed: Once the bug is fixed, it is tested by the
tester. If the tester feels that the bug no longer exists in
the software, he changes the status of the bug to “CLOSED”.
This state means that the bug is fixed, tested and approved.

What is integration testing and regression testing ?What is
verification and validation ?
Integration testing :
The integration Testing is doing for integrated modules
with the intension of finding interface errors.
Here we have to check whether the integrated modules are
Working properly or not. This can be do through the
integration test cases.

For example: Creating a user account and login to the
system
are two modules.

Here u can see the Create User is a module and Login user
is another module. So First we create a user then with the
new username and password we logon to the system. If it is
working as per the expectation then the test is pass.

we can follow the two approaches in Integration Testing-
Bottom up Integration and Top Down Integration....
regression testing :Test the newversion of the application
with previous version of same application.
After fixing the bug the developer send application to
tester.tester test the application .new functionality of
application have n't create any problem on prevoius
appliction
