A Test metric is a standard means of measuring some attribute of the software testing process. They establish test progress against the test schedule and may be an indicator of future results. Metrics are produced in two forms – base and derived metrics.
Examples of base metrics:
# New test cases
# Regression test cases
# Test cases run
# Test cases not run
# Passes
# Fails
# Test cases under investigation
# Test cases blocked
Examples of derived metrics:
% Test cases complete
% Test cases passed
% Test cases failed
% Test cases blocked
% Test defects corrected
HiMetrics can be prepared at any level of SDLCRequirements:-> Schedule Variance-> Effort Variance-> Frequency of CR's, etcTesting:-> Test cases count per module-> Test cases types: ...

1) Test the upgrade itself. Do problems arise? Has anything new been introduced that needs to be accounted for? If so, make sure it works properly.
2) Run functional tests that rely on the database to ensure they function properly.
3) Run performance tests to ensure data is obtained within specified performance parameters.
4) Ensure data integrity is maintained after upgrade. Contstraints, for example, should still be handled as expected.
5) Run load and/or stress test to ensure the upgraded database still handles user load and performs well under the most business-critical resource-intensive circumstances.
6) Test the Oracle client. Ideally, any issues will have been caught in the upgrade test, but it is a necessary step in the process.
1. Identify and execute the testcases which can exercise all the database operations from application.
2. Execute automation scripts
3. Execute performance tests
4. Identify and execute testcases which update the existing records to test the backward compatibilty.

Recovery testing is the forced failure of an application to determine whether it can recover without impaired functionality or data loss. The breadth and depth of recovery testing depends on the mission-critical nature of the application.
Some examples are:
1) Take a database down while an application is sending transactions and then bring the database back up again. Verify there is no loss of data and that the application resumes in a way that users will know how to proceed.
2) While an application is running, restart the computer and validate there is no data loss and that users can proceed without negative side effects.
3) While application is receiving data over a network, unplug and reinsert the network cable to validate the application's ability to continue receiving without loss of data.
4) Restart the computer while a browser has a number of sessions running simultaneously and then determine if the browser is able to recover all of them.

The only reasonable answer is D) Users cannot test software effectively.
Users typically test a system during the Beta release of a product. Though companies should not rely only on this type of testing, it is useful in uncovering defects at little cost to the company. Throughout this period, users perform their day-to-day activities and are not thinking about product quality. They rarely if ever scan the user manual looking for situations of interest to test, so the answer is not A). They generally don't dream up situations randomly to visit all of the features of the system, so the answer is also not B). They don't have access to the company's business processes, so the answer is not C).
I still cannot understand why people are willing to waste time in posting already answered questions? Can you please use the search feature in this site and save everyone's time including yours? This does really anger a lot of people FYI
HI
Ans D is correct
They will not have any idea of testing the software

Faults found by users in production are due to:
The best answer is B) poor software and poor testing
A) is true, but not as complete as B)
D) may also be true, but not as complete as B)
E) is obviously false because quality has nothing to do with luck
HI
I feel it's due to poor quality, here the issue may come due to poor sw, but finding the issues is the major responcibility of a tester than dev team, but there that option was not there, so i can to the option B is correct, poor software and poor testing

Concurrency testing is performed when there are two or more scenarios being tested on the same application at the same time. A common form of concurrency testing takes place when two users are logged into the same application and a tester wishes to determine how their activities impact one another. It is commonly employed to test web sessions and state management.
HI
This will be comes under Multi user testing, ie testing the application by more than one user at same time...
The intention is find the behaviour of application when it was using by more than one user, ie to verify the speed, performance, how data base is responding, etc
