write test 5 negative test cases for pen?

Answer Posted / abdul khader

1. See if the different components (the barrel, cap,
unscrewable head, refill, spring if any etc) of the pen are
fitting perfectly. [Installability Testing!]
2. Test the dimension of the pen. Its shape and size should
be ergonomically designed so as to result in a comfortable
writing experience.
3. Test by writing on a piece of paper. See if you can
write smoothly. It should not be writing and stopping with
breaks! [Usability Testing!]
4.Test the writing capacity (the amount of writing that is
possible from a single refill) of the pen. [Capability/
Reliability Testing!]
5. Test if you can carry the pen in your shirt pocket using
its cap. The cap extension should be firm enough to grip
your pocket! [Robustness Testing!]
6. Test if the ink leaks from the refill under normal
circumstances.
7. Test if the ball of the refill head fits into the socket
with just enough space to move freely.
8. Test if the pen leaks ink if it is carried in a flight.
[Performance Testing!]
9. Test if the pen is usable with different brands of
similar refill. [Compatibility Testing!]
10. Test the pen by writing with different angles of use.
Also test if you are able to write on a vertical surface
[sticky note stuck on a notice board!]
11.Drop the pen from a reasonable height (may be the height
of a study table) and see if it breaks, ceases to write or
continues to work without any damage.
12.test by putting the pen in a “clothes dryer” (ever left
your pen in your shirt pocket before sending it to
laundry!). See if the heat is sufficient to cause a
leakage! [Stress Testing!]
13. Test the ability to write on one sheet of paper on a
hard desk. Look for the quality of writing.
14. Test the pressure needed to be applied to the pen to
have it write cleanly. [Load Testing!]
15. Test if the ink blots the paper (especially in case of
gel pen). [Usability testing!]
