some major negative test cases to break the sign up page having username password, email, url addr..

Answer / ramyab.mca@gmail.com

Hai...

The following test cases are major negative testcases for
sign up page:

1) See the limit of username field. I mean the data type of
this field in DB and the field size. Try adding more
characters to this field than the field size limit. See how
application respond to this.

2) Repeat above case for number fields. Insert number
beyond the field storage capacity. This is typically a
boundary test.

3) For username field try adding numbers and special
characters in various combinations. (Characters like !@#$%
^&*()_+}{“:?><,./;’[]). If not allowed specific message
should be displayed to the user.
4) Try above special character combination for all the
input fields on your sign up page having some validations.
Like Email address field, URL field validations etc.

5) Many applications crash for the input field containing ‘
(single quote) and ” (double quote) examples field
like: “Vijay’s web”. Try it in all the input fields one by
one.

6) Try adding only numbers to input fields having
validation to enter only characters and vice versa.

7) If URL validation is there then see different rules for
url validation and add urls not fitting to the rules to
observe the system behavior.
Example urls like: vijay.com/?q=vijay’s!@#$%^&*()_+}{“:?
><,./;’[]web_page
Also add urls containing http:// and https:// while
inserting into url input box.

8 ) If your sign up page is of some steps like step 1 step
2 etc. then try changing parameter values directly into
browser address bar. Many times urls are formatted with
some parameters to maintain proper user steps. Try altering
all those parameters directly without doing anything
actually on the sign up page.

9) Do some monkey testing manually or automating (i.e.
Insert whatever comes in mind or random typing over
keyboard) you will come up with some observations.

10) See if any page is showing JavaScript error either at
the browser left bottom corner or enable the browser
settings to display popup message to any JavaScript error.
