1. What is a test case?
“A set of test data and their expected results.
2. Why we write test cases?
To validate the testing coverage of the application.
3. How to write test cases (Example of test case or Sample of Test Case)?
There is no particular formula for writing the test case. Basic elements used in the test case are:
a. Test case number: 1 OR 1.1
b. Test Case Name: Login Verification
c. Test case Inputs or Steps or Action: Enter Login credentials, Click on “login” button.
d. Test Case Expected result: Verify that user is successfully login to “Home” page.
e. Test Case Status: Pass or Fail.
f.
Comments: If test case is fail the you can write why it is failed. Also
you can write bug number here which you are going to be reporting.
You
should ask your self a question before writing the test case "What
should be the steps followed by different users to use this
functionality". Surely you will get the answer and just you have to
write that answer in the form of points in excel sheet. Those points
will automatically become test cases :)
Writing
effective test cases is a skill and that can be achieved by some
experience and in-depth study of the application on which test cases are
being written.
There are levels in which test cases should be analized/designed to avoid duplication efforts.
Level 1: In this level tester should write the basic test cases from the available specification documentation.
Level 2: This is the practical stage in which writing test cases depend on actual functional and system flow of the application.
Level 3: This is the stage in which tester should group some test cases and write a test procedure. Test procedure is nothing but a group of small test cases.
5. Automation vs Manual Test Cases
The following types of test cases can be preferred for automation:
a. Test cases that need to run on every build.
b. Test cases that use multiple data values for same action.
c. Identical test cases that need to be executed using different browsers.
The following types of test cases should not consider for automation testing:
a. Test Cases that will only be executed once.
b. Test Cases used for Ad-hoc/random Testing.
c. Test Cases that are infrequently selected for execution.
d. Test Cases that will require manual intervention i.e. a task not possible to automate.
e. Based on the intuition and knowledge of application. Eg. if you find that you cannot escape from manual intervention.
