Wht is the Difference between Test Harness and Test Driver
Anybody can explain it..Thanks in advance...

Answer Posted / s. rajarathnam

Test Harness:

To generate Test Data by combination, for to test the
Application under regression testing. For Ex if there are 5
Fields in the Customer Enquiry First Name, Last Name,
Address1, Address2 and city, here if you have only 5 set of
original data, with the help of Test Harness Technique we
can generate upto 5X5X5X5X5 = 3125 Test Data can be
generated in that 5 Test data are positive Testdata and
3120 Testdata are negative testdata

Test Driver:

Test Driver is one of the Frame Work For testing the
Application in Automation. Test Driver Consist of 4
Component 1. Spread Sheet, 2. Script Folder, 3. Object
Repository Folder, 4. Main Script.

The Generic Script file should be saved in the Script
Folder and the Appropriate Object Repository File should be
saved in the Object Repository Folder.

In Spread Sheet, it should contains sino, Scenario Name,
Script Path, Object Repository Path, Flag.
in the Script Path Column we have to enter the Correct Path
of the Script and in the Object Repository Path Column we
have to enter the correct path of the object repository.

Flag Column contains the Yes or No (i.e) to execute or not
execute the script.

In the Main Script we are going to import the Spread Sheet
and we are going to get the value of the Flag. if the flag
value is "Yes" then we load the object repository file in
the object Repository and execute the script File. If the
Flag Value is No Control will navigate into the next line.
If there are 20 scenarios then control will to all the 20
lines and execute the script depending upon the flag value.

Scenario A year ago we developed a standards compliant website for a client. Their site is very popular resulting in the client wanting to be able to track how it is being used by their users. The first part of this project is to create a Login function so that users can be identified on the website. The data supplied by users would have to be handled securely. You have been allocated this project to work on. You will be responsible for the task from start to finish and will be expected to give feedback to your manager. User expectations  The client wants their users to be able to login using a page that fits in with the website design.  Tom wants to access the website but doesn’t want his login information to be available to anyone else.  Paul doesn’t want to login to the website because he’s not a frequent user. Task Please provide some feedback on how you would do the following:-  Being the only Test Engineer on this task, what would your approach be for this requirement?  Identify the key areas for testing this page.  What tools if any, would you use to perform the testing, bearing in mind that the testing will be done without using an ‘automated test tool’.  Provide a sample test case that could be used for testing this page, for example as a word or Excel document.
