In Test Automation, Data driven frame work is a most effective frame work which gives more test coverage, with less effort. It becomes necessary for testing an application with different test data even in automation testing. While developing test automation for these types of application, Data-Driven frame work is best to use.

In Test Automation, Data driven frame work is a most effective frame work which gives
more test coverage, with less effort.
It becomes necessary for testing an application with different test data even in automation
testing. While developing test automation for these types of application, Data-Driven frame
work is best to use.
General Approach for creating data driven test:
 Record (or develop) your test scenario with a set of test data in your tool.
 Create data storage (Excel, csv or data base) and in which give multiple values for
each test data.
 Replace the values in the recorded script with proper variables.
 Write script to access a set of test data from the storage, and assign it to those
variables. While executing the test these values will be used.
 Make a loop statement so that the test can be executed for all set of test data.
Testcomplete™ has many in-built features to develop Data- Driven test. Testcomplete™
gives easy access to the data storages like excel, csv, data base etc. Testcomplete™ has
different scripting objects & methods to retrieve data from data storage. Even If we do not
have scripting knowledge, we can use the Data-Driven Loop wizard to create Data-
Driven test.
The following example demonstrates how to create data-driven test with Data-Driven
Loop wizard for a key word test script. Here we are using excel sheet as our data storage.
1) Let us take the following key word test script. This test, logs-in into a login page by
entering user name & password. Then it checks the welcome message is
displayed or not.

2. 2) Now we will create a data driven loop for these two values (username & password)
and execute this test for multiple login details. Let us say we want to execute the
test using the following login details, which are stored in an excel sheet.
3) Now select the UserNameTextbox & PasswordTextbox rows in the keyword test
editor & right click on it. From the menu select ‘Make Data Loop’ option.
4) Now it will open Data-Driven Loop window for inputting Variable name.

3. 5) Now select a Table type. Here we are using the excel sheet as data storage. So
select the Excel Worksheet option and click Next.
6) Browse the source excel file containing Test Data from ‘Open File’ window and click
Next button.

4. 7) Select the sheet name in which the data are stored from list shown .Also ensure that
the ‘Treat first row as column names’ check box is checked. Then click Next
button.
8) In ‘Select Records’ window choose ‘From the beginning’ and ‘To the End’ radio
buttons. These two options are used to execute the test for all the rows in that

5. sheet. If specific records only needs to used, then select record information. Click
Next button.
9) In ‘Update Values’ window assign each columns of excel sheet to each values that
needs to be parameterize. In our example, for UserNameTextbox field select the
User Name column and for PasswordTextbox field select the Password column
of our excel sheet. Then click Finish button.

6. 10) Now the command for Data Driven loop in the Keyword test editor will be seen.
Also username & password values would have been replaced with the corresponding
table variables.

7. 11) Now if this test runs, it will execute the login action multiple times with the data in
that excel sheet & give results
Note that here each row is treated as a set of test data. I.e. test data for a single
execution should be kept in the same row of the excel sheet. For a single execution,
If you want to use data from multiple rows, you cannot use this method.
