I have seen an umpteen no of posts in every QTP group I visited asking about Test Automation frameworks. Here I would like to collate the useful inputs i received from various QTP groups and discussion forums.

1) Key Word Driven Testing:

The Keyword Driven framework consists of the basic components given below
1. Control File
2. Test Case File
3. Startup Script
4. Driver Script
5. Utility Script

1. Control File a)Consists details of all the Test scenarios to be automated b)User will be able to select a specific scenario to execute based on turning on or off a flag in the Control File c) Control File is in the form of an excel worksheet and contains columns for Scenario ID,Execute (Y/N),Object Repository Path, Test Case File Path

2. Test Case File a)Contains the detailed steps to be carried out for the execution of a test case b) It is also in the form of an excel sheet and contains columns for Keyword, Object Name, Parameter

3. Startup Script a) The Starup script is utilised for the initialization and reads the control files b) It then calls the driver script to execute all the scenarios marked for execution in the control file

4. Driver Script a) It Reads the Test Case files. Checks the keywords and calls the appropriate utility script functions based on specific keyword b) Error Handling is taken care of in the driver script.

5. Utility Scripts a) Perform generic tasks that can be used across applications. It should not be application dependent Advantage of Framework.

  • The main advantage of this framework is the low cost for maintenace. If there is change to any test case then only the Test Case File needs to be updated and the Driver Script and Startup script will remain the same.
  • No need to update the scripts in case of changes to the application.

ALSO

Keyword-driven testing is a Software testing technique that separates much of the programming work from the actual test steps so that the test steps can be developed earlier and can often be maintained with only minor updates, even when the application or testing needs change significantly.

2) Data-driven Testing:

Data-driven testing is a framework where test input and output values are read from data files (datapools, ODBC sources, csv files, Excel files, DAO objects, ADO objects, and such) and are loaded into variables in captured or manually coded scripts. In this framework, variables are used for both input values and output verification values. Navigation through the program, reading of the data files, and logging of test status and information are all coded in the test script.

3) Modularity-driven testing

The test script modularity framework requires the creation of small, independent scripts that represent modules, sections, and functions of the application-under-test. These small scripts are then used in a hierarchical fashion to construct larger tests, realizing a particular test case.
