Test Automation Framework

Test automation framework is a set of assumptions, concepts and tools that provide support for automated software testing. The main advantage of such a framework is its low cost for maintenance. If there is a change in any test case, only then the test case file needs to be updated while the Driver Script and Startup script will remain the same. There's no need to update the scripts in case of any changes to the application. Choosing right framework/scripting technique helps in maintaining the costs. Costs associated with test scripting are due to the development effort and the maintenance efforts. The approach of scripting used during test automation also has an effect on the costs. Various framework/scripting techniques that are generally used:

• Linear (procedural code, possibly generated by tools like those that use record and playback)
• Structured (uses control structures - typically ‘if-else’, ‘switch’, ‘for’, ‘while’ conditions/ statements)
• Data-driven (data is persisted outside of tests in a database, spreadsheet, or other mechanism)
• Keyword-driven
• Hybrid (two or more of the patterns above are used)
  • 1. defining the format in which to express expectations
    2. creating a mechanism to hook into or drive the application under test
    3. executing the tests
    4. reporting results
