Manual testing VS Automation testing and the benefits of QTP

What is Manual testing?
Manual testing is the oldest and most rigorous testing method. Manual testing requires a tester to perform manual test operations to find defects in a software or application. The tester ensures that’s the software meets its requirements by writing, understanding and executing test plans and test cases.
Pros
  • If the test case only runs twice a coding milestone, it most likely should be a manual test.
  • Less cost than automating
  • It allows the tester to perform more ad-hoc (random testing). In my experiences, more bugs are found via ad-hoc than via automation.
  • The more time a tester spends playing with the feature, the greater the odds of finding real user bugs.
Cons
  • Running tests manually can be very time consuming
  • Each time there is a new build, the tester must rerun all required tests – which after a while would become very mundane and tiresome.
What is Automation testing?
Over the years automation testing has gained a lot of focus in the product development world as it is more time effective and also more strategic in improving the quality of a software or product. Automation testing is the process in which a manual test is automated by using specific testing tools. A popular automated testing tool is, Quick Test Professional (QTP).
Pros
  • If you have to run a set of tests repeatedly, automation is a huge win for you.
  • It gives you the ability to run automation against code that frequently changes to catch regressions in a timely manner.
  • It gives you the ability to run automation in mainstream scenarios to catch regressions in a timely manner.
  • Aids in testing a large test matrix (different languages on different OS platforms). Automated tests can be run at the same time on
  • Different machines, whereas the manual tests would have to be run sequentially.
Cons
  • It costs more to automate. Writing the test cases and writing or configuring the automate framework you’re using costs more initially than running the test manually.
  • Can’t automate visual references, for example, if you can’t tell the font color via code or the automation tool, it is a manual test.
Regression Test cases and Automation Testing
Regression testing can be specific to a module of a project OR for complete project (full regression testing).
Let’s assume we have 500 test cases to test in Amazon.com.  Choose important test cases
which covers the major functionality of the project. Test case that covers all the necessary
components, modules and related to the defect fixes should include. It may also include
testing the performance of the application. It also depends on project dead lines.
If we have automation test scripts, we can perform regression testing on all 500 test cases.In agile methodology, builds are deployed daily, weekly basis. Automation test scripts can
be executed daily/weekly on every new build.
How automation is done:
Record the script
Enhance the script by adding functions and a data driving
Run the scripts
