Automated testing vs Manual testing

In developers, QA testing

Software testing is a huge domain, but it can be broadly categorized into two areas. Both manual and automated testing offer benefits and disadvantages. It’s worth knowing the difference, and when to use one or the other for best results.

A Brief Overview of Different Methods:
Automated testing vs Manual testing

Automation is the use of strategies, tools, and artifacts that augment or reduce the need for manual human involvement or interaction in unskilled, repetitive, or redundant tasks.  Automated processes cut back on menial tasks and work that human beings must do.  Testing is just the process of checking and examining different scripts and functionalities to ensure no errors occur. There are two types of testing:  

  1. Manual testing is performed by a human carefully executing the test scripts while sitting in front of a computer.
  2. Automated testing takes the tedious work from humans and is performed meticulously by computers.

Let’s take a closer look at the difference between manual and automated testing.  Manual testing is the process through which software testers and developers run checks manually, comparing program expectations and actual outcomes in order to find software defects.  These manual tests are no more than the tester going through and using the program as an end user would, and then determining whether or not the program acts appropriately.  Manual testing is cheaper in the short-term game and allows for actual human interaction with the process.  It is flexible, but can be tedious and is less realistic for large projects.

Automated testing runs tests quickly and efficiently while allowing everyone to see the results.  Although it can be expensive, the automated test can be reused and repeated again and again.  It offers a fast and high quality approach to testing.  It can also be programmed to do exactly what you need it to do.

A stable environment and app process are a must in automated testing

Certain things are required for Automated testing.  There must be a stable environment and application process.  The regression suite must be fully tested and you must have automatable test cases.  You must also have data on hand to test and you must choose the correct automation tool.  Once it is decided to use an automated test, you must acquire the test tool you’ll use.  You then enter in to the Automated Test Introduction phase before moving in to the Test Planning, Design, and Development phase.  Once you have developed the test, all you have left to do is implement it and assess it!

The top 3 free open source functional testing tools are:

  1. Selenium
    Allows you to perform functional testing for both web application and desktop applications.

  2. Robotium
    Suitable for testing android applications, and it is very easy to use.

  3. Sahi  
    one of the best functional automation testing tools as it provides all the support that is required to automate testing for web applications.

There are a few commercial tools as well.  QTP is the market leader in functional testing tools.  It is a great option for web, Windows, and Mainframe applications.  Test Complete is well used for web-based applications, Android, and IOS.  IBM Rational Test is used for mobile applications, regression testing, integration technologies, and performance testing.
