Automated Software Testing and related Tools

custom software development companies

Software testing is major part of software development life cycle in all the software development companies. There are so many methods for software testing. One method is automated software testing. The objective of automated testing is to simplify testing using minimum scripts. It uses automated software tools to run tests based on predetermined algorithms to compare the developing program’s expected outcome with the actual outcome. If both the outcomes are aligned the program is running properly otherwise there is need for improvement. If two programs are not aligned with each other you have to do changes in the code and test it again until the outcomes align.

Automated testing is best to use when you’re working on a large project, and when there are many system users. Advantages of automated testing, for the custom software development companies, are its relative quickness and effectiveness. You have to set up initial test then it’s an easy process to repeat tests, continuously fill out the same information and everything is done for you automatically.

Many open source automation testing tools are available for almost all types of testing such as functional, Web, UAT, regression, performance etc. There are several criteria’s based on which a custom software development company can select tool for doing automated testing. Those are:-
  • Target Testing Team
  • Application & Platform support
  • Testing Types
  • Programming ability
  • Application Technology
  • Test Data Sources
  • Testing Tools Outputs
  • Technical Support
  • Pricing Policy

Some of the tools that can be used for doing the automated testing are:

1. Silenium

Selenium is the best option for automated testing of Websites today. It is becoming popular and it is the first choice of automation testers as well as custom software development organizations for automating the testing of Web-based applications for both the GUI as well as the functionality. It  can also be used as a unit testing tool for JavaScript. Silenium  is package of various test components.  Selenium has following three modes for executing the test cases and test suites: Record-Playback mode (Selenium IDE)‏, Selenium Remote Control (RC) Mode, Test Runner Mode.

2. Watir

Watir is a set of Ruby libraries for automating web browsers. It  allows to write tests that are easy to read and maintain. It drives browsers the same way people do and also checks results such as whether expected text appears on the page. It is open source.

3. Windmill

Windmill is web application testing tool.  It supports cross-browser test recorder, JavaScript integration and an interactive shell to automate web browsers. It is open source.

4. SoapUI

SoapUI is a tool for automation of web application testing. SoapUI is available as a free open source edition as well as a commercial Pro edition.

5. Tellurium

Tellurium is a web automation tool that allows you to design and write your automated tests using plain English without any scripting or programming experience. It has a full library of “Plain English” commands – plus the ability to create your own – Tellurium’s natural language makes it easy for everyone to read and write advanced automated tests. No programming experience is required.

6. QTP

HP QTP uses Visual Basic Scripting  for automating the applications. Scripting Engine is available as a part of the Windows OS thus it is not installed exclusively.
Thus, for doing automated testing, a custom software development company have to analyse each tool in detail and as per requirement you have to choose best tool which fulfils all the criteria.
