Need for Automated Testing Tools - Testing Tools

As we discussed in the previous chapter, manual testing is time-consuming, error-prone and requires lot of infrastructure and manpower. All these drawbacks can be overcome if the testing process is automated. The testing tools reduce manual testing to a large extent and the testing can be done automatically. Using these tools has many advantages:

  • Once the software is ready for testing, the functionality of the software can be tested repeatedly to improve the quality and reliability.
  • Testing can be done unattended, for example, during nighttime and during holidays.
  • When the software has to be tested in different environments (different hardware platforms, different operating systems, using different browsers etc.), the labor involved can be reduced.
  • Performance testing can be done without the need for many computers and many test engineers. The test tools simulate multiple users on a single machine. As compared to manual testing, finding out transaction response times when multiple users access the same application will be very easy.
  • Testing process can be planned and managed effectively using these tools.
  • Test reports can be generated automatically for later analysis and corrective action.
  • Testing can be done using tools that are available to test not only generic applications such as database applications and web sites, but also for DLLs, Visual Basic Programs, Siebel software, Power Builder software, databases, stand-alone Java applications etc.
  • The testing process can be managed efficiently—the planning can be done systematically, the tests can be scheduled efficiently, and the bug tracking can be done effectively. Hence, using automated test tools results in:
  • Improvement in the quality and reliability of the software. '
  • Drastic reduction in time, effort, and money spent on testing.
  • A systematic approach to the testing process.
  • Efficient management of the testing process even if the teams are at different geographical locations.
