We will try to understand few important aspects with Automated Testing. This document will help you understand what Automated Testing means, why its required and how to implement it using AppPerfect.



What is Automated Testing?

Automated Testing is use of software program to control execution of testing tasks automatically. Automated Testing involves automating manual testing tasks which are mostly time consuming and error prone. Automated Testing is a more accurate, efficient, reliable and cost effective solution to manual testing. Automated Testing involves carrying set of tasks automatically and comparing the result of same with the expected output and ability to repeat same set of tasks multiple times with different data input and same level of accuracy. It also involves setting up of test conditions, test control and test reporting functions.

Manual testing is often error prone and there are chances of most of the test scenarios left out. Also with the project in development phase where source code changes appear every other day, manually keeping up with the pace to test each and every feature is a difficult task. More often then not the newly added features would bring regression along with them, so to accurately cover all the old test cases manually is very time consuming and error prone. Moreover testing with different hardware configurations and operating systems makes job more difficult.

Automated Testing is a solution to all the issues raised with Manual testing. An Automated Testing tool can playback all the recorded set of tasks, compare the results of execution with the expected behavior and report success or failure to the test engineers. Once the automated tests are created they can easily be repeated for multiple number of times with different data sets and can be extended to cover additional features at a later time.

Most of the software organizations consider Automated Testing as critical to their testing process and there are many things which should be considered before selecting an Automated Testing tool. A company can make great strides using Automated Testing. The important benefits include, higher test coverage levels, greater reliability, shorted test cycles, ability to do multi user testing at no extra cost, all resulting in increased levels of confidence in the software.

Following are few key reasons why software organizations choose AppPerfect's Automated Testing solution for its critical testing requirements :

  1. Automated Testing can Run Unattended : With Automated Testing you can run complex and lengthy tests unattended. Test can be scheduled to run overnight and engineers can analyze the results of execution next morning. As a result you save time and improve efficiency and can concentrate on other important tasks while scheduled tests run in background.
  2. Automated Testing provides High Test Coverage : Automated Testing increases the scope of test cases to help improve software quality. Automated Testing can validate and monitor things which is not possible to do manually. It can monitor the machine resources and internal program states to determine if the software is running as expected. Automated tests can easily run hundreds of complex test cases during every test run providing coverage that is impossible with manual tests. Resources freed from repetitive manual tests can utilize the time in creating new automated tests to deal with new features in the application.
  3. Automated Testing can be distributed over multiple machines : Automated Testing allows you to distribute your tests among multiple workstations to simulate real-world conditions while testing web or intranet sites, client-server and other multi-tier applications. Testers can easily manage the list of workstations, specify which automated tests to be run on each workstation and synchronize the automated test execution. Automated test results from all workstations are accumulated into a single report for easier analysis.
  4. Automated Testing with Virtual users simulation : In real world your web applications/services will be accessed online by thousands of users simultaneously. More often applications tested manually are found to be working fine as they only cover single user scenario, but when deployed and accessed by multiple users simultaneously they can fail to perform. Automated Testing can simulate multi user environment using threading model where multiple virtual users can be executed to perform same tasks simultaneously. So you can test all the possible scenarios due to multi-user access before going live. Something which is impossible with Manual testing.
  5. Automated Testing is Cost Effective, Reliable and Efficient: Its practically impossible for a human tester to repetitively cover all the test cases with same amount of accuracy over and over again. Automated Testing's ability to perform complex set of tasks repetitively with same amount of accuracy every time makes it both cost effective and reliable solution for testing.
  6. Automated Testing is Highly Extensible : Once a test case is recorded it can be played back multiple times with different data sets. Its possible to validate output with different data inputs using the same test case by parameterizing the user input. Moreover tests once recorded can be reused and extended to cover more features and test cases as your application grows,
  7. Automated Testing on different hardware configuration : Automated Testing is platform independent. Automated Tests recorded on one platform can be used to played back over different operating systems and hardware configuration.
  8. Automated Testing and Team Sharing : Test Engineers can share the automated test scripts and results with different members in the team. Automated Scripts can be shared with developers which they can use to run after every source change to check for any regression.
