@2010Qn. 1Potential problems and disadvantages of introducing an automated testing toolAutomated testing tools has always easened the work of testing, with lots of advantages to the organization, however it has some setbacks that may make an organization choose the manual testing over it, some of the demerits include the fact that it demands proficiency to be able to create and maintain it, run it and also to customize the scripts according to the requirements of the test. It also has problems with maintenance where it requires high maintenance from the experts.
Incase of large automation suite then the maintenance cost will be very high. Automation errors are a major setback here since if they go undetected, they will give false testing, also considering that they are always hard to detect, and they may only be detected after the damage to the test has been done, mostly through the launching and falling over of the software. Every management often need a cost effective method of testing, automated testing has proved so expensive due to the licensed tools for testing, expartriates involved, maintainance cost of play-back, as well as the initial cost for starting the test.
Other problems include training of the staff on using the technology, much time needed for its implementation, susceptibility to damage, slow test throughput, need for debugging, sensitivity of GUI which may lead to replacement of scripts, inability to gauge the usability of materials, lack of human insight as well as its probability of producing results that are conflicting (Dustin, 2000). In undertaking the automated test, the following steps are necessary Plan stepThis is the most crucial step since the changes are geared to bring better output results.
The goals and targets have to be determined, various methods of achieving the goals are compared to get the best results, then the revision or designing of the components is done for better outcomes, finally, education, and training is then considered. Expected output has to be the primary focus while accuracy is paramount. The Do, Check and Act steps include: The Do, Check and Act processes are employed after the planning has been done, they involveDo: the next step from planning is implementing the automated test plan on a small -scale in order to gauge the performance.
Check: After this the results are compared with the expected results to see if any small difference exists. The checking is carried out to prove whether the new idea is actually working. it is also useful in the study of the processes that were selected, this information is then taken to other decision makers for further approval. Act: the differences have to be critically analyzed for the establishment of their causes since they come from a step or more steps of the P-D-C-A cycle.
Where to use changes resulting in improvement should be determined. Incase the four stages don’t crate the need for improvement then the scope for application of the steps should be refined until the plan involving improvement is attained. Finally, with satisfactory result, the automated testing findings can be used for further developments (Fewster, 1999 ).
