To Error is Human is the simple fact which drives the need to have for automation testing. Mainly because, handbook testers may possibly not execute the exam conditions correctly. There will be large amount of prospects for producing blunders. They might give wrong enter info thanks to typo, or they may well not detect the true behavior of the process properly, or they could not report the take a look at result effectively, or they could miss out on to execute some test scenarios, or they may forget to operate some preconditions, or they could change the sequence of check case execution in scenario sequence is vital.
One more critical component is, Automation examination scripts will be used as a way of storing area/venture/task Awareness gained by the Take a look at Engineers. Say for case in point, if a Tester will work in task for a person yr, he might have used a lot more time for studying the domain, objective of the challenge, modules in the task, circulation of all functionalities. He will be acquainted with identified challenges and troubles.
If this Tester leaves from the venture, the expertise gained by him also will leave.
It is really difficult for the newly joining Tester to realize all the things from the Take a look at Circumstance document.
If automation test scripts are presently offered then the new Tester can just start off the tests by jogging the automation scripts, with out attaining considerably knowledge about the challenge.
He can comprehend the movement/information by viewing the execution of the automation examination scripts. But in any case, he should really obtain venture/domain understanding to improve/update the automation scripts further. So we can say that test automation is a way of storing awareness.
Automation tool this sort of as QTP (Swift Test Specialist) has characteristic for storing screenshot of each individual and every single web page navigated during the execution. So it can be utilised as a proof for completion of tests, and also we can refer the screenshots of preceding executions if there is any need to refer them.
Check report can be quickly penned to a tailored report web site which will be certain accuracy of the report and also it can make improvements to glimpse & truly feel of the report.
The really critical edge of automation tests above handbook screening is, execution speed. Examination execution can be completed speedily and also we can execution the scripts in night time time also without the need of human involvement. So eventually overall time required for tests can be decreased which will drastically enable for well timed venture completion. There may perhaps be requirement of accomplishing some tests at specific time. It can be easily accomplished by placing execution of people automation examination scripts in a process scheduler/crone career. The instrument this kind of as QTP supports automation object product to accomplish this.
The practical take a look at automation scripts will be valuable for doing effectiveness tests also. Since quite a few general performance take a look at equipment will assistance reusing/calling of these take a look at scripts.
Some sort of tests requires comparing huge amount of data between previous edition and existing edition as component of regression tests. Almost it could not possible for accomplishing it manually. This trouble can be quickly solved by very simple shell script or any other scripts these types of as vbs, wsh.
As the automation examination equipment help Information Pushed Screening, Take a look at execution can be done repeatedly with quite a few diverse data sets.
There are whole lot of automation check tools offered for performing Purposeful, Regression and Performance Screening. Test full, SilkTest,SilkPerformer, QARun, QALoad, TestPartner, WinRunner, LoadRunner, QTP, Rational Robotic and openSTA are some of them. QTP is most greatly used now as it supports vbscript and it can be applied for screening a lot of distinctive applications just by incorporating necessary include-ins.
