Software Testing is one of the most important aspects of IT industry. It is very important that developed software has to be tested, to make sure that the software is working fine and made as per the requirements and standards. The prime goal of software testing is that the software should give the desired results according to the business requirements and should be free from bugs. Software testing broadly classified into two parts – one is manual testing and another is automation testing. Manual testing is a testing in which we executing the test cases manually without any tool support. It is actually an oldest way of testing and around 60% of all testing carried out today is manual.
Its an initial process of every software activities and a developer has to perform manual test operations without any sort of automated assistance. This make manual process is a cumbersome activity, as it requires several stages such as: Unit Integration, System and User Acceptance Testing and such process needs certain set of qualities; patient, observant, speculative, creative and innovative skills. Manual testing can be replaced by automation testing. Taking tool support and executing the test cases by using automation tool is known as automation testing.
In fact, automation is usual done when same process is required repeatedly. Manual process is time consuming and takes lot of time and cost than automated to write and run. Such process requires lot of skills and test the quality of developers as it provides limited visibility. Compare to manual process automated may require less complex setup and tear down.
Automated testing can actually enforce and driven clean design decisions Manual testing required huge investment in human resources because alltest cases need to be executed manually so more testers are required in manual testing but in Automation testing there is less investment in human resources because all test cases are executed by using automation tool so less tester are required in automation testing.
Also manual testing is less reliable as tests, a tester may not be performed with precision each time because of human errors while Automation tests perform precisely same operation each time they are run. Software testing cannot guarantee against software problem or failure, but it can minimize the risk of faults developing once the software in use. Software is being used in all verticals of the industry like banking, retail and manufacturing. The accuracy of the Automation comes from Accuracy of the software being used. The more quality the software is, the more quality the testing. Software Testing is the Key to achieve a Quality Software.
