Functional Testing occurs out to be the core of all testing domains. The primary objective that occurs is that the name itself indicates a quality assurance of the software through a functional point of view. What you see/view over the screen, you require to “test” it. It can be Java API or it could be a net web service. You require to validate what the interface occurs out to be supposed to provide you. Specifically, often, you would not be informed regarding the business requirements, & yet you occur to be expected to come up with a good “tested” software product.
There occur several steps that are required before a “functional “test can get completed. First of all, before beginning any testing that you have come up with a “test plan”. Test plan is similar to a formal document that consists of the steps & procedures that are undertaken through the Software Testing team so as to fully test the project. Once the plan gets approved the team proceeds out with the test route. & it always starts with functional or manual testing. All of the requirements must be understood before you can start testing, & that is really necessary. Since we gain experience within this industry so we can easily find that various projects that get budgeted are failed to expect the response in their business just because of this reason. If there occurs confusion/lack of understanding related to the business requirements then the business flow is not properly understood & leads to problematic issues. Since you expect your business flow to be tested before delivering to the end-user. The requirements occur out to be subject to change & they must be managed with the help of a project manager.
Once the requirements get fulfilled (it is an outgoing process), the testing team begins with their test scenarios a process through which the test scenarios get identified & noted down. It is quite pertinent to mention that one requirement or business case occurs to be the point to one or more than one scenario.
It is almost a kind of requirement for the scenarios that there occurs an input (or more than one) & an output (at least one). Once the scenarios get finalized, the testing team can proceed with the test case part.Once the test cases get written down in the document form(they get written in MS word document)or it gets entered in a test tracking tool like Mercury’s Test Director or JIRA), the result out in defects or suggestions/improvements.
These defects occur out to prioritize & work upon & eventually, it leads to regression testing, where the test engineer holds the re-test of the defects again so as to verify the fixes.
Multiple tools have been developed for the functional test, however, automated tools cannot guarantee that the functional testing occurs to be accurate & complete. The major challenge that the developers face occurs out to be what is tested or what is not tested. Along with this, the time taken for functional testing occurs to be critical, wherein the developers are necessarily required to meet delivery commitments. Along with the automated tools, it is quite necessary for functional testing to get supported through a well-defined practice & get the integration through the software development process. These factors are overlooked that results in an unfavorable income. It is necessary to be consistent in functional test practices so that the software satisfies testing objectives.
An effective functional examination ensures software developers to determine whether the functional requirements get implemented in the code. The testing team occurs out to be able to translate functional requirements into executable test cases that confirm the level to which the code satisfies the requirements at any point in time during the software development life-cycle. It eliminates out the requirement for countless rewrites that results through missing or incorrect functionality.
