I. Introduction Functional Testing is basically testing software based on its functional requirements. Meaning it makes sure that the SUT (System Under Test) or program physically works the way it is intended. Now that there is a basic understanding of what Functional Testing is by the definition provided above; How about going more In-depth on the topic. This paper will provide answers to questions that the writer had on the topic as well as to the overall importance of Functional Testing. Questions to be discussed will be accentuated throughout the paper. II. What Is Functional Testing? Functional Testing in a sense is to test every function individually; this meaning testing the function to the extent that the tester can say with confidence that the function works. Based off the definition earlier stated in the introduction; there is more to Functional Testing than just a one or two line definition. In fact, there are many components and relationships that need to be introduced before having a full understanding of what Functional Testing truly is in its entirety. There are different components to Functional Testing that will be elaborated here throughout the paper. Functional tests include: Boundary Value Testing, Equivalence Class Testing, Decision Table-Based Testing and many more. These are just some examples that the writer felt needed to be discussed more affluently. White Box functional test is usually called unit testing and concentrates on the functions as one might see them in the code. Black box function testing focuses on commands and features, things the user can do or select. Now that there is a more detailed description of Functional Testing; what are these different components and how do they i... ... middle of paper ... ...lect vital information about the capabilities and attributes of software and to help expose potential issues.

There are many solutions to these problems, but none of them are easily implemented. Each area of testing should be heavily modified. In math, for example, there is a str...
Chapter-4 describes the factors that differentiate one test case from other according as their fitness. How these factors are estimated mathematically for a particular test case using an example is given.
Sometimes within the Functional analysis, creating a testing situation leaves out something small, but crucial piece of information, that occurs within the natural surroundings (perhaps the kid most effective desires a green train). That is an extremely good instance of whilst different sources of statistics along with descriptive tests, direct commentary, and interviews are useful in reporting more information to make the testing situations seem real or help with treatment selections. Some other difficulty, is a Functional analysis may additionally produce a transient increase in problem behavior. “The problem behavior may maintain or take place more regularly if the evaluation is ended before the suitable behavior is taught. To avoid this, we end the analysis as soon as we've got sufficient records to teach us something about the behavior” (Hanley, Iwata, & McCord, 2003).
Testing must be performed on a pre-established schedule and will be executed under supervision of the qualified individual to validate the sampling; besides, must be implemented by third party testing services, and the Instruments used for analysis should be calibrated in accordance with established procedures.
Second I will describe what these tests are used to figure out and how they are carried out.
Manual testing is laborious activity which involve tester to perform the job accurately .Also the tester should hold below qualities in order to successfully test the test cases
In the past, most software tests were performed using manual methods. This required a large staff of test personnel to perform expensive, and time-consuming manual test procedures. Owing to the size and complexity of today's advanced software applications, manual testing is no longer a viable option for most testing situations.
Delivering a quality product is not solely down to how good the developer is, even though that helps, it is down to the quality of the original analysis and understanding of the requirement. Software testing is carried out to provide developers with a report on the quality of the program or application under testing. It allows the business to get an objective and informative view of how the product works. The purpose of testing is to resolve as many issues as possible before it is released. Each of the following testing principles help play a part but collectively they look to provide a working solution.
Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. “Software testing is arguably the least understood part of the development process” and is also a “time-consuming process that requires technical sophistication and proper planning” (Whittaker 71) It is important to comprehend this concept by understanding the different characteristics and aspects of software testing, and then to examine the techniques, procedures and tools used to apply this concept. This will enable the user to realize the problems faced by software testers and the importance of software testing.
After computing the F-test ratio value, decision as to whether accept or reject the stated null hypothesis. Reject hypothesis if the computed value is greater than the tabular value, accept if otherwise.
