This document describes the test plan for the Gifitti application developed for 3XA3 at McMaster University.  

\section{General Information}
\subsection{Purpose}
The purpose of the testing plan is to establish a set of tests that will test the product in its entirety to ensure that it fulfills the intended purpose. This would be accomplished through verifying if Gifitti satisfies the different functional and non-functional requirements that were assigned to it. Having test plans for any product is essential to be able to understand how well the product is satisfying the client’s needs and if there is room for improvement.
\subsection{Scope}
This testing plan is utilizing different testing methods, automated and user created, and various techniques, black box and white box testing, to establish if the project has any need for improvement. Two different products will be analyzed through these tests, the Proof of Concept and the first iteration of the final product. Proof of Concept will be tested to ensure that a basic representation of the product was demonstrated while the requirements should be tested when the first iteration of the final product is completed.

\subsection{Overview of Document}
The testing plan is broken up into distinct parts. Under the heading Plan, the basic information will be given on the product and the tests. System Test Description will contain the specific tests for the functional requirements stated for the product. These tests will broke down into what type of tests they are and the results they achieve depending on their specific input. Testing for non-functional requirements will follow the same format where input will be given and the output will be measured for all of the provided non-functional requirements. Under tests for proof of concept, the same format will be utilized as the functional testing but it will not be testing
the requirements for the project but for the goals of the proof of concept. Furthermore there will be tests to compare Gifitti to the 
original product it was based on and unit testing plans to ensure correct output is achieved through proper internal functions.


\section{Plan}
\subsection{Software Description}
Gifitti is a software product that allows the common user to be able to manipulate for their entertainment or commercial needs. 
With an intuitive design, it allows a person who has never done any kind of graphical editing to be able to manipulate a GIF to achieve
the person's particular design. This product can also serve a commercial purpose in allowing the creation of sprite spreadsheets and 
a quick production of GIFs.

\subsection{Test Team}
The team to implement the test plan for the project will be Pavle Arezina, Riley McGee, Nicolai Kozel.
\subsection{Automated Testing Approach}
This test plan will utilize automated testing for verification that the GIF manipulation functionality changes the GIF properly. Such that the exported GIF image will match what is created by the user of our product.
\subsection{Testing Tools}
The only tool to be utilized to test this product will be the Microsoft Unit Test Framework that is native with Visual Studio.
\subsection{Testing Schedule}
		
See Gantt Chart \href{https://gitlab.cas.mcmaster.ca/kozeln/Gifitti/tree/master/ProjectSchedule}{ here.}

\section{System Test Description}
	
Testing allows the developers to detect errors that the test cases cover. With the functional and non-functional requirements the developer knows the expected results and can evaluate the results of tests accordingly. Pass or fail values are assigned to executed tests discreetly unless the test is to have an error tolerance for passing.
\subsection{Tests for Functional Requirements}

Functional requirements prescribe what services the software should provide. They capture the intended software effects on the environment and applicability conditions. These tests ensure that the functional requirements of Gifitti are fulfilled or the tests will help to discover any functional requirements not satisfied by Gifitti.

not continue the operation and inform the user that disk space needs to be cleared before continuing.

\end{enumerate}

\section{Tests for Proof of Concept}

The proof of concept is a demonstration of the feasibility of the software project. Ensuring that the Proof on Concept is producing the intended results can only be achieved through tests specifically designed to root out any of the errors present in the build of the proof of concept. By successfully testing the proof of concept and achieving the intended goals, it is shown that the software-to-be is a possible entity.

\subsection{Opening a GIF file for playback}
		
\paragraph{Open GIF}

\begin{enumerate}

\item{OpenGif-01\\}

Type: Manual Functional 
					
Initial State: Program must be in normal state (form window is open and playback window is blank).
					
Input: GIF File 
					
Output: GIF is shown in playback window of the form. 
					
How test will be performed: Click open button, select a file of type .gif, and verify that the GIF loads and begins to playback within the form window. 				

\end{enumerate}

\subsection{Saving a GIF file's frames}

\paragraph{Save GIF}

\begin{enumerate}

\item{SaveGif-01\\}

Type: Manual Functional 
				
Initial State: Program must be in playback state (form window is open and playback window is playing GIF).
					
Input: GIF File  
					
Output: GIF's frames are saved as .bmp in folder specified.  
					
How test will be performed: Click save frames button, select a folder, and verify that the GIF's frames are saved to the specified folder as .bmp.				

\end{enumerate}
	
\section{Comparison to Existing Implementation}	

\subsection{Graphics/UI}
\begin{enumerate}
\item GIF playback resolution is the same or better than Gif Viewer.
\item Program has the same button scheme as Gif Viewer (Open button to open file, Extract Frames button to save frames).
\item Program has a help menu available that is similiar to Gif Viewer, but is available at all times. 
\item Program's color scheme and design resembles Gif Viewer.
\end{enumerate}
\subsection{Performance}
\begin{enumerate}
\item GIF playback is at the same smoothness/framerate or better than Gif Viewer.
\item Opening and saving a file takes the same amount of time or less than Gif Viewer.
\end{enumerate}
				
\section{Unit Testing Plan}
The unit testing plan is the devised set of tests that the code and the system modules must undergo regardless of the system integration level. Unit testing allows the project to have white box testing on the individual system components where each unit test can be executed via testing frameworks in C Sharp.
\\
\\
The testing framework being utilized is the native Visual Studio unit testing framework: Microsoft.VisualStudio.TestTools.UnitTesting.

\subsection{Unit testing of internal functions}
Unit testing will be done on system methods that return a value, or modify known objects in an expected way. A metric for passing is to be used on all methods with an error tolerance, such as manipulation of a GIF (where slight variations can exist in files that present the same). A method with no expected error tolerance should be implemented as discreetly pass XOR fail. All unit test inputs must fall in a known domain where the expected output can be assumed. No stubs will be required for unit testing of functions. Image reading is needed as a driver for any method using GIFs or other image types. Any written unit test must utilize the C Sharp attributes for Unit Testing provided by the framework. This ensures the system does not build the testing package into the consumer version of the software. We plan to have unit testing cover approximately 50 percent of our major methods due to project time constraints.

\subsection{Unit testing of output files}		
To test the validity of outputted GIF images, the testing system will hold image resources of input frames, input GIFs, as well as the expected GIF outputted. A known GIF should be manipulated and then compared to the expected GIF in a frame-by-frame matter. To exclude meta-data issues associated with GIF images, each frame should be cast to a known image format such as a bitmap, then compared pixel-by-pixel. Frames should have a 100 percent pixel match for the expected GIF to pass. A method for casting Frames to bitmaps and then comparing the pixels, should be added to the testing package prior to testing GIF manipulation. This function can then be verified by simply sending the same image(s) as parameters.
