software testing

TESTING

REGRESSION TESTING:

Regression testing is a type of software testing which verifies that software which was previously developed and tested still performs the same way after it was changed or interfaced with other software. Changes may include software enhancements, patches, configuration changes, etc.

SMOKE TESTING:

Smoke Testing, also known as “Build Verification Testing”, is a type of software testing that comprises of a The results of this testing is used to decide if a build is stable enough to proceed with further testing.
non-exhaustive set of tests that aim at ensuring that the most important functions work.


CLEAN ROOM TESTING:


Clean room testing is a technique extracted from a software development practice
known as Clean room Software Engineering. The original purpose of Clean room testing
was to exercise software in order to make mean time to failure (MTTF) measurements
over the course of the project. In this chapter, Clean room testing is applied to the
problem of why customers find problems in games after they have been through thou-
sands of hours of testing before being released. If one measure of a game's success is
that the users (players) will not find any bugs, then the game team's test strategy
should include a way to detect and remove the defects that are most likely to be found.


AD-HOC TESTING:

Ad hoc testing is a commonly used term for software testing performed without planning and documentation, but can be applied to early scientific experimental studies.
The tests are intended to be run only once, unless a defect is discovered. Ad hoc testing is the least formal test method. As such, it has been criticised because it is not structured and hence defects found using this method may be harder to reproduce (since there are no written test cases). However, the strength of ad hoc testing is that important defects can be found quickly.
It is performed by improvisation: the tester seeks to find bugs by any means that seem appropriate. Ad hoc testing can be seen as a light version of error guessing, which itself is a light version of exploratory testing.


TESTING LIFE CYCLE:


A software testing life cycle (STLC) is a set of steps used to test software products. Software testing is a critical part of preparing software for use, and a STLC helps make this process more sophisticated, consistent and effective.


WHITE BOX TESTING:

White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of testing software that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing).

BLACK BOX TESTING:

Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.

How are Female characters represented in games?

The way of men and women in video games, as in other media, is a subject  in gender studies and is discussed in the context of sexism in video gaming.
Although women make are half of the video game players, they are significantly underrepresented as characters in mainstream games/ main role, despite this the iconic heroines such as Samus Aran or Lara Croft. The portrayal of women in games often shows traditional gender roles, sexual objectification or negative stereotypes. Male characters are often stereo typically depicted as big and muscular, and LGBT characters have been slow to appear in video games as a result of the heterosexuality of the medium.This indicates that how genders are portrayed in games can influence players' perception of gender roles, and that young girls prefer to play a character of their own gender much more than boys do. On average, female-led games sell fewer copies than male-led ones, but also have lower marketing budgets.

Graphic Specification



Client Needs:

Client needs is where the person or for example your boss has asked you to design all of the things that they have listed on there brief and design it they way they want it and to there standards. Usually this type of work has always got to be top standard depending on what your are creating.


Audience:

With the brief, the target audience can very and briefs can be rated. For example if you are design a game were sex and violence is involved this would be rated an 18+ game because it is not appropriate for under teens and children under the age of 18+.


Thumbnail sketching:

Thumbnail sketching is where you are just roughly coming up with ideas for the brief you are given and these sketches should take you up to 10 to 15 seconds max. So the final result is you have a lot of ideas done on paper and then you pick out a few to work on and improve.


Visual style:


This where in the brief The client can ask fro a certain style of the art in the design, this can be photo-realism to a cartoon look such as anime and 2D pixel (retro) theme. Depending on what game it is for example, if it was based for children over 7 then it is usually cartoon themed and 2D and sometimes 3D but this is down to what the client wants it to be as well.


Composition:

This is were the rule of thirds comes in to place. In the video game this is were everything looks perfectly in place, this can be the health bar to how the Background and the setting is laid out. So it makes the game look professional and not all over the place.


Typography:

The typography sets the mood and the atmosphere of the game that you are making. For example of your game was a fighter combat game then your logo and the typo needs to be sharp and tough looking to go with the theme of the game, and also quite intriguing to catch the target market.


Technical considerations:
This is where you have got all your assets and your making the product of the game, for example this is were you would name all your file assets and what they will be for your game and to the briefs standards. The is also file compression's and optimising, this is were you are reducing the size of the file and so its not taking up so much space as you are also restricted to how much memory you have to make it. When naming the files you also need to know what format it is so this can be a GIF, JPEG e.g. You have to manage these files as well so you know whats what.

Unit 78: Digital Graphics for Computer Games

BTEC Level 3 Games Design
Unit 78: Digital Graphics for Computer Games
Assessor name: Josh Rai

Student Name: Leah Doohan



In the assignment I will be describing about two games, one 3D and the other 2D. I will be talking about the graphics of the game and the contrast. The types I will be showing are Artistic style, Computer game graphics, Pixel, Types of Digital Graphics, File Extensions, Compression, Image Capture, Optimising, and Storage of Image Assets.

The games that I have chosen:
3D: Beyond two souls - 2013
2D: Yoshi’s Island DS – 2006

Art style: Beyond two souls 3D


The art style for this game is photorealism. This game is as beautiful as the way it has been displayed. What I mean by photorealism is that it looks like it is a photo from real life but it is not, it really plays with your mind but it is very clever. In the game, the main character (Jodie) has so much detail from the face all the way down. You can even see the different skin tones on the face to the mouth etc. Through the game you see a lot of scenery as there’s parts that would you go through, bars, trains and even power stations and they all look so realistic.
Jodie’s hair is also a good way so show photo realism, what makes this so believable is that the hair flows with the body and also how the way the hair settles is just amazing, you can even see the shine on the hair when you pass street lights are some sort of light. This also goes with the skin reflecting light as to the clothes too. There is a part in the game were you are training is the army, you are doing a routine exercise and through it the weather looks so real and the way the mud splashes look is just genius. This really makes the player see the moods of the game and also effects the player’s emotions while playing it.

Here in a link to show you the mud and the way the weather looks in the game when Jodie is doing the excise/ go to 6 minutes and 26 seconds:


Art style: Yoshi’s island 2D



The art style for Yoshi’s Island is pixel Art, Pixel Art is an old retro type of style but is one of my favourites.  It is a mixture of colours (elements) on a Grid. This art is bold and very colourful by the way the characters and the game scenery have been designed. The characters in the game are 2D flat based but sometimes they look 3D by the way the colours have been shown on them same with the backgrounds of the game.
This can be similar to the light tones that I explained earlier how in the curtain parts of the game, the shadow parts of the characters in Yoshi goes down the pipes have different shading to the way his shading tones are on the surface.  The toning is usually more in the background then more on Yoshi.

Here is a link to show you the shadowed parts of the game by the art style/ go to 2 minutes 37 seconds:

Computer game graphics: beyond two souls 3D

Concept art is one common type of design in production. This type of design can be used in video game but can be used in other ways such as animation, films and architect design; also it is used in a lot of illustrations. The type of art is before the final project. For example it is how the characters and the scenery is going to be designed. For beyond two souls they did something different with the way they were going to make their characters. They used motion Capture (MC) this is very good way to make your characters look exactly like you want them to look. For this the creators used Ellen Page and the main character Jodie and for her canceller in the game they used Willem Dafoe. 
Motion capture was also used for all of the stunts in the game and scenery. To summarise what motion capture is, it is a software program that allows you to pick up the pointed on the actors in 3D and is able to put there body structure on to the computer for then the designers to add the final details to the characters and scenery. For example, colour and skin tones, lighting and textures to the game as well. This is also how they created Aiden’s ghostly figure and effects too as the glow follows Jodie in the game and the way they had to make that look 3D is by doing the same effect with the characters with the special effects too. (Aiden is Jodie’s dead brother, another character) You can see in the photos at the top and below, this is what motion capture looks like.Image result for motion capture beyond two souls

Here is a video showing how they did motion capture:

Here is a video to show the concept art and the designs leading up to it:

Here is an Illustration of Aiden in the image bellow:

Computer game graphics: Yoshi’s Island 2D


The concept art from Yoshi’s island is a lot different to how beyond two sols displayed their game. As this is a 2D game they didn’t use motion capture they used 64- bit machine. This is retro type of game and in this time this game was based for children to play and that is why this game is simple and colourful to capture the eye. Artoon were the designers that created the concept art for the game, they wanted to make the game look as if it was drawn by crayon in curtain parts of the game. They made a texture for it that looked like crayon.


Also for the concept art, the menu screen is very creative by the way they have displayed it, they make it look 3D by the Island that has been shown in he middle rotated 360, so you see the whole island at the beginning. The only thing on the menu screen that is 2d is the logo. Even the art for the sky is animated and made to look 3D with the clouds in the background and the different shades of blue in the sky.


The colour scheme for this was very basic but in a way would make you want to play it. The character Yoshi in the game came with a choice of different colours for you to choose which one you wanted to play as which made the game that a bit more funnier. The game its self is creative by how the different levels are designed and are very similar to super Mario bros. This game was meant to be a sequel to the Mario bros but the creator Shigeru Miyamoto wanted Yoshi to have his own spin off in a sense, have if own story to how he got to the Mario brothers.

Here is a link to show you the main menu you 360 terms/ go to 26 seconds:

Pixel / Resolution: beyond two souls 3D / Yoshi’s island 2D

A pixel is an element that is visual on a display screen wither you are playing a videogame on the console or pc. An image consists a lot of pixels just to make one full image. Higher resolution images is it harder to see the pixels unless you zoom in as the about of detail is in that image and depending on how big the picture is. In Beyond two souls the resolution is very high as the concept art that goes with it is very detailed. This also goes with the size of the pixels would roughly be 1920 x 1800 as this is also to do with the hardware running the game as well.
With Yoshi’s island you can’t customise as it is retro and doesn’t have that advanced settings, also it’s a DS game so it’s not running on such a good hardware compared to beyond two souls. The size of the pixel resolution would be 360 x 480 as it’s a small screen display. Most games now have advanced settings that allow you to customise the way the display is if they don’t have a limit to 1800p. In beyond two souls you can see the high resolution and detail to the game.


As you can see the lights and the colours in this image is strong and powerful and the resolution is high with the pixels too in this. The main menu is also amazing on how it is done as each chapter you finish the menu screen updates Jodie to an older version of her self as you play through her story.
Here is a link to show the detail of the main menu screen display of beyond two souls:

This video will show you the intro to Yoshi’s island so you can see the difference in detail.
Here is a link to show some game play of Yoshi’s island / go to one minute 18 seconds:




Types of digital graphics: Beyond two souls 3D / Yoshi’s Island 2D

Digital graphics is the different scenes and backgrounds of the game; this also is if you playing as curtain game that needs extra navigation there are usually a little map on the display screen. This can be heaths bars too and other things that need displaying on the screen the backgrounds are the key to really showing the games setting and giving you the mood of what the game is all about. 3D games it is a lot more visual then a 2D game because the character is able to go in any direction of the game un like 2D which you can only go a curtain way on the screen. This doesn’t mean that 2D can’t be detailed. In 2D the screen is mostly the background and it follows the character as it goes through to the next level.

For beyond two souls there are so many parts of it that are just brilliant, for the start menu as I explained earlier, it shows Jodie in the stages of her growing up through the game. And the in game display has a few features come up depending on what part of the game you are playing or when the player is in control.



There is also box art which is what the game comes in and what is in the box. So the front of the box will have Illustrations of the game which catches the eye and then the content inside will be How to play the game, as booklet to show you all the controls and also items in the game and what they mean this can also be for Yoshi’s Island as well. There are also posters for the game to make sure sales go well and for people to go and by it, this is printed media. This can be shown in adverts, trailers and posters that can be shown on the sides of the bus. Here are examples of printed media, (The playing disc is also be decorated).

Here is a link to show you these parts of the features I have shown / go to 1 hour, 45 minutes and 51 seconds:

For Yoshi's Island there is a few features to the game, most of them involve you interacting with the timing of when to shoot and what you’re aiming for.  The way it is done is simple but fun. You are usually shooting eggs at enemies that are being made by Yoshi himself. The number on the screen symbolises how many flowers you have picked up and that also tells you that you have been given an extra life.




File Extension / Compression: Beyond two souls 3D / Yoshi's Island 2D

 A file extension is where it is the end of a file name that helps in defining the type of file it is on what system you are using. So for example if you were saving a file on illustrator you would save it as image.jpg.  The most common of formats are JPEG, GIF and also Mp3 and 4 for converting music.  So for games developers they wanted lossless, this means that the image is reduced without losing any of the quality for that image. When making game it is important to make sure everything is labelled so that it stops wasting time on trying to find a file and to decrease the amount of bugs to fix. The file being labelled makes it lossy. As beyond two souls is a big game there would be so many assets to find and doing  so they need to be all labelled to stop further bugs in the game and to all of the further updates into the game too that would need to be linked with the game. For Yoshi's Island it can be just as difficult but not as bad because there are fewer assets to the game and less bugs to fix.









  Image capture: Beyond two souls 3D / Yoshi's Island 2D

Image capture is where you can take a photo in real life and also from the internet. It is easier now to capture an image as technology has progressed through the years. The most popular way is by taking photos by your phone or tablet or any device that has a camera to it can capture an image. You can Also do it by getting a usual standard camera but that has now advanced to DSLR which is allot of higher quality. You can also take screen shots of the internet and also on console while in the game play.

For Beyond two souls tried to do a similar layout to San Francisco for the scenery but adding in there on details to you can't really tell, through the game there are lots of different areas that look similar to real life places but changed in the way that you can't tell. An easier way to show an example of image capture for this s how they did the actors from real life with motion capture which I explained earlier.



For Yoshi's island on the other hand didn't really use this that much as it was all designed and illustrated on to the computer. Also this game is more cartoon based them real life but that is what makes it interesting. Which this image capture would be internet form.


Optimising: Beyond Two souls 3D / Yoshi's Island 2D

Optimising is making the best of use of a resource or a situation. For a game this would be making sure the game is running to its full capability and the resolution is at its highest. This also can be making sure game has no bugs or glitches while playing.  Also this can be as making sure it is on the best software and hardware to run. For beyond two souls this will have to be a big hardware and operating system for it to run smoothly. For Yoshi's Island it is Easier to run smoothly as it doesn't need s big operating system to run it and for it to run smoothly is to making sure everything is to its highest ability, this includes resolution but doesn't need much as it is on DS.


Storage of assets: Beyond two souls 3D / Yoshi's Island 2D

Storage is very important in making games as the developers do not want to be able to refer back to a curtain part in the game and having to go through all of the assets just to find that one part so they can adjust it to the way they would like it to be. This goes back to file extensions as labelling all the assets in storage to go Easily back to the item you were looking for.  Beyond two souls has allot of assets from when the scenery with each tree to the parts in the game were the characters are dressed in different clothes and what items that they are going to use. For Yoshi's island this would be a lot easier to find as there are less assets to find.
