12. Types of Testing:
Unit Testing
Integration Testing
oTop down integration
oBottom up integration
oSmoke Testing
oRegression Testing
Black Box Testing
White Box Testing
Testing is a process of executing a program
with the intent of finding an error in a program. Test
case is one that has high probability of finding an yet
undiscovered error
TESTING
13. Integration Testing
Integration testing is a logical extension of unit testing. In
its simplest form, two units that have already been tested are
combined into a component and the interface between them is
tested.
Integration testing strategies:
Topdownintegration
Bottomupintegration
Smoketesting
Regression Testing
14. Unit Testing
The primary goal of unit testing is to take the smallest piece of
testable software in the application, isolate it from the remainder of the
code, and determine whether it behaves exactly as you expect.
Is the error due to a defect in shape module
Is the error due to a defect in tool module
Is the error due to defects in both the modules
Is the error due to a defect in the interface between the module
Is the error due to a defect in the test?
15. Top down Integration
The highest-level modules are tested and integrated first. This
allows high-level logic and data flow to be tested early in the process
and it tends to minimize the need for drivers. Need for stubs are reduced
in test management and low-level utilities are tested relatively late in the
development cycle.
Bottom up Integration
The lowest-level units are tested and integrated first. These
units are frequently referred to as utility modules. By using this
approach, utility modules are tested early in the development process
and the need for stubs is minimized. Like the top-down approach, the
bottom-up approach also provides poor support for early release of
limited functionality.
16. Smoke testing
Smoke testing is carried out testing along functional data and
control-flow paths. First, the inputs for functions are integrated in the
bottom-up pattern.Degree of support for early release of limited
functionality is tested. Need for stubs and drivers is minimized
Top down Integration
Regression testing is done do so by rerunning existing tests
against the modified code to determine whether the changes break
anything that worked prior to the change and by writing new tests where
necessary. Adequate coverage without wasting time is considered when
conducting regression test.
17. Black Box Testing
Black Box Testing is testing without knowledge of the
internal workings of the item being tested. For example, when black
box testing is applied to software engineering, the tester would only
know the "legal" inputs and what the expected outputs should be, but
not how the program actually arrives at those outputs.
Black Box Testing Strategies:
Needs no knowledge of implementation, including specific
programming languages
Tests are done from a user's point of view
Ambiguities or inconsistencies in the specifications are Exposed
if any.
Test cases are be designed as soon as the specifications are
complete
18. White Box Testing
White box testing strategy deals with the internal logic and
structure of the code. White box testing is also called as glass,
structural, open box or clears box testing. The tests written based on
the white box testing strategy incorporate coverage of the code
written, branches, paths, statements and internal logic of the code
etc.
Advantages of White box testing
I) As the knowledge of internal coding structure is prerequisite, it
becomes very easy to find out which type of input/data can help in
testing this effectively.
Ii) Code is being optimized
iii) Extra lines of code are removed which can bring in hidden
defects.
21. ::SHAPE MODULE::
Shape module implemented using
“graphics.h” header file.
Shapes available in graphical tool kit is
circle,rectangle,ellipse,polygon and line.
The shapes are with the basic concept of
mathematical functions(x & y points).
22. :: SHAPE MODULE
::
SUBMODULE DESCRIPTION
Line Draws a line in the drawing space.
Click and drag the cursor to draw the
lines to the desired length : void
line(int x1, int y1, int x2, int y2, int
color)
Circle Draws a circle in the drawing space.
Click and drag the cursor to draw the
circle to the desired shape and size :
void circle(int xc,int yc,int r, int color);
Rectangle Draws a rectangle in the drawing
space. Click and drag the cursor to
draw the rectangle to the desired shape
and size : void rectangle(int x1, int y1,
int x2, int y2, int color)
Ellipse Draws an ellipse in the drawing
space. Click and drag the cursor to
draw the ellipse to the desired shape
and size : void ellipse(int xc,int yc,int
rx,int ry, int color)
Polygon Draws a polygon in the drawing
space. Click and drag the cursor to
draw the polygon to the desired shape
and size : void polygon(int xc,int yc,int
rx, int color)
23. ::TOOLS MODULE::
Various colors can be used to draw the
shapes in graphical tool kit.
The ‘Pencil’ tool allows free hand drawing
in various colors.
Essential painting items such brush
airbrush in different shades
24. :: TOOL MODULE ::
SUBMODULE DESCRIPTION
Pencil Allows freehand sketching in the drawing
space. Click and drag the cursor to draw
the desired shape of desired size.
Color Depicts colored shape and drawings.
Select one of the available 18 colors and
draw the desired shapes of desired size :
Eraser This tool just erases the selected part of
the image. Click and drag the cursor to
erase the objects in the workspace
Brush When you drag the pointer, the airbrush
sprays with the foreground color.
Clear This tool clears the entire workspace
irrespective of the contents in the
workspace.
33. :: CONCLUSION ::
This project is developed to nurture the needs
of a graphical user by embedding all the functions of
graphical tool in a programming environment.
Future version of this software will include
options for importing pictures and save option which
will enhance the current version 1.0.Thus the
graphical toolkit is developed and executed
successfully.
