IntroductionThis Exercise Book provides you with 600 exercises on white-box testing techniques which you may comeacross during your ISTQB Foundation Level exam. Questions refer to code coverage which is an analysismethod that determines which parts of software have been executed (covered) by the test suite and whichparts have not been executed. In this book statement coverage and decision coverage have been covered. Sincefor many functional testers testing pseudocode is not obvious enough, this book will help you understand howto answer questions related to code and pseudocode.

Chapter 1. Code and pseudocodeThere are a number of ways in which code can be provided in exam question. It may be a piece of a real code.

PHP code example:

if ($t<"20")

{

echo "Have a good day!";

}

else

{

echo "Have a good night!";

}

which is translated in pseudocode as

IF ()

{

;

}

ELSE

{

;

}

JAVA code example.

if(var%2 == 0)

System.out.println("Have a good day");

else

System.out.println("Have a good night")

which is translated in pseudocode as

Chapter 1. Code and pseudocode 3

IF ()

{

;

}

ELSE

{

;

}

C++ code example. {lang=”c++”}

if ( a <= 10 )

{

cout << "Below 10" << '\n';

}

else

{

if ( a < 60 )

{

cout << "Below 60" << '\n';

}

which is translated in pseudocode as

IF ()

{

;

}

ELSE

{

IF

{

;

}

}

Despite the way code is provided, it should always be read and understood in the same way. It is a commonpractice that during an exam code is presented as pseudocode.Pseudcode may be a simple text.

Chapter 1. Code and pseudocode 4

If

card number is valid then perform transaction

In other case

print information about failure

End

which is translated as

IF ()

{

;

}

ELSE

{

;

}

There is also a possibility that pseudocode will be presented in the form of a graph.

Chapter 1. Code and pseudocode 6

which is translated in pseudocode as

IF ()

{

;

}

ELSE

{

;

}

Pseudocode can also be provided in a like-a-code way. Though it is not a real code, it looks like one.

IF

THEN

ENDIF

IF

THEN

ELSE

ENDIF

which is translated in pseudocode (used in this book) as

IF ()

{

;

}

IF

{

;

}

ELSE

{

;

}

For a purpose of this book we will use one notation of pseudocode. However, during an exam one may alsocome across a notation written in a standard code.
