COCS 4351 EXAM 4 QUESTIONS AND ANSWERS
ELABORATIONS!!
1.A technique to select minimum test cases for the Black Box Testing is
called Equivalence Testing and Boundary Value Analysis. It divides the
Input or Output Specifications in Classes.: equivalence
2.Nested if statements rule of thumb:
- if statements nested to a depth greater than should be avoided as
poor Programming Practice: 3
3.The Integration Process must be run by:: the SQA group
4.These are examples of 4GL Languages:: - SQL
- RoR
5.PHP code runs in a web browser.: False
6.Many PHP applications run on Linux with and Apache web server
and MySQL as the database: True
7.What file extensions does a PHP script have?: .php
8.What does the code output?
$test = "adios";
echo "$test test";: adios test
9.What output is produced by the PHP script?
<h1>This is a test</h1>
echo "This is only a test";: <h1<h1>This is a test</h1>echo "This is only
test";
10.Must PHP statements be terminated by a semicolon?: yes
11.Which code segment produces a notice error message?: $count =
2; echo $COUNT;
12.The var_dump(variable) function outputs the data type of a varaiable.
What is the output of the code below?
$x = 1.23;
var_dump($x);: float(1.23)
13.These are technique for the Testing Workflow:: - Glass Box Testing
- Code Walkthrough and Inspections
- Black Box Testing
14.Black Box Testing is also known as Testing to :
specifica- tions
15.Glass Box Testing is also known as Testing to : code

, 16.One measure of the complexity of a code artifact is the number of lines
of code.
Another measure of complexity is the complexity M (McCabe)
which measures essentially the number of decisions (branches) in the code
artifact. It is also a good measure of number of faults.: cyclomatic
17.In one experiment, artifacts with the Cyclomatic Complexity M greater tha
were shown to have statistically more errors.: 10
18.The art of testing is to select a small, manageable set of Test Cases to:
- the chances of detecting a fault while
- the chances of wasting a Test Case: maximize minimize
19.Consider the statement
< condition 1 > && < condition 2 >
The semantics of the && operator are such that if < condition 1 > is false,
then < condition 2 > is not evaluated. What is the technical term for this?:
- short-circuit evaluation
- minimal evaluation
20.In choosing the Implementation Language, the following techniques
are used:: Code Benefit Analysis
21.Client-side data validation makes server-side validation unnecessary: -
False
22.Which statement produces a parse error?: $owner = 'Pam's'
23.3 + 5 * 2 = ?: 13
24.$points = 10;
$points--;
$points + 2 = ?: 11
25.What compound assignments operator makes $points become 2.5?
$points = 5;
$points 2;: /=
26.What value is $message?
$message = "Top";
$message .= "secret";: Topsecret
27.What is value is $points?
$points = 2;
$points *= 3 + 1;: 8
28.indicate if the expression evaluates to true or
