Consider the following line of code: if (x < 12 || (r – 3 > 12)) Write three valid mutants of this ground string (based on

Nata [24]

Answer:

See explaination

Explanation:

Mutation Testing:

Mutation Testing is a type of software testing where we mutate (change) certain statements in the source code and check if the test cases are able to find the errors. It is a type of White Box Testing which is mainly used for Unit Testing. The changes in the mutant program are kept extremely small, so it does not affect the overall objective of the program.

We say a mutant is valid if it is syntactically correct. We say a mutant is useful if, in addition to being valid, its behavior differs from the behavior of the original program for no more than a small subset of program test cases.

VALID MUTANTS

1. if (x < 12 && (r – 3 > 12)) LOR

2. if (x < 12 || (r – 3 < 12)) ROR

3. if (x < 12 || (x – 3 < 12)) IVR

INVALID MUTANTS

1. if (x < 12 ||(r – 3 > 12) UPR

2. if (x < 12 (r – 3 < 12)) MLO

3. (x < 12 || (x – 3 < 12)) CSM

Note:

LOR: LOGICAL OPERATOR REPLACEMENT

ROR: RELATIONAL OPERATOR REPLACEMENT

IVR: INVALID VARIABLE REPLACEMENT

UPR: UNBALENCED PARANTHISIS REPLACEMENT

MLO: MISSING LOGICAL OPERATOR REPLACEMENT

CSM: CONTROL OPERATOR MISSING REPLACEMEN

The tools that cyber criminals often use, including computer viruses, worms, trojan horses and spyware, are called __________. q

ivanzaharov [21]

The options were:

-malware
-spam
-Denial of Service
-Hacking

The correct answer would be Malware. Here is why: Malware refers to a program or script that will affect a target device in a negative way, it cant be hacking because it is a topic, not a tool. Denial of Service is a type of attack that temporarily shuts down servers after a number of requests a device(s) make exceeds the number of requests it can take in a certain amount of time. Spam is either an advertising email from a third party company that bought your email from a list server from a service you gave your info to, like Facebook. Or spam could be a social engineering attack sent by someone trying to harvest your credentials from an email source your email server found untrustworthy.

Please message me if you need any more help with this stuff, I am doing a lot of hacking projects right now and I think I would be a great contact!

Hope this helped!
