Q:

Which of the following is not a static testing technique?

A) Inspections B) Data flow analysis
C) Error guessing D) Walkthrough
 
Answer & Explanation Answer: C) Error guessing

Explanation:

Static Testing, a software testing technique in which the software is tested without executing the code. This Techniques provide a powerful way to improve the quality and productivity of software development by assisting engineers to recognize and fix their own defects early in the software development process.

 

It has two parts as listed below:

Review - Typically used to find and eliminate errors or ambiguities in documents such as requirements, design, test cases, etc.

Static analysis - The code written by developers are analysed (usually by tools) for structural defects that may lead to defects.

 

In this software is tested without executing the code by doing Review, Walk Through, Inspection or Analysis etc.

 

Hence, Error guessing is not a static software testing technique.

Q:

Unreachable code would best be found using

A) code inspections B) a static analysis tool
C) code reviews D) a test management tool
 
Answer & Explanation Answer: C) code reviews

Explanation:

Code review is a software quality assurance activity in which one or several humans check a program mainly by viewing and reading parts of its source code, and they do so after implementation or as an interruption of implementation.

Q:

What resources are used when a thread is created? How do they differ from those when a process is created?

Answer

When a thread is created the threads does not require any new resources to execute the thread shares the resources like memory of the process to which they belong to. The benefit of code sharing is that it allows an application to have several different threads of activity all within the same address space. Whereas if a new process creation is very heavyweight because it always requires new address space to be created and even if they share the memory then the inter process communication is expensive when compared to the communication between the threads.
