Software Testing
Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. “Software testing is arguably the least understood part of the development process” and is also a “time-consuming process that requires technical sophistication and proper planning” (Whittaker 71) It is important to comprehend this concept by understanding the different characteristics and aspects of software testing, and then to examine the techniques, procedures and tools used to apply this concept. This will enable the user to realize the problems faced by software testers and the importance of software testing.
Software testing is the “process of executing a software system to determine whether it matches its specification and executes in its intended environment” (Whittaker 71). It is often associated with locating bugs, program defects, faults in the source code, which cause failures during execution that need to be removed from the program. Locating and removing these defects is called debugging, which is different from the testing that establishes the existence of these defects. Specifications are crucial to testing because they identify correct behavior so that software failures corresponding to incorrect behavior can be identified. Failures can vary in their nature ranging from wrong output, system crash to systems using too much memory or executing too slowly. These Bugs in software can be due to untested code executed, u...

What Is Software Testing? And Why Is It So Hard? James A. Whittaker,IEEE SOFTWARE January/February 2000
The main protagonist for this story is Mr. Waythorn, he is the third and current husband of Alice Waythorn and the story is mostly told from his perspective. He is the main character of the story and works with Alice's second husband, Gus Varick. He is also the stepfather of Lily who is the daughter of the first husband of Alice; Mr. Haskett. He looks beyond the social stigma of marrying a woman who has been twice divorced. We see throughout the story Mr. Waythorn’s character undergoes some changes in the way he views his wife and her past relationships thereby making him a round character. Mrs. Waythorn is the antagonist of this story, it is obvious that the she has used all her marriages to advance her social standing, she redefines herself based on the level she attains, thereby refining who she is to those around her. We see all this from the perspective of her husband. After the glow of the honeymoon has died down Mr. Waythorn begins to realize that his perception of who Alice was before they got married was probably wrong. Alice is revealed to be more complicated as a character than we are initially presented with based on the perception of her current husband, so for this reason she is a round character.
Numerous leaders have made tremendous impacts throughout the history of the world. In this essay, I will compare and contrast the lives and philosophies of civil rights activists Dr. Martin Luther King, Jr. and Malcolm X. Dr. Martin Luther King Jr. and Malcolm X were prominent leaders during the Civil Rights Era. They both had very different philosophies and methods on the racial emancipation of African-Americans. Despite their differences, they shared a common goal to live in a society with equal opportunity and a world free of segregation.

Two of the most Influential Civil Rights Movement leaders were known as Martin Luther King and Malcolm X. Both of these leaders had different perspectives, actions and arguments. Being a minority in America is the toughest battle anyone could face but having leaders that speak up for those who can’t, create the biggest impact. The different approaches in society is what made Martin Luther King and Malcolm X impacts on their movements popular and strong that it is still discussed about today but seldom understood. Generally, they both fought for the same reason, which is gaining equality and justice in America as a minority. In this essay I will further break down and compare the importance of each one their perspectives, including Peace
Therefore, to address the challenges of the two kinds of testing Zhang et.al, (2012) proposed a two stage fuzzing process to effectively test complex program semantics (p.103). The...
News of source code theft jolted the software industry on February 12, 2004.2 Cyber criminals had stolen source code from Windows 2000 and Windows NT4.0. Windows 2000 and NT are the platforms on which the widely used home operating system of today, Windows XP, is based on. Luckily, only a small portion of code was stolen. Not nearly enough to build the entire Windows operating system. Through the use of peer-to-peer networking, the code was distributed in an underground hacker network. Eventually the source was spread onto public-access web sites, by which Microsoft confirmed the code was, indeed, real Windows code.
Jonestown massacre, led by Jim Jones, was known to be a massive genocide that took place in the jungle at Jonestown, Guyana, South America on November 18,1978. There were total of 913 people who died drinking the cyanide mixed kool-aid.
There are many solutions to these problems, but none of them are easily implemented. Each area of testing should be heavily modified. In math, for example, there is a str...

The Main purpose of testing is to check that software meets all specified requirements that guided its design and development. There are many types of software testing techniques that can be performed with in software development life cycle. Out of many software testing techniques, Acceptance testing (AT) is the key feature of software implementation. As the acceptance testing mainly constituents that the system should be acceptable by its owner or user it is also called as User Acceptance Testing (UAT). UAT is performed to ensure that the new system meets all the essential user requirements. It is the final testing activity performed by the customer to test for the completeness, correctness and consistency of the
Delivering a quality product is not solely down to how good the developer is, even though that helps, it is down to the quality of the original analysis and understanding of the requirement. Software testing is carried out to provide developers with a report on the quality of the program or application under testing. It allows the business to get an objective and informative view of how the product works. The purpose of testing is to resolve as many issues as possible before it is released. Each of the following testing principles help play a part but collectively they look to provide a working solution.
There are enormous software testing tools available in the market but the selection of the tool is based upon the software application. Now, We are going to discuss about top three tools and their techniques.
A definition of software testing has been narrated in different perspectives by many authors. Pressman defines “Testing is a set of activities that can be decided in advance which are further conducted systematically” [54]. “Training a program with the specific intent of finding errors before delivering it to the end
