Discussions Black Box testing and White Box Testing Black-box test design treats the system as ‘inaccessible’, so it doesn't explicitly use knowledge of the internal structure of the system. There are many advantages to black-box testing like: 1. Ease of use: We simply work through the application, as an end user like will it work on windows platform or not…

Extract of sample "Testing"

Download file to see previous pages White-box test design allows one to peek inside the "box", and it focuses specifically on using internal knowledge of the software to guide the selection of test data. There are distinct advantages to white-box testing like: 1. Thoroughness: As such, white-box testing is much more thorough in terms of what percentage of the application we can test. This helped us in finding out that it will overwrite the point character if you first enter it and then enter a number. 2. Stability: Delivers greater stability and reusability of test cases if the objects that comprise an application never change like the calculator whose multiplication is constant but whose exception was not correct. But there’s the flip side of the coin as well and each of these come with a few disadvantages as well. The Black-Box Testing Techniques lack accuracy and despite the ease of use lack thoroughness and it doesn’t look very stable to me. Other disadvantages include the fragility of scripts and lack of introspection that comes with no knowledge of the internal structure. ...
GUI testing JUnit testing Success of any GUI application depends on how it interacts through its user interface with different users. An application with invalid behavior or incorrect user interaction can lead to large problems. GUI testing is a process to test the application's user interface and to detect if the application is working fine functionally. GUI Testing includes how the application deals with keyboard and mouse events, how different GUI components like menu-bars, tool-bars, dialog-boxes, buttons, entry fields, list navigations, images etc. respond to user input and to ensure that the tasks are performed as desired. The GUI testing can be implemented either manually or through automated methods. Manual testing is often error prone as well as far from exhaustive thus automated approach is preferred. Automated GUI Testing is use of a software program to check if the application is working fine functionally. This includes automating manual testing tasks which are mostly time consuming and error prone. To test a GUI, we needed a good method of finding the components of value, selecting cells in a table, dragging things about, clicking buttons, etc. The events we test are similar to assembly language only these are applicable for GUI testing. What the ideal approach is in describing the expected behavior is that we clarify the developer's goals before penning the code can; this avoids overbuilding useless feature and the correlated feature sets. Below is the required refactoring of the Java calculator program using Test-Driven Development (TDD). There is no possibility of exception in multiplication function so exception part of code can be considered as a dead code and can be removed. Public DivideByZeroExeption(String s), this function can ...Download file to see next pagesRead More

Integration Testing and Systems Testing

... optimum safety of the individuals working on them. The primary objectives of Systems Engineering is to deliver the systems with optimum practical effectiveness including reliability, efficiency, safety, quality, maintainability, scalability, upgradeability and cost effectiveness. Systems engineering is carried out in a structured process framework called the Systems Engineering Life Cycle processes and is defined by the ISO/IEC 15288 standard [Magee, Stan. 2005]. The process framework is presented in the figure below at a high level: Figure 1: The process framework of Systems Engineering (Source: Bahill, Terry A. and Dean, Frank F. Dec. 1994.) The Integration and System testing activities are carried out after the “integrate” stage...

The Pros and Cons of DNA Testing in Law Enforcement

... use of new technologies. However, because these advances are still so new, it is not always possible to understand their full implications. As someone who is studying criminology and forensics, DNA testing will have a huge impact on the direction of my future career. But whether DNA testing is all good is a subject of intense debate—a debate that my generation will have to answer more fully. This paper will argue that although DNA testing is extremely useful to law enforcement it has potential pitfalls too. When looking at different criminological theories, anyone who intends to make a future in this profession will have to come to terms with pros and cons of DNA testing. The answers are not always so straightforward. An over reliance...

Effectiveness Of Clinical Testing Of Olfaction

...Effectiveness Of Clinical Testing Of Olfaction Abstract The sense of olfaction is considered to be the most basic of all sensory perceptions. The interpretation of olfactory stimuli occupies a very large portion of the brains of lower animals. In humans, this portion of the brain has been superseded by the extensive development of the prefrontal cortex; however, the sensory stimuli associated with olfaction continue to comprise an essential component of the perceptive capacities of the human brain. Unfortunately, this important sensory apparatus has received little attention, and its importance to health is frequently underestimated. Among the common tests of olfaction are measurements of odor detection, odor identification...

EMC Testing and Standards in Transient Immunity Testing

.... While it is possible to comp[ly with the elctronomagnetic compatibility after the completion of setting up the control roomIt is important to think of the electromagnetic compatibility principles during the design , it is also true that it will cost much less to have it desingend into the ssytem from the word go.It has been established that only a mere fifteen percent of the products that haven’t been designed with electromagnetic compatibility principles in mind pass the EMC testing (Paul, 2007; Keiser, 2007). Electrodynamics usually provides the basic foundation for all electromagnetic interference. When operating at low frequencies, the magnetic fields will often operate independently. However, when at high frequencies, the only...

School Searches and Drug Testing related employee misfeasance”. Ortega ( 709). Failure to act on time while waiting for enough evidence to warrant a search can result to irreparable damage that can have adverse effects on the particular government’s office. Therefore there is the need for random suspicionless search. If those kinds of searches work well for government offices, then they must work very well in public schools. General drug testing A decision was made by the Supreme Court to pass laws that allow drug and alcohol testing programs among employees, patients in hospitals and students in school. The Supreme Court allowed for warrantless drug testing among workers. This move was aimed at achieving mainly two objectives. First, it would make...

Animal Testing Should not Be Banned

...being and indeed, animal testing should not be forbidden considering that animal testing is beneficial for science field. One of the primary reasons of performing animal experiment is that animal testing is beneficial for science field. Scientists and doctors argue that every achievement in medical field in 20th century has relied on the use of animals in some way. Thus, scientists have prior knowledge and experience of using animal testing in carrying out experiments for many years (“National Academics Press” 12.) First, animal testing plays an essential role in developing the surgical field. According to Cooke (18), toxicologists have the...

What Is My Position on Drug Testing Welfare Recipients to Receive Their Benefits

...affects those who are and are not on welfare. Smith, Phillip. Welfare. Digital image. Raising Awareness of the Consequences of Prohibition. N.p., 26 Feb. 2013. Web. 28 Feb. 2013. In my research I have found to be two sides to this argument “Proponents say testing would help the recipients and protect taxpayers. Opponents argue that the practice is unconstitutional and mean-spirited.” (Vitter 141) Both parties make really convincing arguments and surely drove me crazy trying to choose a side “The proponents of drug testing welfare argue that it is irresponsible for any government to fund people who they know are using drugs” (Chelsea 2). It is true that there are drug addicts everywhere but let us...

Prenatal Testing for Disabilities is Eugenics

...Annotated Bibliography s Prenatal testing to detect genetic anomalies has become part and parcel of pregnancy care in most developed nations. While many believe that these tests are a great advancement in both science and medicine, others believe that this is another form of Eugenics. First of all, this practice takes away the right to life. The message being passed across is that it is far much better not to exist than to have any form of disability. It is also a form of abortion. Taking away innocent human life is murder and should not be tolerated. Furthermore, this practice marginalizes people with disabilities. It makes them feel worthless and less human beings. There are also many risks that mothers face when undergoing these tests...
