Some people believe that software testing must be done at the end of software development, as a final stage. However, it is important to note that testing must be done at all stages of development. It must be integrated into it and must be a continual process throughout. For example, once requirements have been gathered, design must be created and implemented. Once each module is developed, it should be tested immediately for any bugs or defects. Or if prototypes are to be delivered to the customer, after each delivery, the software must be tested.
Software testing should not be left to end; after all the modules of a project have been developed. How and when testing is carried out also depends on customer requirements and desired results, the Project Manger’s way of working, and the Project Lifecycle model.
Software testing is still considered to be an art because there is still limited understanding of it. The reason for this complexity of software testing is that there are so many testing principles, techniques and tools available that can be used to carry out this critical activity. One must know which ones are most suitable in accordance with the software being developed.
Software testing tools include source, embedded, functional, performance, java, link and HTML, API, requirements management, security and many other test tools (Applied Testing and Technology, 2009). Software testing techniques vary as the software travels through its stages of development lifecycle. However, software testing techniques can be roughly divided into unit testing, integration testing, system testing and user acceptance testing (Luo, 2009). The general goal of all these testing tools and techniques is to produce a high quality software that meets customer requirements, by developing it in controlled circumstances (Luo, 2009).

Software Engineering Testing tools

...or unwittingly misused, it is essential for professionals with a good knowledge of the vulnerabilities of these features and how software can be protected to have an active role in the analysis of such misuse and unreliability. Software engineering involves the use of tools, processes and techniques that will enable the software engineer to address various programming and development issues in various phases of the software development life cycle (SDLC). Testing of software enables the evaluation of the capabilities and attributes of systems or program or in order to ensure that the...

Quality Management Tools & Techniques

...? Quality Management Tools and Techniques Quality management tools and techniques Quality management tools and techniques used in data analysis. The X-bar and R (range) chart is a pair of control charts that are utilized in processes that have a subgroup size of two or more. In the standard chart for variables data, R charts and X-bar charts help to determine if a particular process is stable and predictable. According to functionality, the X-bar chart shows how the averages or mean changes over time while the R chart outlines how a range of subgroups changes over time. In addition, it is also used in the monitoring of...

Techniques & Tools

...Techniques and Tools In making decisions, zeroing on what the important things are versus those which are secondary or not important at all, requires tools and techniques. Together these tools enable a decision-maker to arrive at a wise decision. These tools separately involve important elements such as time or the urgency element, the inter-connecting factors or parts that gives an analytical picture of a situation and the systematic process to follow in arriving at a decision. The first tool is the urgency-criticality matrix. When a situation arises that requires solution, many choices on what to do...

Web Software Testing

...the quality of web applications is testing which is attracting more and more attentions from the researchers and quality assurance professionals. In addition, the typical techniques are adapting the traditional testing methods for web applications as well, for web applications belong to the software products and have some commonness with the traditional software. But traditional testing methods are not enough to confirm the quality of web applications (Xu, Xu, & Jiang, 2005; Sprenkle, Gibson, Sampath, & Pollock, 2005; Qian, Miao, & Zeng, 2007). The structure of the paper is as follows: next section presents various important types of...

Hackers Tools and Techniques

...Hackers Tools and Techniques Hacker tactics, tools and techniques are constantly evolving and at a much faster pace than organization’s can learn to protect sensitive data (SearchSecurity, 2009). Hacking can take place in different forms such as spoofing, smurfing and other Denial of Services (DoS) attacks. The tools and techniques also vary from password cracking (Shimonski, 2002) to finding access vulnerabilities (Sun Microsystems, 2002). The banking and financial services industry has been target of cyber attacks and individual online accounts have become pervasive (Acohido, 2010). Hackers gain access to vulnerabilities through...

A topic on software testing

...hardware structures and requirements, he argues that better tools, which can perform tests efficiently along with better analysis and reporting, are the need of the hour. In other words, software testing must also evolve over time in tune with changing requirements and should be capable of adapting to more complex scenarios. This paper comprises a research proposal aimed at determining the quality of software testing in embedded systems. In addition to a comprehensive literature review, this proposal outlines the various objectives and subject areas that will guide the research process. All techniques...

Software Testing

...method of testing software (Basili and Selby, 1987). Scope According to Gelperin and Hetzel (1988), we are going to deal with phase models and life cycle models. In the phase models, we have a demonstration and destruction phases. Demonstration ensures that the software satisfies all its specifications. Destruction involves detection of the implemented faults that may lead to errors during the software functioning. In the life cycle models, we have an evaluation and the prevention stages. In the evaluation, one detects requirements, design and implements faults. In prevention, requirements, design and implementation faults are prevented. Review of...

Software testing

...to select a feasible technique which is available at the time of test so that the required information about the application can be obtained (Savenkov, 2008). The test does not only give objective view on the risks but also on the quality of that given product that is being developed. According to Meyer (2008), software testing can be done immediately an executable application is available. In most instances, the approach which is being used in the software development process will dictate when the testing will be done and how it will be carried out. When the phased process is being used by the developers, then...
