It is so important that half of the development of any software must be dedicated to it, as a rule of thumb. 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).

This research paper details a study about the unreliability of software engineering testing tools as a result of the misuse of these testing tools in development. Testing activities that are geared towards evaluating the capabilities and attributes of systems or programs with a view to ascertaining whether the program produces the required results will be discussed.
The company, based in Middleton, designs and develops aircraft that it then sells to commercial airlines. The scope of the company’s activities employs a lot of locals in Middleton, therefore, making it a key economic pillar of the region. Whereas Maxil Aerospace’s business has been largely successful it has been experiencing a lot of challenges in the recent past.
Similarly, the third bill followed with the fourth that stated ‘a legal action will be taken if the bill of $0.00’ were not paid ASAP. Adding up more to the story, the fifth bill came up with all the harsh statements of paying off the bill at once. With that story, the credit rating of that the organization was in the hand of that wrongly programmed computer that was doing wrong calculations.
The first tool is the urgency-criticality matrix. When a situation arises that requires solution, many choices on what to do come up. But usually, a decision-maker is pressed for time. According to a website article on time management, urgency is usually connected with a deadline and external factors while the importance of a job or task has something to do with how much time in fact one actually wants to spend with it ("Time Management - Urgent v Important" 2, 2006.) because it impact one's long-term goals.
This paper examines various testing techniques and recommends methods that would be most appropriate in the context of web service development. Finally, it demonstrates the performance of these methods in an actual business environment by applying it through a case study.
