Software Development Life Cycle: Testing

Software testing is an independent investigation carried out in order to give concerned stakeholders accurate information on the quality of a particular software program or service under test. It helps ensure that a software system meets its objectives while meeting user expectations. This process involves testing the entire system or parts of it under various scenarios and using various criteria to evaluate whether the software is robust, readable, efficient and free from errors and bugs. Stakeholders can evaluate the software's performance by running it under various conditions and gathering relevant results. They can rely on the results to decide whether they should implement the software or not.

The testing procedure involves human supervision as well as interaction with the system or software in question. It is used in order to identify possible human errors, user errors, hardware problems and failures, usability of the software, speed, functional capability, security and much more. Some of these aspects are very sensitive and must be addressed adequately during the software development process. This is why manual testing is not used during the entire development process.

Manual testing has its disadvantages; firstly, it may be slow and may require too much work on the part of the testers and developers, resulting in less productivity on the whole. Secondly, manual testing can easily miss bugs and defects which already exist in the software application. Testing software applications manually without automation makes the software development process a lengthy one and may also prove to be unsuccessful. In addition, manual testing cannot easily distinguish between potential errors and defects that exist in the product.

On the other hand, automated testing addresses these shortcomings. It not only helps detect and correct defects and mistakes but also ensures maximum flexibility for future changes. Through automated software testing, even hardware and software components can be tested without manual intervention. Software testing automation also helps software testers to quickly pinpoint the exact location of defects and enables them to repair or eliminate them as soon as possible.

As previously stated, scheduling a user acceptance test enables software developers and testers to identify and locate any defects or errors in the product before they are released for use. Through this, software applications become more secure, stable, and safe for use. Since defects are found and repaired before users get the chance to experience their functionality, quality products always maintain their initial appeal and credibility. Software testing thus proves to be a crucial element in the software development process.

Apart from detecting and fixing defects and mistakes, software testing methods also ensure the effectiveness of the product. These methods differ in two different ways: dynamic testing methods involve creating and testing applications that run continuously while static testing involves testing applications that have to be deployed at specific times. Both of these testing methods are essential for software quality assurance.

Another difference between these two methods is the level of user experience testers are permitted to have. Dynamic testing permits testers to have full control over the program, whereas static testing requires testers to follow a specific time schedule. This schedule largely determines how often the software is tested. In contrast to the testing of security testing, user experience testing entails a more active participation from users in order to pinpoint and correct bugs. Furthermore, while testing software applications for security, it is also important for testers to consider how the program will be used by a number of different people, including developers, IT professionals, and end-users.

In order to have a successful and efficient software development life cycle, all the parties involved in the project need to work together and communicate effectively with a view toward finding and resolving any issues and problems facing the software during its implementation and early usage. A team that is capable of implementing software testing and can solve problems quickly will prove to be beneficial in this process. However, if you lack the knowledge and expertise in this area, then it would be better to outsource this task to a professional software testing company. With the help of a reliable and experienced tester, software developers can save money, time, effort and learn a lot more about their software development projects.
