Introduction and Importance
Software development companies dedicate a substantial amount of resources and manpower for the development of applications according to requirements specified by enterprises or individuals. However, subsequent to development of such applications/software, companies are required to ensure that such software/applications perform in accordance with the client's requirements. To ensure that any and all bugs in the software are identified prior to the deployment, various testing procedures are implemented by the IT industry. The importance of testing is directly related to the ability of software to measure up to its potential. If the new software is unable to perform the task it was designed for, the client might face severe losses due to stoppage of work and also adversely affect the business of the software development company. The scope of these testing procedures is to facilitate identification of a problem in the software, fixing of such problems is not within in the scope of software testing. Some of the leading testing methodologies implemented by companies in the IT industry include General Testing, Load Testing, Functional Testing and Regression Testing.
General Testing
This refers to the general tests carried out on software/applications to ensure the functionality of newly developed software. Some of the common tests included in general testing as part of standard Quality Assurance testing procedures are web performance testing and usability testing among others. The web performance testing procedure is mostly engaged in evaluating the online performance of a web-based software application or a website. Usability testing is a mainly subjective approach, which ensures that the software is capable of being utilized effectively in a given set of circumstances. The purpose of general testing is mainly to identify the general operating capability of the software/application being tested to help developers determine some of the areas of improvement for the software. A software development company usually performs general testing of software/applications along with other more advanced tests to ensure that the software conforms to the pre-defined operational capabilities specified by the client/user group.
Load Testing
In case of load testing, the procedure simulates operating conditions of the software/application during periods of higher/normal load to gauge the effect of such changes on the functioning of the software/application. Load testing is not the same as stress testing, because load testing checks the operational capabilities in case of both normal load and high load conditions, while stress testing attempts to induce errors in normal operations by using increased system load. Load testing is considered to be a type of non-functional testing, which is undertaken by software development companies to gauge the multi-user support capabilities of the application.
Though load testing is a commonly employed practice in the software industry, its specific goals are widely disputed and the term is often utilized in conjunctions with volume testing, reliability testing, software performance testing and concurrency testing. By using load testing, developers can attempt to determine the reason for slow performance of software. The common reasons for such slow response commonly include load balancing between multiple servers, client-side processing, network congestion/latency, available database service and/or bugs in the application server(s) or software. The use of load testing is recommended for software/applications, which are subjected to SLA (service level agreement) for ensuring that the software is capable of supporting multiple users. As the procedure simulates an increase in system load by using multiple virtual users, various software are currently available to carry out load testing. Some of the leading load-testing tools used by developers globally are IBM Rational Performance Tester, Apache JMeter, LoadRunner etc. Additionally, a load testing tool commonly favored by software testing companies in India is available as part of the Visual Studio Ultimate Edition of Microsoft.
Functional Testing
This type of testing is a type of black-box testing based on the specifications of the software components being tested. The functions of specific components of the software are feeding inputs and checking the output thus obtained. In functional testing, the internal structure of the program is seldom considered hence, it is classified as a type of black-box testing. The key steps involved in functional testing include identification of functions, which the software is expected to perform, creation of input data according to specifications of the identified functions, determining output based on the specifications of those functions, executing the test scenario followed by comparison of the obtained output vs. the expected output. Functional testing is not the same as system testing as system testing involves validation of a program in comparison to the published system or user requirements, whereas, functional testing is carried out by checking a program with respect to established specifications and available design documents for the software/applications.
Regression Testing
This refers to any type of software testing, which attempts to identify bugs, which are present in either the functional or the non-functional areas of a system subsequent to making modifications such as configuration and patch changes. The aim is to ensure that the use of a patch or upgrade does not lead to the introduction of a new bug into the existing system. Additionally, regression testing helps ensure that the changes in one section of the software do not induce changes in another part of the software's code. Some of the commonly applied methods include checking for alterations in program operation and the search of any previously fixed bugs, which had re-emerged subsequent to introduction of the new code. Fixed bugs in software often re-emerge and regression testing is one of the leading methods to ensure that such re-emergence is identified and easily controlled before any lasting damage occurs. Software development companies repeatedly perform these activities on software/applications after any change in coding to ensure that the functionality of the application is unimpaired. Such repetitive testing is usually automated by using an external tool such as Bamboo, TeamCity, Jenkins, Hudson, Tinderbox or BuildBot. This type of testing is generally performed by the QA team in case of leading software development companies, however, smaller companies are often engaged in outsourcing such services to companies specializing in the field of software QA and testing.
What's Next?
As new technologies emerge, more testing procedures are being developed and implemented by organizations all over the world to ensure that new software perform according to their requirements and specifications even when stress or when additional functionality is introduced into the software. The emerging testing solutions, which are powered by new technology, are designed to reduce the time and resources required for testing in order to streamline the quality control / quality assurance services associated with software development. Some additional types of testing, which are currently used in the software industry are white box, system, non-functional, acceptance and integration testing. Each of these testing was developed to identify and resolve application/software limitations in a specific set of conditions; hence they are useful for software testing carried out in case of specific quality assurance and testing procedures.
