It also depends on the development model that is being used.

However in Software Development Life Cycle (SDLC), testing can be started from the Requirements Gathering phase and continued till the deployment of the software. When to Start Testing?Īn early start to testing reduces the cost and time to rework and produce error-free software that is delivered to the client. The next two sections state when testing should be started and when to end it during the SDLC. It is not possible to test the software at any time during its cycle. In most cases, the following professionals are involved in testing a system within their respective capacities −ĭifferent companies have different designations for people who test the software on the basis of their experience and knowledge such as Software Tester, Software Quality Assurance Engineer, QA Analyst, etc.

Moreover, developers also conduct testing which is called Unit Testing. In the IT industry, large companies have a team with responsibilities to evaluate the developed software in context of the given requirements. It depends on the process and the associated stakeholders of the project(s).

In simple words, testing is executing a system in order to identify any gaps, errors, or missing requirements in contrary to the actual requirements.Īccording to ANSI/IEEE 1059 standard, Testing can be defined as - A process of analyzing a software item to detect the differences between existing and required conditions (that is defects/errors/bugs) and to evaluate the features of the software item. Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not. Software Testing - Overview What is Testing?
