What is the Life Cycle of a Software?

Software Testing Life cycle(STL) is essentially a series of activities conducted within the testing process to achieve software quality objectives. STL includes both validation and verification activities. Validation involves verifying the data obtained during validation, whereas verification aims at checking the results of previous validated results. Both these activities help developers verify the software’s functionality as well as its adherence to certain quality standards.

What Is SDLC (Software Development Life Cycle)

Lifestyle refers to the process used in testing software. During this phase, test candidates are given an outline of the testing job and given some basic instructions on how to carry out their tasks. Test candidates are also taught how to perform their testing activities. During this stage, the testers are assigned some common testing tasks. These tasks include testing user interfaces, determining the functionality of the software, testing the behavior of the software in different environments, etc.

The second stage of the life cycle is the specification phase, which requires testing candidates to create specifications or documents that contain details about the expected functionalities of the software. Specifications may cover the features of the software, user interfaces, etc.

Testing is done through various methods such as unit testing, integration testing, etc. The testing methodology selected depends upon the software testing goals. For example, Unit testing may be used for software components that have one and the same function. Integration testing, on the other hand, can be utilized for software components that are required to interact with each other.

Software Development Life Cycle: Phases and Models

Functional testing is the testing of a whole system, i.e., testing the entire software system. During this stage, all the modules of the software system are tested to determine the complete functionality of the software. This is usually performed by using software engineering techniques such as unit testing, integration, design testing, etc. Design testing is commonly used when the software is intended to act as a control system in order to perform specific business functions.

The third stage of testing is the acceptance testing stage wherein test candidates are expected to pass tests to establish that the software has passed all the requirements set by the user. The software is then accepted to be released for production use. Release testing is usually done after software testing is done and it is done by testing the software for its compatibility with a number of operating systems and configurations.

Software testing is usually conducted by teams consisting of software testers, programmers and testers who are responsible for verifying the software’s functionality and conformance to various industry standards. These individuals may be from different disciplines such as testers from software development, hardware manufacturers, system analysts, testers of database software, testers of application software and testers of web-based software. There are also software testing companies that specialize in particular types of software such as database software, database application software, web-based applications, etc.

The Software Development Life Cycle: Benefits, Stages

The most important things that you must consider while implementing software testing is the software’s usability. The purpose of testing is to determine whether the software meets its customer’s requirements and functions as per their expectation.

Test suites is created to test a software’s functionality and conformance to specific industry standards. These test suites are developed according to the type of software that you are planning to sell. It includes an initial specification of the software system followed by the software testing. Software testing helps to ensure the quality of the software. By using software testing, you can easily detect any type of defects in the software program.

The software that you plan to sell should also include documentation and user support features so that buyers will be able to understand and use the software easily and effectively. If the software package includes user manual, it should be properly maintained by incorporating test scripts to make sure that the software functions as expected.

The software testing process also includes checking the performance of the software based on the expectations of the software’s users. These checks include testing both its functional and non-functional aspects. Users are asked to install the software and use it for a limited period to determine whether they can use the software easily and efficiently.

If the test results are found satisfactory then the software is released to the market with the assurance of being able to perform the tasks that were expected of it. Thus, the software’s life cycle is a critical part of software testing.
