Software testing verifies that the system meets the different requirements including, functional, performance, reliability, security, usability and so on. This verification is done to ensure that we are building the system right and it is what the user really expects. Apart from helping make decisions, the information from software testing helps with risk management.
Software testing contributes to improving the quality of the product. Finding defects / bugs is one of the purposes of software testing, it is not the sole purpose. Quality improvements help the organization to reduce post release costs of support and service, while generating customer good will that could translate into greater revenue opportunities.
The objectives of Software testing.
Finding defects which may get created by the programmer while developing the software.
Gaining confidence in and providing information about the level of quality.
To prevent defects.
To ensure that it satisfies the BRS that is Business Requirement Specification and SRS that is System Requirement Specifications.
To gain the confidence of the customers by providing them a quality product.
When to start testing activities?
Testing activities should be started as soon as possible to reduce the time and cost to rework and produce software that is hassle and bug-free so that it can be delivered within the agreed timeline to the valued customer. However, in SDLC (Software Development Life Cycle), testing can begin from the Requirements Gathering phase and continued until the software is fault-free and out there in production. It also depends on the development model that is being used. For instance, in the Waterfall model, testing begins from the testing phase, however, in the V-model, testing is done parallel to the development phase.
Software testing is performed to verify software functions according to the expectations defined by requirements/specifications. The overall objective is actually not to find every software bug that exists but to uncover situations that could be an unpleasant experience for the customer, usability, and maintenance. Testing is what in a way we owe to our users and ourselves if we want to deliver the best possible application.
The existence of numerous devices, browsers, and operating systems out there, each with its own distinct properties make it crucial to ascertain that all the users are receiving the same quality solutions. Each user accesses an application in their own unique (sometimes unconventional) ways, which can be hard for someone to contemplate while developing. It’s also worth remembering that something that works for a handful of users may not work when hundreds of users are using it.
When it comes to delivering excellent code with exceptional programming and designing standards, unit tests are easy to develop and that also makes them inexpensive. Unit test cases make it possible to fix most of the errors, which are normally difficult to find and fix at the testing stage, thanks to the simplicity and number of issues that they are able to detect.
The method of making sure quality is divided equally over all the programming stages can guarantee a more effective and efficient product.
Why do we need testing? Is this even a question?
