Software testing is a process, to evaluate the functionality of a software application with an intent to find whether the developed software met the specified requirements or not and to identify the defects to ensure that the product is defect-free in order to produce a quality product. The standard definition, testing types such as manual testing and automation testing, testing methods, testing approaches, and types of black-box testing.
According to ANSI/IEEE 1059 standard – A process of analyzing a software item to detect the differences between existing and required conditions (i.e., defects) and to evaluate the features of the software item.
Software testing is the process of verifying a system with the purpose of identifying any errors, gaps or missing requirement versus the actual requirement. Software testing is broadly categorised into two types – functional testing and non-functional testing.
When to start test activities: Testing should be started as early as possible to reduce the cost and time to rework and produce software that is bug-free so that it can be delivered to the client. However, in Software Development Life Cycle (SDLC), testing can be started from the Requirements Gathering phase and continued till the software is out there in productions. It also depends on the development model that is being used. For example, in the Waterfall model, testing starts from the testing phase which is quite below in the tree,; but in the V-model, testing is performed parallel to the development phase.
When to stop test activities: An application can never be 100% bug-free. So to ascertain when one can stop testing is difficult. However, the following things are kept in mind while stopping the test activities:
• Testing deadlines
• Completion of test case execution cycle
• Completion of functional testing and code coverage to an agreed limit
• No high-priority bug is found and the rate of finding bug declines after a certain level
• Management decision A software test process consists of the activities
What if there is no Software Testing in the Software Development Process
As per the current trend, due to constant change and development in digitization, our lives are improving in all areas. The way we work is also changed.
For instance, we access our bank online, we do shopping online, we order food online, and many more. We rely on software and systems.
What if these systems turn out to be defective. We all know that one small bug shows a huge impact on business in terms of financial loss and goodwill.To deliver a quality product, we need to have tested in the Software Development Process.
In software testing, functional testing is a practice that delivers huge benefits to the development process. When done properly, it increases communication between analysts, developers, and testers. The progress of the entire project is objectively visible at any point in time to management by examining the passing (and failing) functional tests. Eventually, the speed of development increases because well-communicated requirements result in less re-work. The tests also drive a more modular architecture with subsystems that have clear responsibilities.
Importance of Software Testing
It’s common for many startups to skip testing. They might say that their budget is the reason why they overlook such an important step. They think it would lead to no major consequences. And for that, testing the product for bugs is a must. Similarly, established organizations need to maintain their client base and their impression. So they have to ensure the delivery of flawless products to the end-user.
The importance of software testing and quality assurance is of high value in a software development cycle. Both of the processes refine the whole process and ensure superior quality to the product. Also, it reduces maintenance costs and provides better usability and enhanced functionality. When software testing signs and push the individual components, quality assurance attests to the product- Fit for the purpose.
