Software Testing
Software Testing is a method to check whether the actual software product matches expected requirements and to ensure that software product is Defect free. It involves execution of software/system components using manual or automated tools to evaluate one or more properties of interest. The purpose of software testing is to preventing bugs, reducing development costs and improving performance.
Types of Software Testing
There are many different types of software tests, each with specific objectives and strategies:
Acceptance testing: Verifying whether the whole system works as intended.
Integration testing: Ensuring that software components or functions operate together.
Unit testing: Validating that each software unit performs as expected. A unit is the smallest testable component of an application.
Functional testing: Checking functions by emulating business scenarios, based on functional requirements. Black-box testing is a common way to verify functions.
Performance testing: Testing how the software performs under different workloads. Load testing, for example, is used to evaluate performance under real-life load conditions.
Regression testing: Checking whether new features break or degrade functionality. Sanity testing can be used to verify menus, functions and commands at the surface level, when there is no time for a full regression test.
Stress testing: Testing how much strain the system can take before it fails. Considered to be a type of non-functional testing.
Usability testing: Validating how well a customer can use a system or web application to complete a task.
Advantages of Software Testing
Satisfaction of the customer.
Improves the quality of the software.
Helps in saving money.
Enhancing the development process.
Easy while adding new features.
Determining the performance of the software.
Disadvantages of Software Testing
Most testing types are time-consuming due to executing tests continuously. Thus, the failing tests should repeatedly run until fixing all the issues.
Lack of experienced software and QA testers who are aware of testing techniques.
The software testing team requires many members.
Increases the cost of the software and the budget.
Enhances the scope and increases the duration of the software development life cycle (SDLC).
Many test management systems are expensive or clunky.
