Software Testing

What Is Software Testing?

Software Testing involves the evaluation and comparison of actual results with expected ones to ensure that software systems are defect-free; to identify errors, gaps, or missing requirements as compared to the actual requirements.

Software quality assurance (SQA) is a process that ensures that developed software meets and complies with defined or standardized quality specifications. SQA is an ongoing process within the software development life cycle (SDLC) that routinely checks the developed software to ensure it meets desired quality measures.

SQA encompasses the entire software development process, which includes processes such as requirements definition, software design, coding, source code control, code reviews, software configuration management, testing, release management, and product integration. SQA is organized into goals, commitments, abilities, activities, measurements, and verifications.

Types Of Software Testing

Functional Testing

Functional testing is a category of software testing in which a software system is tested against the requirements by putting an input and evaluating the output. It ensures that the functions of the software application are in line with the requirements. Many types fall under this category. Few of them are as follows:

Unit Testing: In unit testing, each unit of a software system is tested individually to ensure the performance of every module of software.

Integration Testing: It is a type of functional testing where software modules are logically integrated and tested as a group. The primary function is to check data communication amongst these modules.

System Testing: System testing is performed to validate a completed and integrated software so as to check if the software is compliant with the assigned requirements.

User Acceptance Testing: UAT verifies whether the software solution works for the user or not. This is very important because users are the people who will finally use your software.

Non-functional Testing

The purpose of non-functional testing is to check the readiness of an application according to non-functional parameters. The non-functional aspects tested under this type of testing are performance, endurance, volume, scalability, usability, and so on.

Regression Testing: A type of software testing which is done during the development phase of software systems for all functionalities and features in detail.

Compatibility Testing: There are many platforms on which a software can be run. Compatibility testing is performed to check if the software is capable enough to be run on different hardware, mobile or computer devices, operating systems etc. It basically checks the capability of a software under different working environments.
