Testing is an integral part of any successful software project. The types of software testing depend on various factors, including project requirements, budget, timeline, expertise, and suitability. The different Types of software testing are the key role where the tester determines the right testing for the apps. Functional testing and non- functional testing are the two kinds of testing performed by the QA or Software Tester.

Functional Testing

Functional Testing is defined as a type of testing which verifies that each function of the software application operates in conformance with the requirement specification. The functional testing focuses on manual as well as automation testing.

The different Types of Functional Testing include :

Unit Testing

It is a level of software testing where individual units/ components of a software are tested. The purpose is to validate that each unit of the software performs as designed. A unit is the smallest testable part of any software. It usually has one or a few inputs and usually a single output.

Integration Testing

It is a level of software testing where individual units are combined and tested as a group. The purpose of this level of testing is to expose faults in the interaction between integrated units.

System Testing

It is a level of software testing where a complete and integrated software is tested. The purpose of this test is to evaluate the system’s compliance with the specified requirements.

Interface Testing

When an application or a software or a website is developed, then there are several components of it. Those components can be server, database etc. The connection which integrates and facilitates the communication between these components is termed as an Interface. It verifies that communication between the systems are done correctly.

Regression Testing

Regression testing is a crucial stage for the product & very useful for the developers to identify the stability of the product with the changing requirements. Regression testing is a testing that is done to verify that a code change in the software does not impact the existing functionality of the product.

User Acceptance Testing

Acceptance Testing is a level of software testing where a system is tested for acceptability. The purpose of this test is to evaluate the system’s compliance with the business requirements and assess whether it is acceptable for delivery.

Non-Functional Testing

There are a bunch of software testing types which differentiate the job work for the QA while testing the apps. It is a testing to determine the performance of the system to major the measure, validate or verify quality attribute of the system.

The different Types of Non-Functional Testing are :

Documentation Testing

Documentation testing helps to estimate testing efforts required and test coverage. Software documentation includes test plan, test cases, and requirements section.

Installation Testing

Installation testing is a type of quality assurance work in the software industry that converges on what customers will need to do to install and set up the new software successfully. The testing process may involve full, partial or upgrades install/uninstall processes.

Performance Testing

Performance Testing is defined as a type of software testing to ensure software applications will perform well under their expected workload.

Reliability Testing

Reliability testing assures that the product is fault free and is reliable for its intended purpose. It is about exercising an application so that failures are discovered before the system deployed.

Security Testing

Security testing is a variant of software testing which ensures that system and applications in an organization are free from loopholes. Security testing is about to find all possible weaknesses of the system which might result in a loss of information at the hands of the employees.
