Types of Software Testing

In this tutorial you will learn about the Types of Software Testing and its application with practical example.

Types of Software Testing

Different types of software testing are available that help detects different areas of the software. Each of these types of testing has its set of advantages, features, and disadvantages as well. The underlying guide covers all types of software testing tools. There are two different types of software testing models i.e.

  • Functional Testing
  • Non-Functional Testing

Functional Testing

These are further classified into their sub-types.

First, let’s see the types of Functional Testing.

  1. Unit Testing

It is a type of software testing that is done on an individual unit or component. It is performed to test its corrections. Unit testing is done by the developers during the application development phase. Each unit is considered as a method, function, procedure, or object. It is further classified into two types White box testing and Gorilla Testing

  1. Integration Testing

It is a type of software testing where two or more modules of an application are integrated and tested as a whole. This test focuses on finding the defects in the interface, communication, and data flow among the modules. Two approaches i.e. Top-down or Bottom-up approach is used while integrating modules into the whole system.

  1. System Testing

In this type of testing the tester evaluates the system and then decides the precise testing to be implemented. But how many testing types are in this software testing? All in all, there are six types of different system testing. These tests include,

  • End to End Testing: Test the complete environment of the system.
  • Black Box Testing: Test performed without knowing the internal structure.
  • Smoke Testing: To verify the critical and basic functionality of the system.
  • Sanity Testing: To verify newly added functionality or bug fixes.
  • Happy Path Testing: To test the application for the positive flow.
  • Monkey Testing: To check the system for crashes for random data inputs.
  1. Acceptance Testing

It is a type of testing where the system is tested for real-time business scenarios including customers, clients, business, etc. The client accepts the software only if the features and functionalities work as expected. It’s the last phase of testing which gives a green signal for the production of the software. It is further divided into three types i.e. Alpha Testing, Beta Testing, Operational Acceptance Testing.

Non-Functional Testing

Further, there are various types of software testing in Non-Functional Testing.

  1. Security Testing

A special test is performed by a special team to check if any hacking method can penetrate the system and affect its functionality.

  1. Performance Testing

It is the test of the application’s stability and performance along with its response time which is tested by applying load on the software.

  1. Usability Testing

It is beneficial in testing an application from the user’s perspective. Usability testing helps check the feel and user-friendliness of the software.

  1. Compatibility Testing

It tests the software for its performance in different environments, web servers, hardware, and network ecosystem.


The above-mentioned guide discusses the different types of software testing in brief. Although the list can be extended depending on the type of software, functionalities it offers, its applications, and much more. And hence the list of various types of software testing tools is ongoing. Besides, it’s not that all types of tests are applied to a single software. Each software passes through different tests to give different results, detect defects, and identify bugs.

In this tutorial we have learn about the Types of Software Testing and its application with practical example. I hope you will like this tutorial.
