What is Software Testing? All you need to know about Types of Testing

December 31 2019

Today’s world of technology is completely dominated by machines, and their behavior is controlled by the software powering it. Quality Assurance or Software Testing is crucial because it identifies errors or bugs from a system at the beginning.
Quality is never an accident; it is always the result of intelligent effort. Testing is an essential requirement of Software development. Software testing has different methods, types, and levels of testing.
Levels of testing include different methodologies while doing software testing.

Types of Software Testing will provide you with in-depth knowledge about the different types of Software Testing in the following sequence :
1. Functional Testing
2. Non-Functional Testing

Functional Testing
It is a type of Black-Box testing and it is based on the specification of the software that is to be tested. The Software application tested by providing input then the results are compared with the need to conforming to the functionality. It is conducted on a complete integrated system to evaluate the system’s compliance with decided specific requirements.

There are five steps that involve functional software testing.
1. The resoluteness of the functionality that the software application is meant to perform.
2. Then the test database is created on the basis of the specification of the application.
3. Get the output based on test data and specification of the application.
4. The test scenarios are written and test cases are executed.
5. The comparison between expected and actual results on the basis of executed test cases.

Unit Testing
Unit testing is performed by the developers before setup is handed over to the testing team after that they formally execute the test cases. It is not able to catch each and every bud in the testing. The unit testing works on to separate each part of the program and then show that each part is correct in terms of requirements and functionality. The execution path is impossible to evaluate in every software application.

Integration Testing
It is defined as the testing of combined parts of the application to check whether the application function correctly.
1. Bottom-up integration
2. Top-up integration

System Testing
It tests the whole system. Firstly it integrated all the components then tests to evaluate that the application meets with the specific requirements. System testing is performed by the specialized testing team. It enables us to test, verify, and validate both the application architecture and business requirements.

Regression Testing
When any change is made out in any Software application so it is possible that other areas will also be affected because of the change done. Regression testing works to verify that the fixed bud has not resulted in any other functionality of the software application. It ensures that the bugs do not affect any other functionality.

Acceptance Testing
It is the most important kind of testing. This is a testing technique which is used to determine whether the system software meets with the business requirements or not.
These are the four forms of acceptance testing:-
1. User acceptance testing
2. Business acceptance testing
3. Alpha testing
4. Beta testing

Alpha Testing
This is the testing performed by the group like independent of the design team within the company. It is the stage of final testing before the software is released to the public.

Beta Testing
This testing is also known a field testing. It is executed to the end-user site when the developer is absent. In this testing, the process developer corrects the errors when users report for occurred issues.

Conclusion:
Everyone who strives for high-quality software orders testing services before the product goes out on the market. It is not advice, it is a rule. The advice is — trust your software to professionals. Make sure the vendor of QA services has all needed devices and uses only up-to-date testing software to check your product.
