Quality assurance engineers are required to do software testing. They test the software fully to check the quality and performance. The mission is that the end user must be able to use their software without any hassle. There are various testing methodology in software testing. The Methodologies are named – Functional Testing and Non-Functional Testing.
Some functional tests are Unit Testing, Integration Testing, Interface Testing etc. Some Non-Functional Testing are performance testing, security, load testing, etc. Towards the end of this article, you will know all software testing methodologies. Please read the article fully to learn about it.
What Is Testing Methodology in Software Testing?
The developers, software engineers, and software quality assurance engineers initiate what is testing methodology in software testing. However, only quality assurance engineers do quality checks once the software is fully developed. There are two main testing methodologies in software testing: (1) Functional Testing and (2) Non-functional Testing. I have written the definition of both QA processes and methodologies through the points below:
Functional Testing:
- Functional testing checks if software features are working according to software requirements. It ensures that each feature is working as expected
- Functional testing also means checking the API, database, and functionality
- It also means to make sure that software can be used by all other devices and configuration
Non-Functional Testing:
- Non-functional testing focuses on the product’s performance. It ensures that the product can meet the customer’s expectations
- It also focuses on the dependability and usability of software
- Non-functional testing also does the load test of the software
These were the definitions of non-functional testing and functional testing. Further, you will learn about the QA testing types.
Purpose of Testing in Software Testing Methodologies
There are multiple purposes for software testing guidelines. A software quality assurance tester does software testing to ensure the product’s best performance. Here are some purposes of testing in what is testing methodology in software testing:
- The purpose is to make the product meet with market’s high-quality standards
- A quality assurance engineer must make the product reliable. It reduces customer support costs
- It makes the product bug-free. As a result, the end user can use the product without any complaints
- The target is to make the product fully developed until it becomes good enough to deliver to customers
Which Methodology Is Used to Perform Maintenance Testing?
Breadth and depth test is used to perform maintenance testing. This testing can be done by new software testing engineers and skilled testing engineers. However, here I have described the testing in more detail:
In breadth testing: The in breadth testing does the functional testing of the whole software. It does not necessarily check the product’s features in detail.
In-depth testing: The in-depth testing does testing of the software in full detail. It will ensure the software’s quality by checking the product’s features. In this process, the defects are found in the software then the problems become fixed.
Which Of The Following Testing Is Performed By User?
Beta testing is performed by the user. This testing is called user acceptance testing. This is performed by a user even before its official release. This is one of the crucial software testing strategies. When users use the software, they experience the software’s overall performance.
Then they will let you know the software’s faults and defects. They will also let you know which area of the software needs improvement. The beta testing helps the software uncover bugs and problems. Hence, the process must be carried out to ensure better software.
There are two types of beta testing- Open and closed. The open beta testing is for everyone. They can try out the beta application to give feedback. They are given a specific system to submit the feedback to the developer. That’s how the beta application is tested by the user.
Another kind of testing focuses on specific users. The closed testing is for the users who are paid to test the beta version. Then they give feedback to the developer of their test. That’s how the process of two types of beta testing is done. Later, product managers collect all feedback from the beta tester.
Then, the ideas, and suggestions are taken from the tester for better future release. It would help to find out the missing features that should be added. It could impact the buying choice of users.
Moreover, it will also make better software applications for the user. As the software is tested by a larger group of people, the feedback helps a lot to improve. Hence, it gives better and perfect software applications as a result for the users.
Types of Functional Testing in Software Testing
There are types of functional testing in software testing methodologies. These methodologies help the software to give better performance and reliability. Each of the what is testing methodologies in software testing works in different sectors.
Many types of functional testing have different aspects of handling the software testing. Here I have discussed the types of functional QA testing in software testing through the points below:
1. Unit Testing
Unit testing in software testing focuses on functional units of code. It is the smallest part of the software that is made in individual units. When you write codes, you see whether the code is working properly or not. It helps you to identify the problems and defects existing in the software.
2. Integration Testing
Integration testing focuses on the modules that are tested as a group. This testing method makes sure that the whole software is working properly. It will ensure the software’s components work together as one. The problems or defects would be identified during the process and fixed.
3. Interface Testing
Interface testing focuses on ensuring that the two different software can interact together without any hurdle. It will let you find out the data mismatch between different software or software to hardware. It gives you scope to improve the problem accordingly.
4. System Testing
System testing focuses on examining the fully integrated software system. It will ensure that the software’s overall performance is okay. Moreover, it will help you to identify if the software is working as designed or not. It will help you to verify the system meets its specified requirements.
5. Regression Testing
Regression testing focuses on the update after a new code is introduced to the software. It will help to identify that the new update has no errors or bugs in the processing. It helps to recognize the problem after the potential mistakes that might happen during modification.
6. Smoke Testing
Smoke test refers to testing that is done at the initial stage to check for faults. It also lets you know whether the software is testable or not. It will ensure that the software meets the basic requirements of functionality. You may identify this with another name called “Sanity testing”.
7. Static Testing
Static testing is the method where the software is tested without applying codes to the software system. This testing found bugs in the software at the early stage. It also helps to improve the software quality and fix problems at a lower cost.
8. API Testing
The API testing ensures that the software application is working as expected. It will make sure that the interface of the application is compatible with its expected functionality. This testing will help the software to be more reliable and give the best performance to the user.
9. Compatibility Testing
The compatibility testing will make sure that your software application can be used on different hardware programs and operating systems properly. If there are any defects or faults during this process, then it will be fixed accordingly. It will also make sure that the software is working fine with previous versions.
10. Usability Testing
The usability testing mostly focuses on the user’s experience. It will observe how the software is working for the user. This testing will evaluate the product by having it tested. It must make sure that the system is working smoothly and comfortably.
