Software Testing Methodologies - Learn the Methods & Tools

Introduction


In today's quickly evolving technological sector, remaining ahead of your competitors while providing the best quality software consistently are the two differentiators that make an app-first company successful. These testing processes are used to make sure that you deliver a well-tested product in the least time possible and keep up with the lightning-quick software development lifecycle. So if you are planning to empower your business with Next-gen applications by implementing the best software testing methodologies and tools, then hire a dedicated team of QA engineers from a top-notch software testing company and get the desired outcomes.


In this post, we’re going to discuss various software testing methodologies and tools that are used to test the entire software and make it error-free. So without any further ado, let’s get started!


What are Software Testing Methodologies?


Software testing methodologies include various types of approaches and different ways of ensuring that software is thoroughly tested or not. These methodologies are considered a set of testing mechanisms used in the software testing life cycle from unit testing to system testing. Such methodologies encompass everything from individual modules and integration testing of a complete system to specialized forms of testing like performance and security.


We all are aware of the fact that software testing cannot be neglected as it is an important part of the software development process. With usability, security, and compatibility, a product can be tested by implementing the best testing processes.


Now you must be wondering how to choose the right software testing methodology for your software. Isn’t it? So let us now proceed ahead and find out what are the benefits offered by various software testing methodologies.


Functional Testing


1. Unit Testing


Unit testing is a part of software testing methodology which is an essential part of individual product components that creates an application. Do you know what to write the tests for when it comes to unit testing? Software developers are the one who writes the test cases in a test-driven-development methodology before creating the module because it is included in the same programming language where the modules are available. Make sure you are not ignoring this testing method as it helps you to detect bugs at an early stage.


2. Integration Testing


After performing unit testing, Integration testing with other units is done to create modules of components that are particularly designed to perform integration testing to make sure that the entire segment of your product works exactly the same as desired. It is an important part of the testing methodology as it tests various modules that are successfully unit-tested when integrated together to perform a set of tasks.


3. System Testing


System testing is basically a black box testing methodology that is a part of functional  testing that allows software testers to test the entire system and check for errors and bugs. Basically, it is used to evaluate the integrated system and make sure that it meets specified requirements listed by the clients. It is carried out by interfacing the software and hardware components of the system and then it is tested as a whole, where the user-expected working conditions are checked.


4. Acceptance Testing


The acceptance testing is the last phase of functional testing which is called the final stage which ensures that all the project requirements are met. The customers have tested the system to make sure that it functions as expected and all its requirements are defined clearly. In acceptance testing, you need to test the product both internally and externally, and for this, you need a resourceful team of QA testers having enough knowledge and expertise about various testing techniques. Beta testing is the only way to get real customer feedback and address any final usability concerns.


Non-functional Testing


1. Performance testing


Performance testing is a type of non-functional testing that is used to check how your app will behave under various conditions and check whether the system meets the non-functional requirement identified in the SRS document or not. The aim of this testing technique is to test its stability in real user situations. Performance testing is broken down into four major segments which include load testing, stress testing, endurance testing, and spike testing.


2. Security testing


This non-functional type of testing technique helps you to determine whether the information and data in your system are safe or not. Security is the main concern for all and it should be tested thoroughly as the cyber-crime attacks are increasing and the awareness of risks associated with software vulnerabilities needs to be developed as the desired business functionality. Its main aim is to find the loopholes and security risks in the system so that no unauthorized access can be granted and the chances of loss of information reduce as it results in probing the application for weaknesses. The six basic principles of security testing are integrity, availability, confidentiality, non-repudiation, authentication, and authorization.


3. Usability testing


Usability testing is a non-functional testing methodology that allows you to measure an app's ease of use from the end-user point of view and it is also performed during the system acceptance testing stages. The ease at which users are free to access the product forms when it comes to the main testing point. Also, it is the best way to review separate functions or the system as a whole is intuitive to use. There are five main aspects of usability testing which include memorability, learnability, satisfaction, efficiency, and more.


4. Compatibility testing


Compatibility testing is a part of testing methodology which is used to gauge how a product or part of it will work in different environments. It checks whether it is compatible with all the OS, hardware platforms, mobile devices, web browsers, and other designed third-party programs. They aim to make sure that your product's functionality is supported consistently across various platforms that your end-users are expecting to use.


Final Thoughts


In closing, we would like to mention that, there are various software testing methodologies available in the market when it comes to software development. But when you consider the testing part, make sure to identify your requirements, budget, project size, and scope before anything else. If your project is small, you're sure about the scope of the project, so here you can use methods like a waterfall as it can be very beneficial. Make sure that you're addressing testing at an initial stage in your SDLC so that you can detect bugs earlier on, and enable you to integrate testing feedback into the design stages. By doing so, you can achieve better quality products and easily shift your focus towards making testing a priority. We all know that each project is unique in its own way and all have their unique requirements, so make sure to invest a good amount of time and effort in choosing the right testing methodology and then proceed ahead.
