Software Testing – Latest Methods and Approaches

Software Testing

In any software development process, the testing comes at last. No company would ever deliver the software product without doing its final testing. Software testing is an essential part of the roadmap of developing a robust and stable product. A software application may be complex or easy depending upon the platforms and devices, where it is run.

In software testing, an IT product undergoes various test cycles that test the product’s work. If the software is found working properly with no side effects in its usage, then the software is considered as a well-developed bug-free product.

Therefore, in a software testing life cycle, it is always important to test the software on all devices and platforms. However, to do so different software testing services, methodologies, and tools are needed. Basically, software testing methodologies refer to different approaches and countless ways of inspecting software such that it gives the outcomes we have thought while developing it.

In this article, we are going to talk about software testing methods and approaches.

The different types of software testing methodologies

If a software application is complex and is intended to work on various platforms & devices, then its testing would be comprehensive. For this, many robust testing methodologies are needed that fully tests the products and systems to find out if they meet their specified requirements or not. Testing methodologies comprise unit testing, integrated testing of software and the entire software system, some of them are explained below.

  • Unit Testing: In this, developers focus on every minute functional units, isolate every unit and test its functionality.
  • Integration Testing: The developers now create a mechanism where different modules of software relate to each other, their inter-operation and communication are established, and a test is then performed on the software.
  • Functional Testing: Output to input functionality of the software is used as the testing strategy to check every single function of the software.
  • Regression Testing: In this, developers check if the bug fixing happens only at those places where it is required. Regression testing is to repeatedly check if the bug fixing is at the core area and not impacting the other functionalities of the software.
  • System Testing: Once the software is combined collectively, it is checked once again to confirm if the software is equally working at every level.
  • Performance Testing: once the failures are removed, the software is tested for its performance and speed.
  • Acceptance Testing: This is the final level of software testing where the software product undergoes the examination of users to check whether they like the software or not.

What are software testing techniques?

Basically, in the software testing mechanism, there are 3 types of testing methodologies that are used by the developers and software testers. Each of the testing techniques is described below.

1. White Box Testing Technique – It examines the program code structure along with the business logic in the coding algorithms. This technique validates the code or program of an application. That is why it is also known as Clear Box, Open Box, and Glass Box Testing. This technique includes activities such as:

    • Examining all programming statements used in developing software.
    • Running all tests successfully to ensure that when each software node is tested, the software performs well.
    • Every software path is checked to watch over the proper functioning of the software.

2. Black Box Testing Technique – It tests the application’s functionality based on the specification of the requirements. This technique includes:

    • Boundary Value analysis
    • Domain Tests
    • Equivalence Partitioning
    • Decision Tables
    • Exploratory Testing

3. Grey Box Testing Technique – It is performed in the applications’ internal structure but with less information. It is performed at the critical areas of application models in a software development lifecycle. The model includes the checking of development methodologies such as:

    • Waterfall model
    • Agile model
    • V model
    • Spiral model
    • Rapid Application Development

The importance of testing in the software development process

The current trend of technology is constantly changing and making our lives more perfect with digitalization. As per the current trend, automation and digitization have improved the lives of every person.

A small bug can impact the size and revenue of any business anytime. Hence, it is always important to fix the bugs. Therefore, the demand for software testers in the USA is growing fast.


It is always important for any custom software development services company in the USA to choose proper software testing techniques, methodologies, strategies, and tools that fit best to the core functionalities of the software. You can consider software testing as a versatile activity that should be completed in each timeline to get a more flexible and efficient IT software product.
