Software Testing: Functional Vs Non-Functional Explained

 Software testing is a way to verify that the software product meets expectations and to make sure that it complies with all applicable laws. This involves the execution of software/system components using manual or automatic tools to evaluate one or several properties of interest. Software testing is used to find errors, gaps, or missing requirements that are not present in the actual requirements.

Software Testing: Why is it Important?


Bugs and errors can be detected early with software testing so that they can be fixed before the product is shipped, A properly tested software product will ensure reliability, security, and high performance. This results in cost savings, customer satisfaction, and time efficiency.





What are the advantages of Software Testing?


Here are some of the benefits of software testing


  • It's cost-effective: Software testing has many benefits. It is possible to save money by testing any IT project in a timely manner. It is cheaper to fix bugs that were discovered earlier in software testing.
  • Security: Software testing is the most sensitive and vulnerable benefit. Trusted products are sought after by people. This helps to eliminate risks and problems sooner.
  • High-quality product: Software products must have tested. Customers receive a high-quality product only when testing is done.
  • Customer satisfaction: Any product's main goal is to satisfy its customers. UX/UI Testing is essential to ensure the best user experience.



Functional vs. non-functional testing


Your goal is to use multiple testing methods in your software development process. They can be divided into functional and non-functional testing. Functional testing is testing the application against business requirements. Functional testing includes all types of tests that are used to ensure each component of a piece or software works as intended. It is usually done using use cases provided by business analysts and the design team. These tests are typically performed in an ordered fashion and include:


  • Unit testing
  • Integration testing
  • System
  • Acceptance

Non-functional testing methods include all types of tests that focus on the operational aspects. These include:

  • Performance
  • Security testing
  • Usability
  • Tests for compatibility

A robust testing framework is essential to release high-quality software that can easily be adopted by your users.

Explore the Basic Types of Software Testing

Software testing is a vital procedure in the IT industry. The method involves testing the features and validating the operation of the program effectively. This is a very important branch of this IT field since any applications created are tested to make sure its effectiveness and proficiency based on its specifications and testing strategies. It also helps to detect any type of defects and flaws in the functioning of the applications which in turn helps the programmer to take the mandatory measure and create software with flawless operation. There are different types of software testing done based on purposes. Every type is this classification relies upon its function and importance in the testing process. There is functional testing that is done in order to test any kind of functional defects in the software and ensure proper operation. Then there is performance testing that is principally done when the software is not functioning correctly.  Under such a situation tes...

What is DevOps and Why is It So Widely Used?

So what exactly is DevOps? Let's take a small hypothetical example to illustrate. Let us say there's a small startup that assembles AI-enabled cleaning robots. There are 3 programmers (let's be lazy and simply call them Team D) who compose and execute the code to produce the robots and 2 operational people (Team O of course) who maintain the robot infrastructure in the real-world environment and supply aid for the robot consumers. Team D has only spent 8 months producing the latest robot. It can recognize individuals, take orders from Alexa devices, and clean like a boss. Team D has spent time producing this robot into their controlled dev environment and everything seems to be working smoothly. They couldn't be prouder. They hand over their production to Team O that immediately takes it out to the real world. That's when the problems start. It turns out that the perfect cleaning robot isn't so perfect after all. It does not recognize everybody, it can follow Al...

What's Integration Testing?

The integration testing definition refers to analysing the communication between separate software modules. Normally, the project team has to unit test the machine before moving on to integration testing. From the software development life cycle, integration testing is the next step. The main aim of integration testing is to make sure the differences in logic patterns developers use when creating a module do not undermine the connectivity of the system. There are several methods to integration testing: In case one of those modules isn't ready for testing yet, QA teams use stubs. Bottom-up integration testing is the contrary method to top-down integration testing. It implies validating basic modules first and integrating the complex ones later. The rationale behind the strategy is that it requires less time to make a low-level module -- that is why such components should be tested even if the more complex areas of the system are still in evolution. Big bang. If the t...
