Verification and Validation in Testing

Introduction

You are at the right place! This is not a free vocabulary-building class but a critical evaluation of a much sought-after debate around verification and validation in the software testing world. Why do we need to know the difference between Verification and Validation? Even though they sound just about the same, they carry different meanings depending on what you intend to do as a tester/developer in the software development and testing process. They both go hand in hand while solving a problem. However, there is a lot of confusion around the meaning of these two words concerning software testing. While there may be many definitions of these terms in various fields on the internet, here we will look at these terms in the testing space and analyze both of these terms in detail.

Verification vs Validation

Software testing is a vast field. It involves various methods and processes proposed to solve different software testing issues. Verification and Validation are also a part of the same group in software testing. It is also known as a V-Model (Verification and Validation model) in the context of software development and testing.

BDD-Based Integration Testing Framework for Nebula Graph: Part 2

In BDD-Based Integration Testing Framework for Nebula Graph: Part 1, I introduced the evolution of integration testing for Nebula Graph. In this article, I will introduce how to add a test case into the test set and run all the test cases successfully.

Preparing Testing Environment

At the beginning of building the testing framework for Nebula Graph 2.0, we developed some tool classes to help the testing framework quickly start and stop a single-node Nebula Graph cluster, including checking for port conflicts and modifying part configurations. Here is the original execution procedure:

Integration Testing: What It Is and How to Do It Right

For software to work properly, all units should integrate together and behave correctly.

Integration testing is like inviting your two favorite groups of friends to the same birthday party and hoping they all get along. Will they cooperate and “blend” when they’re all in the same room? The only way to know is to perform an “integration test” by pulling them all together and seeing how they interact with one another.
