The Three Musketeers of Testing: Smoke, Sanity, and Regression
Ready, set, test! Introducing Smoke, Sanity, and Regression Testing
Understanding the differences between Smoke, Sanity, and Regression Testing is crucial for ensuring the quality and stability of software throughout its development lifecycle.
Each of these testing methodologies serves a unique purpose and is applied at different stages of the software development process to identify and fix issues efficiently. First things first, let's break it down with some definitions.
Smoke testing
Smoke testing is a preliminary level of testing that is performed on an initial build of the software to ensure that the most critical functionalities work correctly.
It is a subset of acceptance testing and is usually carried out by developers or testers. The term "smoke testing" comes from the hardware testing practice of turning on a new piece of hardware for the first time and considering it a success if it does not catch fire or smoke.
The objective of smoke testing is to verify the "stability" of the system in order to proceed with more rigorous testing.
It is not meant to be exhaustive but rather to quickly determine whether an application is suitable for further, more detailed testing. Smoke testing can be automated, and it is also known as a build verification test (BVT).
Sanity testing
Sanity testing, on the other hand, is a subset of regression testing and is performed on stable builds with minor changes in code or new functionality.
The main objective is to ensure that the recent changes function as intended and don't negatively impact the existing features of the application.
Unlike smoke testing, sanity testing is more focused and in-depth, concentrating on specific functionalities rather than the entire application.
It is typically performed by testers and can also be automated, focusing on major areas that may be affected by recent changes before proceeding to more comprehensive testing.
Regression testing
Regression testing is an approach to testing that ensures any existing functionality continues to work as expected after updates, configuration changes, or any code changes.
The primary goal is to identify any new defects or unintended impacts on the previously functioning parts of the application due to the alterations.
Regression testing, in contrast to Smoke and Sanity testing, is characterized by its thoroughness and attention to detail, involving the execution of all existing test cases and scenarios.
Testers or developers typically conduct this process, and it can also be automated. With adequate time and resources, the goal is to cover the full spectrum of existing test cases within a system, including both core functionalities and edge workflows.
Making these testing approaches work their magic
Getting the most out of these testing strategies is a must for keeping your software in top shape, especially when you're dealing with a tight schedule and limited resources.

Here's the game plan: nail the prioritization of test cases. Start by honing in on those critical, high-impact test scenarios that really cover the core of your application.
Keep a close eye on areas with recent code changes – they're prime spots for potential glitches. As you widen your testing net, weigh the risks in different parts of your software and divvy up resources wisely.
Stick to these pointers, and you'll optimize your testing efforts, hitting the most crucial aspects of your software while working around the constraints of time and resources.
A guide to handpicking your test cases
As systems get more complicated, the number of tests can skyrocket, making executions drag on for days or even weeks.
You gotta be strategic about picking and choosing tests, mainly because time and resources restrictions. With so many tests in the mix, it can get crazy, and running all of them might not be the smartest move.
So, the team's got this big task of figuring out which tests are critical, diving into some risk-based testing strategies, and keeping the test suite updated for maximum relevance.
Now, when it comes to Smoke, Sanity, and Regression testing, it's all about balance. You're juggling the depth of coverage you want with the need for an effective testing process.
Take a peek at the list below to find different ways to prioritize your test cases. The goal? Strike that perfect balance between covering all bases and speeding up the execution time:
Achieve better quality by letting Gravity pinpoint your test priorities
Think of Gravity as your testing team's sidekick – a unified platform crafted to amp up efficiency in Smoke, Sanity, and Regression testing. It's all about monitoring and blending insights from both real-life production and testing environments.
But here's where it really shines – creating "Quality Intelligence" and advanced analysis by running data through cool machine learning tricks like pattern recognition and trend analysis.
Gravity generates data-driven insights by monitoring how real users navigate live production and comparing it with the tests conducted in testing environments.
This helps testing teams pinpoint coverage gaps, spot features getting too much or too little attention, and cut out unnecessary testing in less crucial areas.
Conclusion
Embracing a data-driven strategy for selecting and prioritizing test cases not only enhances testing efficiency but also expands coverage, ultimately contributing to top-notch software quality.
