Smoke testing, also known as build verification testing, is a preliminary method used to ensure that critical functionalities of a software build are working correctly, enabling further testing. It focuses on verifying build stability and key functionalities, as well as validating the environment and configuration. Common tools for smoke testing include Selenium, Jenkins, and JUnit, which help automate tests and streamline the testing process.

1. Introduction to Smoke Testing: Its use and
tools
Introduction of Software Testing
The primary objective of testing is to ensure the quality and
reliability of a software application or system. By conducting
various tests, developers and quality assurance professionals can
verify that the software behaves as intended, meets the functional
and non-functional requirements, and performs well under
different conditions.
What is smoke Testing?
Smoke testing, also known as build verification testing (BVT) or
sanity testing, is an initial, high-level form of testing performed on

2. a software build or release candidate. Its purpose is to quickly and
superficially verify that the most critical functionalities of the
application are working correctly and that the build is stable
enough to proceed with further, more comprehensive testing.
The term "smoke testing" originated from hardware testing, where
it referred to turning on a device and checking for any signs of
smoke, which would indicate a major failure. In the context of
software testing, smoke testing involves executing a minimal set of
test cases, typically focusing on the core features or critical paths
of the application.
Why we use smoke testing?
1. Build Stability Check: Smoke testing ensures that the
software build or release candidate is stable enough for further
testing. It helps identify major issues or show-stopping defects
early in the testing process, allowing the development team to
address them before investing more time in comprehensive
testing.
2. Critical Functionality Verification: Smoke testing
validates the key functionalities of the software to ensure they are
working as expected. It helps ensure that the basic features and
core components of the application are functioning correctly
before proceeding with more detailed testing.
3. Environment and Configuration Validation: Smoke
testing also verifies that the software operates correctly in the
target environment and with the specified configurations. It helps
catch any issues related to compatibility, configuration settings, or
deployment procedures.
Tools which is used in smoke Testing?
There are several tools available that can assist in performing
smoke testing efficiently. These tools offer features to automate
the execution of smoke tests, generate reports, and help identify

3. any critical issues quickly. Here are some commonly used tools for
smoke testing:
Selenium: Selenium is a popular open-source tool used for
automating web browsers. It allows testers to create and execute
automated tests to validate the functionality of web applications.
Selenium WebDriver, in combination with a programming
language such as Java, Python, or C#, can be used effectively for
smoke testing web-based applications.
Jenkins: Jenkins is an open-source automation server that
provides a platform for continuous integration and continuous
delivery (CI/CD) processes. It enables the scheduling and
execution of smoke tests automatically whenever a new build or
release is deployed. Jenkins can integrate with various testing
frameworks and tools to facilitate smoke testing as part of the build
and deployment pipeline.
JUnit: JUnit is a widely used testing framework for Java
applications. It provides a framework for writing and executing
unit tests. JUnit can be utilized for smoke testing by creating test
cases that focus on critical functionalities or key application flows.
These test cases can be executed manually or integrated into an
automated testing framework.
