Understand what is Smoke Testing


Smoke testing and sanity testing are vital testing types with distinct roles in the software testing process. While both ensure stability and functionality, they differ in purpose and execution. Let's explore the differences and advantages.


Smoke Testing:

Performed early in the testing process, smoke testing quickly assesses if the deployed software build is stable enough for further testing. It focuses on broad but shallow testing of critical functionalities. Smoke testing aims to identify major issues, saving time and resources by avoiding testing on an unstable build.


Sanity Testing:

Also known as "build verification testing," sanity testing follows the smoke test to verify software stability. It targets specific areas or functionalities that underwent changes or fixes. Sanity testing ensures that recent modifications haven't introduced critical issues, preparing the build for comprehensive testing.


Key Differences and Advantages:

Smoke testing provides an initial stability check, while sanity testing validates recent changes. Smoke testing is broad yet shallow, identifying major issues early on. On the other hand, sanity testing ensures stability post-modifications, reducing the risk of unnoticed critical issues.


Smoke testing advantages include early issue identification, time-saving, and verification of basic functionalities. Sanity testing validates recent changes, mitigating risks and ensuring a stable build for subsequent testing phases.


In conclusion, incorporating both smoke testing and sanity testing enhances software quality. While smoke testing checks overall stability, sanity testing focuses on recent changes. Together, they bolster the reliability and effectiveness of software products.

Quantum Computing Trends

With the advancements in technology, we shifted from traditional computers to its digital version, which included zero’s and one’s and now, to the latest and fastest upgraded computers i.e. Quantum Computers. Built on the pioneering ideas of physicists Richard Feynman and David Deutsch in the 1980s, Quantum Computers leverage the unique properties of matter at nanoscale. Quantum computing uses quantum physics to solve the problems which today’s computers can never tackle. There are two characteristics of quantum computer which make them the computers of the future. First, quantum computing is built on qubits that can be overlays of zero and one i.e. half part of a zero and a half part of a one at the same time. Second, qubits become entangled and exist in groups. Because of its capability to solve problems, high speed and accuracy, quantum computing has immediate applications in fields like pharmaceutical, cryptography, machine learning and search.

TDD BDD and SDET REsume

 **TDD vs BDD** Test-Driven Development (TDD) and Behavior-Driven Development (BDD) are both agile methodologies but with distinct focuses and processes. TDD vs BDD a developer-centric practice, emphasizes writing tests before the actual code, guiding software development through small, testable chunks. It's particularly effective in ensuring that the codebase remains bug-free and maintainable. BDD, on the other hand, extends TDD by specifying software behaviors using a language understandable by all stakeholders, including non-technical ones. This approach fosters collaboration and a shared understanding of the project's goals, making it easier to align development with customer needs and expectations. While TDD is focused on the technical aspects and validation of software functionality, BDD is more about clear communication and the behavior of the application from the user's perspective. **SDET Resume** An SDET Resume should effectively showcase a blend of software dev...
