10+ Associate Software Test Engineer Interview Questions and Answers

Java code to generate fibonacci series

• Use a loop to generate the series

• Start with the first two numbers 0 and 1

• Add the previous two numbers to get the next number

Bug life cycle is the process of identifying, reporting, fixing, retesting, and closing a software bug.

• Bug identification by testers

• Bug reporting with detailed information

• Bug fixing by developers

• Bug retesting to ensure it is resolved

• Bug closure after verification

Test cases for login functionality

• Verify valid username and password combination

• Verify invalid username and valid password

• Verify valid username and invalid password

• Verify empty username and password fields

• Verify special characters in username and password fields

Smoke testing checks basic functionality; sanity testing verifies specific functionalities after changes.

• Smoke testing is performed after a new build to ensure critical functionalities work. Example: Checking if the application launches.

• Sanity testing is done after bug fixes or enhancements to verify that specific issues are resolved. Example: Testing a fixed login feature.

• Smoke tests are broad and shallow, while sanity tests are narrow and deep.

• Smoke testing can be automated...read more

Agile model is a software development approach where requirements and solutions evolve through collaboration between self-organizing cross-functional teams.

• Iterative and incremental development

• Customer involvement and feedback throughout the development process

• Adaptive planning and flexibility to changes

• Regular team collaboration and communication

• Examples: Scrum, Kanban, XP

Waterfall model is a linear sequential software development process where progress flows in one direction like a waterfall.

• Sequential process with distinct phases: Requirements, Design, Implementation, Testing, Deployment

• Each phase must be completed before moving to the next

• No overlapping of phases

• Changes are difficult to implement once a phase is completed

• Example: Traditional software development approach

Smoke testing is a quick test to check if the software build is stable for further testing, while sanity testing is a subset of regression testing to ensure the specific changes made are working fine.

• Smoke testing is done to check if the critical functionalities of the software are working fine after a build, while sanity testing is done to check if the specific changes made in the software are working as expected.

• Smoke testing is a shallow and wide approach to testing, while...read more

Artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems.

• AI involves machines learning from data, recognizing patterns, and making decisions.

• Examples of AI include virtual assistants like Siri, self-driving cars, and recommendation systems like Netflix.

• AI can be categorized into narrow AI (focused on a narrow task) and general AI (possessing human-like intelligence).

Regression testing ensures that new code changes do not adversely affect existing functionalities.

• Regression testing is performed after code changes, like bug fixes or new features.

• It helps identify any unintended side effects caused by recent updates.

• For example, if a new feature is added to a web application, regression tests ensure existing features still work.

• Automated regression tests can save time and increase coverage, allowing for frequent testing.

• Regression testing c...read more

Software testing ensures quality, reliability, and performance of applications, preventing defects and enhancing user satisfaction.

• Identifies defects early: Catching bugs during development reduces costs and time. For example, finding a bug in a login feature before release.

• Enhances user experience: Testing ensures the software meets user expectations, like ensuring a mobile app is responsive and intuitive.

• Validates functionality: Ensures that all features work as intended, s...read more

Comparability testing evaluates if different products or versions meet the same standards and performance criteria.

• Used to assess if a new drug is comparable to an existing one in efficacy and safety.

• In software, it checks if updates maintain functionality across versions.

• Example: Comparing two versions of a web application for user experience consistency.

• In manufacturing, it ensures that different batches of a product meet quality standards.

SDLC focuses on the development of software, while STLC focuses on the testing of software.

• SDLC (Software Development Life Cycle) includes phases like planning, design, development, and deployment.

• STLC (Software Testing Life Cycle) includes phases like test planning, test design, test execution, and test closure.

• SDLC is focused on the overall development process, while STLC is focused on ensuring the quality of the software through testing.

• SDLC is more about building the soft...read more

Selenium is a popular automation testing tool used for web application testing.

• Selenium is an open-source tool used for automating web browsers.

• It supports multiple programming languages like Java, Python, C#, etc.

• Selenium WebDriver is the most commonly used component for writing test scripts.

• Selenium IDE is a record and playback tool for creating quick test scripts.

• Selenium Grid is used for parallel execution of test scripts on multiple machines.

• Selenium can interact with di...read more

AI stands for Artificial Intelligence, which is the simulation of human intelligence processes by machines. MI stands for Machine Learning, a subset of AI that allows machines to learn from data.

• AI involves creating intelligent machines that can mimic human behavior and perform tasks such as speech recognition, decision-making, and visual perception.

• Machine Learning is a subset of AI that focuses on developing algorithms that allow machines to learn from and make predictions ...read more
