AMBITION JOB Senior Software Engineer Testing Interview Questions and Answers

Manual testing involves human testers executing test cases without automation to find defects based on requirements.

• Testers execute test cases manually to validate software functionality against requirements.

• Example: A tester manually checks if a login feature works by entering valid and invalid credentials.

• Manual testing is crucial for exploratory testing, where testers use their intuition to find defects.

• Example: A t...read more

Usability testing focuses on user experience, while security testing assesses vulnerabilities and data protection.

• Usability testing evaluates how easy and intuitive a product is for users. For example, testing a website's navigation.

• Security testing identifies vulnerabilities and ensures data protection. For instance, penetration testing to find security flaws.

• Usability testing involves real users performing tasks to g...read more

Integration testing is used to verify interactions between components in a system, ensuring they work together as intended.

• When multiple modules or services are developed separately and need to be tested together, such as a front-end and back-end integration.

• To validate data flow between different systems, like an API communicating with a database.

• When third-party services are integrated, ensuring that the application ...read more

Unit testing is used to validate individual components of software for correctness and reliability during development.

• Isolate functionality: Test a single function or method to ensure it behaves as expected. Example: Testing a 'calculateTotal' function.

• Catch bugs early: Identify issues in code before integration. Example: A unit test fails if a function returns an incorrect value.

• Facilitate refactoring: Ensure existing...read more

End-to-end testing verifies the complete functionality of an application from start to finish, ensuring all components work together.

• Tests the entire application flow, simulating real user scenarios.

• Includes testing of integrations with external systems, like payment gateways.

• Example: Testing an e-commerce site from product selection to checkout.

• Validates data integrity across different modules of the application.

• Ensur...read more

Age testing evaluates software behavior across different age-related scenarios and user demographics.

• Ensures software functions correctly for users of various age groups, e.g., children, adults, seniors.

• Tests age-related features, like parental controls or age verification processes.

• Validates UI/UX for different age demographics, ensuring accessibility for older users.

• Checks for age-specific content relevance, such as ...read more

A test plan is a detailed document outlining the strategy, scope, resources, and schedule for testing activities.

• Defines the objectives and scope of testing, e.g., functional, performance, security.

• Identifies the testing resources required, such as tools and personnel.

• Outlines the testing schedule and milestones, e.g., start and end dates.

• Specifies the deliverables, including test cases, test scripts, and reports.

• Inclu...read more

Various software tests ensure quality, functionality, and performance of applications across different stages of development.

• Unit Testing: Tests individual components for correctness (e.g., testing a function that calculates tax).

• Integration Testing: Ensures that different modules work together (e.g., testing API interactions between frontend and backend).

• Functional Testing: Validates the software against functional re...read more

The Software Development Life Cycle (SDLC) is a structured process for developing software applications through various stages.

• 1. Requirements Gathering: Identify and document what the software needs to do. Example: User interviews to gather feature requests.

• 2. Design: Create architecture and design specifications. Example: UML diagrams to visualize system components.

• 3. Implementation: Write and compile the code. Examp...read more

Functionality testing ensures that an application performs its intended functions correctly and meets specified requirements.

• User Interface Testing: Verify that all UI elements function as expected, e.g., buttons, forms, and navigation.

• Input Validation: Test how the application handles valid and invalid inputs, e.g., entering letters in a numeric field.

• Business Logic Testing: Ensure that the application processes data ...read more

HDLC is a bit-oriented synchronous data link layer protocol used for reliable communication over point-to-point and multipoint links.

• HDLC provides error detection and correction through frame check sequences (FCS).

• It supports both point-to-point and multipoint configurations.

• HDLC frames can be classified into three types: Information frames (I-frames), Supervisory frames (S-frames), and Unnumbered frames (U-frames).

• An ...read more
