70+ Manual Testing Interview Questions and Answers

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is named after Georg Simon Ohm, a German physicist.

• It is commonly used in electrical engineering and physics.

• The formula for Ohm's law is I = V/R, where I is the current, V is the voltage, and R is the resistance.

• Ohm's law can be used to calculate the current, voltage, or resistance in a circuit.

• It assumes that the temperature and ot...read more

Defects and bugs are flaws in software that affect functionality, performance, or user experience.

• Defects are deviations from expected behavior; for example, a login button not responding.

• Bugs can be syntax errors in code; for instance, a missing semicolon causing a crash.

• Defects can also be related to requirements; for example, a feature not meeting user specifications.

• Bugs may arise from integration issues; for example, two modules not communicating correctly.

• Defects can be...read more

Software testing life cycle is a process of testing software in a systematic and planned manner.

• The process includes planning, designing, executing, and reporting.

• It starts with requirement analysis and ends with the release of the software.

• It ensures that the software meets the quality standards and customer requirements.

• It helps in identifying defects and fixing them before the release.

• It includes different types of testing like unit testing, integration testing, system tes...read more

Test cases for AC

• Verify AC turns on when power button is pressed

• Check if AC cools the room to the desired temperature

• Test if AC shuts off automatically when the room is cool enough

• Ensure AC displays error message when filter needs cleaning

• Verify remote control works properly with AC

AC stands for alternating current and DC stands for direct current.

• AC changes direction periodically while DC flows in one direction.

• AC is used for power transmission while DC is used for electronic devices.

• AC voltage can be easily changed using a transformer while DC voltage cannot be changed easily.

• AC is more dangerous than DC as it can cause muscle contractions and fibrillation.

• Examples of AC sources are generators and power grids while batteries and solar cells are exampl...read more

Basics of testing involve verifying and validating software to ensure it meets requirements and functions correctly.

• Testing is the process of identifying defects or errors in software

• Verification involves checking if the software meets the specified requirements

• Validation involves checking if the software meets the user's needs

• Types of testing include functional, performance, security, and usability testing

• Testing can be done manually or through automated tools

SDLC models are frameworks used in software development to guide the process from initial planning to final deployment.

• Waterfall model: Sequential approach with distinct phases like requirements, design, implementation, testing, and maintenance.

• Agile model: Iterative approach with frequent feedback and collaboration between cross-functional teams.

• V-Model: Verification and validation model where each phase has a corresponding testing phase.

• Spiral model: Risk-driven model invol...read more

The bug cycle involves stages from identification to resolution, differing in focus and processes across various methodologies.

• Identification: Bugs are reported by testers or users. Example: A user reports a crash when opening the app.

• Classification: Bugs are categorized based on severity and priority. Example: A critical bug halting operations vs. a minor UI glitch.

• Assignment: Bugs are assigned to developers for fixing. Example: A developer receives a bug report for a login ...read more
