Functional Tester Interview Questions and Answers

Manual testing is done manually by humans while automation testing is done using tools and scripts.

• Manual testing is time-consuming and prone to human errors while automation testing is faster and more reliable.

• Manual testing is suitable for exploratory testing while automation testing is best for regression testing.

• Manual testing requires human skills and knowledge while automation testing requires programming skills.

• Manual testing is cost-effective for small projects while ...read more

HTTP methods in API include post, put, patch, and error codes for handling requests and responses.

• POST method is used to create a new resource on the server

• PUT method is used to update an existing resource on the server

• PATCH method is used to partially update an existing resource on the server

• Error codes such as 400 for Bad Request, 404 for Not Found, and 500 for Internal Server Error are used to indicate the status of the request

Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not.

• Testing is done to identify defects or errors in the system

• It involves executing a system or component with test cases

• The goal of testing is to ensure that the system meets the requirements and works as expected

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

TPM is a maintenance strategy that aims to maximize equipment effectiveness and minimize downtime.

• TPM involves regular maintenance and inspection of equipment

• It focuses on preventing breakdowns and reducing downtime

• TPM also involves training employees to perform basic maintenance tasks

• Examples of TPM activities include cleaning, lubrication, and inspection

• TPM can improve overall equipment effectiveness and reduce maintenance costs

Work life balance is the equilibrium between work responsibilities and personal life activities.

• Work life balance involves managing time and energy effectively between work and personal life.

• It is important for overall well-being, reducing stress, and preventing burnout.

• Examples include setting boundaries, prioritizing tasks, and taking breaks to recharge.

Bug Lifecycle is the process of a bug being identified, reported, fixed, retested, and closed.

• Bug is identified by a tester during testing

• Bug is reported to the development team

• Development team fixes the bug

• Tester retests the bug fix

• If bug is fixed, it is closed; if not, it goes back to development

Oops concepts in Python include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance allows a class to inherit attributes and methods from another class.

• Polymorphism allows methods to be written to handle different object types.

• Encapsulation restricts access to certain parts of an object and protects data.

• Abstraction hides complex implementation details and only shows the necessary features.

Power supply design involves creating a circuit that converts input power into a stable output voltage.

• Consider the input voltage range and required output voltage

• Choose the appropriate topology (e.g. buck, boost, flyback)

• Select components such as transformers, capacitors, and diodes

• Calculate component values and simulate the circuit

• Test and validate the design
