Extio Technology and Consulting LLP QA Analyst Interview Questions, Process, and Tips

Quality assurance focuses on processes to ensure quality, while testing involves executing tests to identify defects.

• Quality assurance is a proactive process that focuses on preventing defects by establishing processes and standards.

• Testing is a reactive process that involves executing tests to identify defects in the software.

• Quality assurance is process-oriented, while testing is product-oriented.

• Quality assurance in...read more

Different types of testing include functional testing, non-functional testing, manual testing, automated testing, regression testing, and performance testing.

• Functional testing: Testing the functionality of the software against the requirements.

• Non-functional testing: Testing aspects like performance, usability, and security.

• Manual testing: Testing performed manually by testers.

• Automated testing: Testing performed usin...read more

A test plan is a document that outlines the scope, approach, resources, and schedule of testing activities.

• Defines the objectives and scope of testing

• Outlines the test strategy and approach

• Identifies resources and schedule for testing

• Includes test cases, test scenarios, and test data

• Describes the roles and responsibilities of team members

Bug release refers to the process of making a software bug fix available to users.

• Bug release involves identifying and fixing a software bug

• Testing the fix to ensure it resolves the issue

• Deploying the fix to production for users to access

• Communicating the bug release to users and stakeholders

Load testing is a type of performance testing that simulates real-life user load on a software application to measure its performance under normal and peak conditions.

• Load testing helps identify the maximum operating capacity of an application.

• It helps in determining whether the current infrastructure is sufficient to handle the expected user load.

• Examples of load testing tools include JMeter, LoadRunner, and Apache Be

A test case is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly.

• Test cases are written based on requirements or user stories

• Each test case includes a set of inputs, expected outputs, and execution steps

• Test cases are used to validate the functionality of a system

• Test cases can be automated or executed manually

Bug leakage refers to bugs that are not identified during testing and are released to production.

• Bug leakage occurs when bugs are missed during testing and are found by users after the software is released.

• It can happen due to inadequate test coverage, lack of proper testing techniques, or miscommunication between teams.

• Examples include critical bugs in a mobile app that were not caught during testing and are discovere

QA should start as early as possible in the software development lifecycle.

• QA should start at the beginning of the project to ensure quality is built in from the start.

• QA should be involved in requirements gathering to prevent misunderstandings and defects.

• QA should start testing as soon as there is a deliverable, even if it's just a prototype.

• QA should collaborate with developers to identify and fix issues early on.

• QA...read more

Negative testing involves testing the system with invalid inputs or unexpected actions to ensure it handles errors properly.

• Testing the system with incorrect data

• Testing boundary conditions

• Testing error handling

• Ensuring the system fails gracefully

• Examples: entering letters in a number field, entering a future date for a past date field
