Interview Questions and Answers

Examples include: Selenium, JUnit, TestNG, Cypress, Appium, and Playwright. The best tool depends on the specific project requirements and technologies used.

Good communication involves regular meetings, clear documentation, using collaboration tools, providing timely feedback, and actively listening to team members and stakeholders.

Challenges include: tight deadlines, incomplete requirements, constantly changing requirements, complex systems, lack of resources, and communication barriers.

Staying updated involves: reading industry blogs and articles, attending conferences and webinars, participating in online communities, taking courses and certifications, and experimenting with new tools and techniques.

In Agile, QA is integrated throughout the development process, with testers working closely with developers and product owners in short sprints. Testing is continuous and collaborative, focusing on delivering working software increments.

Severity refers to the impact of the bug on the systems functionality. Priority refers to the urgency with which the bug needs to be fixed. A bug can have high severity but low priority, or vice versa.

Test Driven Development (TDD) is a software development process where tests are written before the code is written. The development cycle is: write a failing test, write the code to pass the test, and then refactor the code.

Common QA metrics include: Defect density (number of defects per lines of code), Defect removal efficiency (percentage of defects found before release), Test coverage (percentage of code covered by tests), Test execution rate (percentage of planned tests executed), and Customer satisfaction.

Regression Testing is re-running tests after code changes to ensure that existing functionality has not been negatively impacted. Its important to prevent the introduction of new defects (regressions) after modifications.

A bug report is a document that describes a defect found during testing. It should include: a clear and concise summary, steps to reproduce the bug, expected results, actual results, environment details (OS, browser, etc.), and severity/priority.

Common bug tracking tools include: Jira, Bugzilla, Mantis, Redmine, and Azure DevOps.

Bugs are typically prioritized based on their severity (impact on functionality) and priority (how quickly they need to be fixed). Severity can range from critical to cosmetic, while priority can range from urgent to low.

A test plan is a document that outlines the strategy and scope of testing for a software project. Key components include: test objectives, test scope, test environment, test strategy, test schedule, test deliverables, and risk assessment.

A test case is a set of conditions or variables under which a tester will determine whether a system, part of a system, or one of its features satisfies requirements. Key elements include: Test case ID, Test case name, Preconditions, Test steps, Expected results, Actual results, and Pass/Fail status.

Common techniques include: Black box testing (testing without knowledge of internal code), White box testing (testing with knowledge of internal code), Grey box testing (partial knowledge of internal code), Equivalence partitioning, Boundary value analysis, and Decision table testing.

Effective test cases should be clear, concise, specific, repeatable, and cover all relevant requirements. They should also include positive and negative test scenarios and focus on critical functionalities.

Key principles include: Prevention over detection (focus on preventing defects early on), continuous improvement (always seeking ways to improve processes), testing throughout the software development life cycle (SDLC), and focusing on customer satisfaction.

Common types of testing include: Unit testing, Integration testing, System testing, User Acceptance Testing (UAT), Regression testing, Performance testing, Security testing, and Functional testing.

Quality Assurance focuses on preventing defects by establishing processes and standards. Quality Control focuses on identifying defects in the product through testing and inspection. QA is proactive, while QC is reactive.

Quality Assurance (QA) is a systematic process of ensuring that a product or service meets specified requirements and standards. Its important because it helps prevent defects, reduces costs associated with fixing issues later, enhances customer satisfaction, and improves the overall reputation of the organization.

Quality assurance enables businesses to maintain high manufacturing and service standards. Quality control guarantees that the finished product meets these high expectations and meets the needs of the consumer.

Verification is the process of ensuring that software meets its objectives without errors. Validation is the process of determining whether a software product meets the required standards, or in other words, whether it meets the product's high level crite

When software or an application is given over to the testing team with the knowledge that a defect exists in the release, it is referred to as a bug release. Bug leakage occurs when a bug is identified by end users or customers but is not noticed by the t

The systematic assessment of an organization's quality management system is known as quality auditing. An internal or external quality auditor or audit team often conducts a quality audit.

Maturity Level 1 – Initial.

- Maturity Level 5 – Optimizing.

The Capability Maturity Model Integration (CMMI) is a process and behavioral model for software, product, and service development that helps organizations streamline process improvement and encourage productive, efficient behaviors that reduce risks.

The Capability Maturity Model Integration (CMMI) framework is used to integrate process improvement across several process areas. Systems engineering, software engineering, supplier sourcing and development, and integrated product and process development
