14. What are the different types of test environments?

• Development environment: The environment in which the software is developed.
• Test environment: The environment in which the software is tested.
• Production environment: The environment in which the software is deployed.
• Staging environment: The environment in which the software is tested before it is deployed to production.

15. What is the role of a Systems Tester in Agile development?

• To work closely with the development team to define the testing strategy.
• To create and execute test cases.

Systems Testers play a vital role in ensuring the quality and reliability of software systems. They are responsible for designing and executing test cases to identify and document defects in the system. Their key job responsibilities include:

1. Test Planning and Design

Analyze the software requirements and specifications to identify potential areas for testing.

• Develop and execute test plans to ensure the thoroughness and effectiveness of testing.
• Design test cases that cover different aspects of the system’s functionality, performance, and usability.

2. Test Execution

Execute test cases manually or using automated tools to check for defects and system failures.

• Monitor system behavior during testing and record test results for analysis.
• Document and report defects to the development team for resolution.

3. Defect Analysis

Analyze defects identified during testing to determine their root causes and impact on the system.

• Classify defects based on severity and prioritize them for resolution.
• Work with developers to understand the cause of defects and provide recommendations for corrective actions.

4. Test Result Evaluation

Analyze test results to determine the effectiveness of testing and identify areas for improvement.

• Provide feedback to the development team on the system’s overall quality and reliability.
• Suggest improvements to testing processes and tools to enhance test efficiency and coverage.
