Test plans are created during which phase of the software development life cycle?a.Requirement Analysisb.Designc.Implementationd.Testing

Break Down the Problem

1. Identify the phases of the Software Development Life Cycle (SDLC).
2. Determine when test plans are typically created.

Relevant Concepts

The phases of the SDLC generally include:

• Requirement Analysis
• Design
• Implementation
• Testing

Test plans are essential for ensuring that the developed software meets specified requirements and is adequately tested.

Analysis and Detail

In the SDLC:

• Requirement Analysis focuses on gathering and analyzing requirements.
• Design involves creating the architecture and design specifications based on the requirements.
• Implementation is where the actual coding and development take place.
• Testing is the phase dedicated to validating the software against the requirements, but by this time, the test plans should already be prepared.

Test plans are typically developed during the Requirement Analysis and Design phases to set the groundwork for Testing.

Verify and Summarize

Based on the analysis, it is clear that test plans are created before the Testing phase, specifically during:

• Requirement Analysis: to ensure test cases are aligned with requirements.
• Design: to prepare for how those requirements will be validated.

Final Answer

Test plans are created during the Requirement Analysis phase and can continue to be developed during the Design phase. Therefore, the most appropriate answer is: a. Requirement Analysis.
