Test Design

← Previous: Requirements & Design Analysis | Back to Testing Workflow | Next: Feature Testing →

Once the requirements and design analysis phase is completed and clarification questions have been addressed, QA proceeds with test design activities.

The goal of this phase is to prepare structured test cases and testing scenarios that will be used to validate the functionality implemented during the sprint.

Objectives

  • Create structured test cases covering planned functionality
  • Identify edge cases and risk areas
  • Prepare test data requirements
  • Define test case priorities
  • Organize test suites for efficient execution

During this phase QA performs the following activities:

Test Scenario Identification - identifying test scenarios based on the analyzed requirements and design - mapping test scenarios to functional requirements - covering positive, negative, and edge case scenarios - identifying boundary conditions and error handling

Test Case Creation - creating structured test cases to validate the expected system behavior - documenting test steps, expected results, and preconditions - ensuring test cases are clear, complete, and repeatable - including data requirements and test environment specifications

Edge Case and Risk Identification - identifying edge cases and potential risk areas - focusing on complex functionality and integration points - considering error scenarios and system boundaries - documenting assumptions and constraints

Test Data Preparation - preparing necessary test data where required - identifying test account needs and permissions - documenting data dependencies - planning test data creation and management

Test Case Prioritization - defining test case priorities based on business impact and risk - classifying test cases by severity and importance - identifying critical path test cases - planning test execution order

Automation Identification - identifying test cases suitable for future automation - flagging repetitive scenarios for automation consideration - documenting automation candidates - planning automation approach where applicable

Smoke Test Coverage - defining test cases to be included in smoke testing coverage - identifying critical functionality for smoke validation - documenting smoke test suite composition

Test Suite Organization - creating and organizing test suites for efficient test execution and future reuse - grouping related test cases by feature or functionality - structuring test suites for regression testing - preparing test execution plans

To accelerate the preparation of testing scenarios, AI-assisted tools may be used to generate initial drafts of test cases. These drafts are reviewed, refined, and validated by QA engineers before being used for testing.

Test Case Structure

Test cases typically include:

  • Test Case ID – unique identifier
  • Title – clear, descriptive name
  • Preconditions – system state and data requirements
  • Test Steps – detailed steps to execute
  • Expected Results – expected system behavior
  • Priority – importance level (Critical, High, Medium, Low)
  • Tags – categorization (smoke, regression, feature area)

Deliverables

Test Cases – Structured, prioritized test cases covering the functionality.

Test Suites – Organized collections of test cases for execution.

Outcome

The outcome of this phase typically includes:

  • a structured set of prioritized test cases covering the functionality planned for the sprint
  • defined test scenarios and validation coverage for the planned functionality
  • identified edge cases and potential risk areas
  • test cases prepared for execution during feature testing
  • identified test cases suitable for smoke testing and future automation
  • organized test suites to support efficient execution and reuse in future testing cycles

Quality Gates

  • All planned test cases are created, reviewed, and traceable to requirements
  • Edge cases and risk areas are identified and covered
  • Test data requirements are defined and data is available
  • Test case priorities and test suites are organized for execution
  • Test design documentation is complete and accessible
