Comprehensive Guide to Mermaid Diagrams for QA Engineering— “Learn with AI” Edition

Quality Assurance workflows involve complex processes, multiple stakeholders, and intricate state transitions. Visualizing these workflows helps teams understand dependencies, identify bottlenecks, and communicate more effectively.

This guide presents practical diagram prompts across five categories, each addressing different aspects of QA engineering.

Process Flow Visualizations

Understanding the sequential flow of QA activities forms the foundation of effective test management. These flowchart prompts map out how work moves through various stages.

Create a Mermaid flowchart showing the complete QA lifecycle from requirement analysis through test planning, test design, test execution, defect reporting, regression testing, and finally release approval.

OUTPUT CHART

Create a Mermaid flowchart illustrating the bug triage process from initial report through assignment, fixing, testing, and closure.

Create a Mermaid flowchart depicting an automated testing workflow that includes test case creation, script automation, test execution, result logging, and report generation.

Create a Mermaid flowchart representing the manual testing process covering test design, test execution, defect logging, retesting, and closure.

Create a Mermaid flowchart showing regression testing after a release, including identifying regression cases, running automated tests, logging results, and approving the release.

OUTPUT SAMPLE

Create a Mermaid flowchart displaying the QA approval process from test execution through QA review, approval, and deployment.

Create a Mermaid flowchart tracking the defect lifecycle through states: new, assigned, in progress, resolved, verified, and closed.

Create a Mermaid flowchart demonstrating CI/CD QA integration from code commit through build, automated testing, test results, and the decision to deploy or fix.

Interaction Sequences

Understanding how different roles and systems interact reveals communication patterns and potential coordination issues.

Create a Mermaid sequence diagram showing QA test execution interactions between the QA engineer, test environment, test server, and result returns.

Create a Mermaid sequence diagram illustrating bug reporting and fixing workflow involving QA, bug tracker, developer, fix implementation, QA verification, and closure.

Create a Mermaid sequence diagram depicting a regression cycle from QA through automated test suite execution, test report generation, and QA lead review.

Create a Mermaid sequence diagram showing integration testing interactions between QA, system under test, CI/CD pipeline, test results, and QA feedback.

Create a Mermaid sequence diagram representing test case approval flow from QA engineer through QA lead, test plan approval, and execution authorization.

Create a Mermaid sequence diagram illustrating critical bug escalation from QA discovery through test manager notification, developer assignment, QA verification, and product owner notification.

Create a Mermaid sequence diagram showing the QA checklist sequence covering test design, test execution, result logging, retesting, and sign-off.

Timeline Planning

Scheduling QA activities requires understanding task dependencies and resource allocation across time.

Create a Mermaid Gantt chart for a one-week QA sprint including test planning, case writing, automated testing, manual testing, and reporting activities.

Create a Mermaid Gantt chart showing a release QA cycle with requirement review, test plan creation, automated test execution, manual testing, regression testing, and reporting.

Create a Mermaid Gantt chart tracking a bug-fix timeline from discovery through assignment, fixing, QA verification, and closure.

Create a Mermaid Gantt chart illustrating a regression testing schedule including case identification, test execution, defect logging, fix verification, and final approval.

Create a Mermaid Gantt chart providing a QA activities overview covering test design, environment setup, execution, defect logging, and retesting.

System Architecture

Understanding the structure of QA systems and their relationships helps in designing better testing frameworks.

Create a Mermaid class diagram modeling QA objects including TestCase, TestSuite, BugReport, and TestResult with relationships such as TestSuite containing TestCases.

Create a Mermaid class diagram representing QA team management structure with QAEngineer, Developer, TestManager, TestPlan, BugReport, and TestEnvironment entities.

Create a Mermaid class diagram designing a QA test management system with TestRun, TestCase, TestExecution, and BugTicket classes including their attributes and methods.

Create a Mermaid class diagram showing hierarchical relationships from TestPlan to TestSuite to TestCase to TestResult.

Create a Mermaid class diagram for defect tracking with BugReport entity including Reporter, Assignee, Severity, and Status attributes.

State Management

State diagrams help teams understand valid transitions and prevent invalid state changes in their workflows.

Create a Mermaid state diagram showing bug lifecycle states: new, open, in progress, resolved, verified, and closed.

Create a Mermaid state diagram tracking test case states: not started, in progress, blocked, passed, failed, and retest.

Create a Mermaid state diagram representing QA workflow stages from test planning through test design, test execution, review, and approval.

CHART CREATED BY PROMPT

Create a Mermaid state diagram illustrating regression test case states: pending, running, failed, retesting, passed, and archived.

Create a Mermaid state diagram showing CI/CD QA state flow from code committed through build started, automated tests, test passed or failed, and deploy or fix decisions.

Create a Mermaid state diagram depicting QA ticket escalation states: open, assigned, in review, critical, escalated, and closed.

Create a Mermaid state diagram tracking test environment states through setup, ready, testing, maintenance, and retired phases.

Create a Mermaid state diagram showing defect verification states: reported, assigned, fixed, retested, verified, and closed.

Advanced Integration Scenarios

Complex QA operations require combining multiple diagram types and perspectives.

Create a Mermaid flowchart showing combined automated and manual QA workflows for a complete software release.

Create a Mermaid sequence diagram illustrating QA regression testing integration with CI/CD pipelines.

OUTPUT SAMPLE

Create a Mermaid Gantt chart displaying a month-long QA sprint with overlapping automated and manual testing activities.

Create a Mermaid class diagram showing QA system objects with relationships to developers, test environments, and test plans.

Create a Mermaid state diagram modeling the combined lifecycle of QA test cases and defect tickets.

Create a Mermaid flowchart showing QA decision points including pass or fail evaluation, retest triggers, escalation paths, and approval gates.

Create a Mermaid flowchart for QA KPI tracking from number of bugs through severity levels, resolution time analysis, and QA metrics dashboard display.

Implementation Considerations

When implementing these diagram prompts, consider your team’s specific needs. Start with the most critical workflows causing confusion or bottlenecks. Use diagrams as living documentation that evolves with your processes. Share diagrams in team spaces where they remain visible and accessible.

Mermaid’s text-based format makes these diagrams easy to version control alongside your code and test documentation. Teams can review and update diagrams through standard pull request workflows, ensuring documentation stays synchronized with actual practices.
