Test Generation and Quality Assurance Prompts
Prompt playbooks for AI coding agents to generate unit tests, integration tests, test fixtures, mocks, and stubs from repository context. Useful for QA engineers and developers because AI-generated tests must cover edge cases, respect existing test patterns, and avoid introducing flaky or low-value assertions.
Unit Test Generation from Source Code Prompt Template
For developers and QA engineers integrating AI coding agents into test pipelines. Produces unit test suites from source code that follow existing test patterns, cover edge cases, and avoid flaky assertions. Includes eval checks for test validity, pattern adherence, and coverage completeness.
Integration Test Scaffold Prompt for API Endpoints
For backend engineers building API test suites. Generates integration test scaffolds from endpoint definitions, including request fixtures, response assertions, and database state setup. Requires validation against OpenAPI specs and existing test conventions.
Test Fixture Factory Prompt from Database Schema
For developers needing realistic test data. Produces factory functions or fixture generators from schema definitions that respect constraints, relationships, and edge cases. Includes eval criteria for referential integrity and boundary value coverage.
Mock Object Generation Prompt for External Dependencies
For engineers isolating code under test from external services. Generates mock implementations that match interface contracts, simulate failure modes, and capture invocation expectations. Requires verification that mocks don't drift from real API behavior.
Edge Case Discovery Prompt for Function Signatures
For QA engineers and developers analyzing code for untested paths. Produces a structured list of edge cases from function signatures, type constraints, and control flow analysis. Includes prioritization by risk and coverage gap severity.
Flaky Test Diagnosis and Repair Prompt
For reliability engineers and test infrastructure teams. Analyzes flaky test logs, code changes, and execution patterns to identify root causes and suggest repairs. Requires correlation of failure patterns with timing, ordering, and state dependencies.
Test Coverage Gap Analysis Prompt
For engineering leads assessing test quality beyond line coverage metrics. Produces a gap report identifying untested branches, missing integration scenarios, and under-tested error paths from repository analysis. Includes remediation prioritization.
Property-Based Test Generation Prompt
For developers adopting property-based testing frameworks. Generates invariant properties, input generators, and shrinking strategies from function specifications. Requires validation that properties are falsifiable and cover meaningful behavior.
Behavior-Driven Development Scenario Prompt
For teams using BDD frameworks like Cucumber or Behave. Converts acceptance criteria into Gherkin scenarios with step definitions that map to existing step libraries. Includes eval checks for scenario atomicity and reusability.
End-to-End Test Flow Generation Prompt
For QA engineers designing system-level test scenarios. Produces end-to-end test flows from user journey descriptions, including setup, assertions, and teardown steps. Requires validation of flow completeness and environment dependency documentation.
API Contract Test from OpenAPI Spec Prompt
For API platform teams validating implementation against contracts. Generates contract tests from OpenAPI specifications that verify status codes, response schemas, headers, and error formats. Includes eval for spec coverage and breaking change detection.
Database Migration Rollback Test Prompt
For backend engineers and DBAs validating migration safety. Produces test cases that verify forward migration, rollback integrity, and data preservation. Requires checks for irreversible operations and constraint violations during rollback.
Retry and Timeout Behavior Test Prompt
For SREs and backend engineers testing resilience patterns. Generates test scenarios for retry logic, timeout configurations, and backoff strategies from code analysis. Includes eval for idempotency violations and cascading failure risks.
Security Fuzzing Input Generation Prompt
For security engineers and DevSecOps teams. Produces fuzzing inputs targeting input validation boundaries, injection vectors, and parser edge cases from code analysis. Requires categorization by vulnerability class and exploitability assessment.
Authentication and Authorization Test Prompt
For security engineers validating access control implementations. Generates test matrices covering role-based access, token validation, session management, and privilege escalation attempts. Includes eval for complete permission coverage.
Schema Evolution Compatibility Test Prompt
For API platform teams and data engineers managing schema changes. Produces backward and forward compatibility tests from schema diffs, including consumer impact assessment. Requires validation against semantic versioning and deprecation policies.
Rate Limiting Behavior Test Prompt
For API platform engineers testing throttling implementations. Generates test scenarios for rate limit enforcement, header accuracy, burst handling, and graceful degradation. Includes eval for fairness across client types and retry-after compliance.
N+1 Query Detection Test Prompt
For backend engineers and performance testers. Produces test cases that detect N+1 query patterns from ORM usage, GraphQL resolvers, and data loading code. Requires correlation with database query logs and performance baselines.
Deadlock Reproduction Test Prompt
For backend engineers investigating concurrency issues. Generates test scenarios that reproduce deadlock conditions from transaction patterns, lock ordering analysis, and isolation level configurations. Includes eval for reproducibility and minimal reproduction steps.
Network Partition Resilience Test Prompt
For SREs and distributed systems engineers. Produces test scenarios for network partition behavior, including split-brain detection, quorum loss, and partition healing. Requires validation against consistency guarantees and recovery procedures.
Golden Test Dataset Generation Prompt
For QA engineers and ML engineers needing stable test baselines. Produces curated test datasets with known-answer pairs, edge cases, and regression anchors from production data patterns. Includes eval for dataset stability and coverage representativeness.
Test Execution Order Optimization Prompt
For test infrastructure teams reducing CI pipeline duration. Analyzes test dependencies, historical failure patterns, and execution times to suggest optimal ordering and parallelization. Requires validation that reordering doesn't introduce flakiness.
Test Report Summarization Prompt
For engineering leads and QA managers reviewing test results at scale. Produces structured summaries from test run outputs, highlighting failures, flaky tests, coverage changes, and trend anomalies. Includes eval for actionable signal extraction from noisy test output.
