What to test in AI-assisted software delivery

AI-assisted development can produce code quickly. That does not reduce the need for testing. It increases the need for testing discipline.

When more code, tests, configuration, and documentation can be generated faster, teams need a clear way to decide what is trusted, what is reviewed, and what must be verified before delivery.

Start With The Test Pyramid

Unit tests

Use unit tests to verify small pieces of logic: calculations, validators, mappers, business rules, permission checks, utility functions. AI can help generate unit tests, but generated tests still need review. A test that simply repeats the implementation's assumptions is not enough.

Integration tests

Integration tests verify how components work together: service to database, backend to queue, API to external provider, data pipeline step to downstream storage, internal module boundaries. These tests are important in AI-assisted work because generated code may look correct in isolation but fail at boundaries.

API tests

API tests verify request/response behavior, authentication, validation, error handling, and compatibility with clients. For systems with OpenAPI or other contracts, API tests can be tied to the documented interface.

Contract tests

Contract tests are useful when multiple services, clients, or vendors depend on stable behavior. They answer: Can the consumer and provider still work together? This matters when AI helps change code quickly. Fast changes can break integrations unless contracts are explicit.

End-to-end tests

E2E tests verify user-critical flows: sign up, submit an order, upload a document, process a call, generate a report, complete an admin workflow. E2E tests should focus on important journeys, not every possible UI detail.

Add User-Flow Scenario Testing

AI-assisted systems should be tested against real workflow scenarios. For example: user uploads an audio call → transcription completes → LLM analysis runs → CRM record updates → report becomes visible. This kind of scenario checks whether the system supports the actual business job.

Test Performance Where It Matters

Performance testing is not always needed at the same level for every MVP. But it becomes important when the system has:

• real-time workflows;
• speech/audio processing;
• high-volume API usage;
• dashboards over large datasets;
• background jobs;
• user-facing latency requirements;
• external provider dependencies.

Performance tests should focus on known risk points.

Test AI And LLM-Specific Risks

If the product uses LLMs or agents, include checks for:

• prompt injection;
• sensitive information disclosure;
• unsafe tool calls;
• excessive agency;
• output validation;
• hallucinated claims;
• data boundary violations;
• human review requirements.

OWASP's GenAI Security Project is a useful source for LLM application risk categories.

Add Static Analysis And Dependency Checks

Generated code should pass the same or stronger checks as human-written code: linting, type checks, static analysis, dependency vulnerability scanning, secrets scanning, license checks where relevant. Tools and services may vary by stack, but the principle is stable: AI-generated code should not bypass the quality gate.

What ITNeuroNet Provides

Depending on scope, delivery may include: test strategy; unit and integration tests; API and contract testing; E2E scenarios; performance/load testing where appropriate; static analysis; code review; security review; handoff notes; known-risk list.

The goal is not to promise that no bugs exist. The goal is to make delivery more reviewable, safer to change, and easier to hand over.
