Testcontainers vs Hoverfly
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- Tests run against the real database engine, so dialect and behaviour differences surface early.
- Containers are disposable, which removes shared-state flakiness entirely.
- Excellent language coverage with idiomatic APIs.
- Capture mode produces a realistic simulation from live traffic with no authoring.
- Latency injection makes it useful for performance and resilience testing too.
- Small footprint — a single Go binary.
Limitations
- Requires a Docker daemon in CI, which not every environment provides.
- Container startup adds seconds to each test run unless reused carefully.
- Heavier resource usage than in-memory alternatives.
- Smaller community and slower development than WireMock.
- Proxy configuration in complex networks takes effort.
- Captured simulations need periodic refresh.
Best for
Integration tests that currently use in-memory databases and lie to you.
Teams needing lightweight service virtualisation against real recorded traffic.
All of these integrate with: Docker, JUnit, Kubernetes.
