Testing a Go exchange API client: mocks, httptest and testcontainers
📰 Dev.to · Odilon HUGONNOT
Learn to test a Go exchange API client using mocks, httptest, and testcontainers for reliable and efficient testing
Action Steps
- Define an ExchangeClient interface to decouple the client from the implementation
- Use mockgen to generate mocks for the ExchangeClient interface
- Utilize httptest to test parsing of real API responses
- Employ testcontainers for PostgreSQL integration tests to ensure database interactions are correct
- Configure and run tests using the generated mocks and testcontainers
