Why Integration Testing Matters

Integration testing goes beyond basic unit tests by:
  1. Testing how different components interact with each other
  2. Simulating realistic blockchain conditions
  3. Verifying that your application works as expected in a chain environment
  4. Catching bugs that might only appear in specific chain contexts
For testing Neutron applications, we recommend:
  • cw-multi-test: A framework for testing CosmWasm contracts
  • Rust’s testing framework: For unit testing individual functions
  • Neutron’s testing utilities: For simulating Neutron-specific features
  • Docker: For setting up isolated testing environments

​
Prerequisites

Before diving into the integration testing tutorials, you should:
  1. Be comfortable with Rust programming
  2. Understand the basics of CosmWasm contract development
  3. Have completed the Onboarding Tutorials
  4. Have a project ready to test
