Testing Smart Contracts

Write integration tests for Algorand smart contracts using the algorandFixture and generated typed clients.

Default: Integration Tests (E2E)

Always write integration tests unless the user explicitly requests unit tests. Integration tests run against LocalNet and test real contract behavior.

Test Framework: Both Vitest (default) and Jest are supported. The examples below use Vitest syntax, but Jest equivalents work identically.

File naming

• Integration tests: contract.algo.e2e.spec.ts
• Unit tests (only if requested): contract.algo.spec.ts
