This skill provides structured guidance for writing unit and integration tests for Anchor programs, enabling reliable verification of on-chain logic and client interactions.
Create a basic test suite for your Anchor program using Mocha and Chai, run it with anchor test, and verify account state changes.

To write unit tests for Anchor programs, use structured Mocha and Chai test suites to verify PDAs, CPIs, and error handling scenarios. Organize tests with describe blocks to isolate multi-program interactions and assert on-chain state changes.
A deterministic test environment for Solana Anchor development requires automated test workflows that ensure reproducible execution. Establish provider setup, configure account creation, and fetch program accounts to reliably verify client interactions and on-chain logic.
To assert on account state changes in an Anchor test, fetch the program accounts after execution and use Chai assertions. This verifies that the on-chain logic correctly modified the data within your deterministic test environment.
Yes, you can use Mocha and Chai to test error handling scenarios in Anchor programs. Structure your test suites with describe blocks to isolate and assert expected failures, ensuring robust verification of on-chain logic and client interactions.
Organize integration tests for Anchor multi-program interactions by using describe blocks to structure account creation and CPI scenarios. This approach maintains clear test organization and reliable verification of complex client interactions.
