Chapter 5: Testing Instructions

Testing ensures your instructions work as intended. Anchor’s testing framework lets you simulate transactions and verify behavior.

• Key Points:

  • Run tests with anchor test.

  • Write tests in TypeScript/JavaScript.

  • Validate account states after execution.

• Code Example:

import * as anchor from "@coral-xyz/anchor";

describe("my_program", () => {
  it("Initializes the account", async () => {
    const program = anchor.workspace.MyProgram;
    await program.methods.initialize().rpc();
    // Add assertions here
  });
});

• Interactivity: Run the sample test and see pass/fail results in a simulated environment.
