Ensure tests verify real operations and integration scenarios rather than just basic concepts or type definitions. Many test suites contain placeholder tests that only check if functions exist or verify simple type structures, but fail to test the actual behavior and interactions that matter in production.

Tests should cover:
Example of inadequate testing:
it("should understand queue concepts", () => {
type QueueItem = { id: string; callback: string; payload: unknown; };
const testQueueItem: QueueItem = { id: "queue-123", callback: "processData", payload: { data: "test" } };
expect(testQueueItem.id).toBeDefined(); // Only tests type structure
});
Example of proper functional testing:
it("should process queue items and handle retries", async () => {
const agent = await getAgentByName(env.TEST_AGENT, "queue-test");
// Test actual queue operations
await agent.enqueue("processData", { data: "test" });
const result = await agent.processQueue();
expect(result.processed).toBe(1);
expect(result.failed).toBe(0);
});
it("should sync state between multiple clients", async () => {
const client1 = new AgentClient({ agent: "TestAgent", name: "client1" });
const client2 = new AgentClient({ agent: "TestAgent", name: "client2" });
const client2Updates = [];
client2.onStateUpdate = (state) => client2Updates.push(state);
client1.setState({ count: 5 });
// Verify real multi-client synchronization
expect(client2Updates).toContainEqual({ count: 5 });
});
This approach ensures tests provide meaningful coverage of how systems actually behave in production rather than just verifying that code compiles or basic structures exist.
