+# Client Hooks Test Suite
+
+This directory contains tests for the `@gadgetinc/client-hooks` package. These tests are designed to be framework-agnostic and test the core logic of each hook without depending on specific framework implementations or concrete API clients.
+
+## Test Architecture
+
+### Mock Adapter (`mockAdapter.ts`)
+
+The tests use a **mock adapter** that implements the `RuntimeAdapter` interface. This adapter simulates the behavior of framework-specific adapters (like React or Preact) without actually depending on those frameworks.
+
+Key components:
+
+- **Framework bindings**: Mock implementations of `useState`, `useEffect`, `useMemo`, etc.
+- **URQL bindings**: Mock implementations of `useQuery` and `useMutation`
+- **Context**: Mock Gadget API context for providing the client and connection
+
+### Test Approach
+
+Each hook test file follows a similar pattern:
+
+1. **Setup**: Create a mock adapter, API client, and connection
+2. **Initialize hooks**: Call `createHooks(adapter)` to initialize the hook system
+3. **Test hook behavior**: Call the hook and verify it:
+   - Returns the expected state shape
+   - Calls the appropriate connection methods with correct parameters
+   - Uses adapter hooks correctly (useMemo, useCallback, etc.)
+   - Handles options and edge cases properly
+
+### What These Tests DO Cover
+
+- ✅ Hook initialization and state shape
+- ✅ Correct parameters passed to connection operations
+- ✅ Proper use of adapter framework hooks
+- ✅ Options handling (pause, suspense, select, etc.)
+- ✅ Namespace support
+- ✅ Edge cases (stubbed actions, null data, etc.)
+
+### What These Tests DON'T Cover
+
+- ❌ Actual network requests and responses
+- ❌ Framework-specific behavior (React rendering, Preact lifecycle, etc.)
+- ❌ Real URQL client behavior
+- ❌ Integration with concrete Gadget API clients
+
+These integration tests will live in the framework-specific packages:
+
+- `@gadgetinc/react` - Full integration tests with React, real URQL, and mocked network responses
+- `@gadgetinc/preact` - Full integration tests with Preact
+
+## Running Tests
+
+```bash
+# From the package root
+pnpm test
+
+# Watch mode
+pnpm test --watch
+
+# With coverage
+pnpm test --coverage
+```
