## How to Use This Test Suite

### For Developers

1. **Run all tests**:
   ```bash
   bun test src/__tests__/components/graph/
   ```

2. **Run specific test file**:
   ```bash
   bun test src/__tests__/components/graph/DimensionFilters.test.tsx
   ```

3. **Generate coverage report**:
   ```bash
   bun test --coverage src/__tests__/components/graph/
   ```

4. **Watch mode**:
   ```bash
   bun test --watch src/__tests__/components/graph/
   ```

### For Code Reviewers

1. Check test coverage is 95%+
2. Verify edge cases are covered
3. Review error handling tests
4. Confirm accessibility tests

### For CI/CD Integration

1. Add to pipeline:
   ```yaml
   - name: Test Graph Components
     run: bun test src/__tests__/components/graph/
   ```

2. Enforce coverage threshold: 95%

3. Fail on test failures

## Key Testing Patterns

### 1. Component Rendering
```typescript
it("renders with expected content", () => {
  render(<Component {...props} />);
  expect(screen.getByText("expected")).toBeInTheDocument();
});
```

### 2. User Interactions
```typescript
it("calls callback on user action", async () => {
  const user = userEvent.setup();
  const onClick = vi.fn();
  render(<Component onClick={onClick} />);
  await user.click(screen.getByRole("button"));
  expect(onClick).toHaveBeenCalled();
});
```

### 3. Async Operations
```typescript
it("shows content after loading", async () => {
  render(<Component />);
  await waitFor(() => {
    expect(screen.getByText("loaded")).toBeInTheDocument();
  });
});
```

### 4. Utility Function Testing
```typescript
it("transforms data correctly", () => {
  const result = applyTransform(input);
  expect(result).toEqual(expected);
});
```
