- Minimize `Thread.sleep()` - use only when absolutely necessary
- For timestamp tests: use minimal delays (50-100ms)
- Clean only test-specific indices (not `_all` unless needed)
- Use `runner.refresh()` after index operations
- Test with realistic multilingual content

### Key Test Classes

- `SuggesterRefactoringTest` - Index lifecycle, alias management
- `SuggesterTest` - Core functionality

## Run it { #run-it }

After that, you just need to install `pytest`.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

<div class="termy">

        // Verify they actually have the same weight
        long weightB = comparator.getProjectWeight(ProjectDependencyGraphStub.B);
