# Task 6: Write Integration Tests

**Story**: Story 3 - Sprint Management Module
**Estimated**: 5 hours

## Description

Create comprehensive integration tests for Sprint management functionality including CRUD operations, status transitions, burndown calculation, multi-tenant isolation, and SignalR notifications.

## Acceptance Criteria

- [x] Integration tests for all 11 API endpoints (20 passing tests)
- [x] Tests for status transitions (Planned → Active → Completed)
- [x] Tests for business rule violations
- [x] Multi-tenant isolation tests (3 tests)
- [x] Burndown calculation tests (2 tests)
- [ ] SignalR notification tests (deferred to future sprint)
- [x] Test coverage >= 90% (comprehensive coverage achieved)
- [x] All tests passing (20/20 passing, 3 skipped awaiting Task infrastructure)

## Implementation Details

**Files to Create**:

1. **Integration Test Base**: `colaflow-api/tests/ColaFlow.Application.IntegrationTests/Sprints/SprintIntegrationTestBase.cs`
```csharp
public class SprintIntegrationTestBase : IntegrationTestBase
{
    protected async Task<Guid> CreateTestSprintAsync(
        Guid? projectId = null,
        string name = "Test Sprint",
        int durationDays = 14)
    {
        var command = new CreateSprintCommand
        {
            ProjectId = projectId ?? TestProjectId,
            Name = name,
            Goal = "Test Goal",
            StartDate = DateTime.UtcNow,
            EndDate = DateTime.UtcNow.AddDays(durationDays)
        };

        return await Mediator.Send(command);
    }

    protected async Task<Sprint> GetSprintAsync(Guid sprintId)
    {
        return await Context.Sprints
            .Include(s => s.Project)
