Running Tests

Prerequisites

1. Database Setup: Tests require a running PostgreSQL database

   # Option 1: Use local database
   export DATABASE_PASSWORD=postgres
   
   # Option 2: Use DATABASE_URL for containerized testing
   export DATABASE_URL="postgresql://user:pass@localhost:5432/bookhoard"
   

2. Dependencies: Ensure all Go dependencies are installed

   go mod download
   

Running All Tests

# Run all tests in the test suite
cd cmd/server/tests
go test -v

# Run with coverage report
go test -v -coverprofile=coverage.out
go tool cover -html=coverage.out

Running Specific Test Files

# Run only authentication tests
go test -v -run TestAuth

# Run only analytics tests
go test -v -run TestAnalytics

# Run specific test function
go test -v -run TestAnalyticsReadingStats

Running Tests in Container

# Build and run tests in Docker container
podman-compose up -d db
podman build -t bookhoard-test .
podman run --network bookhoard_default -e DATABASE_URL="postgresql://postgres:postgres@db:5432/bookhoard" bookhoard-test go test ./cmd/server/tests/ -v

Test Modes

# Short mode (skip lengthy tests)
go test -short -v

# Verbose mode with detailed output
go test -v

# Race detection

Adding New Tests

Template for Endpoint Tests

package main

import (
    "bytes"
    "encoding/json"
    "net/http"
    "testing"

    "github.com/stretchr/testify/assert"
    "github.com/stretchr/testify/require"
)

func TestNewEndpoint(t *testing.T) {
    t.Run("Endpoint_WithoutAuth", func(t *testing.T) {
        ts, _, _, _ := setupTestServer(t)
        defer ts.Close()

        // Test without authentication
        req, _ := http.NewRequest("GET", ts.URL+"/api/new-endpoint", nil)
        client := &http.Client{}
        resp, err := client.Do(req)
        require.NoError(t, err)
        defer resp.Body.Close()

        assert.Equal(t, http.StatusUnauthorized, resp.StatusCode)
    })

    t.Run("Endpoint_WithAuth", func(t *testing.T) {
        ts, db, _, _ := setupTestServer(t)
        defer ts.Close()

        token := loginTestUser(t, ts, db)

        // Test with authentication
        req, _ := http.NewRequest("GET", ts.URL+"/api/new-endpoint", nil)
        req.Header.Set("Authorization", "Bearer "+token)

        client := &http.Client{}
        resp, err := client.Do(req)
        require.NoError(t, err)
        defer resp.Body.Close()

        assert.Equal(t, http.StatusOK, resp.StatusCode)

        var result map[string]interface{}
        json.NewDecoder(resp.Body).Decode(&result)

        // Add assertions for response structure
        assert.Contains(t, result, "expected_field")
    })

    t.Run("Endpoint_InvalidInput", func(t *testing.T) {
        ts, db, _, _ := setupTestServer(t)
        defer ts.Close()

        token := loginTestUser(t, ts, db)

        // Test with invalid input
        req := map[string]interface{}{
            "invalid": "data",
        }
        body, _ := json.Marshal(req)

        httpReq, _ := http.NewRequest("POST", ts.URL+"/api/new-endpoint", bytes.NewBuffer(body))
        httpReq.Header.Set("Content-Type", "application/json")
        httpReq.Header.Set("Authorization", "Bearer "+token)

        client := &http.Client{}
        resp, err := client.Do(httpReq)
        require.NoError(t, err)
        defer resp.Body.Close()

        assert.Equal(t, http.StatusBadRequest, resp.StatusCode)
    })
}

Best Practices

1. Use Table-Driven Tests for multiple similar test cases
2. Test All Error Paths: Not just success cases
3. Validate Response Structure: Check all expected fields
4. Test Edge Cases: Empty inputs, invalid IDs, boundary values
5. Use Subtests: For organizing related test cases
6. Clean Up Resources: Always close response bodies
7. Use require.NoError for setup, assert.NoError for test conditions
8. Create Isolated Tests: Each test should be independent

CI/CD Integration

GitHub Actions Example

name: Integration Tests

on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest

    services:
      postgres:
        image: postgres:15
        env:
          POSTGRES_DB: bookhoard
          POSTGRES_USER: postgres
          POSTGRES_PASSWORD: postgres
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5

    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-go@v4
        with:
          go-version: '1.25'

      - name: Run integration tests
        env:
          DATABASE_URL: postgresql://postgres:postgres@localhost:5432/bookhoard
        run: |
          cd cmd/server/tests
          go test -v -race -coverprofile=coverage.out

      - name: Upload coverage
        uses: codecov/codecov-action@v3

Troubleshooting

Common Issues

1. Database Connection Errors

   # Ensure database is running
   podman ps | grep postgres
   
   # Check connection string
   echo $DATABASE_URL
   

2. Port Already in Use

   # Tests use random ports (port 0), so this shouldn't happen
   # If it does, check for running processes
   lsof -i :8765
   

3. Test Data Cleanup

   • Tests use automatic cleanup via defer ts.Close()
   • Manual cleanup may be needed for complex scenarios
   • Consider using database transactions for rollback

4. Time-Dependent Tests

   • Use fixed time values in tests
   • Mock time functions if necessary
   • Add tolerance for timestamp comparisons

Performance Considerations

Test Execution Time

• Total suite: ~2-3 minutes
• Individual test files: 5-30 seconds
• Use -short flag for faster CI runs
• Parallel test execution with -parallel flag

Optimization Tips

1. Use Test Caching: Go 1.18+ caches test results
2. Minimize Database Calls: Create test data once
3. Parallelize Independent Tests: Use t.Parallel()
4. Avoid Sleep: Use channels for synchronization

Future Improvements

Planned Enhancements

• Add property-based testing with github.com/stretchr/testify
• Implement fuzzing for input validation
• Add performance benchmarks
• Contract testing for API compatibility
• Visual regression testing for UI endpoints

Coverage Goals

• Current: ~95% backend coverage
• Target: 98% backend coverage
• Frontend: Add integration tests for frontend components
