Manual Testing Locally¶

Test Fix Applier Manually¶

// In Node.js REPL or test script
import { FixApplier } from './src/lib/github/fix-applier';

const result = await FixApplier.applyFixes({
  fileContent: 'const x = 5\nconst y = 10',
  fileName: 'test.js',
  language: 'javascript',
  vulnerabilities: [
    { line: 1, message: 'Missing semicolon', severity: 'low' },
    { line: 2, message: 'Missing semicolon', severity: 'low' }
  ]
});

console.log(result);
// Expected:
// {
//   success: true,
//   fixedContent: 'const x = 5;\nconst y = 10;',
//   appliedFixes: [
//     { line: 1, originalIssue: 'Missing semicolon', appliedFix: 'Added semicolon' },
//     { line: 2, originalIssue: 'Missing semicolon', appliedFix: 'Added semicolon' }
//   ]
// }

  fixes: [fileFixResult],
  branchName: 'main'
});

const prTitle = CommitBuilder.generatePRTitle(commits);
const prDescription = CommitBuilder.generatePRDescription(commits, 'main');

console.log(prTitle);
// Expected: "🔒 CodeSlick Auto-Fix: 1 file, 1 issue"

console.log(prDescription);
// Expected: Markdown-formatted PR description with file list

const job = await fixPRQueue.waitForJob(jobId, 10000);

console.log('Job status:', job.status);
console.log('Job result:', job.result);

2. GitHub API Testing (Real Repository)¶

Prerequisites¶

GitHub App (from Phase 4):
App ID
Private key (.pem file)
Installation on test repository
Test Repository:
Create dedicated test repo (e.g., codeslick-testing)
Install your GitHub App on this repo
Enable PR creation for the app

Setup Test Repository¶

# 1. Create test repo on GitHub
# https://github.com/new
# Name: codeslick-testing
# Visibility: Private
# Initialize with README

# 2. Install GitHub App on test repo
# Go to: https://github.com/apps/YOUR_APP_NAME
# Click: "Install App"
# Select: "Only select repositories" → codeslick-testing

# 3. Get installation ID
# Go to: https://github.com/settings/installations
# Click on your installation → URL shows installation ID

Test PR Creator with Real GitHub API¶

Create test script: scripts/test-pr-creator-real.ts

import { PRCreator } from '../src/lib/github/pr-creator';
import { CommitBuilder } from '../src/lib/github/commit-builder';

async function testRealPRCreation() {
  // IMPORTANT: Use your actual installation ID
  const INSTALLATION_ID = 12345678; // Replace with your installation ID
  const OWNER = 'YourGitHubUsername';
  const REPO = 'codeslick-testing';

  console.log('Testing PR creation with real GitHub API...');

  try {
    // Step 1: Create commits
    const commits = CommitBuilder.buildCommits({
      fixes: [
        {
          path: 'test.js',
          language: 'javascript',
          originalContent: 'const x = 5\n',
          fixedContent: 'const x = 5;\n',
          appliedFixes: [
            {
              line: 1,
              originalIssue: 'Missing semicolon',
              appliedFix: 'Added semicolon'
            }
          ]
        }
      ],
      branchName: 'main'
    });

    // Step 2: Generate PR metadata
    const prTitle = CommitBuilder.generatePRTitle(commits);
    const prDescription = CommitBuilder.generatePRDescription(commits, 'main');

    // Step 3: Create PR
    const creator = new PRCreator(INSTALLATION_ID);
    const result = await creator.createFixPR({
      owner: OWNER,
      repo: REPO,
      baseBranch: 'main',
      commits,
      prTitle,
      prDescription,
      originalPRNumber: undefined // No original PR for this test
    });

    console.log('✅ PR Created Successfully!');
    console.log('Branch:', result.branchName);
    console.log('PR URL:', result.prUrl);
    console.log('PR Number:', result.prNumber);

  } catch (error) {
    console.error('❌ PR Creation Failed:', error);
    throw error;
  }
}

// Run test
testRealPRCreation()
  .then(() => console.log('Test complete'))
  .catch((error) => console.error('Test failed:', error));

Run the test:

# Make script executable
npx tsx scripts/test-pr-creator-real.ts

# Expected output:
# Testing PR creation with real GitHub API...
# ✅ PR Created Successfully!
# Branch: codeslick/fix-main-1699876543210
# PR URL: https://github.com/YourUsername/codeslick-testing/pull/1
# PR Number: 1

Verification Steps:

Go to your test repository on GitHub
Check "Pull requests" tab
You should see a new PR titled "🔒 CodeSlick Auto-Fix: 1 file, 1 issue"
Verify:
✅ Branch created (codeslick/fix-main-{timestamp})
✅ Commit created with fix
✅ PR description shows file list
✅ File diff shows fix (added semicolon)

Test Complete Flow with Real GitHub¶

Create test script: scripts/test-complete-flow-real.ts

import { FixApplier } from '../src/lib/github/fix-applier';
import { CommitBuilder } from '../src/lib/github/commit-builder';
import { PRCreator } from '../src/lib/github/pr-creator';

async function testCompleteFlowReal() {
  const INSTALLATION_ID = 12345678; // Your installation ID
  const OWNER = 'YourGitHubUsername';
  const REPO = 'codeslick-testing';

  console.log('Testing complete flow with real GitHub API...');

  try {
    // Enqueue job (same as production)
    const jobId = await fixPRQueue.enqueue({
      teamId: 'test-team',
      installationId: INSTALLATION_ID,
      owner: OWNER,
      repo: REPO,
      originalPRNumber: 42,

            { line: 2, message: 'Missing semicolon', severity: 'low' }
          ]
        }
      ],
      maxRetries: 3
    });

    console.log('Job ID:', jobId);
    console.log('Waiting for job to complete...');

    // Wait for job (timeout: 60 seconds)
    const job = await fixPRQueue.waitForJob(jobId, 60000);

    if (job.status === 'completed') {
      console.log('✅ Job Completed Successfully!');
      console.log('PR URL:', job.result?.prUrl);
      console.log('PR Number:', job.result?.prNumber);
      console.log('Branch:', job.result?.branchName);
    } else {
      console.error('❌ Job Failed:', job.error);
      throw new Error(job.error);
    }

  } catch (error) {
    console.error('❌ Test Failed:', error);
    throw error;
  }
}

// Run test
testCompleteFlowReal()
  .then(() => console.log('Complete flow test passed'))
  .catch((error) => console.error('Complete flow test failed:', error));

Run the test:

npx tsx scripts/test-complete-flow-real.ts

# PR Number: 2
# Branch: codeslick/fix-main-1699876543210

3. Database Testing¶

Test Database Schema¶

1. Run Database Migration¶

# Generate migration from schema changes
npx drizzle-kit generate:pg

# Expected output:
# ✅ Generated migration: 0001_add_fix_prs_table.sql

# Apply migration to database
npx drizzle-kit push:pg

# Expected output:
# ✅ Applied migration successfully

2. Verify Table Creation¶

-- Connect to your Neon database
psql $DATABASE_URL

-- Check table exists
\dt fix_prs

-- Expected output:
--        List of relations
--  Schema |   Name   | Type  |  Owner
-- --------+----------+-------+----------
--  public | fix_prs  | table | postgres

-- Check table structure
\d fix_prs

-- Expected output: (44 columns)
-- id, team_id, installation_id, original_pr_number, ...
-- status, error_message, retries_count, created_at, ...

3. Test CRUD Operations¶

Create test script: scripts/test-database.ts

import { db } from '../src/lib/db';
import { fixPRs } from '../src/lib/db/schema';
import { eq } from 'drizzle-orm';

async function testDatabase() {
  console.log('Testing fixPRs table...');

  try {
    // 1. Insert test record
    const [inserted] = await db.insert(fixPRs).values({
      teamId: 'test-team-123',
      installationId: 'test-install-123',
      originalPrNumber: 42,
      originalPrUrl: 'https://github.com/test/repo/pull/42',
      originalBaseBranch: 'main',
      repoOwner: 'test-owner',
      repoName: 'test-repo',
      status: 'pending',
      jobId: 'test-job-123',
      maxRetries: 3
    }).returning();

    console.log('✅ Insert successful:', inserted.id);

    // 2. Query record
    const records = await db
      .select()
      .from(fixPRs)
      .where(eq(fixPRs.id, inserted.id));

    console.log('✅ Query successful:', records.length, 'record(s)');

    // 3. Update record
    await db
      .update(fixPRs)
      .set({
        status: 'completed',
        fixPrNumber: 43,
        fixPrUrl: 'https://github.com/test/repo/pull/43',
        completedAt: new Date()
      })
      .where(eq(fixPRs.id, inserted.id));

    console.log('✅ Update successful');

    // 4. Verify update
    const [updated] = await db
      .select()
      .from(fixPRs)
      .where(eq(fixPRs.id, inserted.id));

    console.log('✅ Verify successful:', updated.status, '===', 'completed');

    // 5. Delete test record
    await db.delete(fixPRs).where(eq(fixPRs.id, inserted.id));

    console.log('✅ Delete successful');

    console.log('✅ All database tests passed!');

  } catch (error) {
    console.error('❌ Database test failed:', error);
    throw error;
  }
}

// Run test
testDatabase()
  .then(() => console.log('Database test complete'))
  .catch((error) => console.error('Database test failed:', error));

Run the test:

npx tsx scripts/test-database.ts

# Expected output:
# Testing fixPRs table...
# ✅ Insert successful: a1b2c3d4-...
# ✅ Query successful: 1 record(s)
# ✅ Update successful

  console.log('\nBenchmark Results:');
  console.table(results);
}

7. Production Testing Checklist¶

Pre-Production Verification¶

Local Environment¶

All unit tests passing (95 tests)
All integration tests passing
Performance tests meet targets (<100ms small, <1s large)
Database schema applied successfully
Database indexes created
No console.log statements in production code
Environment variables configured

Test Repository¶

GitHub App installed on test repo
PR creation works with real GitHub API
Branch creation works correctly
Commit creation works correctly
PR metadata (title/description) correct
Multiple files handled correctly
Retry mechanism works (test with invalid credentials)

Database¶

fixPRs table created
All indexes created (3 indexes)
Relations work correctly (team, installation)
CRUD operations work
Query performance acceptable (<10ms with indexes)

Job Queue¶

Single job processing works
Multiple jobs processed sequentially
Retry mechanism works (3 attempts, exponential backoff)
Status tracking accurate (pending → processing → completed/failed)
Error messages captured correctly
Timestamps recorded correctly

Production Deployment¶

Week 2 Preparation¶

Before deploying to production (Week 2), ensure:

Replace in-memory queue with Inngest/Bull
Add webhook endpoint for PR events
Add API endpoints for job status
Add team dashboard UI
Add monitoring (Sentry, Datadog, etc.)
Add rate limiting for job creation
Add job cleanup (remove old completed jobs)
Add job prioritization (critical bugs first)
Add job cancellation support

Monitoring¶

Set up monitoring for:

Job queue length (alert if >100)
Job failure rate (alert if >10%)
Job processing time (alert if >30s)
GitHub API rate limit (alert if <1000 remaining)
Database connection pool (alert if >80%)
Error logs (alert on critical errors)

Rollback Plan¶

If production issues occur:

Disable feature flag: Turn off auto-fix PR creation
Stop job processing: Pause job queue
Investigate errors: Check logs, database, GitHub API
Fix and redeploy: Apply fix, test, redeploy
Re-enable feature: Turn on feature flag gradually

Load Testing (Week 2)¶

Test with realistic production load:

async function loadTest() {
  console.log('Running load test...');

  // Simulate 100 concurrent PR analyses
  const jobs = Array.from({ length: 100 }, (_, i) => {
    return fixPRQueue.enqueue({
      teamId: `team-${i % 10}`, // 10 different teams
      installationId: 12345,
      owner: 'testowner',
      repo: 'testrepo',
      originalPRNumber: i + 1,
      baseBranch: 'main',
      files: [
        {
          path: `file${i}.js`,
          content: 'const x = 5',
          language: 'javascript',
          vulnerabilities: [
            { line: 1, message: 'Missing semicolon', severity: 'low' }
          ]
        }
      ],
      maxRetries: 3
    });
  });

  const jobIds = await Promise.all(jobs);
  console.log('Enqueued', jobIds.length, 'jobs');

  const start = Date.now();

  // Wait for all jobs to complete
  await Promise.all(
    jobIds.map(id => fixPRQueue.waitForJob(id, 300000))
  );

  const duration = Date.now() - start;

  console.log('All jobs completed in', duration, 'ms');
  console.log('Average per job:', duration / jobIds.length, 'ms');
}
