Migration Guide
Migration to Loadmill
This page provides a high-level overview of how teams migrate from existing test automation platforms to Loadmill. For the full step-by-step guide, see the detailed PDF below.
Overview
Migrating to Loadmill is not a traditional “rewrite your tests” process.
Instead of rebuilding existing test suites, Loadmill generates test coverage from real application behavior. This allows teams to move faster while improving reliability and reducing maintenance overhead.
What Changes
Manual test creation
Generate tests from real traffic
UI-heavy testing
API-first with targeted UI validation
High maintenance
AI-assisted, low maintenance
Test cases as assets
Business flows as assets
Regression as bottleneck
Continuous regression in CI/CD
Migration Principles
Avoid 1:1 migration of existing test cases
Focus on business-critical flows
Prefer real traffic over synthetic test design
Shift from UI-first to API-first thinking
Optimize for maintainability and scalability
How Migration Works (High-Level)
Identify key business flows Start with critical user journeys like onboarding, payments, or order flows.
Capture real traffic Use Loadmill to record real application behavior from browser, mobile, or network traffic.
Generate tests automatically Loadmill converts captured traffic into end-to-end test flows.
Add validations Enhance tests with API checks, business logic validation, and data assertions.
Integrate into CI/CD Run tests continuously as part of your pipelines.
Add targeted UI coverage Use UI automation only where it adds value.
Migration Strategy
Most teams follow a phased approach:
Phase 1: Run Loadmill alongside existing tools
Phase 2: Replace high-value flows
Phase 3: Expand coverage and optimize
Phase 4: Gradually decommission legacy tools
When Loadmill Works Best
Loadmill is ideal for:
Web and mobile applications
API-driven or microservices architectures
Systems with observable HTTP/HTTPS traffic
CI/CD-enabled environments
Some legacy systems may require evaluation or hybrid approaches.
Expected Outcomes
Teams typically see:
Faster test creation
Lower maintenance effort
More stable tests
Better end-to-end coverage
Faster feedback in CI/CD
Next Step
Start with a small pilot:
1–2 critical flows
Capture real traffic
Run in CI/CD
This will give a clear comparison against your current approach.
