LOAD IMPACT Mark Meier Client Success, Team Lead Load Impact Agenda ● Setting the Stage ● Q&A with Mark & Ragnar ● Audience Q&A Ragnar Lonn Load Impact Founder
LOAD IMPACT Setting the Stage Mobile App ● Standard REST API, running on AWS ● Python Backend ● App is live, positive user growth DevOps developer needs to load test ● Automated tests on staging system ● High level performance goals
LOAD IMPACT Q: Where should we start? Start with Requirements ● Per Endpoint Goals ● Which endpoints are important? ● How do they affect user satisfaction? Start Small
LOAD IMPACT Q: Test script considerations? Test Considerations ● Checks & Thresholds ● Sleep time ● Parameterization
LOAD IMPACT Q: How long should my tests run? API Testing Requests per Second 5+ minutes Website / Web App Testing Virtual Users (VUs) 2-5+ complete iterations of the user journey for ALL Virtual Users Ramping VUs
LOAD IMPACT Q: How do I interpret my test results? ● Exceeding defined Thresholds? ● Request rate should follow VUs ● Response time should stay stable
LOAD IMPACT Q: What are the different types of load tests? Baseline Tests-- Establish your Threshold Levels Load Tests Spike Tests Stress Tests Endurance Tests Threshold Threshold
LOAD IMPACT Q: What else can performance testing tell me? Performance Trends ● Has a code change introduced a performance regression? Infrastructure Issues ● Identify licensing, connection, memory, etc. configuration issues ● Optimize your app to reduce SaaS infrastructure costs Performance Trend Over Multiple Test Runs
LOAD IMPACT Q: How often should I run tests? Continuous Integration Pipeline ● Nightly builds - run small load tests ● Other considerations for DevOps and QA teams
LOAD IMPACT Q: How can I ensure scalability of my testing process? ● Use your Version Control System (VCS) ● Modularization ● Collaboration
