Difference between E2E and System Testing
-
System Test uses own data and E2E Test uses Production data

System Test uses Production data and E2E Test uses own data

Both uses Production data

Both uses own data
System Testing uses its own test data specifically created for testing purposes, while End-to-End (E2E) Testing uses production-like data to simulate real-world scenarios. E2E testing validates the entire system flow with realistic data volumes and patterns, whereas System testing focuses on individual components with controlled test data.
System Testing is typically run in an isolated test environment using its own synthetically created test data, so testers can control and reset conditions freely. End-to-End (E2E) Testing, by contrast, validates the complete real-world flow and is often run against production or production-like data to catch issues that only surface with real data volumes and variety.
