Types of Testing 🧪

Type	Scope Level	Focus	Description	KPI
Unit Testing	Class/function level	Code logic	Tests individual units in isolation	Code Coverage > 70%
Integration Testing	Application level	IO, configuration	Tests interactions between application components	No misconfiguration / client initialization errors
Smoke Testing	App./System level	Major functions	Basic tests to verify critical functionality works	All critical paths working
Acceptance Testing	App./System level	Requirements	Confirms system meets business and user requirements	All user stories tested and accepted
Load Testing	App./System level	Real-world conditions	Tests up to peak expected load to capture scalability and validate performances	Response times within SLA at peak load
Stress Testing	App./System level	Max capacity	Tests under extreme loads to capture survivability, mitigation strategies and recovery	No crashes at defined extreme load levels

Different test types focus on different levels of scope, from isolated units up to overall system performance. Using a combination of testing types provides comprehensive test coverage.
