What is Smoke Testing?
Smoke Testing is a preliminary test to ensure that the major features of a software application work correctly. It is often referred to as "Build Verification Testing" (BVT) and is performed before detailed functional or regression testing begins.
🎯 Objectives
- Verify that the critical functions of the application are working
- Identify major issues early in the testing cycle
- Ensure that the build is stable for further testing
✅ Advantages
- Quick feedback on build quality
- Reduces risk of major defects going unnoticed
- Helps save time for detailed testing
⚠️ Limitations
- Does not cover detailed functionality
- May miss minor defects
- Only preliminary validation, not a full test
Smoke Testing Process
- Receive new software build from development team
- Identify critical functionalities to test
- Execute smoke test cases (manual or automated)
- Report major defects if found
- Decide whether the build is stable for further testing
Real-world Example
Example: After a new build of an e-commerce app, testers perform smoke testing to check if login, product search, and checkout functions are working before detailed functional testing.
Best Practices for Smoke Testing
Focus on critical functionality only
Use a small set of test cases (10-15 maximum)
Automate smoke tests for faster execution
Run smoke tests on every new build
