2. • “Unit tests” test individual units of code in isolation (for instance, individual
functions). They are fast and you usually have a lot of them.
• “Integration tests” test the integrations between different units, for
example the interaction between one module and its dependencies.
• “E2E (or end-to-end) tests” test the system as a whole, from the UI down
to the data store, and back.

4. TDD Benefits
• Application stability
• Easy refactoring
• Easy improvements
• Reusable code
• Safe production

5. TDD Drawbacks
• Development speed delay
• Bad test implementation
• May require additional resources

6. When writing tests ?
• Keep simple
• Single responsibility
• Separate by logic
• Make test fast
• Test more
