This document discusses different types of software testing including unit testing, integration testing, end-to-end testing, and behavior driven development. It provides examples of JavaScript testing tools for each type including Mocha, Jest, Karma, Selenium and Cucumber. Testing approaches like test-driven development, behavior-driven development, and acceptance test-driven development are also covered. Links are provided to external resources and a GitHub repository demonstrating integration testing.

9. Red Green Refactor Cycle
TDD
Make a test case fail
Make the code work
Make the code clean

11. BDD
Scenarios
Behaviour
Scenario: Some determinable business situation
Given some precondition
And some other precondition
When some action by the actor
And some other action
And yet another action
Then some testable outcome is achieved
And something else we can check happens too

15. TDD -> BDD
Where to start
What to test and what not to test
How much to test in one go
What to call their tests
How to understand why a test fails

16. Unit Test
white box testing
mocked input -> f(x) -> expected output
for a chunk of codes
from programmer perspective
code coverage reporting

17. Integration Test
from user’s perspective
ensure the system is functioning as expected
Integration Test is functional test, but not vice
versa

18. Functional Test
black box test
includes E2E test, Acceptance test, browser
automations
browser/browser-like env
cross browser compatibilities
