- 14. Unit Test The main aim is to isolate each part of a program and show that the section of code works correctly.
- 15. Integration Test Involves testing of combined parts of a program to ensure its working based on user requirement.
- 16. System Test Is performed when all components of a program are integrated and tested to ensure functionality.
- 17. Writing Test in JS5
- 18. JavaScript does not natively supports testing It employs the good will of some of its frameworks and library to achieve this fit for testing in both Node and browsers
- 19. Some JS Testing Frameworks ◉Mocha ◉Jasmine ◉Jest ◉Selenium ◉QUnit ◉Tape ◉Protractor
- 20. Some JS Testing Library ◉Chai ◉Sinon ◉Enzyme ◉Unexpected ◉WebdriverIO ◉ and many others
- 22. Why Mocha? ◉ a feature-rich JS testing framework that runs on node and browser ◉ most used testing framework for testing ◉ support usage of 3rd party library for assertion, mocks, spy and others
- 23. Adding Mocha to Project //Mocha can be installed with npm, bower and available on cdnjs //install globally with npm using npm install -g mocha //install as a dev dependency for your project npm install --save-dev mocha //installed using bower as bower install mocha
