End to End Testing with nightwatchjs
- 1. NIGHTWATCH FOR TESTING NODEJS APPLICATIONS S R I K A N T H M A D D U R I
- 2. WHAT ARE WE DOING TODAY?? • Compare most popular JavaScript Automation Frameworks • Get to know about them • Talk more about NightwatchJS • Why NightwatchJS • NightwatchJS Demo • Q & A
- 3. WHY NODEJS: • Increase of usage of client side technologies • Responsive and Light Weight dev. Technologies Ex: Javascript, AngularJs, ionic and react WHY JAVASCRIPT AUTOMATION FRAMEWORKS: • NodeJs Usage • Automation is in application code – SDET roles • Automation along with developer’s code • Run BDD locally • Tools evolved: Webdriver IO, Nightwatch, protractor with CucumberJS.
- 5. MOST POPULAR JAVA SCRIPT BDD TEST FRAMEWORKS: •Protractor •Webdriverio •NightwatchJs
- 6. • Protractor: wrapper of WebDriverJs • Supports NodeJs • AngularJs element identification • Error reporting. • Inbuilt Test runner • Parallel Testing • Mobile- No support. PROTRACTOR
- 7. WEBDRIVERIO • NodeJs supported • WebDriverIO: W3C webdriver API • Supports CucumberJS • Inbuilt Runner • wdio.conf.js file • Cloud extension • Mobile- support to automate mobile web Apps. • Community
- 8. WHY NIGHTWATCH • Supports Node.js • End-to-End (E2E) testing solution. • Built-in test runner. • Parallel Testing • Cross Browser Testing • Mobile Web App Testing Support • Continuous integration tool • Inbuilt screenshots • Inbuilt Assertion Library
- 9. CONT.... • Page Object Pattern • aliases for locators (@username) • Cloud extension • We Can use WebdriverIO apis • Easy to extend • Community
- 10. • Nightwatch: has it’s own implementation of the selenium WebDriver. And provides it’s own testing framework with a test server, assertions, and tools. • Framework- Can be used with other frameworks too, but can be especially useful in case you want to run functional tests not as part of other framework. • Syntax- looks the easiest and the most readable. WHAT NIGHTWATCH
- 12. CONS OF NIGHTWATCH • Return value methods should only use call backs • Call backs should given for every steps
- 13. CONCLUSION: • HERO of the Javascript Frameworks because: • For an E2E Testing, the webdrive.io, is still evolving, Nightwatch will be a great and also is easy to use the framework • Also it has very good inbuilt Debugging mechanism. Hence, Nightwatch is good for the E2E Testing. • NightWatchJS is itself is test runner, framework and having its own assertion library.
