The reason is that now, not only one component is tested exclusively, but rather the whole system at once. Last but not least, there is a much higher test code maintenance cost, compared to unit tests. Thus, modifications which get persisted to databases or local storage will stay that way and may produce side effects for your next test run. Keep in mind that E2E tests, sometimes also referred to as integration tests, test your app's system as a whole. So, compared to unit tests, you will additionally need your web page up and accessible by the browser during test execution. When performing E2E tests you also need to take into consideration that you are actually testing a real web page. Needless to say, variations exist between the different browsers. So working with Promises becomes a major enabler when keeping track of deferred executions and responses.Īnother important aspect already noted is the necessity to translate programmatic actions into browser understandable ones. It doesn't matter whether you request a DOM Element, send some fake keystrokes or trigger a click, each of these actions needs to be automatically translated to understandable instructions and sent to the browser under test. One of the key differences when working with E2E tests is that all of your work is located in the browser, which naturally leads to writing a lot of asynchronous code. It's important to note that one method of testing does not replace the other, so don't take this article as an excuse to skip unit testing. This is different than unit tests, which take care of isolated parts of the application - called units - by verifying them through the removal or mocking of other parts. With E2E testing you are not interacting with the app's code per se, but with the app's interface. The key to success, of course, lies in the amount and quality of tests written. So by assembling a bunch of these - referred to as a test suite - you are able to verify that your web app acts as expected. Essentially, these stories describe a series of actions a user performs to achieve a certain goal. From a requirements-engineering-perspective you'd call those User Stories. What is E2E testing?Įnd-To-End (E2E) testing is all about testing your application against specific scenarios. This article will show you how to achieve this by combining Aurelia and Protractor. Not only do you want to ensure that your application's internal code operates correctly, but you also want to validate the in-browser behavior. To stay up to date with the latest features, patches, and security fixes make sure to always use the latest version of protractor-cucumber-framework as this module offers backward compatibility with other dependencies, like cucumber, or protractor.End to End Testing Testing front-end applications has become an important task for today's developers. is backward compatible with previous major versions of protractor-cucumber-framework.supports all the major versions of Cucumber.js,. Protractor-cucumber-framework is a thin wrapper and modules. Upgrading from previous versions and backward compatibility Odd-numbered Node.js releases (13, 15, 19, etc.) are not on the LTS line, should be considered experimental, and should Please note that to use protractor-cucumber-framework you'll need a recent Long-Term Support versions of Node.js, so 14, 16, or 18. Npm install -save-dev protractor-cucumber-framework
