TypeScript for Web Testing, No Thanks - Check back in 10yrs
ProtractorJs is an end-to-end framework written for AngularJS applications. It uses Selenium WebDriver features internally. The main advantage of the regular WebDriver test is an ability to cooperate well with SPA application. The main problem with this type of systems is asynchronization. Single Page Applications change their look without reloading the whole page. So it is very hard to determine when the application is ready for action. Fortunately, Protractor knows the Angular internal mechanisms, so he is aware when application finish all operations.
The biggest problem with this framework is writing them in JavaScript. It is very powerful language, but not efficient enough for writing fast and without errors. Moreover, because it is not typed language and we don’t rely on IntelliSense in the editor, starting to work in the new library is hard. The best solution for this would be TypeScript. It is actively developed superset of JavaScript that gives us a power of static typing and hints in code. That’s why I decided to combine each other.
In this example, we will use a combination of TypeScript, Gulp and Jasmine to run Protractor tests.
