Add tests (angular compliant)

[Brictarus]

Angular projects bootstrapped with angular-cli are initialized with basic jasmine tests. You really should add some tests examples in this example project to show people how to test their leaflet/angular application. It can be really tricky to check the map or tool states...

@Brictarus Thanks for the suggestion. This project was developed before I knew angular-cli. So the current folder may be different from the requirement of angular-cli and it is the reason why I did not introduce angular-cli. But I will move back to front-end development soon and definitely try angular 5 and angular-cli with Leaflet at that time (maybe in a new example project).

Front-end testing is certainly a need but it is challenging with map. I have been working in GIS/map development for a few years and have not seen a good solution or general guideline on it. If you have any suggestion, please let me know (particularly on what to test, given that I am a seasonal front-end dev and not very familiar with this area).

Update

Since angular-cli has been introduced into this project, we can use all standard tools and examples to write front-end tests now. Currently, tests in the code are automatically generated by angular-cli and not tuned for a map application. I will continue to see what I can do with them.
