Karma Jawr Sample

The focus point is: Providing a way to show: how to write graceful javascript unittest in server render template engine.

Background

• Spring Framework
• Spring MVC
• JAWR
• JAWR Locale Message Generator
• Ext3

Features

• Karma + Mocha + Chai
• Sinon
• Integration with CI System

Problems

• How to load necessary JS files into runtime easily? Because Java side uses JAWR as assets bundling tool to compact multiple JS files into one. Then Front-end uses <script> tags to include those bundles. This make it difficult to get the correct dependencies JS files.
• How to mock the Locale Message Generator in global? Currently the JAWR Locale Message Generator is assigned as a property of the global object(We use it like locale.namesapce.field.a()). We need to construct this object when running test cases otherwise a lot of code will throw exception.
• No best practice for Ext3 can be found from Internet
