As one might intuit, the jasmine-maven-plugin is a Maven plugin for the JavaScript testing framework, Jasmine.
If you're using Maven, you're probably writing Java (but, hey, you could be using it for any JVM-language). And if you're anything like me, you're here to figure out how to treat your client-side code with the same degree of professionalism that you already show server-side code. Maybe that means you want a painless way to test-drive your JavaScript. Maybe you're trying to figure out how to incorporate JavaScript tests on your continuous integration server without requiring any browser shenanigans.
