For what you're trying to do, :externs is not the solution.
Ultimately, all you need to do is make sure that both src-cljs/live and
src-cljs/test are on the classpath at compile time. The easiest way to do
this would be to put both builds into the same project:
:builds
{:live {:source-path "src-cljs/live" :compiler {...}}
:test {:source-path "src-cljs/test" :compiler {...}}}
When :builds contains multiple entries, they are all added to the
classpath, and thus helper.webTemplateTest will be able to load
helper.webTemplate.
:externs is used for a totally different purpose (JavaScript interop). If
you want to learn more about that, I recommend reading this:
