Scala Play test can't find WSClient during dependency injection
<p>I'm trying to DI a class into a Unit Test, using the following:</p>

<pre><code>val injector = new GuiceInjectorBuilder().injector()
val secured = injector.instanceOf[Secured]
</code></pre>

<p>However when I try and run it, I get the following error:</p>

<pre><code>[info] Exception encountered when attempting to run a suite with class name: org.scalatest.DeferredAbortedSuite *** ABORTED ***
[info]   com.google.inject.ConfigurationException: Guice configuration errors:
[info] 
[info] 1) No implementation for play.api.libs.ws.WSClient was bound.

[info]     for parameter 3 at com.fredley.Secured.&lt;init&gt;(Secured.scala:36)
[info]   while locating com.fredley.Secured

...
</code></pre>

<p>What am I doing wrong?</p>
