title: How to use gradle-android-test-plugin
body: <p>I want to get Robolectric working with Android Studio and am attempting to use [gradle-android-test-plugin][1] after reviewing answers to this [question][2], but am having no luck.</p>
  
  <ol>
  <li>I created a brand new Android project and named it MyApp.</li>
  <li>I followed all the instructions in the "Usage" section of the README.</li>
  <li>I didn't yet have any code to test in my new project, so I copied the classes (including the `RobolectricGradleTestRunner`) from the</li>
  </ol>
  
  <pre><code>gradle-android-test-plugin/example/src/test/java/com/example
  </code></pre>
  
  <p>and the</p>
  
  <pre><code>gradle-android-test-plugin/example/src/main/java/com/example 
  </code></pre>
  
  <p>directories into corresponding file paths in my new MyApp project.</p>
  
  <p>I've never implemented unit testing for Android before and I don't know what to do next. I successfully ran <strong><code>./gradlew install</code></strong> in the root directory of the the plugin, but doing the same in the root directory of my new project accomplishes nothing. It throws this complaint:</p>
  
  <pre><code>Task 'install' is ambiguous in root project 'MyApp'. Candidates are: 'installDebug', 'installTest'.
  </code></pre>
  
  <p>I'm not at all familiar with Gradle, so short of reading a textbook on Gradle itself, I'm not sure how to resolve this issue. </p>
  
  <p>If I enter the MyApp directory containing <code>AndroidManifest.xml</code> and try the <strong><code>../gradlew clean check</code></strong> to build and run the tests, I get this error:</p>
  
  <pre><code>Could not determine the dependencies of task ':MyApp:testDebug'.
  </code></pre>
  
  <p>Android Studio doesn't seem to be having any issues finding my dependencies. Can someone point me in the direction of running my tests, please? I imagine it's a simple terminal command or something that wasn't mentioned in the plugin's README. Cheers!</p>
  
  <p>edit:</p>
  
  <p>Here is my <code>build.gradle</code>. I'm aware it's not structurally identical to that of the example project included with the plugin, but that structure gave me identical errors.</p>
  
  <pre><code>buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.5.+'
          classpath 'com.squareup.gradle:gradle-android-test-plugin:0.9.+'
      }
  }
  
  apply plugin: 'android'
  apply plugin: 'android-test'
  
  repositories {
      mavenCentral()
  }
  
  android {
      compileSdkVersion 18
      buildToolsVersion "18.0.1"
  
      defaultConfig {
          minSdkVersion 11
          targetSdkVersion 18
      }
  }
  
  dependencies {
      compile 'com.android.support:support-v4:18.0.0'
  
      testCompile 'junit:junit:4.11'
      testCompile 'org.robolectric:robolectric:2.1.+'
      testCompile 'com.squareup:fest-android:1.0.+'
  }
  </code></pre>
  
  <p>edit2:
  Besides the fact that I was issuing the wrong commands (as indicated in Ravindra's answer), I also failed to realize my version of Gradle was too new (as Jake's comment points out).</p>
