Espresso UI testing doesn't recognize onView()

Question

I have spent all day setting up Junit4 instrumentation tests with Espresso, but just can't seem to get that final step. No matter what I do it won't recognize the onView() method. I have tried multiple SDK/support-lib versions and so far nothing. I have gone through all the google setup guides and many stackoverflow posts, turning here as my last hope.

Gradle version : com.android.tools.build:gradle:1.5.0

Gradle file:

apply plugin: 'com.android.application' apply plugin: 'com.google.gms.google-services'  android {     compileSdkVersion 23     buildToolsVersion "23.0.2"     useLibrary  'org.apache.http.legacy'      defaultConfig {         applicationId "lv.my.android"         minSdkVersion 9         targetSdkVersion 22         testApplicationId "lv.my.android.tests"         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"     }      packagingOptions {         exclude 'LICENSE.txt'         exclude 'META-INF/DEPENDENCIES'         exclude 'META-INF/LICENSE'         exclude 'META-INF/NOTICE'     }      compileOptions {         sourceCompatibility = 'VERSION_1_7'         targetCompatibility = 'VERSION_1_7'     }      signingConfigs {         beta {             storeFile file("beta.keystore")             storePassword "betabuild"             keyAlias "key"             keyPassword "betabuild"         }         release     }      buildTypes {         debug {             debuggable true             applicationIdSuffix '.debug'             versionNameSuffix '-DEV'             minifyEnabled false         }          beta {             debuggable true             applicationIdSuffix '.beta'             versionNameSuffix '-BETA'             signingConfig signingConfigs.beta             minifyEnabled false         }          release {             minifyEnabled false         }     } }  dependencies {     compile files('src/main/libs/guice-3.0-no_aop.jar')     compile files('src/main/libs/javax.inject-1.jar')     compile files('src/main/libs/roboguice-2.0.jar')     compile files('src/main/libs/junit-4.11.jar')     compile files('src/main/libs/hamcrest-core-1.3.jar')     compile files('src/main/libs/GeoLib.jar')     compile files('src/main/libs/GeoPolygons.jar')     compile files('src/main/libs/universal-image-loader-1.9.4.jar')     compile files('src/main/libs/javax.annotation-3.2-b06-sources.jar')     compile 'uk.co.chrisjenx:calligraphy:2.1.0'     compile 'com.squareup:otto:1.3.5'     compile 'com.google.android.gms:play-services:6.5.87'     compile 'com.android.support:support-annotations:23.0.1'     compile 'com.android.support:appcompat-v7:23.0.1'     compile 'com.android.support:support-v4:23.0.1'     compile 'com.android.support:palette-v7:23.0.1'     compile 'com.google.code.findbugs:jsr305:2.0.1'     compile 'com.nineoldandroids:library:2.4.0'     compile 'pl.charmas.android:android-reactive-location:0.4@aar'     compile 'io.reactivex:rxjava:1.0.3'     compile files('src/main/libs/FlurryAnalytics-6.1.0.jar')     compile 'com.github.castorflex.smoothprogressbar:library:1.1.0'        androidTestCompile 'com.android.support.test:testing-support-lib:0.1'     androidTestCompile'com.android.support.test:runner:0.4.1'     // Set this dependency to use JUnit 4 rules     androidTestCompile'com.android.support.test:rules:0.4'     // Set this dependency to build and run Espresso tests     androidTestCompile'com.android.support.test.espresso:espresso-core:2.2.1'     testCompile 'junit:junit:4.12'     testCompile "org.mockito:mockito-core:1.9.5" } 

My test (located in src/androidTest/java/lv/my/test)

package lv.my.test;  import android.support.test.rule.ActivityTestRule; import android.support.test.runner.AndroidJUnit4; import android.test.suitebuilder.annotation.LargeTest; import lv.my.android.activities.LoginActivity;  import org.junit.Before; import org.junit.Rule; import org.junit.Test; import org.junit.runner.RunWith;  @RunWith(AndroidJUnit4.class) @LargeTest public class LoginActivityTest {      private String mStringToBetyped;      @Rule     public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule<>(LoginActivity.class);      @Before     public void initValidString() {      }      @Test     public void changeText_sameActivity() { //        onView not recognized here      } } 

PS. I use roboguice could that be the issue?

Answer 1

You should either use a static import:

import static android.support.test.espresso.Espresso.onView; 

or

import android.support.test.espresso.Espresso; 

and call it in the following way

Espresso.onView() 

Answer 2

To extend what Egor has suggested, in Android Studio, once you get red text at onView(), simply press alt+enter when the red bulb popped up. Then choose static import.
