Test running failed: Unable to find instrumentation info for: ComponentInfo{} -- error trying to test in IntelliJ with Gradle
android, android-testing, gradle
Solution
So the main problem was that when I created an androidTest folder under /src/, it wasn't being picked up by IntelliJ as a source folder for testing (java subdirectory should turn green). I was using IntelliJ 13.0.3 and after upgrading to 13.1.3, all of my troubles went away.
*Note: do not try to add a manifest to your androidTest folder, the Gradle docs specifically state that the manifest should be auto-generated when you create the androidTest folder. The problem for me was that the file wasn't being generated as androidTest wasn't being recognized by IntelliJ/Gradle, thus throwing the no instrumentation error.
Problem
Everytime I try to run my tests the console says this: ``` Running tests Test running startedTest running failed: Unable to find instrumentation info for: ComponentInfo{com.employeeappv2.employeeappv2.test/android.test.InstrumentationTestRunner} Empty test suite. ``` I've been stuck on this for a while and the solutions I've seen online so far have not helped. My project structure is set up like this: *Main Module -src *instrumentTest -java *main -java -manifest *build.gradle My build.gradle file looks like this: ``` buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.9.+' } } apply plugin: 'android' repositories { mavenCentral() } android { compileSdkVersion 19 buildToolsVersion "19.1.0" defaultConfig { minSdkVersion 16 targetSdkVersion 19 versionCode 1 versionName "2.1.0" testPackageName "login.test" testInstrumentationRunner "android.test.InstrumentationTestRunner" } buildTypes { release { runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard- rules.txt' } } packagingOptions { exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' exclude 'META-INF/notice.txt' exclude 'META-INF/license.txt' } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile files('libs/scandit.zip') compile project(':pullToRefresh') compile 'com.android.support:appcompat-v7:19.+' compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.1+' compile 'org.springframework.android:spring-android-rest-template:1.0.1+' compile 'org.json:json:20090211' compile 'com.fasterxml.jackson.core:jackson-databind:2.3.1' compile 'com.fasterxml.jackson.core:jackson-annotations:2.3.0' compile 'com.fasterxml.jackson.core:jackson-core:2.3.1' compile 'com.android.support:support-v4:19.1.+' compile 'com.mcxiaoke.volley:library:1.0.+@aar' androidTestCompile 'junit:junit:3.8' } ``` Do you need to have a separate manifest for your tests directory? If so what would that look like? Edit: I tried adding a manifest to my instrumentTest directory with no luck. Note that I could not get IntelliJ to resolve the targetPackage name, so it appears red. ``` <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.employeeappv2.employeeappv2.src.instrumentTest" android:versionCode="1" android:versionName="1.0.0"> <application> <uses-library android:name="android.test.runner" /> </application> <instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="com.employeeappv2.employeeappv2.src.main"/> </manifest> ```
