Test running failed: Permission Denial: starting instrumentation ComponentInfo

Question

Test running failed:

Permission Denial: starting instrumentation ComponentInfo{com.xxx.taskmanager.warehouse.tests/android.test.InstrumentationTestRunner} from pid=766, uid=766 not allowed because package com.xxx.taskmanager.warehouse.tests does not have a signature matching the target com.xxx.taskmanager.warehouse

Empty test suite.

This is my app.gradle file

apply plugin: 'android-sdk-manager'
apply plugin: 'com.android.application'

android {
    signingConfigs {
        release
        {

        }
    }

    variantFilter { variant ->

    }
}

}

task copyTask(type: Copy) {
    from 'build/outputs/apk'
    into 'apks'
    exclude '**/*-unaligned.apk'
}

task deleteApk(type: org.gradle.api.tasks.Delete){
    //    delete 'apks'
}

task appBuild(dependsOn: ['deleteApk','clean', 'assembleRelease',       'copyTask']){
    assembleRelease.mustRunAfter deleteApk
    clean.mustRunAfter deleteApk
    copyTask.mustRunAfter assembleRelease
}

I think this error is happening because I have not declared the signingConfigs for test package. If so , how do I declare it. ?

Please help!!

Answer 1

I have solved the issue. Answering it so that it can be useful for someone else.
Solution is for Android Studio :
For the tests to run , the build variant should be debug. Build Variants window is present in the left side of the android studio, if not activated then activate it by click on Build variants tab present on the left side of the android studio.
