Plugin Route

Trying this plugin: https://github.com/kageiit/gradle-robojava-plugin

I am starting from a Blank Activity wizard hello world project - nothing fancy. I stashed by attempts at the manual configuration route that I was pursuing yesterday.

Added tdd module

Used the drop down menu, selected Java at the very bottom.

settings.gradle (top-level)

Confirmed that Android Studio updated with both modules.

include ':app', ':tdd'

app/build.gradle

Applied robolectric plugin to the module app.

apply plugin: 'robolectric'

Added dependencies:

dependencies {
    ...
    androidTestCompile 'junit:junit:4.12'
    androidTestCompile('org.robolectric:robolectric:2.4') {
        exclude group: "commons-logging", module: "commons-logging"
        exclude group: "org.apache.httpcomponents", module: "httpclient"
    }
}

Configured Robolectric to look for the test files.

robolectric {
    include "com/greenlifesoftware/**/*Test.class"
}

Final file:

apply plugin: 'com.android.application'
apply plugin: 'robolectric'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.greenlifesoftware.calculator"
        minSdkVersion 12
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    androidTestCompile 'junit:junit:4.12'
    androidTestCompile('org.robolectric:robolectric:2.4') {
        exclude group: "commons-logging", module: "commons-logging"
        exclude group: "org.apache.httpcomponents", module: "httpclient"
    }
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
}

robolectric {
    include "com/greenlifesoftware/**/*Test.class"
}

tdd.gradle

Replaced the default/template text in the module text with this:

evaluationDependsOn(':app')
ext.androidProject = 'app'
apply plugin: 'com.kageiit.robojava'

build.gradle (top-level)

Added the plugins to the classpath.

dependencies {
    ...
    classpath 'com.kageiit:robojava-plugin:1.0.0'
    classpath 'org.robolectric:robolectric-gradle-plugin:0.14.+'
}

Final state:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
        classpath 'com.kageiit:robojava-plugin:1.0.0'
        classpath 'org.robolectric:robolectric-gradle-plugin:0.14.+'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Run

Note: Running what ever the default Android project configuration is as well as the default module creation - except for the changes mentioned above. The new AS project wizard creates an androidTest folder when you create a project.

./gradlew tdd check

Error, doesn't know where to find Android.

java.lang.RuntimeException: Stub!

Guessing since tdd is really a stub.

Create Test

Created a Robolectric test in addition to the default ApplicationTest that comes with the wizard.

Used the shortcut Command Shift T to create a test, selected junit 4.

File location: .../Calculator/app/src/androidTest/java/com/greenlifesoftware/calculator/CalculatorActivityTest.java

Test file:

package com.greenlifesoftware.calculator;

import android.app.Activity;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;

import static org.junit.Assert.*;

@RunWith(RobolectricTestRunner.class)

public class CalculatorActivityTest {
    @Test
    public void shouldNotBeNull() throws Exception {
        Activity activity = Robolectric.buildActivity(CalculatorActivity.class).create().get();
        assertNotNull(activity);
    }
}

Run Test: AS

Right clicking on the file name (either the text or the tab at the top) to create a run configuration. When I run this configuration, I get this error:

Process finished with exit code 255

Why doesn't AS know where my AndroidManifest.xml is located? In other integration versions, we created a test runner to point to it. I don't see that happening in the example project - it uses the default one.

Run Test: Command Line

I didn't see anywhere that emulateSDK is used to go back to API level 18 (top level supported by Robolectric). Was this buried in the other plugin's code somewhere?

More Research

Rereviewing the README and example project for clues.

Note: The project structure dialog shown is different for the latest version of Android Studio. I'm running 1.0.1. I'm not a huge fan of the view - it makes it harder to understand where the files live on disk.

Current state of my app.gradle:

apply plugin: 'com.android.application'
apply plugin: 'robolectric'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.greenlifesoftware.calculator"
        minSdkVersion 12
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    androidTestCompile 'junit:junit:4.12'
    androidTestCompile('org.robolectric:robolectric:2.4') {
        exclude group: "commons-logging", module: "commons-logging"
        exclude group: "org.apache.httpcomponents", module: "httpclient"
    }
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
}

robolectric {
    include "com/greenlifesoftware/**/*Test.class"
}

I don't see any differences here. The project structure matches. Not sure what I'm missing here. Will research the error show about about API level 21.

API Level 21

java.lang.UnsupportedOperationException: Robolectric does not support API level 21, sorry!

Maybe their project strucutre didn't extend the new stuff like the new wizard might? Turns out they have zero resources for this example project. Are they not extending a theme in AndroidManifest.xml? No theme:

<application android:name=".RobojavaApplication">

<activity
    android:name=".RobojavaActivity"
    android:screenOrientation="portrait">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

    </application>

Clue: http://stackoverflow.com/questions/20541630/robolectric-does-not-support-api-level

Added emulateSDK. Final test class:

package com.greenlifesoftware.calculator;

import android.app.Activity;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;

import static org.junit.Assert.*;

@Config(emulateSdk = 18)
@RunWith(RobolectricTestRunner.class)

public class CalculatorActivityTest {
    @Test
    public void shouldNotBeNull() throws Exception {
        Activity activity = Robolectric.buildActivity(CalculatorActivity.class).create().get();
        assertNotNull(activity);
    }
}

Noticed app/build/intermediates/res/debug/layout/abc_screen_toolbar.xml in the stacktrace, went to source.

Ok, so the wizard uses ActionBarActivity as the base for the "Blank Activity" type of project from the wizard.

Since this not needed for my project, it would be helpful for other projects in the future. Changing to a normal Activity base so it isn't so cranky.

Changed:

public class CalculatorActivity extends ActionBarActivity {}

to

public class CalculatorActivity extends Activity {}

Run from AS

Using a gradle task (side bar) for check. Equivalent should be ./gradlew check on the command line.

Still getting an failure:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:testDebug'.
> There were failing tests. See the report at: file:///Users/colabug/AndroidStudioProjects/Calculator/app/build/test-report/debug/index.html

Weird there were only warnings in the report and it reported that 33% of my tests passed: 3 tests, 2 failures.

Removed Default Tests

Removed what AS included by default.

Reran the gradle check task:

1 test completed, 1 failed
:tdd:test FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':tdd:test'.
> There were failing tests. See the report at: file:///Users/colabug/AndroidStudioProjects/Calculator/tdd/build/reports/tests/index.html

Opened my test report and it says everything passes.

Clean up Test module

When I created the test module, it included tdd/java/com/example/Tests.java as part of the module creation wizard. Deleting the src directory and child files.

Run gradle task again. Failure:

:tdd:test

com.greenlifesoftware.calculator.CalculatorActivityTest > shouldNotBeNull FAILED
    android.content.res.Resources$NotFoundException at CalculatorActivityTest.java:19

Blah

If you are running all tests via check, might as well just use testDebug or app:check

The robojava plugin is mainly meant for running these tests inside AS/debug and running sets of tests on the commandline. I will add a more complete/complex example today
