Testing Sugar

[jivimberg]

Hi I was wondering if anyone was able to make sugar work with Robolectric.
I wrote a save tests and keep getting

java.lang.NullPointerException
    at dalvik.system.DexFile$DFEnum.hasMoreElements(DexFile.java:239)
    at com.orm.SugarDb.getDomainClasses(Unknown Source)
    at com.orm.SugarDb.createDatabase(Unknown Source)
    at com.orm.SugarDb.onCreate(Unknown Source)

    at android.database.sqlite.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:164)
    at com.orm.Database.openDB(Unknown Source)
    at com.orm.SugarRecord.save(Unknown Source)

Any pointer would be appreciated

+1 as well, Roboelectric is a great tool. I'll take a look into why this is happening within the next week.

I get the same error. My dependency is compile 'com.github.satyan:sugar:1.3' . what can I do?

I have the solution. Easy as hell.
You have to create a package com.orm with the class TestSugarApp. The Class looks like this:

@RunWith(RobolectricTestRunner.class)
@Config(manifest="./src/main/AndroidManifest.xml",emulateSdk=18)
public class TestSugarApp extends Application
    implements TestLifecycleApplication {



@Test
public void startEverTestSugarAppAsFirst() {

}

@Override
public void beforeTest(Method method) {
    Log.v("test", "beforeTest");
}

@Override
public void prepareTest(Object test) {
    Log.v("test", "prepareTest");
}

@Override
public void afterTest(Method method) {
    Log.v("test", "afterTest");
}
}

After that all tests worked out for me :)

Does it make sense to add a it as part of the Wiki. If yes, I can submit a pull request for the same.

[mlix11]

Make sense +1

I can do that, or ref to my post ;)

[leenasn]

ok. @loose11 are you taking care of the same?

[clay-to-n]

@loose11, I've created that package in test/java, and made that file (with imports and "package com.orm;" at the top) in my project.

I still get the same error, even in that new test file. On sugar 1.3.1. Using a custom Application class that extends SugarApp. Any idea what I could be missing?

[pickeyboy]

@loose11 I face exactly the same problem @clay-to-n is facing. Is there any solution ?

My Application class is also extending SugarApp and I get the same exception even after adding TestSugarApp under com.orm package.
