Question

I need to test some function, that needs my application’s database and context.

I used to implement my testcase like this:

// TestCase is in the same package with tested module
package com.ircos.andromeda.utils;
...
// database operation classes
import com.ircos.andromeda.database.MeasurementDbAdapter; 
import com.ircos.andromeda.database.SessionDbAdapter;
import com.ircos.andromeda.database.domain.Measurement;
import com.ircos.andromeda.database.domain.Session;
import com.ircos.andromeda.exceptions.ExportException;

public class SessionExportHelperTestCase extends AndroidTestCase {
...

So, I thought context, retrieved by getContext() should return my application’s context and I’d be able to use the database just like from application itself.

But I failed. What am I doing wrong?

protected void setUp() {
    sessionDbAdapter.open(); // exception fires here!

…

public void open() throws SQLiteException {
    if (isOpen())
        return;

    this.open(new DatabaseManagementHelper(this.ctx)); // context is null!
}

Answer 1

Presumably, you have not assigned getContext() to this.ctx, and so this.ctx remains null.
