私はAndroidのテストに関する本をフォローしていて、このサンプルを実装しています。
public class TemperatureConverterActivityTests extends
ActivityInstrumentationTestCase2<TemperatureConverterActivity> {
private TemperatureConverterActivity mActivity;
private EditText mCelsius;
private EditText mFarenheit;
public TemperatureConverterActivityTests() {
this("TemperatureConverterActivityTests");
}
public TemperatureConverterActivityTests(String name) {
super(TemperatureConverterActivity.class);
setName(name);
}
protected void setUp() throws Exception {
super.setUp();
mActivity = getActivity();
mCelsius = (EditText) mActivity
.findViewById(org.mighter.tc.R.id.celsius);
mFarenheit = (EditText) mActivity
.findViewById(org.mighter.tc.R.id.farenheit);
}
protected void tearDown() throws Exception {
}
public final void testPreconditions() {
assertNotNull(mActivity);
}
public final void testHasInputFields() {
assertNotNull(mCelsius);
assertNotNull(mFarenheit);
}
}
ただし、テストは終了しません。

デバッグを試みましたが、testPreconditions（）に到達しません。ありがとう。
