32 * Use this to inject a {@link Context} representing {@link Instrumentation#getTargetContext()}
33 * into your JUnit4-style test.
34 * <p/>
35 * To use, just add the correct annotation to an {@link Context} field like this:
36 * <pre>
37 *     &#64;InjectContext public Context mMyContext;
38 * </pre>
39 * The test runner will set the value of this field with the {@link Instrumentation} after
40 * object construction but before any {@link Before} methods are called.
41 * <p/>
42 * Declaring this in a JUnit3 test (ie a class that is a {@link Test}) will have no effect.
43 * Use {@link AndroidTestCase} instead for JUnit3 style tests.
