运行测试时出错，未在AndroidManifest.xml中指定目标包

Question

I am trying to run unit tests within an Android project within Android Studio. I have followed this tutorial on how to do so, it seems pretty straightforward. I have in AndroidManifest.xml declared as so

 <instrumentation
        android:name="android.test.InstrumentationTestRunner"
        android:targetPackage="tests" />

The tag is not inside an Activity, but is inside the

When I go to run the tests, I get the error

Test running failed: Unable to find instrumentation info for: ComponentInfo{com.example/android.test.InstrumentationTestRunner}

And that no tests were found.

So far I have only one test class I am trying to run, I believe this is set up correctly

public class ItemTests extends InstrumentationTestCase {

    private Item testItem = new Item("Car");
    public void testGetFoodItemName(){
        assertEquals("Car", testItem.getName());
    }

}

Any help would be fantastic! Thanks!

Answer 1

you can do the following to run tests.

add the following to build.gradle

android { 

    ....

    sourceSets {
        androidTest.setRoot('src/test')
    }

    ....
}

1) make a directory in src with name test as specified above.

2) further make a directory java inside test . You will notice color of java folder is green.

3) insider src/test/java/ you can put your ItemTests class and other classes.

4) Right click class ItemTests -> Run ItemTests -> Click ItemTests with android logo to run as android test case.
