Espresso: How to use R.string resources of androidTest folder

Question

I want to put data in xml file of androidTest/res/values/string.xml folder. I have created the file say test.xml with below contents.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="test">hello</string>
</resources>

When i am trying to access the field test via R.string.test. It is not accessible and says "cannot resolve symbol test". Can someone please advice me here.

Answer 1

androidx.test.platform.app.InstrumentationRegistry is deprecated use androidx.test.core.app.ApplicationProvider

val targetContext = ApplicationProvider.getApplicationContext<Context>()
val test: String =  targetContext.resources.getString(R.string.test)

Answer 2

This is how you do it:

import com.my.example.test.R;

Resources resources = InstrumentationRegistry.getContext().getResources();
String terms = resources.getString(R.string.test);
