好吧，其实我也不怎么会，别人一边说我一边写的~~~

1、首先是配置环境

如果本身配置高，会自动的配置测试环境

2、xml布局
<TextView

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello Word"
    android:id="@+id/textView" />


<EditText

    android:hint="Enter your name here"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/editText"
    android:layout_alignBaseline="@+id/button"
    android:layout_alignBottom="@+id/button"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />

<Button

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Say Hello"
    android:id="@+id/button"
    android:layout_below="@+id/textView"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_marginTop="51dp" />

3、MainActivity

package com.example.lenovo.myapplication1;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    private TextView textView;

    private EditText editText;

    private Button button;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);



        textView= (TextView) findViewById(R.id.textView);

        editText= (EditText) findViewById(R.id.editText);

        button= (Button) findViewById(R.id.button);



        button.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                editText.setText(textView.getText().toString());

            }

        });

    }

}

4、测试程序

private static final String STRING_TO_BE_TYPED = "Peter";

、、、

package com.example.lenovo.myapplication1;

import org.junit.Rule;
import org.junit.Test;

/**
 * Created by lenovo on 2017-3-16.
 */
@Rule
public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(MainActivity.class);

@Test
public void sayHello() {
        onView(withId(R.id.editText))
        .perform(typeText(STRING_TO_BE_TYPED),
        closeSoftKeyboard());

        onView(withText("Say hello!")).perform(click());

        String expectedText = "Hello," + STRING_TO_BE_TYPED + "!";
        onView(withId(R.id.textView))
       .check(matches(withText(expectedText)));
        }
结束
