Android2.1--robotium<2>--AndroidCalculator

AndroidCalculator 这是一个官网上的例子

1--首先介绍一下robotium 我的简单理解就是，可以模拟人对android设备的操作，点击，向文本框中输入内容之类的... ...

　 使用robotium，就是通过调用测试类Solo提供的一些方法，对android进行测试的

2--安装robotium

　 安装robotium，其实就是导入包含Solo类的jar包

　 下载地址：http://code.google.com/p/robotium/downloads/list，到上面下载一个适用于你androidAPI级别的版本

　 我用的是android2.1 ，下载的是robotium-solo-2.1.jar

　 下载完成后，不用解压，等着什么时候用，引入这个jar就完了

3--建立一个android工程AndroidCalculator  一个简单的计算器，只实现一种运算--乘法，

layout.xml

        android:id="@+id/Button01"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/> 

</LinearLayout>

string.xml

<resources>

    <string name="app_name">AndroidCalculator</string>

AndroidCalculatorActivity.java

package com.calculator;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.text.Editable;
import android.widget.TextView;
import android.widget.EditText;
import android.widget.Button;
import android.view.View;

public class AndroidCalculatorActivity extends Activity 
{
    EditText FirstValue;
    EditText SecondValue;
    TextView Result;
    Button Calculate;
    float num1, num2;
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_android_calculator);
        
        FirstValue = (EditText)findViewById(R.id.EditText01);
        SecondValue = (EditText)findViewById(R.id.EditText02);
        
        Result = (TextView)findViewById(R.id.TextView01);
        Result.setTag("0.00");
        Calculate = (Button)findViewById(R.id.Button01);
        Calculate.setOnClickListener(new View.OnClickListener() 
        {
            @Override
            public void onClick(View v) 
            {
                // TODO Auto-generated method stub
                showResult(FirstValue.getText(),SecondValue.getText());
            }
        });
    }
    
    //showing results
    protected void showResult(Editable first, Editable second)
    {
        float num1 = Float.parseFloat(first.toString());
        float num2 = Float.parseFloat(second.toString());
        float result = num1*num2;
        Result.setText(String.valueOf(result));
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_android_calculator, menu);
        return true;
    }
}

4--建立一个测试工程 AndroidCalculatorTest
　　创建一个测试工程才是重点，File --> New --> Project --> Android Project --> Android Test Project

　　将AndroidCalculator选为Select Test Target

　　在AndroidCalculatorTest-->右键-->build path-->Configure Build Path…

然后点击Add External JARs…按钮，导入本机中的robotium-solo-2.1.jar文件，最后点击Order and Export ，把所有的选项都勾上

添加一个TestMain.java

import android.test.ActivityInstrumentationTestCase2;
import com.jayway.android.robotium.solo.Solo;

package com.calculator.test;

import java.util.ArrayList;
import android.test.ActivityInstrumentationTestCase2;
import android.widget.EditText;
import android.widget.TextView;
import com.calculator.R;
import com.jayway.android.robotium.solo.Solo;
import com.calculator.AndroidCalculatorActivity;

public class TestMain extends ActivityInstrumentationTestCase2<AndroidCalculatorActivity>
{
    private Solo solo;
    public TestMain()
    {
        super("com.calculator",AndroidCalculatorActivity.class);
    }
    
    @Override
    protected void setUp() throws Exception
    {
        super.setUp();
        solo = new Solo(getInstrumentation(), getActivity()); 
    }
    
    public void testDisplayBlackBox()
    {
        solo.enterText(0, "10");
        solo.enterText(1, "20");
        solo.clickOnButton("Multiply");
        assertTrue(solo.searchText("200"));
    }
    
    public void testDispalyWhiteBox()
    {
        float firstNumber = 10;
        float secondNumber = 20;
        float result = firstNumber*secondNumber;
        EditText FirsteditText = (EditText) solo.getView(R.id.EditText01); 
        solo.enterText(FirsteditText, String.valueOf(firstNumber)); 
         
        //Access Second value (editfiled) and putting SecondNumber value in it 
        EditText SecondeditText = (EditText) solo.getView(R.id.EditText02); 
        solo.enterText(SecondeditText, String.valueOf(secondNumber)); 
        solo.clickOnButton("Multiply");
        
        assertTrue(solo.searchText(String.valueOf(result))); 
        
        TextView outputField = (TextView)solo.getView(R.id.TextView01); 
         
        ArrayList currentTextViews = solo.getCurrentTextViews(outputField); 
        assertFalse(currentTextViews.isEmpty()); 
         
        TextView output = (TextView) currentTextViews.get(0); 
         
        //Assert to verify result with visible value 
        assertEquals(String.valueOf(result), output.getText().toString()); 
      } 
       
    @Override 
      protected void tearDown() throws Exception
      { 
        try
        {
            solo.finalize();
        }
        catch(Throwable e)
        {
            e.printStackTrace();
        }
        getActivity().finish();
        super.tearDown();
         
      }

}
