无法使用eclipse运行Robotium测试

Question

您好我已经使用robotium制作了测试脚本，但我无法运行它。应用程序安装在设备上但无法运行脚本。

查找脚本如下：

package com.crresearch.saywhat.test;

import com.crresearch.saywhat.ui.act.MainActivity;
import com.robotium.solo.Solo;

import android.test.ActivityInstrumentationTestCase2;

public class testUIactivity extends
        ActivityInstrumentationTestCase2<MainActivity> {


    private Solo solo; 

    public testUIactivity() {
        super("com.crresearch.saywhat", MainActivity.class);
        // TODO Auto-generated constructor stub
    }

    protected void setUp() throws Exception {
        super.setUp();
        solo = new Solo(getInstrumentation(), getActivity());

    }


    public void testSignUp() {
        //Unlock the lock screen
        solo.assertCurrentActivity("Check Main SCreen", MainActivity.class);
        solo.clickOnButton("Sign Up");


    }

}
