Android单元测试不起作用

嘿嘿,

我是Android测试新手。我尝试使用editText编写两个数字相乘的测试。它似乎没有运行，并且在emulator上没有显示任何内容。我的测试代码如下

import android.test.ActivityInstrumentationTestCase2;

import com.example.calculator.MainActivity;
import com.jayway.android.robotium.solo.Solo;

public class MathValidation extends ActivityInstrumentationTestCase2<MainActivity> {

    private Solo solo;
    public MathValidation() {
        super(MainActivity.class);
    }

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

    protected void tearDown() throws Exception {
        solo.finishOpenedActivities();
    }
    public void Test() throws Exception{
        solo.assertCurrentActivity("wrong activity", MainActivity.class);
        solo.enterText(0, String.valueOf("10"));
            solo.enterText(1,String.valueOf("30"));
        solo.clickOnButton("Multiply");
        assertTrue(solo.searchText("300"));


    }

所有这些显示的都是代码，而不是您实际运行测试的方式。您是从Eclipse还是从命令行运行它？不管怎样，这将有助于了解您所遵循的确切步骤

另外，Solo是一项活动吗？

在大多数测试框架中，测试方法的名称必须以

test

开头。方法名称区分大小写，因此问题是您的方法被称为

Test（）

，而不是

Test（）

。这就是为什么它没有运行

Java中的标准编码约定使用以小写字母开头的方法名称。此外，您通常希望为测试提供更多描述性名称，例如，

testMultiply（）

Solo是运行Robotium自动化测试时使用的助手。
