Android單元測試包路徑錯誤

Question

我一直在與Android單元測試一起插入，並遇到了似乎是路徑問題。

首先我在我的項目目錄

android create test-project -m ../ -p tests -n RoamPayTests 

這將創建一個測試項目，並初始化它內運行從我的這個命令。自動生成的ActivityInstrumentaionTestCase2工作正常。 我可以在這裏創建測試，一切正常。

注意：請注意，主要活動在ui包中。

package com.roamdata.roampayx; 

import com.roamdata.roampayx.ui.SplashActivity; 

import android.test.ActivityInstrumentationTestCase2; 

/** 
* This is a simple framework for a test of an Application. See 
* {@link android.test.ApplicationTestCase ApplicationTestCase} for more information on 
* how to write and extend Application tests. 
* <p/> 
* To run this test, you can type: 
* adb shell am instrument -w \ 
* -e class com.roamdata.roampayx.ui.SplashActivityTest \ 
* com.roamdata.roampayx.tests/android.test.InstrumentationTestRunner 
*/ 
public class SplashActivityTest extends ActivityInstrumentationTestCase2<SplashActivity> { 

    public SplashActivityTest() { 
     super("com.roamdata.roampayx", SplashActivity.class); 
    } 

這裏產生Android_Manifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<!-- package name must be unique so suffix with "tests" so package loader doesn't ignore us --> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
      package="com.roamdata.roampayx.tests" 
      android:versionCode="1" 
      android:versionName="1.0"> 
    <!-- We add an application tag here just so that we can indicate that 
     this package needs to link against the android.test library, 
     which is needed when building test cases. --> 
    <application> 
     <uses-library android:name="android.test.runner" /> 
    </application> 
    <!-- 
    This declares that this application uses the instrumentation test runner targeting 
    the package of com.roamdata.roampayx. To run the tests use the command: 
    "adb shell am instrument -w com.roamdata.roampayx.tests/android.test.InstrumentationTestRunner" 
    --> 
    <instrumentation android:name="android.test.InstrumentationTestRunner" 
        android:targetPackage="com.roamdata.roampayx" 
        android:label="Tests for com.roamdata.roampayx"/> 
</manifest> 

汽車的問題是，當我嘗試創建一個新的測試用例。

package com.roamdata.roampayx; 
import com.roamdata.roampayx.provider.RoamPay; 
import com.roamdata.roampayx.provider.RoamPayProvider; 
import android.test.ProviderTestCase2; 


public class ProviderTest extends ProviderTestCase2<RoamPayProvider> { 
    public ProviderTest() { 
     super(RoamPayProvider.class, RoamPay.AUTHORITY); 
    } 
} 

接下來我建立並安裝，（這裏沒有問題）。但後來我跑

adb shell am instrument -w com.roamdata.roampayx.tests/android.test.InstrumentationTestRunner 

，最後我得到以下錯誤

android.test.suitebuilder.TestSuiteBuilder$FailedToCreateTests:

我有進口RoamPay和RoamPayProvider。 智能感知正在工作，我得到這些參考。

任何想法？

Answer 1

除構造函數外，一切都很好。我改成

public RoamPayProviderTest() { 
    super(RoamPayProvider.class, "com.roamdata.roampayx"); 
} 

現在一切正常。我想你可以使用這個問題和答案作爲一個很好的教程，如何設置你的單元測試。
