ReboletricSample工程搭建

受到 Just Say No to More End-to-End Tests

文章链接：http://googletesting.blogspot.tw/2015/04/just-say-no-to-more-end-to-end-tests.html

该文章启迪，决定对单元测试的内容稍做整理

Reboletric被测工程是Android Project，而测试工程是Java Project，执行的测试是Junit Test，并非Android Junit Test,跳过了模拟器，实现高效率运行

Reboletric官网：http://robolectric.org/getting-started/

工程环境Eclipse+maven(带M2Eclipse）插件

工程下载地址：

https://github.com/priyaaank/RobolectricSample

环境中，maven版本为3.1.1（需要根据情况更新到新版本）；

robolectric包版本为：robolectric-2.4-jar-with-dependencies.jar

下载地址： https://repo1.maven.org/maven2/org/robolectric/robolectric/2.4/

M2Eclipse推荐安装方式：
插件方式，Help-Install new Software- 输入以下地址，
http://download.eclipse.org/technology/m2e/releases/

RobolectricSample示例工程

1.下载示例工程
2.命令行下切换到工程目录，执行android update project -p . --target 1
(--target指定android的api level，android list命令可查询)
3.import 导入示例工程
4.配置build path，添加robolectric-***-jar-with-dependencies.jar包；
添加<your android install directory>/add-ons/addon-google_apis-google-**/libs/maps.jar

关于Google Maps API maps.jar file for android

First of all update your SDK->Google Play Services and then

Find this Path in your Computer :

...android-sdk-windowsadd-onsaddon-google_apis-google-17libsmaps.jar

add this jar using Add External Jar...

导入包后的build path路径下如图所示：

5.右键test下工程，Right-click -> Run As ->JUnit Test

会提示如下对话框：

点击OK取消后，会弹出一个配置的对话框

下载Android.jar

地址：http://www.java2s.com/Code/Jar/a/Downloadandroidjar.htm

配置Run Configuration，Right-click -> Run As -> Run Configurations
Tab: Classpath -> User Entries -> Add External JARs ...
找到android.jar

7.运行测试用例；右键点击测试用例，选择Run As -> Junit Test

执行后查看结果：

HttpTest.java这个case中导入的包

import com.google.inject.internal.Maps;

查到存在此文件的JAR包：

com.google.inject.internal.Maps.java

http://www.java2s.com/Code/Jar/g/Downloadguicepatches214sourcesjar.htm

执行mvn clean test后提示找不到com.google.inject.internal

笔者改为：

import com.google.inject.internal.util.$Maps;

com.google.inject.internal.util

com.google.inject.internal.util.Maps

http://bornjohannes-codex.eclipselabs.org.codespot.com/git/Imports/index.html?com/google/inject/internal/util/package-tree.html

执行后成功

可能遇到的问题：

1.Project build error: Unknown packaging: apk
在Eclipse中安装m2e-android插件

安装源:http://download.eclipse.org/technology/m2e/releases/
安装方法:Help -> Install new Software -> 在出来的对话框中点击 Add ->
Name:m2e-android
若m2e装好后仍未解决，检查Maven配置

Windows—>Preferences—>Maven—>User Settings，查看setting.xml
确保这里的Maven不是用的Eclipse自带的，而是本地下载的新版本的Maven

2.mvn clean install 报错：

Failure to find org.springframework:spring:jar:3.0.0.RELEASE in http://download.java.net/maven/2/ was cached in
the local repository, resolution will not be reattempted until the update interval of Java.Net has elapsed or updates are forced -> [Help 1]

解决办法：
Not sure if this works for Maven 3, here's what would work for Maven 2. This should work to clean the local repository:

mvn dependency:purge-local-repository
Otherwise, try cleaning the specific artifact from your local repository:

* Linux: ~/.m2
* Windows: C:Documents and SettingsUSER.m2

另外见上两篇博文maven的两个坑：

3.http://www.cnblogs.com/melody-emma/p/5112658.html

4.http://www.cnblogs.com/melody-emma/p/5112722.html

5.@Override 的代码全部都报错

默认Maven中的JAVA版本是1.5,只要修改成1.6就好了

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>2.1</version>
  <configuration>
    <source>1.6</source>
    <target>1.6</target>
  </configuration>
</plugin>

希望本文能帮助你不再被坑
