使用Robolectric运行Android测试 - 依赖错误

androidrobolectric
6

我正在使用Android Studio 1.2和Windows 7。

按照这个示例运行robolectric测试时：

@RunWith(CustomRobolectricRunner.class)
@Config(emulateSdk = 21, reportSdk = 21, constants = BuildConfig.class)
public class PasswordProviderTest{

    @Test
    public void testGetPassword() throws Exception {
        Activity activity = Robolectric.setupActivity(LoginActivity.class);
    }

    @Test
    public void testSetPassword() throws Exception {

    }
}

测试结果或错误堆栈跟踪：

Gradle 构建依赖关系：

testCompile 'junit:junit:4.12'
testCompile "org.mockito:mockito-core:1.9.5"
testCompile 'org.apache.maven:maven-ant-tasks:2.1.3'
testCompile "org.robolectric:robolectric:3.0-rc2"

我发现robolectric尝试获取的资源不可用。当跟随它尝试获取它的URL时：https://oss.sonatype.org/content/groups/public/org/sonatype/oss/oss-parent/，并没有oss 7。为什么robolectric会尝试获取一个不存在的资源？如何使其正常工作？
我猜这是 Robolectric 用来进行真实测试的 AOSP jar 包。 - Eugen Martynov
这对我的问题意味着什么？ - Visores
啊，抱歉我理解成了“为什么它在下载不在我的build.gradle文件中的依赖项”。而这个依赖项实际上是可以通过Maven中央仓库获取的（http://search.maven.org/#artifactdetails%7Corg.sonatype.oss%7Coss-parent%7C7%7Cpom）。所以可能你有防火墙或代理问题。 - Eugen Martynov
是的，我有一个无法移除的代理......但我还说过，当查找资源时，该资源不存在。 - Visores
它在Sonatype仓库中不存在，但在Maven中央仓库中存在。 - Eugen Martynov

这似乎是代理问题。当您在代理后面时，您需要在 {userHome}/.m2/settings.xml 中指定 Maven 的代理设置。

我的 settings.xml 现在看起来像这样：

<settings>
    <proxies>
        <proxy>
            <active>true</active>
            <host>proxy.host</host>
            <port>3128</port>
        </proxy>
    </proxies>
</settings>

以下代码无法正常工作!!

<settings>
    <proxies>
        <proxy>
            <id>proxy-https</id>
            <active>true</active>
            <protocol>https</protocol>
            <host>proxy.host</host>
            <port>3128</port>
        </proxy>
        <proxy>
            <id>proxy-http</id>
            <active>true</active>
            <protocol>http</protocol>
            <host>proxy.host</host>
            <port>3128</port>
        </proxy>
    </proxies>
</settings>
你弄明白了吗？测试现在能运行了吗？ - Jared Burrows
也许有人能告诉我为什么第一个有效而第二个无效...？ - Visores
如果你曾经创建过一个“集成”测试，并且必须在代理后面使用HTTP请求，请发布另一个有帮助的答案！ - Jared Burrows
我使用的是Robolectric 3.0版本，依赖的jar包是从我的仓库下载的，而不是从sonatype下载的。 - Surekha

当我使用JRE 11运行Robolectric测试时，出现了这个错误。

前往“运行/调试配置”并将其更改为JRE 1.8可能会解决您的问题。

步骤1： 运行/调试配置

步骤2： 更改JRE

我已经通过覆盖Robolectric Maven存储库URL来解决相同的问题。

由于某种原因，Sonatype不可用，而Maven Central从2020年1月15日开始转移到HTTPS。因此，我决定使用Maven Central URL，但使用安全方案。

编辑Robolectric RoboSettings类使用的系统属性允许我使用不同的URL。

android {
    testOptions {
        unitTests.all {
            systemProperty 'robolectric.dependency.repo.url', 'https://repo1.maven.org/maven2'
        }
    }
}
它仅适用于Robolectric 4.0+，请检查此提交以添加这些系统属性： https://github.com/robolectric/robolectric/commit/5f85c0dcd3642950c458864accf6fea67265f3da#diff-258d2ffac3be70a232b114e76e80588d - Paweł

@Pawel那不正确。您的提交添加了其他属性，但是该问题中的属性在4年前的3.1版中添加：https://github.com/robolectric/robolectric/commit/d56f48b520427488f7d406d295cf7bc5ecd12925 - colriot

它对我不起作用。仍然尝试从Sonatype下载并失败的安卓工作室。 正在从位于https://oss.sonatype.org/content/groups/public/的存储库sonatype下载：org/robolectric/android-all/4.1.2_r1-robolectric-r1/android-all-4.1.2_r1-robolectric-r1.pom 传输文件时出错：连接超时：连接 [警告] 无法从存储库sonatype（https://oss.sonatype.org/content/groups/public/）获取资源'org.robolectric:android-all:pom:4.1.2_r1-robolectric-r1'：传输文件时出错：连接超时：连接 - Sandeep Cg

@SandeepCg 几个小时前也遇到了同样的问题，但现在已经恢复正常了。我执行了两次测试，都成功通过了。看起来是与 Sonatype 仓库的临时连接问题有关，呵呵。 - RAM237
