使用 Robolectric 运行 Android 测试 - 依赖错误

Question

I am using Android Studio 1.2 and Windows 7

When running a robolectric test following this example :

@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 {

    }
}

test result or more the error stacktrace:

    Unable to resolve artifact: Unable to get dependency information: Unable to read the metadata file for artifact 'org.robolectric:android-all:jar': Cannot find parent: org.sonatype.oss:oss-parent for project: org.robolectric:android-all:jar:5.0.0_r2-robolectric-1 for project org.robolectric:android-all:jar:5.0.0_r2-robolectric-1

I find out that the resource, robolectric try to get ,is not avaible. When following the url it trys to get it: https://oss.sonatype.org/content/groups/public/org/sonatype/oss/oss-parent/

there is no oss 7. Why does robolectrics try to get a resource that is not there? And how to get it to work?

Answer 1

This seems to be a proxy problem. When behind proxy you have to specify proxy settings for maven at {userHome}/.m2/settings.xml

my settings.xml looks now like:

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

below not working !!

<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>

I've been able to fix the same issue by overriding Robolectric Maven repository URL.

Sonatype is not available for some reason and Maven Central moved to HTTPS starting from Jan 15, 2020. So, I've decided to use Maven Central URL but with a secure scheme.

Editing the system property which is used by Robolectric RoboSettings class allowed me to use a different URL.

android {
    testOptions {
        unitTests.all {
            systemProperty 'robolectric.dependency.repo.url', 'https://repo1.maven.org/maven2'
        }
    }
}

I had this error when i run the Robolectric tests with JRE 11.

Going to Run/Debug Configurations and change it to JRE 1.8 may fix your problem.

Step 1: Run/Debug Configurations

Step 2: Change JRE
