AOSP 中如何运行 robolectric

Question

我在 AOSP

中尝试运行 robolectric

我的 Android.bp 文件看起来像

android_robolectric_test {
    name: "MyRoboTests",

     srcs: [
             "src/**/*.java",
         ],

    static_libs: [
        "SettingsLib-robo-testutils",
        "android-support-annotations",
        "androidx.test.core",
        "androidx.test.runner",
        "androidx.test.ext.junit",
        "androidx.test.espresso.core",
    ],

    java_resource_dirs: ["config", "resources"],
    instrumentation_for: "MyProject",
    test_options: {
        timeout: 36000,
        shards: 10,
    },

    coverage_libs: [
        "Settings-core",
        "SettingsLib",
        "SettingsLib-search",
    ],
}

测试外观：

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.RobolectricTestRunner;

@RunWith(RobolectricTestRunner.class)
public class UsbTest {

    @Test
    public void test() {
        Object object = new Object();
        assertNotNull(object);
    }
}

我用atest运行试试

$ atest -c MyRoboTests

但测试没有运行。控制台外的外观：

Finding Tests...
Found 'MyUsbTest' as MODULE


Running Tests...
Run 'atest --history' to review test result history.

测试无效我不明白怎么了你能帮我运行ning robolectric for AOSP 吗？

Answer 1

经过调查，我发现 Robolectric 不是运行运行

In google source documentation 我找到了 link 自述文件：

If the change is submitted to AOSP, then a unit test is required. To get more information about how to write Robolectric based tests, see the readme file packages/apps/Settings/tests/robotests/README.md.

README.md

运行单次测试class

$ croot
$ make RunSettingsRoboTests ROBOTEST_FILTER=<ClassName>

所以在我的示例中，我的 Android.bp 文件

//############################################################
// Settings Robolectric test target.                         #
//############################################################
android_robolectric_test {
    name: "MyRoboTests",

     srcs: [
             "src/**/*.java",
         ],

    static_libs: [
        "SettingsLib-robo-testutils",
        "android-support-annotations",
        "androidx.test.core",
        "androidx.test.runner",
        "androidx.test.ext.junit",
        "androidx.test.espresso.core",
    ],

    java_resource_dirs: ["config", "resources"],
    instrumentation_for: "MyProject",
    test_options: {
        timeout: 36000,
        shards: 10,
    },

}

要创建命令，我需要将“运行”添加到模块名称“MyRoboTests”

$ make RunMyRoboTests ROBOTEST_FILTER=UsbTest

注意这个！

您应该更正 roblectrics 测试的创建文件夹结构，例如 this：

不要忘记“robotests”包中的“src”包。

在运行ning 测试后我得到输出：

============================================
[100% 10/10] build out/target/product/generic_car_x86_64/obj/ROBOLECTRIC/RunMyBoboRoboTests0_intermediates/test.fake
RunMyBoboRoboTests0: 
RunMyBoboRoboTests0: Time: 15.395
RunMyBoboRoboTests0: 
RunMyBoboRoboTests0: OK (12 tests)
RunMyBoboRoboTests0:

打开结果文件：

$ nautilus out/target/product/generic_car_x86_64/obj/ROBOLECTRIC/RunMyBoboRoboTests0_intermediates/

我希望这对某人有所帮助。编码愉快！
