Spectatio 是一个开源测试框架，用于在真实和虚拟设备上测试 Android Automotive OS (AAOS)。 Spectatio 提供用于在汽车设备上测试应用程序的 API，是一种可扩展和可扩展的解决方案，用于验证 AAOS 及其应用程序的功能和性能。
高级设计
Spectatio 框架对各种 AAOS UI 实现具有适应性和可扩展性。它用于在设备硬件、模拟器和虚拟化环境中测试 AAOS 的功能和性能。
下图解释了 Spectatio 框架的高级设计。
图 1. Spectatio 框架高层设计
Spectatio 框架建立在UI Automator之上，提供了一组 API 来构建与 AAOS 上的用户和系统应用程序交互的 UI 测试。汽车测试使用 Spectatio 框架提供的 API 进行测试，这使得这些测试独立于被测设备 (DUT) 并且可扩展以测试各种设备（如果支持）。
图 1 显示 Spectatio 框架是基于参考应用程序（例如 Dialer、Medicenter 和 Settings）使用应用程序特定的接口和帮助程序进行模块化的，使其易于扩展以用于新应用程序。 Spectatio 框架重用了通用的标准和实用程序助手类。标准助手类是所有应用程序助手函数的父类，并提供特定于设备或适用于应用程序的标准函数。实用程序助手类提供实用程序，例如从设备读取或写入文件。
建筑学
为了提供一组 API 来构建 UI 测试，Spectatio 框架在扩展现有的标准帮助程序类和导入实用程序帮助程序类的同时，实现了特定于应用程序的接口和帮助程序。
下图解释了 Spectatio 框架的高级架构以及实现 API 以测试应用程序所涉及的所有实体。
图 2. Spectatio 框架高层架构
应用程序助手接口为应用程序助手的实现提供了蓝图。它由测试应用程序所需的各种帮助函数组成。每个应用程序都有自己的接口，例如IAutoSettingHelper和IAutoDialHelper 。有关更多信息和接口函数列表，请参阅 AOSP 上的应用程序助手接口函数。
标准助手类由设备设置所需的标准属性和函数组成，但并不特定于任何应用程序，例如pressHome和scroll 。标准助手类在AbstractAutoStandardAppHelper.java中定义。
框架使用实用程序助手类。例如， AutoJsonUtility.java是一个
加载给定设备 JSON 配置文件并在运行时更新框架配置的实用程序类。
应用助手实现模块是 Spectatio 框架的核心。它包含应用程序助手接口中定义的助手函数的实现，这是在汽车设备上测试应用程序所必需的。每个应用程序都有自己的实现，例如SettingHelperImpl和DialHelperImpl ，供 Automotive 测试用于测试应用程序。有关更多信息和实现列表，请参阅 AOSP 上的应用程序助手实现函数。
Automotive Tests使用应用程序助手实现函数来测试与应用程序相关的各种操作。使用HelperAccessor类来访问应用程序助手实现函数。
以下代码显示了示例汽车测试的设置、清理和执行。
@RunWith(AndroidJUnit4.class)
public class AutoApplicationTest {
static HelperAccessor<IAutoApplicationHelper> autoApplicationHelper =
new HelperAccessor<>(IAutoApplicationHelper.class);
public AutoApplicationTest() {
// constructor
// Initialize any attributes that are required for the test execution
}
@Before
public void beforeTest() {
// Initial setup before each test
// For example - open the application
autoApplicationHelper.open();
}
@After
public void afterTest() {
// Cleanup after each test.
// For example - exit the application
autoApplicationHelper.exit();
}
@Test
public void testApplicationFeature() {
// Test
// For example - Test if application is open
assertTrue("Application is not open.", autoApplicationHelper.isOpen());
}
}
定制
Spectatio 框架独立于设备 UI，因此可扩展以测试具有不同 UI 和硬件的设备。为了实现这种可扩展性，Spectatio 使用基于参考设备的默认设备配置。为了支持非默认设备配置，框架在运行时使用 JSON 配置文件来设置设备所需的 UI 更改。 JSON 配置文件支持TEXT 、 DESCRIPTION和RESOURCE_ID等 UI 元素以及path设置，并且必须仅包含有关 DUT 的 UI 更改的信息。其余的 UI 元素使用框架中提供的默认配置值。
默认设备配置

非默认设备配置
以下代码示例显示了 JSON 配置文件的示例，其中默认设置被 DUT 上的设置覆盖。在这个例子中：
- Internet 设置在参考设备上命名为
Network & internet，在 DUT 上命名为Connectivity。 - 日期和时间设置位于参考设备的设置
Settings > Date and time日期和时间，以及 DUT 的Settings > System > Date and time。
# JSON configuration file for Reference Device
{
....
"NETWORK_AND_INTERNET_SETTINGS": {
"path": "Settings > Network & internet"
},
"DATE_AND_TIME_SETTINGS": {
"path": "Settings > Date and time"
},
....
}
# JSON configuration file for non-reference device
{
....
"NETWORK_AND_INTERNET_SETTINGS": {
"path": "Settings > Connectivity"
},
"DATE_AND_TIME_SETTINGS": {
"path": "Settings > System > Date and time"
},
....
}
当 JSON 配置文件准备好后，它会在运行时提供，如以下代码块所示。
# Push The JSON configuration file to the device
adb -s DEVICE-SERIAL push PATH-OF-JSON-FILE /data/local/tmp/jsonFile.json
在这些命令中：
- PATH-TO-JSON-FILE ：主机上 JSON 文件的路径。
- DEVICE-SERIAL ：DUT 的序列号。如果只有一个设备连接到主机，则不需要此参数。
构建和执行
Spectatio 框架是作为测试 APK 的一部分自动构建的。要构建测试 APK，AOSP 代码库必须驻留在本地工作站上。测试 APK 构建完成后，用户必须在设备上安装 APK 并执行测试。
以下代码示例显示了测试 APK 的构建、安装和执行。
# Build Test APK
make TEST-APK-NAME
# Install Test APK
adb -s DEVICE-SERIAL install -r PATH-FOR-BUILT-TEST-APK
# Execute Test with the JSON file
adb -s DEVICE-SERIAL shell am instrument -w -r -e debug false -e config-file-path /data/local/tmp/jsonFile.json -e class TEST-PACKAGE.TEST-CLASSNAME TEST-PACKAGE/androidx.test.runner.AndroidJUnitRunner
在这些命令中：
TEST-APK-NAME ：要测试的应用的名称。例如，将TEST-APK-NAME设置为
AndroidAutomotiveSettingsTests以测试Android.bp文件中指定的 Wi-Fi 设置。 APK 的名称可以在汽车测试的相应Android.bp文件中找到。DEVICE-SERIAL ：DUT 的序列号。如果只有一个设备连接到主机，则不需要此参数。
config-file-path：可选参数，仅用于提供JSON 配置文件中指定的非默认设备 UI 配置。如果未提供，框架将使用默认值来执行测试。PATH-FOR-BUILT-TEST-APK ：执行
make命令时构建测试 APK 的路径。TEST-PACKAGE ：测试包的名称。
TEST-CLASSNAME ：测试类的名称。例如，对于Wifi Settings测试，测试包为
android.platform.tests，测试类名称为WifiSettingTest。
