Running android unit tests from the command line?
提问by folone
I'm trying to run unit tests on the android platform in accordance with tutorial. Say, for example, I want to run tests for Email application. I open /apps/Email/tests/AndroidManifest.xmlfile, look for the <manifest>element, and look at the packageattribute, which is com.android.email.tests, and in the <instrumentation>element I look at the android:nameattribute, which is android.test.InstrumentationTestRunner. Now I open the console, and run
我正在尝试按照教程在 android 平台上运行单元测试。比如说，我想为电子邮件应用程序运行测试。我打开/apps/Email/tests/AndroidManifest.xml文件，查找<manifest>元素，然后查看package属性，即com.android.email.tests，并在<instrumentation>元素中查看android:name属性，即android.test.InstrumentationTestRunner。现在我打开控制台，然后运行
$ . build/envsetup.sh
$ lunch 1
$ adb shell am instrument -w com.android.email.tests/android.test.InstrumentationTestRunner
But that fails:
但这失败了：
INSTRUMENTATION_STATUS: id=ActivityManagerService
android.util.AndroidException: INSTRUMENTATION_FAILED: com.android.email.tests/android.test.InstrumentationTestRunner
INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{com.android.email.tests/android.test.InstrumentationTestRunner}
So.. What am I doing wrong?
所以..我做错了什么？

Please run python development/testrunner/runtest.py email
请运行 python development/testrunner/runtest.py email
and then you will see it works :).
然后你会看到它有效:)。
Basically you do not have com.android.email.tests package installed.
基本上你没有安装 com.android.email.tests 包。
You can see what is available for instrumentation
您可以查看可用于检测的内容
pm list instrumentation
And you should see
你应该看到
instrumentation:com.android.email.tests/android.test.InstrumentationTestRunner (target=com.android.email)
仪器：com.android.email.tests/android.test.InstrumentationTestRunner (target=com.android.email)
And when doing
当做
pm list packages
package:com.android.email
package:com.android.email.tests
包：com.android.email
包：com.android.email.tests

You may need to setup a test project with the android create test-projectcommand first. Check this page on the Android Dev site: Testing In Other IDE'sfor more info. I've used this method to enable command line testing with ant.
您可能需要先使用该android create test-project命令设置一个测试项目。查看 Android 开发站点上的此页面：在其他 IDE 中测试以获取更多信息。我已经使用这种方法来启用 ant 的命令行测试。

What I actually forgot to do was building and installing that test packages onto my device/emulator. Discovered that after doing:
我实际上忘记做的是在我的设备/模拟器上构建和安装该测试包。做了之后发现：
$ adb shell
# cd data/packages
# ls
And no com.android.email.testspackage there.
com.android.email.tests那里没有包裹。

My issue was this tag:
我的问题是这个标签：
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:label="Tests for app.under.test.package"
android:targetPackage="app.under.test.package" />
Firstly I had the android:nameattribute wrong then the target package wrong (above is the correct solution)
首先我的android:name属性错误然后目标包错误（以上是正确的解决方案）

Test Package Not Installed on the Emulator
模拟器上未安装测试包
I had the exact same issue and realized that the test package hadn't been installed on the emulator, which is what @marekdef is saying.
我遇到了完全相同的问题，并意识到模拟器上尚未安装测试包，这就是@marekdef 所说的。
Instead of using the command found in the generated test file, I used the following:
我没有使用生成的测试文件中的命令，而是使用了以下命令：
ant debug install test
*I had my test project in <project_home>/testsso the following command is what I ended up using from my project homedirectory:
*我有我的测试项目，<project_home>/tests所以以下命令是我最终从我的项目主目录使用的命令：
(cd tests && ant debug install test;)
Hope that helps.
希望有帮助。

I have this run_all_test.shscript to run all unit and instrumented test:
我有这个run_all_test.sh脚本来运行所有单元和仪器测试：
#!/bin/bash
./gradlew --no-daemon clean test connectedCheck --stacktrace;
if [ $? -eq 0 ]
then
echo "tests are successful"
else
echo "tests FAILED"
exit 1
fi
Explanation:
解释：
test -> execute all unit test
connectedCheck -> execute all instrumented test
测试 -> 执行所有单元测试
connectedCheck -> 执行所有插桩测试
You can start from here to customize it based on your needs following the documentation here: https://developer.android.com/studio/test/command-line
您可以从这里开始根据您的需要按照此处的文档进行自定义：https: //developer.android.com/studio/test/command-line

I received the "Unable to find instrumentation info" error under this condition: I defined my test project with a src package name that was the same as that of the project-under-test. For example, the source for both projects was in package com.mycompany.android. This parallel-src-package setup worked fine in Eclipse, but on the emulator it very much appeared that the test apk was overwriting the app apk.
在这种情况下，我收到“无法找到检测信息”错误：我使用与被测项目相同的 src 包名称定义了我的测试项目。例如，两个项目的源代码都在包 com.mycompany.android 中。这个 parallel-src-package 设置在 Eclipse 中运行良好，但在模拟器上很明显测试 apk 覆盖了应用 apk。
Fix: I changed the src packge of the test project to test.mycompany.android.
修复：我将测试项目的src包改为test.mycompany.android。
Note that, in either case, the Android manifest for the test project defines:
请注意，无论哪种情况，测试项目的 Android 清单都定义了：
< manifest package="pkg-of-project-under-test" ...>
< manifest package="pkg-of-project-under-test" ...>
and
和
< instrumentation android:targetPackage="pkg-of-project-under-test" ...>
<检测android:targetPackage="pkg-of-project-under-test" ...>
