有没有一种方法只运行一组特定的测试，在Android摇篮的项目？ [英] Is there a way to only run a specific set of tests in an Android Gradle project?

问题描述

我有一个Android /摇篮工程。每当我想运行测试，我运行：

I have an Android/Gradle project. Whenever I want to run tests, I run:

./gradlew connectedInstrumentTest

它运行在我的项目的测试文件夹，我的所有测试。

which runs all my tests under the test folder of my project.

我的测试文件夹中有多个自动化测试以及非自动化的测试。我最感兴趣的是不慢的自动化测试运行速度快的非自动化的测试。

My test folder has several automation tests as well as non-automation tests. I'm mostly interested in running the fast non-automation tests without the slow automation tests.

有没有办法只运行一组特定的测试，例如从一个特定的类或任何类似？我基本上问任何分割，这样我就可以选择只运行一些测试时，我想。

Is there a way to run just a specific set of tests, such as from one specific class or anything similar? I'm basically asking about any kind of separation so that I can choose to run just a few tests when I want to.

创建了一个示例项目这里。

修改 local.properties 来指向您的Andr​​oid SDK。

Edit local.properties to point at your Android SDK.

接下来，启动仿真器或手机连接到您的计算机。然后，你可以使用运行测试 ./ gradlew connectedInstrumentTest --info 。这将运行所有测试。

Next, start up an emulator or connect a phone to your computer. Then you can run tests using ./gradlew connectedInstrumentTest --info. This runs all tests.

什么我无法弄清楚是如何只运行测试，比方说，有一类，而不是所有的测试。

What I am unable to figure out is how to only run tests in, say, one class and not all tests.

推荐答案

由于Android的摇篮插件1.3.0

从版本开始1.3.0可以（终于！）指定了Android摇篮插件必须通过对参数的 InstrumentationTestRunner 。

Starting from version 1.3.0 you can (finally!) specify the arguments the Android Gradle Plugin have to pass to the InstrumentationTestRunner.

例如，如果你想运行仅标注了 @SmallTest 测试而忽略其他：

For example, if you want to run only the tests annotated with @SmallTest and ignore the others:

android {
  //....
  defaultConfig {
  //....
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    testInstrumentationRunnerArgument "size", "small"
  }
}

旧的解决方法 此前插件1.3.0是不可能做到这一点，但我已经找到了一点workaound。基本上，我已经标注了 @SmallTest 标注的快速测试和使用的 InstrumentationTestRunner 我是一个自定义子类能够运行只是他们，而不是整个套件。

Old workaround Prior to plugin 1.3.0 is not possible to do that but I've found a little workaound. Basically I've annotated with the @SmallTest annotation the fast tests and using a custom subclass of the InstrumentationTestRunner I'm able to run just them and not the whole suite.

您可以发现，例如：code在这个主旨。
