从gradle运行单个Android（单元）测试，而不加载其他项目依赖项

Question

我正在使用Jake Wharton的精彩插件进行Android单元测试。 我努力让这些单元测试运行的目的是为了速度（TDD快速反馈和所有）。

我已经设法正确配置它并运行一些示例测试，如下所示：

./gradlew test

每当我运行测试时，我会注意到以下输出：

Relying on packaging to define the extension of the main artifact has been deprecated and is scheduled to be removed in Gradle 2.0
The Test.testReportDir property has been deprecated and is scheduled to be removed in Gradle 2.0. Please use the Test.getReports().getHtml().getDestination() property instead.
The TaskContainer.add() method has been deprecated and is scheduled to be removed in Gradle 2.0. Please use the create() method instead.

Gradle似乎正在为我的项目加载所有依赖项。

我的样本测试如下：

package com.mycompany.mysampleapp;

import org.junit.Test;

import static org.fest.assertions.api.Assertions.assertThat;

public class AdditionOperationsTest {
  @Test public void testModulus() {
    assertThat(1).isEqualTo(1);
  }
}

这个测试实际上应该只需要几分之一秒才能运行。 我的理解是，所有预先加载项目依赖项的行为都会让它陷入困境。

在美好的日子里，我会确保我在CLASSPATH中拥有我需要的东西并运行如下：

javac src/test/java/main/java/com/micromobs/pkk/AdditionOperationsTest.java
java org.junit.runner.JUnitCore com.micromobs.pkk.AdditionOperationsTest

考虑到这是一个带有gradle的Android项目，我假设我必须做一些不同的事情，比如在gradle构建文件中创建特定任务，其中只包括我的示例项目的测试文件，然后运行gradle命令。 / gradlew taskName？

问题：是否可以单独在我的项目（com.mycompany.mysampleapp）的上下文中运行单个测试“AdditionOperationsTest”，以便它不会加载外部项目依赖项

这是我的配置文件目前的样子：

# settings.gradle
include ':libraries:gradle-android-test-plugin'
include ':libraries:facebook', ':mysampleapp'

# build.gradle
...
apply plugin: 'android-test'

dependencies {
    testCompile 'junit:junit:4.10'
    testCompile 'org.robolectric:robolectric:2.1.+'
    testCompile 'com.squareup:fest-android:1.0.+'
}

# location of my test files:
androidproj/mysampleapp/src/test/java/main/com/mycompany/mysampleapp/AdditionOperationsTest.java

Answer 1

您应该可以使用-a 命令行选项 （不重建项目依赖项）来执行此操作。 执行gradle -a test应该导致libraries:facebook和mysampleapp项目没有被重建。

编辑：如下所述，您可以使用Gradle守护程序显着提高Gradle构建的性能。
