Android，Gradle。如何构建应用程序并从测试应用程序运行测试 [英] Android, Gradle. How to build application and run tests from test application
问题描述
我有android项目和android测试项目，它位于文件夹测试下。这些项目的结构是类似于eclipse的
+ - src
| - res
| - libs
| - 测试
| .....
我使用gradle。我想要的只是构建应用程序，运行单元测试并获取它们的报告。但我不明白如何做对。我在根文件夹中创建了build.gradle文件
buildscript {
repositories {
mavenCentral（）
}
依赖关系{
classpath'com.android.tools.build:gradle:0.5.+'
}
}
apply插件：'android'
android {
compileSdkVersion 18
buildToolsVersion18.1.1
defaultConfig {
minSdkVersion 8
targetSdkVersion 18
testPackageNameua.cooperok.stringcalc.tests
testInstrumentationRunnerandroid.test.InstrumentationTestRunner
}
sourceSets {
main {
manifest.srcFile' AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['asset s']
}
unitTest {
java.srcDir文件（'tests / src'）
resources.srcDir文件（'tests / res'）
}
}
配置{
unitTestCompile.extendsFrom运行时
unitTestRuntime.extendsFrom unitTestCompile
}
依赖关系{
unitTestCompile文件（$ project.buildDir / classes / release）
}
任务unitTest（类型：Test）{
description =运行单元测试...
testClassesDir = android.sourceSets.unitTest.output.classesDir
classpath = android.sourceSets.unitTest.runtimeClasspath
}
build.dependsOn unitTest
}
但是当我运行 gradle build 时，出现错误
无法在源集单元测试中找到属性'输出'。
另外，据我所知，为了得到我需要的报告应用插件android-rep orting，但是当我这样做时，我得到了错误
无法添加名为'android'的扩展名，因为有一个扩展名已经注册了该名称。
我应该这样做，还是必须在我的测试应用程序项目中创建新的gradle.build文件？
UPDATE
我修正了输出错误，并使gradle build成功，但我不明白是什么原因。我故意失败了我的测试，但gradle构建仍然成功。
我所做的：
1.我将任务unitTest从android部分移至root，之后，我的测试项目开始编译，但有一个错误'packackage android.test未找到'
2.为了解决我添加到android源码的classpath路径的错误，所以在gradle build成功之后，我不明白为什么它总是成功，即使在测试失败时也是如此。
我仍然不明白如何从测试中获取报告。
这是我的新build.gradle文件
buildscript {
repositories {
mavenCentral（）
}
依赖关系{
classpath'com.android.tools.build:gradle:0.6+'
}
}
apply插件：'android'
android {
compileSdkVersion 18
buildToolsVersion18.1.1
defaultConfig {
minSdkVersion 8
targetSdkVersion 18
testPackageNameua.cooperok.stringcalc.tests
testInstrumentationRunnerandroid.test.InstrumentationTestRunner
}
sourceSets {
main {
manifest .srcFile文件（'AndroidManifest.xml'）
java.srcDirs = ['src']
resources.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
}
依赖关系{
编译fileTree（dir：'libs'，include：'* .jar'）
$ b $ sourceSets {
unitTest {
java.srcDirs = ['tests / src']
resources.srcDirs = [' tests / src']
}
}
配置{
unitTestCompile.extendsFrom运行时
unitTestRuntime.extendsFrom unitTestCompile
}
依赖关系{
unitTestCompile文件（$ project.buildDir / classes / release）
unitTestCompile'junit：junit：4.11'
编译fileTree（dir：'libs'，包括：'* .jar'）
}
任务unitTest（类型：Test， dependsOn：assemble）{
description =运行单元测试
testClassesDir = sourceSets.unitTest.output.classesDir
classpath = files（$ System.env.ANDROID_HOME / sources / android-18 ）
// actualy我没有得到任何报告
getReports（）。getJunitXml（）。setOutputPerTestCase（true）
}
build.dependsOn unitTest
我找到了解决方案。我很少被几个主题所厌倦，并认为我需要为单元测试创建单独的任务。实际上它很简单。
我没有改变我的项目结构，只是build.gradle文件。为了构建应用程序，我运行
gradle clean connectedCheck build
$ b $ connectedCheck从我的测试项目运行单元测试，如果某些测试失败 - gradle build也会失败

I have android project and android test project inside it, located under folder tests. Structure of these project is eclipse like
+-src
| - res
| - libs
| - tests
|.....
I use gradle. All i want is to build app, run unit tests and get reports of them. But i don't understand how to do it right. I'm created build.gradle file in root folder
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android'
android {
compileSdkVersion 18
buildToolsVersion "18.1.1"
defaultConfig {
minSdkVersion 8
targetSdkVersion 18
testPackageName "ua.cooperok.stringcalc.tests"
testInstrumentationRunner "android.test.InstrumentationTestRunner"
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
unitTest {
java.srcDir file('tests/src')
resources.srcDir file('tests/res')
}
}
configurations {
unitTestCompile.extendsFrom runtime
unitTestRuntime.extendsFrom unitTestCompile
}
dependencies {
unitTestCompile files("$project.buildDir/classes/release")
}
task unitTest(type:Test){
description = "Run unit tests..."
testClassesDir = android.sourceSets.unitTest.output.classesDir
classpath = android.sourceSets.unitTest.runtimeClasspath
}
build.dependsOn unitTest
}
But when i run gradle build i got error
Could not find property 'output' on source set unit test.
Also, as i understand, to get reports i need to apply plugin "android-reporting", but when i do this i got error
Cannot add extension with name 'android', as there is an extension already registered with that name.
Should i do it like this, or i must create new gradle.build file in my test application project?
UPDATE
I fixed error with output, and made gradle build successful, but I don't understand what's goind on. I purposely failed my test, but gradle build is still successful.
What I've done:
1. I moved task unitTest from android section to root, after that, my test project began to compile, but there is an error 'packackage android.test not found'
2. To fix that error I added to classpath path to android sources, so after that gradle build was successful, but realy I don't understand why it's always successful even when test fails
And still I don't understand how to get reports from test
This is my new build.gradle file
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.6+'
}
}
apply plugin: 'android'
android {
compileSdkVersion 18
buildToolsVersion "18.1.1"
defaultConfig {
minSdkVersion 8
targetSdkVersion 18
testPackageName "ua.cooperok.stringcalc.tests"
testInstrumentationRunner "android.test.InstrumentationTestRunner"
}
sourceSets {
main {
manifest.srcFile file('AndroidManifest.xml')
java.srcDirs = ['src']
resources.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
}
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
}
sourceSets {
unitTest {
java.srcDirs = ['tests/src']
resources.srcDirs = ['tests/src']
}
}
configurations {
unitTestCompile.extendsFrom runtime
unitTestRuntime.extendsFrom unitTestCompile
}
dependencies {
unitTestCompile files("$project.buildDir/classes/release")
unitTestCompile 'junit:junit:4.11'
compile fileTree(dir: 'libs', include: '*.jar')
}
task unitTest(type:Test, dependsOn: assemble) {
description = "run unit tests"
testClassesDir = sourceSets.unitTest.output.classesDir
classpath = files("$System.env.ANDROID_HOME/sources/android-18")
//actualy I didn't get any report
getReports().getJunitXml().setOutputPerTestCase(true)
}
build.dependsOn unitTest
I found solution. I was dissapointed by few topics, and thought that i need to create separate task for unit tests. In fact it was prety easy.
I didn't change my project structure, just build.gradle file. To build application i run
gradle clean connectedCheck build
connectedCheck runs unit tests from my test project and if some test fails - gradle build will fails too
Here final version of it
buildscript {
repositories {
mavenCentral()

dependencies {
classpath 'com.android.tools.build:gradle:0.6+'
}

android {

}
sourceSets {
main {
manifest.srcFile file('AndroidManifest.xml')
java.srcDirs = ['src']
resources.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
instrumentTest {
java.srcDirs = ['tests/src']
manifest.srcFile file('tests/AndroidManifest.xml')
resources.srcDirs = ['tests/src']
res.srcDirs = ['tests/res']
assets.srcDirs = ['tests/assets']
}
}
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
//Signing apk
if(project.hasProperty("signingPropertiesPath")) {
File propsFile = new File(System.getenv('HOME') + "/" + project.property("signingPropertiesPath"))
if(propsFile.exists()) {

props.load(new FileInputStream(propsFile))
//loading keystore properties
signingConfigs {
release {
storeFile file(propsFile.getParent() + "/" + props['keystore'])
storePassword props['keystore.password']
keyAlias props['keyAlias']

}
}
