Android-代码结构图
由上图可知，项目分层1个app目录，4个测试目录
app目录分为：
4个测试目录分别是：
androidTest: UI层测试
androidTestMock: UI层测试，mock数据支持
test:业务层单元测试
mock:业务层单元测试,mock数据支持
首先，我们来看下build.gradle(Module:app)文件
apply plugin: 'com.android.application'
android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
defaultConfig {
applicationId "com.example.android.architecture.blueprints.todomvp"
minSdkVersion rootProject.ext.minSdkVersion
targetSdkVersion rootProject.ext.targetSdkVersion
versionCode 1
versionName "1.0"
testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
}
buildTypes {
debug {
minifyEnabled true
// Uses new built-in shrinker http://tools.android.com/tech-docs/new-build-system/built-in-shrinker
useProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.pro'
}
release {
minifyEnabled true
useProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.pro'
}
}
// If you need to add more flavors, consider using flavor dimensions.
productFlavors {
mock {
applicationIdSuffix = ".mock"
}
prod {
}
}
// Remove mockRelease as it's not needed.
android.variantFilter { variant ->
if(variant.buildType.name.equals('release')
&& variant.getFlavors().get(0).name.equals('mock')) {
variant.setIgnore(true);
}
}
// Always show the result of every unit test, even if it passes.
testOptions.unitTests.all {
testLogging {
events 'passed', 'skipped', 'failed', 'standardOut', 'standardError'
}
}
}
/*
Dependency versions are defined in the top level build.gradle file. This helps keeping track of
all versions in a single place. This improves readability and helps managing project complexity.
*/
dependencies {
// App's dependencies, including test
compile "com.android.support:appcompat-v7:$rootProject.supportLibraryVersion"
compile "com.android.support:cardview-v7:$rootProject.supportLibraryVersion"
compile "com.android.support:design:$rootProject.supportLibraryVersion"
compile "com.android.support:recyclerview-v7:$rootProject.supportLibraryVersion"
compile "com.android.support:support-v4:$rootProject.supportLibraryVersion"
compile "com.android.support.test.espresso:espresso-idling-resource:$rootProject.espressoVersion"
compile "com.google.guava:guava:$rootProject.guavaVersion"
// Dependencies for local unit tests
testCompile "junit:junit:$rootProject.ext.junitVersion"
testCompile "org.mockito:mockito-all:$rootProject.ext.mockitoVersion"
testCompile "org.hamcrest:hamcrest-all:$rootProject.ext.hamcrestVersion"
// Android Testing Support Library's runner and rules
androidTestCompile "com.android.support.test:runner:$rootProject.ext.runnerVersion"
androidTestCompile "com.android.support.test:rules:$rootProject.ext.runnerVersion"
// Dependencies for Android unit tests
androidTestCompile "junit:junit:$rootProject.ext.junitVersion"
androidTestCompile "org.mockito:mockito-core:$rootProject.ext.mockitoVersion"
androidTestCompile 'com.google.dexmaker:dexmaker:1.2'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.2'
// Espresso UI Testing
androidTestCompile "com.android.support.test.espresso:espresso-core:$rootProject.espressoVersion"
androidTestCompile ("com.android.support.test.espresso:espresso-contrib:$rootProject.espressoVersion")
androidTestCompile "com.android.support.test.espresso:espresso-intents:$rootProject.espressoVersion"
// Resolve conflicts between main and test APK:
androidTestCompile "com.android.support:support-annotations:$rootProject.supportLibraryVersion"
androidTestCompile "com.android.support:support-v4:$rootProject.supportLibraryVersion"
androidTestCompile "com.android.support:recyclerview-v7:$rootProject.supportLibraryVersion"
}
在defaultConfig中
testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
是用来
在buildTypes中，relase模式下启用了混淆，我们来分析下下面两行代码：
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.pro'
proguard-rules.pro 文件代码：
# Some methods are only called from tests, so make sure the shrinker keeps them.
-keep class com.example.android.architecture.blueprints.** { *; }
-keep class android.support.v4.widget.DrawerLayout { *; }
-keep class android.support.test.espresso.IdlingResource { *; }
-keep class com.google.common.base.Preconditions { *; }
# For Guava:
-dontwarn javax.annotation.**
-dontwarn javax.inject.**
-dontwarn sun.misc.Unsafe
# Proguard rules that are applied to your test apk/code.
-ignorewarnings
-keepattributes *Annotation*
-dontnote junit.framework.**
-dontnote junit.runner.**
-dontwarn android.test.**
-dontwarn android.support.test.**
-dontwarn org.junit.**
-dontwarn org.hamcrest.**
-dontwarn com.squareup.javawriter.JavaWriter
# Uncomment this if you use Mockito
-dontwarn org.mockito.**
proguard-rules.pro 文件代码：
# Proguard rules that are applied to your test apk/code.
-ignorewarnings
-keepattributes *Annotation*
-dontnote junit.framework.**
-dontnote junit.runner.**
-dontwarn android.test.**
-dontwarn android.support.test.**
-dontwarn org.junit.**
-dontwarn org.hamcrest.**
-dontwarn com.squareup.javawriter.JavaWriter
# Uncomment this if you use Mockito
-dontwarn org.mockito.**
在上面的build文件中，发现有比较多的
rootProject.ext.compileSdkVersion
rootProject.ext.buildToolsVersion、
rootProject.supportLibraryVersion
rootProject.espressoVersion
是因为？
我们来看下build.gradle(Project:todoapp)文件：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
// Define versions in a single place
ext {
// Sdk and tools
minSdkVersion = 10
targetSdkVersion = 22
compileSdkVersion = 23
buildToolsVersion = '23.0.2'
// App dependencies
supportLibraryVersion = '23.4.0'
guavaVersion = '18.0'
junitVersion = '4.12'
mockitoVersion = '1.10.19'
powerMockito = '1.6.2'
hamcrestVersion = '1.3'
runnerVersion = '0.4.1'
rulesVersion = '0.4.1'
espressoVersion = '2.2.1'
}
下面这段代码：
task clean(type: Delete) { delete rootProject.buildDir}
前面铺垫了这么久，终于到代码时间了
