.subscribeOn變換上面function的執行序(只能改一次)(往下遞延)

https://projectlombok.org/features/all

使用CountDownLatch來做等待的動作
執行CountDownLatch.await()會讓執行序停止

1.gradle新增clearData的task

當用到enbase64 class做單元測試時，要使用androidTest

1.gradle 新增依賴

testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.0.2'
androidTestImplementation 'androidx.test:rules:1.2.0'

2.取得context

1.gradle加入junit依賴

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

android {
    defaultConfig {
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
}

2.單元測試代碼

目的：將物件統合在一個容器內做管理

1.gradle依賴

//dagger
implementation 'com.google.dagger:dagger:2.24'
annotationProcessor 'com.google.dagger:dagger-compiler:2.24'
implementation 'com.google.dagger:dagger-android:2.24'
implementation 'com.google.dagger:dagger-android-support:2.24'
annotationProcessor 'com.google.dagger:dagger-android-processor:2.24'

2.將component注入在application

gradle新增依賴

implementation "io.reactivex.rxjava2:rxjava:2.1.7"
implementation "io.reactivex.rxjava2:rxandroid:2.0.1"
