Executar testes é uma etapa importante do processo de desenvolvimento para garantir níveis de qualidade aceitáveis pelos usuários de sua aplicação. No entanto com o aumento do número de funcionalidades e as frequentes ondas de novos devices esta tarefa tem se tornado cada vez mais árdua, além de extremamente repetitiva, tediosa e sujeita à erros. No mundo Android algumas ferramentas podem lhe auxiliar a automatizar seu processo de testes, o Espresso e o UIAutomator são duas delas que recentemente foram adicionadas ao Android Testing Framework. Nesta palestra trataremos de como utilizar estes frameworks em seu projeto Android para automatizar e simular a interação do usuário com sua app e validar funcionalidades de sua aplicação no processo tornando o seu dia mais legal e produtivo.

Instrumentation
10
• Android Components Context Access;
• Components Lifecycle Control;
• Component Loading Control;
• System Events (e.g.: Broadcasts)
• InstrumentationTestRunner
• AndroidJUnitRunner
• GoogleInstrumentationTestRunner

10. Intel Software and Services Group
Espresso
11
• Simplifies the UI Test
Process within your App
• Methods for:
• View matching
• Checks
• UI Events

11. Intel Software and Services Group 12
Espresso - Configuration
dependencies {
androidTestCompile 'com.android.support.test:runner:0.3'
androidTestCompile 'com.android.support.test:rules:0.3'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2'
}
build.gradle
Desabilitar nas opções do desenvolvedor (no device):
• Window Animation Scale
• Transition Animation Scale
• Animator Duration Scale

Espresso – Vilibra Case
• Virtual Librarian
• Help to remember the books I
lend
• How to automate the lend
details view?
• Class:
TestViewLendedBookDetailFlow

13. Intel Software and Services Group 14
Check the code!
Instrumented Test Package:
vilibra/app/src/main/androidTest/java/ecarrara/eng/vilibra/
Test Class:
TestViewLendedBookDetailFlow.java

14. Intel Software and Services Group
UI Automator
24
• Cross App Testing
• Instrumentation Based
• Interact with visible
elements using
descriptors (like text).

15. Intel Software and Services Group 25
UIAutomator - Configuração
build.gradle
É necessário inspecionar os componentes visuais das apps alvo para garantir que o
UIAutomator consiga localizá-los.
Isso significa ter labels de texto visíveis, a propriedade android:contentDescription
preenchida, ou ainda a propriedade android:hint (para EditTexts)
dependencies {
androidTestCompile 'com.android.support.test:runner:0.3'
androidTestCompile 'com.android.support.test:rules:0.3'
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-
v18:2.1.1'
}

1. Extend the InstrumentationTestCase class.
2. Get an instance of UIDevice.
3. Use the method UIDevice.findObject() to get UIObjects and
execute Actions.
4. Use asserts to check the results.
