Instrumentation
11
• 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
12
• Simplifies the UI Test
Process within your App
• Methods for:
• View matching
• Checks
• UI Events

11. Intel Software and Services Group 13
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:

UIAutomator
26
• Cross App Testing
• Instrumentation Based
• Interact with visible
elements using
descriptors (like text).

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'
}

UIAutomator – Trecho Minimo de Código
@Test public void myAwesomeTest() throws UiObjectNotFoundException {
// encontre o objeto com as caracteristicas e faça um click
mUiDevice.findObject(
new UiSelector()
.className("class-name")
.resourceId("resource-id")
.text("view-text"))
.click();
