This library is a collection of Kotlin extension and infix functions made to increase
the readability and decrease the boilerplate of Espresso and UIAutomator matchers
and actions.
It is inteded to work well with RobotPattern, as the naming convention of the functions assume to have some sort of semantical context on the call site.
This is a Work In Progress, and contributions are highly welcomed. For the future plans of library development, please check the Wiki.
Simple test example:
@Test
fun shouldLoginUser_whenStartingTheAppForTheFirstTime() {
withLoginRobot {
loginDemoUser()
} andThen {
acceptThePermissions
} andThenVerifyThat {
userIsLoggedIn()
}
}In order to login the user properly, we have to find a login button, and username and password fields.
Unified Espresso/UIAutomator syntax - KTX
class MainActivityTest {
@Test
fun shouldLoginDemoUser(){
typeText("dummyUsername") into text(R.id.activityLoginEditTextUsername)
typeText("dummyPassword") into text(R.id.activityLoginEditTextPassword)
click on button(R.id.activityLoginBtnLogin)
MainActivity::class verifyThat { itIsDisplayed() }
}
}In the old fashion way, we'd do something like this:
Espresso syntax
class MainActivityTest {
@Test
fun shouldLoginDemoUser(){
onView(withId(R.id.activityLoginEditTextUsername)).perform(typeText("dummyUsername"))
onView(withId(R.id.activityLoginEditTextPassword)).perform(typeText("dummyPassword"))
onView(withId(R.id.activityLoginBtnLogin)).perform(click())
Intents.intended(IntentMatchers.hasComponent(MainActivity::class.java.name))
}
}UIAutomator syntax
class MainActivityTest {
@Test
fun shouldLoginDemoUser(){
val instrumentation = InstrumentationRegistry.getInstrumentation()
val uiDevice = UiDevice.getInstance(instrumentation)
val appContext = InstrumentationRegistry.getInstrumentation().targetContext
val usernameSelector = UiSelector().resourceId(appContext.resources.getResourceName(
R.id.activityLoginEditTextUsername
)
)
val usernameTextField = uiDevice.findObject(usernameSelector)
usernameTextField.text = "dummyUsername"
val passwordSelector = UiSelector().resourceId(appContext.resources.getResourceName(
R.id.activityLoginEditTextPassword
)
)
val passwordTextField = uiDevice.findObject(passwordSelector)
passwordTextField.text = "dummyPassword"
val loginButtonSelector = UiSelector().resourceId(appContext.resources.getResourceName(
R.id.activityLoginBtnLogin
)
)
val loginButton = uiDevice.findObject(loginButtonSelector)
loginButton.click()
Intents.intended(IntentMatchers.hasComponent(MainActivity::class.java.name))
}
}In the build.gradle file of your app module, put this line into the dependencies:
androidTestImplementation 'de.codecentric:androidtestktx:0.9.0'
Make sure that in the project level build.gradle file, you're using the JCenter as repository source:
allprojects {
repositories {
...
jcenter()
}
