AndroidComposeUiTestEnvironment

android

Artifact: androidx.compose.ui:ui-test

View Source

@ExperimentalTestApi
inline fun <A : ComponentActivity> AndroidComposeUiTestEnvironment(
    effectContext: CoroutineContext = EmptyCoroutineContext,
    runTestContext: CoroutineContext = EmptyCoroutineContext,
    testTimeout: Duration = 60.seconds,
    crossinline activityProvider: () -> A?
): AndroidComposeUiTestEnvironment<A>

Creates an AndroidComposeUiTestEnvironment that retrieves the host Activity by delegating to the given activityProvider. Use this if you need to launch an Activity in a way that is not compatible with any of the existing runComposeUiTest, runAndroidComposeUiTest, or runEmptyComposeUiTest methods.

Valid use cases include, but are not limited to, creating your own JUnit test rule that implements AndroidComposeUiTest by delegating to AndroidComposeUiTestEnvironment.test. See AndroidComposeTestRule for a reference implementation.

The activityProvider is called every time activity is called, which in turn is called when setContent is called.

The most common implementation of an activityProvider retrieves the activity from a backing ActivityScenario (that the caller launches within the lambda passed to runTest), but one is not limited to this pattern.

Parameters
`<A : ComponentActivity>`	The Activity type to be interacted with, which typically (but not necessarily) is the activity that was launched and hosts the Compose content.
`effectContext: CoroutineContext = EmptyCoroutineContext`	The `CoroutineContext` used to run the composition. The context for `LaunchedEffect`s and `rememberCoroutineScope` will be derived from this context. If this context contains a `TestDispatcher` or `TestCoroutineScheduler` (in that order), it will be used for composition and the `MainTestClock`.
`runTestContext: CoroutineContext = EmptyCoroutineContext`	The `CoroutineContext` used to create the context to run the test. By default it will run using `kotlinx.coroutines.test.StandardTestDispatcher`. `runTestContext` and `effectContext` must not share `TestCoroutineScheduler`.
`testTimeout: Duration = 60.seconds`	The `Duration` within which the test is expected to complete, otherwise a platform specific timeout exception will be thrown.
`crossinline activityProvider: () -> A?`	A lambda that should return the current Activity instance of type `A`, if it is available. If it is not available, it should return `null`.

DeviceConfigurationOverride

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

Added in 1.7.0

@Composable
fun DeviceConfigurationOverride(
    override: DeviceConfigurationOverride,
    content: @Composable () -> Unit
): Unit

Applies DeviceConfigurationOverride to the content under test to apply some configuration override.

This can be useful to locally test behavior in isolation that depends on properties that are normally device-wide, such as font scale, screen size and layout direction.

import androidx.compose.ui.test.DeviceConfigurationOverride
import androidx.compose.ui.test.FontScale

DeviceConfigurationOverride(DeviceConfigurationOverride.FontScale(1.5f)) {
    MyScreen() // will be rendered with a larger than default font scale
}

import androidx.compose.ui.test.DeviceConfigurationOverride
import androidx.compose.ui.test.ForcedSize
import androidx.compose.ui.unit.DpSize
import androidx.compose.ui.unit.dp

DeviceConfigurationOverride(DeviceConfigurationOverride.ForcedSize(DpSize(1280.dp, 800.dp))) {
    MyScreen() // will be rendered in the space for 1280dp by 800dp without clipping
}

import androidx.compose.ui.test.DeviceConfigurationOverride
import androidx.compose.ui.test.LayoutDirection
import androidx.compose.ui.unit.LayoutDirection

DeviceConfigurationOverride(DeviceConfigurationOverride.LayoutDirection(LayoutDirection.Rtl)) {
    MyComponent() // will be rendered with a right-to-left layout direction
}

PlatformTextInputMethodTestOverride

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

Added in 1.6.0

Deprecated in 1.7.0

@ExperimentalTestApi
@Composable
fun PlatformTextInputMethodTestOverride(
    sessionHandler: PlatformTextInputSession,
    content: @Composable () -> Unit
): Unit

Installs a custom PlatformTextInputSession implementation to run when PlatformTextInputSession.startInputMethod is called by text editors inside content.

Parameters
`sessionHandler: PlatformTextInputSession`	The `PlatformTextInputSession` to use to handle input method requests. This object does not need to worry about synchronizing calls to `PlatformTextInputSession.startInputMethod` – this composable will handle the session management the same way as in production.
`content: @Composable () -> Unit`	The composable content for which to override the input method handler.

addGlobalAssertion

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

Added in 1.6.0

Deprecated in 1.9.0-beta03

@ExperimentalTestApi
fun addGlobalAssertion(
    name: String,
    assertion: (SemanticsNodeInteraction) -> Unit
): Unit

Adds a named assertion to the collection of assertions to be executed before test actions.

This API is intended to be invoked by assertion frameworks to register assertions that must hold on the entire application whenever it's fully loaded and ready to interact with. They will be invoked upon common actions such as performClick, and they always verify every element on the screen, not just the element the action is performed on.

This is particularly useful to automatically catch accessibility problems such as contrast ratio, minimum touch-target size, etc.

Parameters
`name: String`	An identifier for the assertion. It can subsequently be used to deactivate the assertion with `removeGlobalAssertion`.
`assertion: (SemanticsNodeInteraction) -> Unit`	A function to be executed.

    runTestContext: CoroutineContext = EmptyCoroutineContext,
    testTimeout: Duration = 60.seconds,
    noinline block: suspend AndroidComposeUiTest<A>.() -> Unit
): Unit

Variant of runComposeUiTest that allows you to specify which Activity should be launched. Be aware that if the Activity sets content during its launch, you cannot use setContent on the ComposeUiTest anymore as this would override the content and can lead to subtle bugs.

Parameters
`<A : ComponentActivity>`	The Activity type to be launched, which typically (but not necessarily) hosts the Compose content
`effectContext: CoroutineContext = EmptyCoroutineContext`	The `CoroutineContext` used to run the composition. The context for `LaunchedEffect`s and `rememberCoroutineScope` will be derived from this context. If this context contains a `TestDispatcher` or `TestCoroutineScheduler` (in that order), it will be used for composition and the `MainTestClock`.
`runTestContext: CoroutineContext = EmptyCoroutineContext`	The `CoroutineContext` used to create the context to run the test `block`. By default `block` will run using `kotlinx.coroutines.test.StandardTestDispatcher`. `runTestContext` and `effectContext` must not share `TestCoroutineScheduler`.
`testTimeout: Duration = 60.seconds`	The `Duration` within which the test is expected to complete, otherwise a platform specific timeout exception will be thrown.
`noinline block: suspend AndroidComposeUiTest<A>.() -> Unit`	The test function.

): Unit

Parameters
`<A : ComponentActivity>`	The Activity type to be launched, which typically (but not necessarily) hosts the Compose content
`activityClass: Class<A>`	The `Class` of the Activity type to be launched, corresponding to `A`.
`effectContext: CoroutineContext = EmptyCoroutineContext`	The `CoroutineContext` used to run the composition. The context for `LaunchedEffect`s and `rememberCoroutineScope` will be derived from this context. If this context contains a `TestDispatcher` or `TestCoroutineScheduler` (in that order), it will be used for composition and the `MainTestClock`.

If you need access to platform specific elements (such as the Activity on Android), use one of the platform specific variants of this method, e.g. runAndroidComposeUiTest on Android.

Implementations of this method will launch a Compose host (such as an Activity on Android) for you. If your test needs to launch its own host, use a platform specific variant that doesn't launch anything for you (if available), e.g. runEmptyComposeUiTest on Android. Always make sure that the Compose content is set during execution of the test lambda so the test framework is aware of the content. Whether you need to launch the host from within the test lambda as well depends on the platform.

Keeping a reference to the ComposeUiTest outside of this function is an error.

Parameters
`effectContext: CoroutineContext = EmptyCoroutineContext`	The `CoroutineContext` used to run the composition. The context for `LaunchedEffect`s and `rememberCoroutineScope` will be derived from this context. If this context contains a TestDispatcher or TestCoroutineScheduler (in that order), it will be used for composition and the `MainTestClock`.
`runTestContext: CoroutineContext = EmptyCoroutineContext`	The `CoroutineContext` used to create the context to run the test `block`. By default `block` will run using kotlinx.coroutines.test.StandardTestDispatcher. `runTestContext` and `effectContext` must not share TestCoroutineScheduler.
`testTimeout: Duration = 60.seconds`	The `Duration` within which the test is expected to complete, otherwise a platform specific timeout exception will be thrown.
`block: suspend ComposeUiTest.() -> Unit`	The test function.

runEmptyComposeUiTest

android

Artifact: androidx.compose.ui:ui-test

View Source

@ExperimentalTestApi
fun runEmptyComposeUiTest(block: ComposeUiTest.() -> Unit): Unit

Variant of runComposeUiTest that does not launch an Activity to host Compose content in and thus acts as an "empty shell". Use this if you need to have control over the timing and method of launching the Activity, for example when you want to launch it with a custom Intent, or if you have a complex test setup.

When using this method, calling ComposeUiTest.setContent will throw an IllegalStateException. Instead, you'll have to set the content in the Activity that you have launched yourself, either directly on the Activity or on an androidx.compose.ui.platform.AbstractComposeView. You will need to do this from within the test lambda, or the test framework will not be able to find the content.

animateMoveAlong

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

Added in 1.8.0

fun MouseInjectionScope.animateMoveAlong(
    curve: (timeMillis: Long) -> Offset,
    durationMillis: Long = DefaultMouseGestureDurationMillis
): Unit

Move the mouse along the given curve, sending a stream of move events to get an animated path of durationMillis milliseconds. The mouse will initially be moved to the start of the path, curve(0), if it is not already there. The positions defined by the curve are in the node's local coordinate system, where (0, 0) is the top left corner of the node.

Example of moving the mouse along a curve:

import androidx.compose.ui.geometry.Offset
import androidx.compose.ui.test.animateMoveAlong
import androidx.compose.ui.test.onNodeWithTag
import androidx.compose.ui.test.performMouseInput

composeTestRule.onNodeWithTag("myComponent").performMouseInput {
    // Hover over the node, making a full circle with a radius of 100px
    val r = 100f
    animateMoveAlong(
        curve = {
            val angle = 2 * PI * it / 1000
            center + Offset(r * cos(angle).toFloat(), r * sin(angle).toFloat())
        },
        durationMillis = 1000L,
    )
}

Parameters
`curve: (timeMillis: Long) -> Offset`	The function that defines the position of the mouse over time for this gesture, in the node's local coordinate system. The argument passed to the function is the time in milliseconds since the start of the animated move, and the return value is the location of the mouse at that point in time
`durationMillis: Long = DefaultMouseGestureDurationMillis`	The duration of the gesture. By default 300 milliseconds.

): Unit

Move the mouse from the current position by the given delta, sending a stream of move events to get an animated path of durationMillis milliseconds.

Parameters
`delta: Offset`	The position where to move the mouse to, relative to the current position of the mouse. For example, `delta = Offset(100.px, -100.px) will move the mouse 100 pixels to the right and 100 pixels upwards.
`durationMillis: Long = DefaultMouseGestureDurationMillis`	The duration of the gesture. By default 300 milliseconds.

animateMoveTo

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

fun MouseInjectionScope.animateMoveTo(
    position: Offset,
    durationMillis: Long = DefaultMouseGestureDurationMillis
): Unit

Move the mouse from the current position to the given position, sending a stream of move events to get an animated path of durationMillis milliseconds. Move the mouse to the desired start position if you want to start from a different position. The position is in the node's local coordinate system, where (0, 0) is the top left corner of the node.

Example of moving the mouse along a line:

import androidx.compose.ui.test.animateMoveTo
import androidx.compose.ui.test.onNodeWithTag
import androidx.compose.ui.test.performMouseInput

composeTestRule.onNodeWithTag("myComponent").performMouseInput {
    // Hover over the node, making an X shape
    moveTo(topLeft)
    animateMoveTo(bottomRight)
    // Note that an actual user wouldn't be able to instantly
    // move from the bottom right to the top right
    moveTo(topRight)
    animateMoveTo(bottomLeft)
}

Parameters
`position: Offset`	The position where to move the mouse to, in the node's local coordinate system
`durationMillis: Long = DefaultMouseGestureDurationMillis`	The duration of the gesture. By default 300 milliseconds.

Captures the underlying semantics node's surface into bitmap. This can be used to capture nodes in a normal composable, a dialog if API >=28 and in a Popup. Note that the mechanism used to capture the bitmap from a Popup is not the same as from a normal composable, since a PopUp is in a different window.

Throws
`kotlin.IllegalArgumentException`	if we attempt to capture a bitmap of a dialog before API 28.

down

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

fun GestureScope.down(position: Offset): Unit

Sends a down event for the default pointer at position on the associated node. The position is in the node's local coordinate system, where (0, 0) is the top left corner of the node. The default pointer has pointerId = 0.

If no pointers are down yet, this will start a new gesture. If a gesture is already in progress, this event is sent with at the same timestamp as the last event. If the default pointer is already down, an IllegalArgumentException will be thrown.

Parameters
`position: Offset`	The position of the down event, in the node's local coordinate system

down

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

fun GestureScope.down(pointerId: Int, position: Offset): Unit

Sends a down event for the pointer with the given pointerId at position on the associated node. The position is in the node's local coordinate system, where (0, 0) is the top left corner of the node.

If no pointers are down yet, this will start a new gesture. If a gesture is already in progress, this event is sent with at the same timestamp as the last event. If the given pointer is already down, an IllegalArgumentException will be thrown.

Subsequent events for this or other gestures can be spread out over both this and future invocations of performGesture. An entire gesture starts with a down event, followed by several down, move or up events, and ends with an up or a cancel event. Movement can be expressed with moveTo and moveBy to move a single pointer at a time, or movePointerTo and movePointerBy to move multiple pointers at a time. The movePointer[To|By] methods do not send the move event directly, use move to send the move event. Some other methods can send a move event as well. All events, regardless the method used, will always contain the current position of all pointers.

Down and up events are sent at the same time as the previous event, but will send an extra move event just before the down or up event if movePointerTo or movePointerBy has been called and no move event has been sent yet. This does not happen for cancel events, but the cancel event will contain the up to date position of all pointers. Move and cancel events will advance the event time by 16 milliseconds.

Because gestures don't have to be defined all in the same performGesture block, keep in mind that while the gesture is not complete, all code you execute in between blocks that progress the gesture, will be executed while imaginary fingers are actively touching the screen.

In the context of testing, it is not necessary to complete a gesture with an up or cancel event, if the test ends before it expects the finger to be lifted from the screen.

Parameters
`pointerId: Int`	The id of the pointer, can be any number not yet in use by another pointer
`position: Offset`	The position of the down event, in the node's local coordinate system

performGesture

Cmn

Artifact: androidx.compose.ui:ui-test

View Source

Added in 1.0.0

Deprecated in 1.1.0

fun SemanticsNodeInteraction.performGesture(block: GestureScope.() -> Unit): SemanticsNodeInteraction

Executes the (partial) gesture specified in the given block. The gesture doesn't need to be complete and can be resumed in a later invocation of performGesture. The event time is initialized to the current time of the MainTestClock.

Be aware that if you split a gesture over multiple invocations of performGesture, everything that happens in between will run as if the gesture is still ongoing (imagine a finger still touching the screen).

All events that are injected from the block are batched together and sent after block is complete. This method blocks while the events are injected. If an error occurs during execution of block or injection of the events, all (subsequent) events are dropped and the error is thrown here.

Due to the batching of events, all events in a block are sent together and no recomposition will take place in between events. Additionally all events will be generated before any of the events take effect. This means that the screen coordinates of all events are resolved before any of the events can cause the position of the node being injected into to change. This has certain advantages, for example, in the cases of nested scrolling or dragging an element around, it prevents the injection of events into a moving target since all events are enqueued before any of them has taken effect.

Example of performing a click:

import androidx.compose.ui.test.click
import androidx.compose.ui.test.onNodeWithTag
import androidx.compose.ui.test.performGesture

composeTestRule.onNodeWithTag("myComponent").performGesture { click() }

Parameters
`block: GestureScope.() -> Unit`	A lambda with `GestureScope` as receiver that describes the gesture by sending all touch events.

Returns
`SemanticsNodeInteraction`	The `SemanticsNodeInteraction` that is the receiver of this method

Added in 1.1.0

fun SemanticsNodeInteraction.performMultiModalInput(block: MultiModalInjectionScope.() -> Unit): SemanticsNodeInteraction

Executes the multi-modal gesture specified in the given block. The gesture doesn't need to be complete and can be resumed in a later invocation of one of the perform.*Input methods. The event time is initialized to the current time of the MainTestClock. If only a single modality is needed (e.g. touch, mouse, stylus, keyboard, etc), you should use the perform.*Input of that modality instead.

Functions for each modality can be called by invoking that modality's function, like touch to inject touch events. This allows you to inject events for each modality.

Be aware that if you split a gesture over multiple invocations of perform.*Input, everything that happens in between will run as if the gesture is still ongoing (imagine a finger still touching the screen).

Parameters
`block: MultiModalInjectionScope.() -> Unit`	A lambda with `MultiModalInjectionScope` as receiver that describes the gesture by sending all multi modal events.

Added in 1.1.0

fun SemanticsNodeInteraction.performScrollToNode(
    matcher: SemanticsMatcher
): SemanticsNodeInteraction

Scrolls a scrollable container to the content that matches the given matcher. If the content isn't yet visible, the scrollable container will be scrolled from the start till the end till it finds the content we're looking for. It is not defined where in the viewport the content will be on success of this function, but it will be either fully within the viewport if it is smaller than the viewport, or it will cover the whole viewport if it is larger than the viewport. If it doesn't find the content, the scrollable will be left at the end of the content and an AssertionError is thrown.

This action should be performed on a node that is a scrollable container, not on a node that is part of the content of that container. If the container is a lazy container, it must support the semantics actions ScrollToIndex, ScrollBy, and either HorizontalScrollAxisRange or VerticalScrollAxisRange, for example LazyColumn and LazyRow. If the container is not lazy, it must support the semantics action ScrollBy, for example, Row or Column.

Throws an AssertionError if the scrollable node doesn't support the necessary semantics actions.

Parameters
`matcher: SemanticsMatcher`	A matcher that identifies the content where the scrollable container needs to scroll to

Returns
`SemanticsNodeInteraction`	The `SemanticsNodeInteraction` that is the receiver of this method. Note that this is not an interaction for the node that is identified by the `matcher`.

): Unit

Rotate the mouse's scrollWheel by the given scrollAmount. The total scroll delta is linearly smoothed out over a stream of scroll events between each scroll event.

Positive scrollAmount values correspond to scrolling forward (new content appears at the bottom of a column, or at the end of a row), negative values correspond to scrolling backward (new content appears at the top of a column, or at the start of a row).

Example of a horizontal smooth scroll:

    smoothScroll(100f, durationMillis = 500L, ScrollWheel.Horizontal)
    // The 100f scroll delta is equally divided into smaller scrolls,
    // such that the time in between two scroll events is more or less
    // equal to the default time between events, 16ms.
}

Parameters
`scrollAmount: Float`	The total delta to scroll the `scrollWheel` by
`durationMillis: Long = DefaultMouseGestureDurationMillis`	The duration of the gesture. By default 300 milliseconds.

    endVelocity: Float,
    durationMillis: Long = 200
): Unit

Performs the swipe gesture on the associated node, such that the velocity when the gesture is finished is roughly equal to endVelocity. The MotionEvents are linearly interpolated between start and end. The coordinates are in the node's local coordinate system, where (0, 0) is the top left corner of the node. The default duration is 200 milliseconds.

Note that due to imprecisions, no guarantees can be made on the precision of the actual velocity at the end of the gesture, but generally it is within 0.1% of the desired velocity.

Parameters
`start: Offset`	The start position of the gesture, in the node's local coordinate system
`end: Offset`	The end position of the gesture, in the node's local coordinate system
`endVelocity: Float`	The velocity of the gesture at the moment it ends. Must be positive.
`durationMillis: Long = 200`	The duration of the gesture in milliseconds. Must be long enough that at least 3 input events are generated, which happens with a duration of 25ms or more.

    start: Offset,
    end: Offset,
    endVelocity: Float,
    durationMillis: Long = VelocityPathFinder.calculateDefaultDuration(start, end, endVelocity)
): Unit

Performs a swipe gesture on the associated node such that it ends with the given endVelocity.

The swipe will go through start at t=0 and through end at t=durationMillis. In between, the swipe will go monotonically from start and end, but not strictly. Due to imprecision, no guarantees can be made for the actual velocity at the end of the gesture, but generally it is within 0.1 of the desired velocity.

When a swipe cannot be created that results in the desired velocity (because the input is too restrictive), an exception will be thrown with suggestions to fix the input.

The coordinates are in the node's local coordinate system, where (0, 0) is the top left corner of the node. The default duration is calculated such that a feasible swipe can be created that ends in the given velocity.

Parameters
`start: Offset`	The start position of the gesture, in the node's local coordinate system
`end: Offset`	The end position of the gesture, in the node's local coordinate system
`endVelocity: Float`	The velocity of the gesture at the moment it ends in px/second. Must be positive.
`durationMillis: Long = VelocityPathFinder.calculateDefaultDuration(start, end, endVelocity)`	The duration of the gesture in milliseconds. Must be long enough that at least 3 input events are generated, which happens with a duration of 40ms or more. If omitted, a duration is calculated such that a valid swipe with velocity can be created.

Throws
`kotlin.IllegalArgumentException`	When no swipe can be generated that will result in the desired velocity. The error message will suggest changes to the input parameters such that a swipe will become feasible.
