This table provides an overview of the various modules available in the Power Apps Test Engine and their specialized functions.
| Function | Description | Module Link |
|---|---|---|
ConsentDialogFunction |
Checks custom pages of a model-driven app for consent dialogs and handles them automatically during test execution. | testengine.module.mda |
PauseFunction |
Pauses the current test and allows the user to interact with the browser and inspect state when headless mode is false. Useful for debugging tests. | testengine.module.pause |
PlaywrightActionFunction |
Executes Playwright actions for the current page, allowing direct manipulation of DOM elements using CSS and XPath selectors. | testengine.module.playwrightaction |
PlaywrightActionValueFunction |
Executes Playwright actions that require extra value parameters, such as filling form fields or selecting dropdown options. | testengine.module.playwrightaction |
PlaywrightScriptFunction |
Enables execution of custom C# scripts that interact with Playwright APIs, providing maximum flexibility for complex automation scenarios. | testengine.module.playwrightscript |
CheckConnectionExistsFunction |
Checks if a specific connection exists in the Power Platform using the Power Apps portal provider. | testengine.module.powerapps.portal |
CreateConnectionFunction |
Creates Power Platform connections during test execution. Note: This approach should be considered a backup as connections ideally should be created with service principals where possible. | testengine.module.powerapps.portal |
ExportConnectionsFunction |
Exports connection information to a JSON file for documentation or reuse purposes. Compatible with the PowerApps portal provider. | testengine.module.powerapps.portal |
GetConnectionsFunction |
Queries and retrieves available connection information from the Power Platform. Compatible with the PowerApps portal provider. | testengine.module.powerapps.portal |
UpdateConnectionReferencesFunction |
Updates Power Platform connection references. Should be used as a backup approach, as connections ideally should be managed by service principals. | testengine.module.powerapps.portal |
SampleFunction |
A simple sample function that demonstrates how to implement a basic ReflectionFunction. Useful as a starting template for new function development. | testengine.module.sample |
SimulateConnectorFunction |
Enables mocking of connector responses, allowing tests to run without actual external service dependencies. | testengine.module.simulation |
SimulateDataverseFunction |
Provides capabilities to simulate Dataverse responses, enabling testing without actual Dataverse dependencies. | testengine.module.simulation |
VisualCompareFunction |
Performs visual comparison between screenshots using OpenCV, enabling image-based verification of UI elements. | testengine.module.visualcompare |
How to use these functions
These functions are available through the Power Fx Preview namespace when the corresponding modules are enabled. To enable a module in your test settings, add the following to your YAML configuration:
testSettings:
extensionModules:
enable: true
allowPowerFxNamespaces:
- Preview
For example, to use the PlaywrightAction function in your test:
Preview.PlaywrightAction("//button[@id='submit']", "click")
