Class: TestEngine<T>
Defined in: packages/core/src/TestEngine.ts:12

Inherited from​
overriddenParentLocator()​
overriddenParentLocator():
Optional<PartLocator>
Defined in: packages/core/src/drivers/ComponentDriver.ts:61
Usually this should be undefined as the component driver corresponds to a component nested inside the parent DOM, thus the driver's locator would automatically chain with its parent's locator.
When the component is rendered outside the parent's DOM, which usually happens when the component is a modal or popup, supply the PartLocator on how to locate the component with the component's own locator.
Caution of usage: this function is called before the construction of the driver, so it should not use any instance properties
Returns​
Inherited from​
ComponentDriver.overriddenParentLocator
overrideLocatorRelativePosition()​
overrideLocatorRelativePosition():
Optional<LocatorRelativePosition>
Defined in: packages/core/src/drivers/ComponentDriver.ts:76
Usually this should be undefined when the locator is defined by the ScenePart, thus it reflects the natural relative position of the component
However, in some implementation such as MUI v5 dialog, the actual dialog DOM is rendered outside the parent DOM, and the selector is "siblings", by defining this function, it allows the driver to have the knowledge of the actual relative position instead of offloading the knowledge to the consumer.
Caution of usage: this function is called before the construction of the driver, so it should not use any instance properties
Returns​
Optional<LocatorRelativePosition>
Inherited from​
ComponentDriver.overrideLocatorRelativePosition
runtimeCssSelector()​
runtimeCssSelector():
Promise<string>
Defined in: packages/core/src/drivers/ComponentDriver.ts:251
Get the runtime CSS selector of the component. This is useful for debugging and testing purposes.
Returns​
Promise<string>
The runtime CSS selector of the component
Inherited from​

waitUntilComponentState()​
waitUntilComponentState(
option):Promise<void>
Defined in: packages/core/src/drivers/ComponentDriver.ts:230
Wait until the component is in the expected state such as the component's visibility or existence. If the component has not reached the expected state within the timeout, it will throw an error.
By default it waits until the component is attached to the DOM within 30 seconds.

option​
Partial<Readonly<WaitForOption>> = defaultWaitForOption
The option to configure the wait behavior
Returns​
Promise<void>
Inherited from​
ComponentDriver.waitUntilComponentState
waitUntilVisible()​

timeoutMs):Promise<void>
Defined in: packages/core/src/drivers/ComponentDriver.ts:212
Wait until the component is attached and becomes visible to the DOM.
Parameters​

number = 10000
The number of milliseconds to wait before timing out
Returns​
Promise<void>
