Class: TestEngine<T>
Defined in: packages/core/src/TestEngine.ts:12
Root driver used for driving a complete scene in a test. It inherits all functionality from ComponentDriver and adds a clean up hook so that tests can reliably dispose of resources.

drag()​
drag(
delta):Promise<void>
Defined in: packages/core/src/drivers/ComponentDriver.ts:279
Drag this component by the given pixel delta from its center. See Interactor.drag.
Prefer a keyboard-driven setValue over a true drag in real drivers — these
drag primitives exist only for cases keyboard cannot express (e.g. panning a
Lightbox, reordering a column). jsdom has no layout engine, so the positional
outcome of the drag is E2E-only there.
Parameters​
delta​
Pixel offset to drag by
Returns​
Promise<void>
Inherited from​
dragTo()​
dragTo(
target):Promise<void>
Defined in: packages/core/src/drivers/ComponentDriver.ts:265
Drag this component and drop it onto another component. See Interactor.dragTo.
Prefer a keyboard-driven setValue over a true drag in real drivers — these
drag primitives exist only for cases keyboard cannot express (e.g. panning a
Lightbox, reordering a column). jsdom has no layout engine, so the positional
outcome of the drag is E2E-only there.
Parameters​

Returns​
Promise<void>

Promise<void>
Inherited from​

overriddenParentLocator()​
staticoverriddenParentLocator():Optional<PartLocator>
Defined in: packages/core/src/drivers/ComponentDriver.ts:77
Portal hook: where to re-root this driver's locator when its component renders
outside the parent's DOM (a modal, popup, drawer). Return the PartLocator
that locates the component from the document root, or undefined (the default)
for normal in-tree components whose locator chains from the parent.
This is static because it is per-class metadata read off the constructor
before any instance exists — which makes the "no instance state" constraint
structural rather than a documented caution. Override with static override.
Returns​
Inherited from​
ComponentDriver.overriddenParentLocator
overrideLocatorRelativePosition()​
staticoverrideLocatorRelativePosition():Optional<LocatorRelativePosition>
Defined in: packages/core/src/drivers/ComponentDriver.ts:90
Portal hook: the locator relative position to apply when the component's real
DOM is a sibling/elsewhere rather than a descendant (e.g. a MUI dialog rendered
at the document root, located by a "Same"-level selector). Return undefined
(the default) to keep the natural position declared by the ScenePart.
Static for the same reason as ComponentDriver.overriddenParentLocator:
it is class-level metadata read before construction. Override with static override.
Returns​
Optional<LocatorRelativePosition>
