Use ComponentAssert APIs instead. Because this isn't generated with codegen, it can have subtle issues in tests.

public boolean isEquivalentTo(Component other)

Deprecated.

Description copied from class: Component

Compares this component to a different one to check if they are the same

This is used to be able to skip rendering a component again. We avoid using the Object.equals(Object) so we can optimize the code better over time since we don't have to adhere to the contract required for a equals method.

Specified by:

isEquivalentTo in interface Equivalence<Component>

Overrides:

isEquivalentTo in class Component

Parameters:

other - the component to compare to

Returns:

true if the components are of the same type and have the same props
