Currently the
UnitTestElement
simulates typing into an input by assigning the value character-by-character and dispatching fake events along the way. The problem is that for input types that require the value to be in a particular format (e.g.number
,color
,date
) doing so will temporarily assign an invalid value which will be rejected by the browser with a warning likeThe specified value "12." cannot be parsed, or is out of range.
.This can become a problem for some common use cases like the
ReactiveFormsModule
where a directive might be keeping track of the value by looking at the DOM inside of aninput
event (e.g. theFormControl
directive does this).These changes resolve the issue by looking at the type of the input, and if it's a type that requires a specific format, we assign the value immediately.
Fixes #22129.
