Currently developers can use the `By` class to construct common `DebugElement` query predicates. e.g. `By.directive(MyDirective)`. The `directive()` and `all()` predicates are currently returning a predicate that works for `DebugElement` nodes. This return type is too strict since the predicate is not specific to `DebugElement` instances and can also apply to `DebugNode` instances. Meaning that developers are currently able to use the `directive()` predicate when using `queryAllNodes()`. This is a common practice but will break when the project is compiled with TypeScript's `--strictFunctionTypes` flag as the `DebugElement` predicate type is not assignable to predicates for `DebugNode`. In order to make these predicates usable with `--strictFuntionTypes` enabled, we adjust the predicate type to reflect what is actually needed for evaluation of the predicate. PR Close #30993 |
