Docs discourage using of NO_ERRORS_SCHEMA #49269
Description
Describe the problem that you experienced
There are two places in the docs that cover NO_ERRORS_SCHEMA.
The API page for NO_ERRORS_SCHEMA says
The usage of this schema is generally discouraged because it prevents useful validation and may hide real errors in your template
It sounds like a developer should avoid using it, not mentioning the applicability context (this is true for app code, but less so for unit tests).
The "Component testing scenarios" page. This one has more permissive language and warns about **over-**using it. Yet, it doesn't explain when it's appropriate to use it, so overall it discourages developers from using it in unit tests, again.
Additionally, the justification it provides is "it disables compile-time checks". However, since the full app is still AOT-compiled, and NO_ERRORS_SCHEMA is only used in the component testing scenario, it doesn't sound like a problem to me.
