Walk through a few schema changes and familiarize yourself with GraphOS schema checks.

Situation 1

Remove the description for a field, then run a schema check.

Which of the following schema checks pass?

Linter checksBuild checksOperation checksNone of the checks

Undo your changes for the next question.

Situation 2

Add the following to your schema:

schema.graphql

type Chef {
  FirstName: String
}

Run a schema check.

Which of the following linter check rules would throw a warning?

FIELD_NAMES_SHOULD_BE_CAMEL_CASEDEFINED_TYPES_ARE_UNUSEDALL_ELEMENTS_REQUIRE_DESCRIPTIONDOES_NOT_PARSETYPE_NAMES_SHOULD_BE_PASCAL_CASE

Why does the overall schema check pass?

The linter check rules in violation are set to "warn" onlySchema additions don't result in operation check failuresSchema additions for a supergraph with a single subgraph don't result in build check errors

Undo your changes for the next question.

Situation 3

Remove the cookingTime field, along with its description. Run a schema check. Open up the check in Studio and select one of the affected operations.

Click "Override", then "Mark changes as safe".

Re-run the check using Studio.

TODO: Validate if this is a likely scenario - depending on which operations they've ran, this could be not a great situation to try and recreate...

Which of the following statements are true after re-running the check?

The operation marked as safe won't show up under "Affected operations" anymoreThe operation still shows up under "Affected operations"Build checks passLinter checks pass
