Schema:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "if": {
      "properties": {
          "foo": { "const": "then" }
      },
      "required": ["foo"]
  },
  "else": {
      "properties": {
          "baz": { "type": "string" }
      },
      "required": ["baz"]
  },
  "unevaluatedProperties": false
}

Instance:

"tests": [
    {
        "description": "when if is true and has no unevaluated properties",
        "data": {
            "foo": "then",
            "bar": "bar"
        },
        "valid": false
    },
    ...
]

The description of the above test states that it has no unevaluated properties, but isn't the bar property here unevaluated?

I agree that it's wrong, but I think the test is wrong, not the description. The test should be updated to match the description.

[gregsdennis]

The test case is right, technically (but there may also be an error in expressing the intent).

bar is never defined, so in that regard, the test is correct.

However, the test might have meant baz instead of bar. In that case, /else is skipped when /if is true. Because baz is defined only in the else subschema (which isn't evaluated), it remains unevaluated.

[jdesrosiers]

You're right, but that's not what I meant. Look at all the descriptions for all the tests. It's a matrix of the possibilities of two variables: (1) if result (2) unevaluated properties result.

• when if is true and has no unevaluated properties
• when if is true and has unevaluated properties
• when if is false and has no unevaluated properties
• when if is false and has unevaluated properties

The test should be changed to actually test what the description says otherwise it's just a another test for "when if is true and has unevaluated properties", which is already covered.
