Function TestSpec_PublicAPI_MarshalCompactNoHTMLEscape

pkg/jsonutil/spec_test.go:22–54

TestSpec_PublicAPI_MarshalCompactNoHTMLEscape validates the documented behavior of MarshalCompactNoHTMLEscape as described in the jsonutil README.md. Specification: - Marshals v to compact JSON without HTML escaping. - Characters like '&', '<', '>' are preserved as-is (not encoded to \u0026, \u003c

(t *testing.T)

// - Characters like '&', '<', '>' are preserved as-is (not encoded to \u0026, \u003c, \u003e).
// - Trailing newline emitted by json.Encoder is trimmed so the result matches json.Marshal style.
