Function TestJsonbSerializeWithAnyWrapper

testing/go/json_test.go:123–161

TestJsonbSerializeWithAnyWrapper verifies that types.JsonB.SerializeValue handles a sql.AnyWrapper that wraps a JSONDocument containing *apd.Decimal values. This represents the combined Bug 1 + Bug 2 production failure path: 1. A large legacy JSONB value is read from Dolt → *val.ExtendedValueWrappe

(t *testing.T)

//     contains *apd.Decimal for numeric fields.
//  5. ConvertToJsonDocument(*apd.Decimal) must handle that type — previously it did not.
func TestJsonbSerializeWithAnyWrapper(t *testing.T) {
	ctx := sql.NewEmptyContext()

	tests := []struct {
