Java validate graphQL query syntax in unit test

When writing a GraphQL-client that builds query strings manually, is there a way to write unit tests that checks that the syntax of a graphQL query is valid? Like using some official parser and checking it does not find syntax errors?

Usage of libraries is allowed in the answer, (though obviously if it's a library to not use raw strings to write queries, then the question becomes moot).

Seems this might work, including graphql-java library:

<!-- https://mvnrepository.com/artifact/com.graphql-java/graphql-java -->
<dependency>
    <groupId>com.graphql-java</groupId>
    <artifactId>graphql-java</artifactId>
    <version>2020-05-19T06-33-01-57ce5cf</version>
</dependency>

The parse the query.

graphql.parser.Parser graphQLParser = new Parser();
// assert no exception
graphQLParser.parseDocument(queryString);
