jOOQ поставляется с MockConnection, который может быть снабжен MockDataProvider, который гораздо проще реализовать, чем полный JDBC API. Этот пост показывает, как использовать MockConnection:
http://blog.jooq.org/2013/02/20/easy-mocking-of-your-database/
Пример:
MockDataProvider provider = new MockDataProvider() {
// Your contract is to return execution results, given a context
// object, which contains SQL statement(s), bind values, and some
// other context values
@Override
public MockResult[] execute(MockExecuteContext context)
throws SQLException {
// Use ordinary jOOQ API to create an org.jooq.Result object.
// You can also use ordinary jOOQ API to load CSV files or
// other formats, here!
DSLContext create = DSL.using(...);
Result<MyTableRecord> result = create.newResult(MY_TABLE);
result.add(create.newRecord(MY_TABLE));
// Now, return 1-many results, depending on whether this is
// a batch/multi-result context
return new MockResult[] {
new MockResult(1, result)
};
}
};
// Put your provider into a MockConnection and use that connection
// in your application. In this case, with a jOOQ DSLContext:
Connection connection = new MockConnection(provider);
DSLContext create = DSL.using(connection, dialect);
// Done! just use regular jOOQ API. It will return the values
// that you've specified in your MockDataProvider
assertEquals(1, create.selectOne().fetch().size());
Существует также MockFileDatabase, который помогает сопоставить фиктивные результаты со строками SQL, написав текстовый файл, подобный следующему:
# This is a sample test database for MockFileDatabase
# Its syntax is inspired from H2's test script files
# When this query is executed...
select 'A' from dual;
# ... then, return the following result
> A
> -
> A
@ rows: 1
# Just list all possible query / result combinations
select 'A', 'B' from dual;
> A B
> - -
> A B
@ rows: 1
select "TABLE1"."ID1", "TABLE1"."NAME1" from "TABLE1";
> ID1 NAME1
> --- -----
> 1 X
> 2 Y
@ rows: 2
