Я получаю org.junit.platform.commons.PreconditionViolationException в приведенном ниже коде

Я пытаюсь реализовать параметризованный метод тестирования в Junit5.

Внутри параметризованного метода я заполню HashMap подходящими значениями переменных и передам его тестовому методу параметрыToTestExpressionEvaluator() класса ExpressionEvaluatorTest, который проверит заявленное значение.

Но я получаю эту ошибку. Есть ли способ, которым я могу успешно передать HashMap.

Это мой код:

import org.apache.log4j.Logger;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.MethodSource;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import java.util.HashMap;
import java.util.Map;
import static org.junit.jupiter.api.Assertions.assertEquals;

/**
 * ExpressionEvaluatorTest
 * to test the ExpressionEvaluator.class
 */
@RunWith(Parameterized.class)
class ExpressionEvaluatorTest {

    private final Logger logger = Logger.getLogger(ExpressionEvaluatorTest.class);

    /**
     *
     * @return the map of variable values
     * to get defined variable values
     */
    static Map<String, Integer> parametersToTestExpressionEvaluator() {
        HashMap<String, Integer> mapper = new HashMap<>();
        mapper.put("a", 1);
        mapper.put("b", 3);
        mapper.put("c", 3);
        mapper.put("d", 1);
        mapper.put("e", 1);
        return mapper;
    }

    @ParameterizedTest
    @MethodSource("parametersToTestExpressionEvaluator")
    void checkingBracketWithDivision(HashMap<String, Integer> valueMapper){
        ExpressionEvaluator testObj = new ExpressionEvaluator("(a)+(b-c/d)/(-e)");
        logger.info("Checking Brackets with Division");
        assertEquals(1, testObj.evaluate(valueMapper));
    }
}

Это сообщение об ошибке, которое я получаю:
