如何在java中测试引用当前对象的构造函数？

Question

My code doesn't meet the sonarqube code coverage the following piece of constructor says it needs test in sonarqube, I have written the following code to test it but it is not covering the code? can some one help me where I am going wrong?

@Test
public void OrderBuilderIT() {
    errorQueue.equals("amq:ORDER.T.SYSTEM.ERROR");
}

public OrderBuilder(String errorQueue) {
    this.errorQueue = errorQueue;
}

the code does not seem to be covered

I am assuming that you are trying to test the constructor call for the class with the error queue field value that you are passing while constructing and expecting the same value to be asserted. Actually, your check does nothing in terms of an assertion.

Below is an assumption that you may be trying to achieve. Also, should cover your sonar issue.

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.is;

import org.junit.jupiter.api.Test;
public class SomeConstructorTest {

private OrderBuilder orderBuilder;

 @Test
public void orderBuilderTestWithIncorrectErrorQueueMessage(){
    String expected = "amq:ORDER.T.SYSTEM.ERROR";
    String errorQueue = "dummyString";
    orderBuilder = new OrderBuilder(errorQueue);
    assertThat(expected, is(errorQueue)); // should fail if you are asserting string content
}

}
