I am new to Apache Camel and learn from coding.
My simple router is

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd ">

    <camelContext id="camelContext" xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="timer:timer?repeatCount=1"/>
            <to uri="https://v2.jokeapi.dev/joke/Any"/>
            <log message="${body}"/>
        </route>
    </camelContext>

</beans>

and the test for this router is

@CamelSpringBootTest
public class JokeIT {

    @Autowired
    CamelContext camelContext;

    @Test
    void  test_positive() throws InterruptedException {
        NotifyBuilder notification = new NotifyBuilder(camelContext)
                .from("timer:timer?repeatCount=1").whenDone(1)
                .create();
        camelContext.start();
        notification.matches(10, TimeUnit.SECONDS) ;
        camelContext.stop();
    }

}

Test passed and prints response body as expected.
But what is strange that it passed even with

<to uri="https://v2.jokeapi.dev/joke/Any?proxyAuthHost=abcd"/>

How it can be? Or I missed something?
I expect the test should fail with unavailable proxy.
Thank you in advance.

I tried set proxyHost in query string with the same result.
