SpringBoot Autoconfigured bean is missing in tests after migration to 3.0

I've been migrating from Spring Boot 2.6 and ran into an issue where brave.propagation.CurrentTraceContext can be injected in runtime but fails in tests.

package com.example.braveautoconftestproblem;

import brave.propagation.CurrentTraceContext;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class BraveAutoconfTestProblemApplication {

    public BraveAutoconfTestProblemApplication(CurrentTraceContext currentTraceContext) {
        System.out.println(currentTraceContext);
    }

    public static void main(String[] args) {
        SpringApplication.run(BraveAutoconfTestProblemApplication.class, args);
    }

}

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'braveAutoconfTestProblemApplication': Unsatisfied dependency expressed through constructor parameter 0: No qualifying bean of type 'brave.propagation.CurrentTraceContext' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'brave.propagation.CurrentTraceContext' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

Minimal project in attachment: brave-autoconf-test-problem.zip

When started with debug=true it doesn't even process BraveAutoConfiguration.

I looked at migration guide but didn't find anything related to testing.

This is by design. As described in the documentation, you need to use @AutoConfigureObservability to enable tracing in a @SpringBootTest.
