Sprint Integration flow testing with mocked SFTP server?

I have found a mock SFTP server implementation to be used as @Rule injection within JUnit tests. This lets you install a mock SFTP server. For that simply a dependency has to be added to the projects pom.xml with test scope:

        <dependency>
            <groupId>com.github.stefanbirkner</groupId>
            <artifactId>fake-sftp-server-rule</artifactId>
            <version>2.0.1</version>
            <scope>test</scope>
        </dependency>

My integration flow so far is (all the parameters are injected with the @ConfigurationProperties annotation):

@Bean
public SessionFactory<LsEntry> sftpTest1SessionFactory() {
    DefaultSftpSessionFactory sf = new DefaultSftpSessionFactory();
    sf.setHost(hostname);
    sf.setPort(port);
    sf.setUser(username);
    sf.setPassword(password);
    return new CachingSessionFactory<LsEntry>(sf);
}

@Bean
public FireOnceTrigger fireOnceTrigger() {
    return new FireOnceTrigger();
}

@Bean
public IntegrationFlow test1SftpInboundFlow() {
    return IntegrationFlows
        .from(Sftp.inboundAdapter(sftpTest1SessionFactory)
                .preserveTimestamp(true)
                .remoteDirectory(remoteDir)
                .regexFilter(remoteFilePattern)
                .localFilenameExpression(localFile)
                .localDirectory(new File(localDir)),
             e -> e.id("sftpTest1InboundAdapter")
                .autoStartup(true)
                .poller(Pollers.trigger(fireOnceTrigger()))
             )
        .transform(e -> e)
        .handle(m -> System.out.println(m.getPayload()))
        .get();
}

Is it possible to combine my integration flow in a test case with this mocked SFTP server? How would I do this?

Checkout the spring integration unit tests. The ftp unit tests are at...

https://github.com/spring-projects/spring-integration/tree/main/spring-integration-ftp/src/test/java/org/springframework/integration/ftp.

FtpTestSupport shows how they setup an embedded FTP server used by the tests...
