Most interesting parts:

Fake SMTP Server

var container = new FakeSMTPTestContainer()
 .withSmtpPassword("pwd")
 .withSmtpUser("test_user");
container.start();
container.waitForReadyState();
// sending emails to this server
// checking API
var count = container.getEmailCountFrom("from@test.com");
// clearing API
container.deleteEmails();

Classpath Scanner API

var scanner = ClassPathScannerFactory.newDefaultScanner();
scanner.setUseSystemClasspath(true);
scanner.scan();
var implementations = scanner.findImplements(Collection.class);
var inherited = scanner.findInherited(AbstractArray.class);

Compiler API

var javaSource = getClass().getResource("/java/source/TestCompileJavaSource.java");
var compiler = CompilerFactory.newDefaultCompiler();
var compiled = compiler.compile(javaSource.toURI());
var instance = ClassUtils.newInstance(compiled[0]);
var method = instance
 .getClass()
 .getMethod("makeString");
var result = method.invoke(instance); 

Logger API

// getting logger by class/name
var logger = LoggerManager.getLogger(getClass());
// global enable/disable debug level
LoggerLevel.DEBUG.setEnabled(true);
logger.debug("Simple message");
logger.debug(5, (val) -> "Lazy message with 5: " + val);
logger.debug(5, "Lazy message with 5:%d"::formated);
logger.debug(5, 10D, (val1, val2) -> "Lazy message with 5: " + val1 + " and 10: " + val2);
logger.debug(5, 10D, "Lazy message with 5:%d and 10:%d"::formatted);
// global disable debug level
LoggerLevel.DEBUG.setEnabled(false);
// local enable debug level only for this logger instance
logger.setEnabled(LoggerLevel.DEBUG, true);

Mail Sender

var config = MailSenderConfig
 .builder()
 .from("from@test.com")
 .host("smtp.test.com")
 .port(smtpPort)
 .password(smtpPassword)
 .username(smtpUser)
 .useAuth(true)
 .enableTtls(true)
 .sslHost("smtp.test.com")
 .build();
var javaxConfig = JavaxMailSender.JavaxMailSenderConfig
 .builder()
 .executorKeepAlive(120)
 .executorMaxThreads(20)
 .executorMinThreads(1)
 .build();
var sender = new JavaxMailSender(config, javaxConfig);
sender.send("to@test.com","Test Subject","Content");
sender
 .sendAsync("to@test.com","Test Subject","Content")
 .thenAccept(aVoid -> System.out.println("done!"));

Network API

Simple String Echo Server/Client

var serverNetwork = NetworkFactory.newStringDataServerNetwork();
var serverAddress = serverNetwork.start();
serverNetwork
 .accepted()
 .flatMap(Connection::receivedEvents)
 .subscribe(event -> {
 var message = event.packet.getData();
 System.out.println("Received from client: " + message);
 event.connection.send(new StringWritablePacket("Echo: " + message));
 });
var clientNetwork = NetworkFactory.newStringDataClientNetwork();
clientNetwork
 .connected(serverAddress)
 .doOnNext(connection -> IntStream
 .range(10,100)
 .forEach(length -> connection.send(new StringWritablePacket(StringUtils.generate(length)))))
 .flatMapMany(Connection::receivedEvents)
 .subscribe(event -> System.out.println("Received from server: " + event.packet.getData()));
