Is there a way to automate user input with JLine's LineReader?

public final class TestCode {
    private TestCode() { }
    public static void main(String[] args) throws IOException {
        String testInputString = "test" + System.lineSeparator() + "test2";
        ByteArrayInputStream input = 
            new ByteArrayInputStream(testInputString.getBytes(StandardCharsets.UTF_8));
        ByteArrayOutputStream output = new ByteArrayOutputStream();
        // Use DumbTerminal for automated input
        Terminal terminal = new DumbTerminal(input, output);
        LineReader lineReader = LineReaderBuilder.builder()
                .terminal(terminal)
                .build();
        System.out.println("Read: " + lineReader.readLine());
        System.out.println("Read: " + lineReader.readLine());
        terminal.close();
    }
}

    public static void main(String[] args) throws IOException {
        PipedInputStream in = new PipedInputStream();
        PipedOutputStream out = new PipedOutputStream(in);
        PrintWriter writer = new PrintWriter(out, true);
        // Write test input to the pipe
        writer.println("test");
        writer.println("test2");
        Terminal terminal = TerminalBuilder.builder()
                .streams(in, System.out)
                .build();
        LineReader lineReader = LineReaderBuilder.builder()
                .terminal(terminal)
                .build();
        System.out.println("Read: " + lineReader.readLine());
        System.out.println("Read: " + lineReader.readLine());
        writer.close();
        terminal.close();
    }
