Examples of org.zeroturnaround.exec.stream.PumpStreamHandler

org.zeroturnaround.exec.stream.PumpStreamHandler
Copies standard output and error of subprocesses to standard output and error of the parent process. If output or error stream are set to null, any feedback from that stream will be lost.

  @Test
  public void testPumpFromInputToOutput() throws Exception {
    String str = "Tere Minu Uus vihik";
    ByteArrayInputStream bais = new ByteArrayInputStream(str.getBytes());
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    PumpStreamHandler handler = new PumpStreamHandler(baos, System.err, bais);


    ProcessExecutor exec = new ProcessExecutor("java", "-cp", "target/test-classes",
        PrintInputToOutput.class.getName()).readOutput(true);
    exec.streams(handler);
