@Test
public void givenPythonScript_whenPythonProcessInvoked_thenSuccess() throws Exception {
    ProcessBuilder processBuilder = new ProcessBuilder("python", resolvePythonScriptPath("hello.py"));
    processBuilder.redirectErrorStream(true);

    Process process = processBuilder.start();
    List<String> results = readProcessOutput(process.getInputStream());

    assertThat("Results should not be empty", results, is(not(empty())));
    assertThat("Results should contain output of script: ", results, hasItem(
      containsString("Hello Baeldung Readers!!")));

    int exitCode = process.waitFor();
    assertEquals("No errors should be detected", 0, exitCode);
}
