title: Capture behave outputs into a dynamically created log file
body: <p>I am trying to capture the Behave outputs in a file(let's say a log file). I am  dynamically creating a new log file at '@then' step for every run of Behave based on datetime. Below is the sample code given in the steps/xx.py file.</p>
  
  <pre><code>def filecreation(filename):
      chwd=os.chdir('C:\\Users\\xxx\\Desktop\\features\\test_features')
      with open(filename, 'w+') as d:
          pass
  
  cur_ts = datetime.datetime.now()
  log_time_stamp = str(cur_ts).split('.')[0].replace(' ',':').replace('-',':').replace(':','')
  file_name = 'ATMorFrameRelay' + log_time_stamp + '.log'
  filecreation(file_name)
  pass
  </code></pre>
  
  <p>Now i am trying to send the Behave output at every run to the log file created above. I am aware that the command "Behave -o [file name]" will create a file for every run , but thought will rather send the STDOUT to the above created file for every new run. Also is it fine/safer to use the STDOUT to write into files in a production like environment and not cause any issues.</p>
  
  <p>I am a newbie to both Python and Behave, so looking forward for any solution/suggestions on how it can be achieved. Any relevant materials or information will be really appreciated too.</p>
  
  <p>Thanks in advance</p>
