Requirements for running Selenium Test Cases

• Python3.x
• python modules:
  • selenium
  • webdriver_manager
  • nose
• Check and updated config.py if needed with correct server value
• Run nosetests -vds --with-xunit test_app.py
• After the execution of results, a result file nosetests.xml would be created in the folder from where the tests are being executed.
