Question

Determine if the web driver is operational within Robot Framework

My Robot Framework test cases are ready to go, but I'm facing a structure dilemma in my project setup. Here's how it looks:

TestProject
|__ TestScenarios
    |__ TestCategory1
    |__ TestCategory2
    |__ __init__.py
|__ RunTest.py

I have a special suit setup that opens the browser with a specific URL and a suit teardown that closes all open browsers in __init__.py. I use RunTest.py to execute my test cases, where I define which directories should be included or excluded in tests, along with other preferences.

The issue arises when I set sub-directories for testing in RunTest.py, as the __init__.py file from those subdirectories isn't called - resulting in no open browsers. Adding more __init__.py files into each sub-directory creates another problem of multiple browsers opening when running tests from the top directory.

My solution is to include one __init__.py file in each sub-directory, with a check to see if a browser is already open. If it is, continue with the existing browser; if not, open a new one. This way, I can seamlessly switch between directories without browser conflicts.

Any suggestions on how I can implement this approach described above?

To ensure that a browser is open before running specific keywords, one approach could be to execute a predefined keyword that requires a browser window to be active. If the keyword fails, it indicates no browser is open and prompts the system to launch one. On the other hand, if the keyword succeeds, no action is taken.

An implementation of this concept may resemble the following example:

*** Keywords ***
| Check browser status
| | # Define behavior on failure for capturing screenshots
| | ${failed_keyword}= | Register failure handling | Do nothing
| | 
| | # Execute a keyword and record its status
| | ${current_status}= | run keyword and return status | Get Window Handles
| | 
| | # Revert to the initial failure handling setup
| | Register failure handling | ${failed_keyword}
| | 
| | # Proceed if the keyword execution is successful, assuming an active browser
| | Run keyword unless | ${current_status} == False | Exit keyword execution 
| | 
| | # No existing browser found, trigger browser launch
| | Log | No previous browser session detected
| | Open browser | https://www.example.com | firefox

In my view, a reliable strategy involves executing tests from the root directory and utilizing command line arguments along with tags to execute specific test suites effectively.

To monitor running processes and check if your browser is open, you can utilize the subprocess module:

import subprocess

def check_processes(proc_name, flag=False):
   p = subprocess.Popen(['ps','-A'], stdout=subprocess.PIPE)
   out, err = p.communicate()
   for line in out.splitlines():
      if proc_name in line:
          print(line)
          flag=True
          # continue with current process
          #pid = int(line.split(None, 1)[0]) if you need pid 
   if not flag:
          #start new process

If you need to terminate a process, you can use os.kill along with subprocess.signal.SIGKILL:

os.kill(pid, subprocess.signal.SIGKILL)
