Each entering of get_ipython() invocation will have the prompt increased by one. Grouping arbitrary python code into separate cells using with clause.
Examples:
# Usage, before each test function, prepend: @patch('IPython.get_ipython', new_callable=mock_get_ipython) # In the test function's signature, add an argument for the patch, e.g.: def some_test(self, cell): # Group lines of code into a cell using the argument: with cell: # arbitrary python code # ... # arbitrary python code # Next cell with prompt increased by one: with cell: # Auto-incremental # arbitrary python code # ... # arbitrary python code
