Demonstrate how the 'Stopwords' setting affects the 'Word density' calculation. First, enter the text 'This is a test sentence to count characters and words.' and note the initial word density for 'is'. Then, add 'is' as a custom stopword and observe how the word density for 'is' changes. Finally, remove 'is' from the stopwords and confirm the word density for 'is' returns to its original state.
Navigate to 'charactercountonline.com'. Enter the text 'This is a test sentence to count characters and words.' into the main text area. Note the word density percentage for the word 'is'. Click the 'Settings' button (ID 17). Locate the 'Add a stopword' input field (implied, as the button ID 431 is for adding). Type 'is' into the stopword input field and add it (assuming interaction with ID 431 or a nearby input). Observe and note the word density percentage for 'is' after it has been added as a stopword. Locate 'is' in the 'Stopwords' dropdown and click the 'Delete a stopword' button (ID 427) next to it. Observe and note the word density percentage for 'is' after it has been removed from stopwords. State the word density for 'is' at each step (initial, after adding as stopword, after removing from stopwords).
The agent successfully enters the specified text into the main input field. The agent correctly identifies the initial word density percentage for 'is' (it should be 10% in the example provided if 'is' is not initially a stopword). The agent successfully adds 'is' as a stopword. The agent confirms that the word 'is' no longer appears in the 'Word density' list or its percentage drops to 0% after being added as a stopword. The agent successfully removes 'is' from the stopwords. The agent confirms that the word 'is' reappears in the 'Word density' list with its original percentage (10%) after being removed from stopwords.
