Simplifies small-scale form testing by accepting step-by-step instructions in JSON format. These instructions include CSS selectors, actions (such as text input or clicking), values, and optional delays for realistic timing.

Here's how to get started:

Prepare your instructions in a JSON array format, where each object represents a step in form filling. Specify:

"selector": The CSS selector for the element you want to interact with, e.g., "#nameInput" for an input field with id "nameInput".
"action": Choose from supported actions like "input" for entering text or "click" for simulating a mouse click.
"value": Provide the input value for "input" actions, such as "John Doe". Leave blank for "click" actions.
"delay": Optionally add a delay in seconds for a natural pause between steps.
Save these instructions locally on your machine. The extension will utilize them for automatic form filling when you revisit the same form.

Sample Instructions:
[
  {
    "selector": "#nameInput",
    "action": "input",
    "value": "John Doe",
    "delay": 3
  },
  {
    "selector": ".emailInputClass",
    "action": "input",
    "value": "[email protected]",
    "delay": 3
  },
  {
    "selector": "textarea",
    "action": "input",
    "value": "Hello, this is a test message.",
    "delay": 3
  },
  {
    "selector": "#exampleForm button",
    "action": "click",
    "value": "",
    "delay": 3
  }
]



Sample HTML:
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Example Form</title>
</head>
<body>
  <form id="exampleForm">
    <label for="nameInput">Name:</label>
    <input type="text" id="nameInput" name="name">

    <label for="emailInput">Email:</label>
    <input type="email" id="emailInput" class="emailInputClass" name="email">

    <label for="selectInput">Cars:</label>
    <select name="cars" id="selectInput" class="selectInputClass">
      <option value="volvo">Volvo</option>
      <option value="saab">Saab</option>
      <option value="mercedes">Mercedes</option>
      <option value="audi">Audi</option>
      </select>

    <label for="messageInput">Message:</label>
    <textarea id="messageInput" name="message"></textarea>

    <button id="button-one" type="button">Submit</button>
  </form>
<script src="https://code.jquery.com/jquery-3.7.1.min.js" integrity="sha256-/JqT3SQfawRcv/BIHPThkBvs0OEvtFFmqPF/lYI/Cxo=" crossorigin="anonymous"></script>
  <script>
    $(document).ready(function (e) {
      
$( "#button-one" ).on( "click", function() {
  alert( "Handler for `click` called." );
} );
});
  </script>
</body>
</html>


Activate the extension when encountering the form again. Watch as it seamlessly fills out the form, mimicking human interaction.
