How do you copy response values to the clipboard in Postman javascript tests?

I've recently found out about the ability in postman to write pre-request and test scripts using javascript.

I'm trying to figure out if it's possible to copy a value to the clipboard during a test in conjunction with setting the postman environment variable.

For example:

var jsonData = JSON.parse(responseBody);
postman.setEnvironmentVariable ("Action ID", jsonData.ActionId);
// set jsonData.ActionId to clipboard

Solution

There is a way that it could be achieved, by using the visualizer and bringing in the clipboard.js CDN.

This is very basic but by adding this script to the Tests tab, you can see the variable value in the Visualize tab, in the response section.

pm.environment.set("Action_ID", pm.response.json().ActionId);

let template = `
<html>
<head>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/2.0.0/clipboard.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/jquery@3.4.1/dist/jquery.min.js"></script>
</head>
<body>
    <div>
    <div>
        <pre><code style="width:max-content!important;" id="copyText">${pm.environment.get('Action_ID')}</code></pre>
    </div>
    <button class="copyButton" type="button" data-clipboard-action="copy" data-clipboard-target="#copyText" style="background:green;color:white;">Copy to Clipboard</button>
    </div>
</body>
</html>
<script>
    var clipboard = new ClipboardJS('.copyButton');

    clipboard.on('success', function(e) {
        e.clearSelection();
        e.trigger.textContent = '✔ Copied!';
        window.setTimeout(function() {
            e.trigger.textContent = 'Copy to Clipboard';
        }, 2000);
    });
    clipboard.on('error', function(e) {
        e.clearSelection();
        e.trigger.textContent = '✗ Not Copied';
        window.setTimeout(function() {
            e.trigger.textContent = 'Copy to Clipboard';
        }, 2000);
    });

</script>`

pm.visualizer.set(template, pm.response.json())
