What is CSP Tester?
"CSP Tester" is a useful Chrome extension that enables web masters to evaluate the performance and behaviour of their web applications with the implementation of Content Security Policy (CSP) version 2.0. The extension allows users to add URL Patterns, activate the policy, and observe potential CSP violations through the Developer Tools console. The findings help web masters make necessary changes in their policy settings for better security and functionality.

Extension summary
This extension helps web masters to test web application functionality with Content Security Policy (CSP) version 2.0 implemented.
Typical workflow looks like:
- Open the extension window
- Add into the URL Pattern a regular expression for the site that you want to test, for example ://yoursite.com/ (CSP Tester uses Chrome Match Patterns)
- Tick the e.g. "self" checkbox, check "Active" and Save the changes
- Open the Developer Tools and navigate to the tested site
- Confirm a number of CSP violations reported in the Developer Tools Console as well as possible visual changes
- Make changes in the policy based on these reports
User reviews
Very handy! i think the advanced mode is really all you need, weirdly it's way less complex than the default view, the only thing i could ask for is a bigger text box.
Thanks!
