I've been working for the past two or so weeks on adding the ability to run tests against password-protected sites.
After quite a bit of behind-the-scenes work to store global test parameters and to make them available to the right places at the right time, I'm now happy to say that site-wide and single-URL HTML validation for password-protected sites is available!
For those who don't want to read too much, here's a quick video demonstrating the testing of http://http-auth-02.simplytestable.com/ (username: example, password: password).
Read on to find out what this means (and what it doesn't mean!) and how this lets you test now what you couldn't test before.
What Can Be Tested (And What Cannot)
I mentioned that HTML validation now works for password-protected sites. I need to define what "password-protected" means so that you know what to expect.
You'll most commonly see these means of authentication in cases where your browser itself displays a username/password dialog box directly as opposed to the site you're visiting presenting a nicely-styled login form within a page.
If you've ever edited a
.htaccess file, and possibly generated a corresponding
.htpasswd file, you've been using these means of authentication.
I chose to go with supporting these authentication methods for a couple of reasons:
it's a standards-based approach that requires no special knowledge of the site or page being tested
HTTP authentication is a common approach for temporarily limiting access to publicly-available staging sites (and where such sites can really benefit from thorough testing)
What this new feature covers: any page or site that uses standard HTTP authentication.
What this new feature does not cover: any page or site that uses a custom login form.
Starting a Test For a Password-Protected Site
Below the pre-existing options to select what to test are new options to provide authentication credentials, revealed by clicking 'set authentication options':
Enter the required credentials and then you can start a new test as usual:
You'll notice as you do this that all types of test apart from HTML validation are disabled. At present it is only HTML validation that works flawlessly with password-protected pages and sites.
A Quick Note On Security
The short version: HTTP authentication credentials you provide for the testing of password-protected sites are intentionally not stored securely and are assumed not to provide access to sensitive information.
As noted above, a common use case for HTTP authentication is to provide limited access to a publicly-accessible staging site. This is a common approach for people who develop websites and is precisely the audience we're looking to serve with this new feature.
In such a situation, you put a straightforward authentication system in place to keep your soon-to-be-public but as yet unfinished work from being accessed by the general public.
Such sites are ephemeral in nature, contain information intended eventually for public consumption and which don't inherently hold any details that are intended to be kept private. You'd rather the username and password is not known to everyone but it really doesn't matter if people come to find them out.
We assume HTTP authentication credentials provided to us as a means of allowing you to run automated tests against a password-protected site are not considered sensitive information.
We need to store the credentials you enter to be able to access your password-protected site.
Credentials you enter are stored indefinitely by the core application, that is the central hub of the Simply Testable system that manages tests, so that they can be passed on to the worker applications to carry out the actual testing and to allow you to easily re-test after applying changes.
Credentials are stored temporarily by the worker applications whilst a specific test is being carried out. Once the worker has reported results back to the core application the credentials are deleted.
Credentials are stored in plaintext offering no security should our system databases be accessed directly by a malicious third party.
Credentials are made available to the browser on the test results page to facilitate re-testing. They will be available only to the current user. If you are not logged in, the credentials you entered can be accessed by anyone who views your test results (if you're not signed in, they're not really your results, they're public and belong to everyone).
If you are testing against a public staging site that uses HTTP authentication and if you are comfortable relaying the credentials to a client via email you should already be aware of the fact that the credentials are not sensitive and can be discovered by a range of means independently of us.
