goal	before no_image notes Make your website be fast for all users and all internet connection speeds—*remember faster is better, less is more.* ### [Performance testing checklist ➔](/topics/performance-checklist/) ### [Advanced performance testing checklist ➔](/topics/advanced-performance-checklist/) true label text Collaboration This is collaborative. You personally won’t be doing all the accessibility testing. We’ll each test other people’s websites to remove any pre-conceived notions about how the site should work.
steps	title before Enable Issues on your repo Before we start anything, everybody needs to go to **their own** repository on [GitHub.com](https://github.com) and enable their Issues tab. **[Video on enabling Issues on GitHub repos ➔](https://www.youtube.com/watch?v=vTULg-7xycs)** title before Determine the performance budget Referring to the [performance testing checklist](/topics/performance-checklist/), we’ll figure out our baseline performance budget what tests to run. *Different people will be assigned different performance tests to cover as much as possible.* title before notes Write down the URL to your website Using a Gist at the front of class, we’ll write down all our URLs so that everybody has access to your website URL for testing. **The URL to this Gist will be displayed on the board so you can get a copy of the list of websites to test.** If you fork the Gist you’ll be able to check off each person as you go. label text Notice You need to know—and add—your own URL. If your name isn’t on that list you won’t get the marks. title before Test everybody’s website With everybody working together your website will be performance tested in lots of different situations. **You’ll be assigned a specific performance test—it will be your job to test everybody’s website using the tool you’re assigned.** *Some tools are a lot of work to test. In those cases the same tool will be distributed to multiple students and the class list will be broken into smaller chunks.* title before Submitting Issues If you find problems with the website you’re testing, create an Issue on GitHub *in their repository.* **[Tutorials on using GitHub Issues ➔](/topics/github-issues/)** --- ### Website URL to repo conversion  1. Cut the username 2. Remove the starting dot 3. Change `io` to `com` 4. Paste the username before the repository name --- ### Create a detailed issue The issue you create for another person’s website should be detailed with at least this information: 1. An informative title 2. A screenshot of the problem—if that makes sense 3. Details and informative description of the problem 4. Any solutions you can think of to help solve the problem *If there already is an Issue for the problem you’re seeing, make a comment on the issue with any extra information you may know.* title before notes Fix problems If there are any problems with your website in a specific tool—fix them! **It’s up to you to make your website work well in all tested situations—we’re developing our websites to empower all humans in the world.** label text Reminder Remember that your website doesn’t have to function exactly the same in every situation—just that it should be functional in every situation.
