Before you set your site loose for everyone to look at, you should perform some tests. Even if your site seems to work fine on your computer, it is not so easy to ensure that it will work as well on other people’s computers.
After all, different people have different makes and versions of browsers, different speed Internet
connections, and different screen sizes and resolution, so what worked on your computer might not work as well for other people on their machines. So, the two stages of testing are as follows:
- Pre-publishing tests: These are performed on your computer before asking anyone else to look at the site.
- Pre-release tests: Performed on the site exactly as it will be published on the Web (on a web server).
