At the time of this writing, the latest stable version of Debian is Debian 9.4 codename Stretch. Debian Testing is the testing release of the next version of Debian, which is at the time of this writing Debian 10 codename Buster. Even though it's called Debian Testing, many people said it's working just fine. In Debian Testing, you get newer version of the utilities in Debian, as you know Debian Stable uses older version of every package.

In this article, I will show you how to download and install Debian Testing on your computer. Let's get started.

Downloading Debian Testing:

You can download Debian Testing weekly builds or daily builds.

To download Debian Testing weekly builds, go to http://cdimage.debian.org/cdimage/weekly-builds/

To download Debian Testing daily builds, go to http://cdimage.debian.org/cdimage/daily-builds/

I prefer the weekly builds, because I can download Debian Testing CD image with desktop environment included. It's easier to install without internet connection. The daily builds mostly have net install images, which I don't like. You may have different opinion. That's fine.

For more information, go to https://wiki.debian.org/DebianTesting

If you go to the Debian Testing weekly builds link http://cdimage.debian.org/cdimage/weekly-builds/, you show see the following page. Select your desired architecture. I am going to download the 64-bit version of Debian Testing. So I am selecting amd64. For 32-bit version, select i386.

Now you can download either a CD image of Debian Testing, or a DVD image of Debian Testing. The DVD image is about 3.7 GB in size. The download should take a long time. So I went for the CD image. But DVD image would work just fine. Select either iso-cd for Debian Testing CD image or iso-dvd for Debian Testing DVD image.

Note: If you want to download Debian Testing DVD image, you only need to download the first DVD image, for example debian-testing-amd64-DVD-1.iso, you can leave the others.

Now you should see the following page.

Scroll down a little bit and click on the CD image debian-testing-amd64-xfce-CD-1.iso as marked in the screenshot below.

Your download should start.

Making Debian Testing Bootable USB Drive:

You can write the ISO image to a CD/DVD or you can make a bootable USB drive with Rufus from Windows operating system. In this section, I am going to show you how to make bootable USB drive with Rufus.

First go to the official website of Rufus at https://rufus.akeo.ie/ and go scroll down to the Download section. Now click on Rufus Portable link as marked in the screenshot below.

Click on Yes.
