(Redirected from QA:Testcase USB stick DVD dd)
Description
This test verifies that a Fedora ISO image can be written to a USB stick with the dd
command, and successfully boots and installs.
Setup
- Download the Fedora image you wish to test.
- Ensure you have a USB stick larger than the image file, and whose contents you can afford to lose (the contents of the stick will be destroyed as a part of the test).
- Ensure you have an existing Linux (or other Unix) system with the
dd
command available.
How to test
- Write the image image to the USB stick using
dd
.- Example command is:
dd if=Fedora-Workstation-Live-x86_64-42-1.1.iso of=/dev/sdX bs=16M status=progress oflag=direct
where you replace sdX by your USB stick device identifier. This will destroy all data on that disk. - A longer guide how to use this command is available at How to create and use Live USB#dd.
- Example command is:
- Boot the system from the USB stick.
- If testing a live image, start the installer.
- Proceed with the installation.
Expected Results
- The image is written to the USB stick without error.
- The stick boots without error.
- The installer starts without error.
- The installation finishes successfully, and if a DVD image was used, uses the package repository on the USB stick (not a network repository).
- The new system initiates boot properly. Note that problems after boot that do not seem to be related to writing the image to a USB stick are likely out of the scope of this test case, though they may count as failures of one of the other installation validation test cases. If you observe the same failure booting the image in a virtual machine or from an optical disc, it is likely not a failure of this test case.
