webboot

README

Usage

The webboot program would do the following:

• Present a menu with the existing cached distro options
• If the user wants a distro that is not cached, they can download an ISO
• After the user decides on an ISO, boot it.

Test

Our UI uses a package called Termui. Termui will parse the standard input into keyboard events and insert them into a channel, then from which the Termui get it's input. For implement a unattended test, I manually build a series of keyboard events that reperesent my intented input for test, and insert them into a channel. Then I replace the original input channel with my channel in the test. So the go test could run a test of ui automatically.

See TestDownloadOption for an example:

• create a channel by make(chan ui.Event).
• use go pressKey(uiEvents, input) to translate the intented test input to keyboard events and push them to the uiEvents chanel.
• use the uiEvents channel by call downloadOption.exec(uiEvents). (Main function will always call ui.PollEvents() to get the sandard input channel)
• all functions involving in ui input will provide a argument to indicate the input chanel.

Hint

If want to set up a cached directory in side the USB stick, the file structure of USB stick should be +-- USB root | +-- Images (<--- the cache directory. It must be named as "Images") | +-- subdirectories or iso files ...
