Writing tests

VMs are created from profiles, booted with hardware options, and shut down when the test is done. Provium cleans up any VMs left running.

Execute shell commands in the guest, parse JSON output, read and write files, inspect kernel logs, and mount virtual filesystems.

Provium provides assert helpers and a test() function for organizing multiple named test cases in a single file.

Fixtures snapshot a booted VM's state so that tests can resume from it instantly instead of cold-booting every time.

Start long-running commands in the background and poll or wait for their completion.

Fork the guest agent into independent worker processes to test multi-process scenarios — credential isolation, inter-process communication, and concurrent access.
