Cedana Testing

Integration tests are found in integration. Otherwise unit tests are found in this folder for components that require unit tests. Please don't make unit tests for the sake of it.

Dev scripts

On a macbook, it can be difficult to test some of the checkpointing code without launching a full blown vm. Unfortunately orbstack doesn't really cut it here either, since they use a modified kernel.

Good thing we have a way to run instances and load them up with stuff we want to run anywhere :) To spin up a dev environment, simply call cedana-cli run dev.yml, after changing the requisite parameters in the yaml file (such as the branch you want cloned).

You can then call cedana-cli ssh instanceID to get the parameters needed to pass through to your editor. If using VSCode (as the default example shows):

• Click on the green bottom-left square (or view the Remote Explorer tab), which represents the Remote - SSH extension.
• Click on the + symbol to add a new SSH host.
• Enter the SSH command to connect to your remote instance, it will look like ssh -i key.pem user@hostname -p port.
• Select a configuration file to save this setting, usually it's located at ~/.ssh/config.
• You'll see the new SSH host in the SSH Targets section. Click on the folder icon to the right of it to connect.
• VSCode will open a new window and you'll be connected to your remote instance.
