<title>Running Tests interactively</title>
|
|
|
|
<para>The test itself can be run interactively. This is
|
|
particularly useful when developing or debugging a test:
|
|
|
|
<screen>
|
|
$ nix-build nixos/tests/login.nix -A driver
|
|
$ ./result/bin/nixos-test-driver
|
|
starting VDE switch for network 1
|
|
>
|
|
</screen>
|
|
|
|
You can then take any Perl statement, e.g.
|
|
|
|
<screen>
|
|
> startAll
|
|
> testScript
|
|
> $machine->succeed("touch /tmp/foo")
|
|
</screen>
|
|
|
|
The function <command>testScript</command> executes the entire test
|
|
script and drops you back into the test driver command line upon its
|
|
completion. This allows you to inspect the state of the VMs after the
|
|
test (e.g. to debug the test script).</para>
|
|
|
|
<para>To just start and experiment with the VMs, run:
|
|
|
|
<screen>
|
|
$ nix-build nixos/tests/login.nix -A driver
|
|
$ ./result/bin/nixos-run-vms
|
|
</screen>
|
|
|
|
The script <command>nixos-run-vms</command> starts the virtual
|
|
machines defined by test. The root file system of the VMs is created
|
|
on the fly and kept across VM restarts in
|
|
<filename>./</filename><varname>hostname</varname><filename>.qcow2</filename>.</para>
