<title>Running Tests</title>
<para>
You can run tests using <command>nix-build</command>. For example, to run the
test
<filename
xlink:href="https://github.com/NixOS/nixpkgs/blob/master/nixos/tests/login.nix">login.nix</filename>,
you just do:
<screen>
<prompt>$ </prompt>nix-build '&lt;nixpkgs/nixos/tests/login.nix>'
</screen>
or, if you dont want to rely on <envar>NIX_PATH</envar>:
<screen>
<prompt>$ </prompt>cd /my/nixpkgs/nixos/tests
<prompt>$ </prompt>nix-build login.nix
running the VM test script
machine: QEMU running (pid 8841)
6 out of 6 tests succeeded
</screen>
After building/downloading all required dependencies, this will perform a
build that starts a QEMU/KVM virtual machine containing a NixOS system. The
virtual machine mounts the Nix store of the host; this makes VM creation very
fast, as no disk image needs to be created. Afterwards, you can view a
pretty-printed log of the test:
<screen>
<prompt>$ </prompt>firefox result/log.html
</screen>
