<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>
|
||
$ nix-build '<nixpkgs/nixos/tests/login.nix>'
|
||
</screen>
|
||
|
||
or, if you don’t want to rely on <envar>NIX_PATH</envar>:
|
||
|
||
<screen>
|
||
$ cd /my/nixpkgs/nixos/tests
|
||
$ 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>
|
||
$ firefox result/log.html
|
||
</screen>
|
||
