2# `memcachedTestHook` {#sec-memcachedTestHook}
3
4This hook starts a Memcached server during `checkPhase`. Example:
5
6```nix
7{ stdenv, memcachedTestHook }:
8stdenv.mkDerivation {
9
10 # ...
11
12 nativeCheckInputs = [ memcachedTestHook ];
13}
14```
15
16If you use a custom `checkPhase`, remember to add the `runHook` calls:
17```nix
18{
19 checkPhase = ''
20 runHook preCheck
21
22 # ... your tests
23
24 runHook postCheck
25 '';
26}
27```
28
29## Variables {#sec-memcachedTestHook-variables}
30
31Bash-only variables:
32
33 - `memcachedTestPort`: Port to use by Memcached. Defaults to `11211`
34
35Example usage:
36
37```nix
38{ stdenv, memcachedTestHook }:
39stdenv.mkDerivation {
40
41 # ...
42
43 nativeCheckInputs = [ memcachedTestHook ];
44
45 preCheck = ''
46 memcachedTestPort=1234;
47 '';
48}
