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