* The attrset `exporterTests` contains one attribute

|

|
|
* `exporterConfig`:
|
|
* this attribute set contains config for the exporter itself
|
|
*
|
|
* `exporterTest`
|
|
* this attribute set contains test instructions
|
|
*
|
|
* `metricProvider` (optional)
|
|
* this attribute contains additional machine config
|
|
*
|
|
* Example:
|
|
* exporterTests.<exporterName> = {
|
|
* exporterConfig = {
|
|
* enable = true;
|
|
* };
|
|
* metricProvider = {

* wait_for_unit("prometheus-<exporterName>-exporter.service")

* wait_for_open_port("1234")
|
|
* succeed("curl -sSf 'localhost:1234/metrics'")
|
|
* '';
|

* # this would generate the following test config:

|
|
* nodes.<exporterName> = {

|
* services.prometheus.<exporterName> = {
|
|
* enable = true;
