/*
* The attrset `exporterTests` contains one attribute
* for each exporter test. Each of these attributes
* is expected to be an attrset containing:
*
* `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
*
* `nodeName` (optional)
* override an incompatible testnode name
*
* Example:
* exporterTests.<exporterName> = {
* exporterConfig = {
* enable = true;
* };
* metricProvider = {
* services.<metricProvider>.enable = true;
* };
* exporterTest = ''
* 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;
* };
* services.<metricProvider>.enable = true;
* };
*
* testScript = ''
* <exporterName>.start()
* <exporterName>.wait_for_unit("prometheus-<exporterName>-exporter.service")
* <exporterName>.wait_for_open_port("1234")
* <exporterName>.succeed("curl -sSf 'localhost:1234/metrics'")
* <exporterName>.shutdown()
