Prometheus alert Unit testing

[Travel & Devops]

Hello Team ,

I am planning to write prometheus unit test cases for my alert rule , i want to write prometheus unit test cases for below alert rule ,

( sum(rate(grpc_server_handling_seconds_bucket{endpoint="http",grpc_method="ActivateService",grpc_service="ibm.commonservice.v1.CommonService",grpc_type="unary",job="ibm-adns-api-service",le="1",service="ibm-adns-api-service"}[15m])) by (job)+sum(rate(grpc_server_handling_seconds_bucket{endpoint="http",grpc_method="ActivateService",grpc_service="ibm.commonservice.v1.CommonService",grpc_type="unary",job="ibm-adns-api-service",le="5",service="ibm-adns-api-service"}[15m])) by (job) ) / 2 /  sum(rate(grpc_server_handling_seconds_count{endpoint="http",grpc_method="ActivateService",grpc_service="ibm.commonservice.v1.CommonService",grpc_type="unary",job="ibm-adns-api-service",service="ibm-adns-api-service"}[15m])) by (job) < 0.9

I have written below test cases , can you please help me how to calculate test case values .

rule_files:

  - alert.rules

evaluation_interval: 1m

tests:

  - interval: 1m

    input_series:

      - series: 'grpc_server_handling_seconds_bucket{endpoint="http",grpc_method="ActivateService",grpc_service="ibm.commonservice.v1.CommonService",grpc_type="unary",job="ibm-adns-api-service",le="1",service="ibm-adns-api-service"}'

        values: '1 1+0x2 0+0x12'

      - series: 'grpc_server_handling_seconds_bucket{endpoint="http",grpc_method="ActivateService",grpc_service="ibm.commonservice.v1.CommonService",grpc_type="unary",job="ibm-adns-api-service",le="5",service="ibm-adns-api-service"}'

        values:  0 0+0x2 1+1x12

      - series: 'grpc_server_handling_seconds_count{endpoint="http",grpc_method="ActivateService",grpc_service="ibm.commonservice.v1.CommonService",grpc_type="unary",job="ibm-adns-api-service",service="ibm-adns-api-service"}'

        values:  1 1+0x14

    alert_rule_test:

      - eval_time: 15m

        alertname: ADNSAPISlowUnaryQueries of operation ActivateService

        exp_alerts:

          - exp_labels:

              severity: warning

              endpoint: 'http'

              grpc_method: 'ActivateService'

              grpc_service: 'ibm.commonservice.v1.CommonService'

              grpc_type: 'unary'

              job: 'ibm-adns-api-service'

              service: 'ibm-adns-api-service'

            exp_annotations:

              summary: "Detected slow response time from the operation ActivateService"
