# PromQLsmith
## Description
A random query generator for PromQL. Its name is inspired by [SQLsmith](https://github.com/anse1/sqlsmith)
## Usage
PromQLsmith is a library that can be used in the test to generate PromQL queries. Example usage can be found under [example](example).
```go
package main
import (
"fmt"
"math/rand"
"time"
"github.com/prometheus/prometheus/model/labels"
"github.com/cortexproject/promqlsmith"
)
func main() {
seriesSet := []labels.Labels{
labels.FromMap(map[string]string{
labels.MetricName: "http_requests_total",
"job": "prometheus",
"status_code": "200",
}),
labels.FromMap(map[string]string{
labels.MetricName: "http_requests_total",
"job": "prometheus",
"status_code": "400",
}),
}
rnd := rand.New(rand.NewSource(time.Now().Unix()))
opts := []promqlsmith.Option{
promqlsmith.WithEnableOffset(true),
promqlsmith.WithEnableAtModifier(true),
}
ps := promqlsmith.New(rnd, seriesSet, opts...)
// Generate a query that can be used in instant query.
q1 := ps.WalkInstantQuery()
// Generate a query that can be used in range query.
q2 := ps.WalkRangeQuery()
fmt.Println(q1.Pretty(0))
fmt.Println(q2.Pretty(2))
}
```
