# k6 Extension for Diameter
## Overview
This extension adds support for the Diameter protocol to [k6](https://k6.io/).
## Build
```bash
make
```
The Makefile will automatically download [xk6](https://github.com/grafana/xk6), which is required to compile this project.
## Example
```js
import diam from 'k6/x/diameter'
import avp from 'k6/x/diameter/avp'
import dict from 'k6/x/diameter/dict'
import { cmd, app, code, flag, vendor } from './diam/const.js'
import { check } from 'k6'
let data = diam.DataType()
let client = diam.Client({
authApplicationId: [app.ChargingControl],
})
export default function () {
client.connect("localhost:3868")
let ccr = diam.newMessage(cmd.CreditControl, app.ChargingControl);
ccr.add(avp.New(code.OriginHost, 0, 0, data.DiameterIdentity("origin.host")))
ccr.add(avp.New(code.OriginRealm, 0, 0, data.DiameterIdentity("origin.realm")))
ccr.add(avp.New(code.DestinationHost, 0, 0, data.DiameterIdentity("dest.host")))
ccr.add(avp.New(code.DestinationRealm, 0, 0, data.DiameterIdentity("dest.realm")))
ccr.add(avp.New(code.SessionId, 0, flag.M, data.UTF8String("Session-8888")))
ccr.add(avp.New(code.CCRequestType, 0, flag.M, data.Enumerated(1)))
ccr.add(avp.New(code.CCRequestNumber, 0, flag.M, data.Unsigned32(1000)))
ccr.add(avp.New(code.SubscriptionId, 0, flag.M, data.Grouped([
avp.New(code.SubscriptionIdData, 0, flag.M, data.UTF8String("subs-data")),
avp.New(code.SubscriptionIdType, 0, flag.M, data.Enumerated(1))
])))
ccr.add(avp.New(code.ServiceInformation, 10415, flag.M, data.Grouped([
avp.New(code.PSInformation, 10415, flag.M, data.Grouped([
avp.New(code.CalledStationId, 0, flag.M, data.UTF8String("10099"))
]))
])))
const cca = client.send(ccr)
console.log(`CCA: ${cca}`)
const resultCode = cca.findAVP(code.ResultCode, 0)
check(resultCode, {'Result-Code == 2001': r => r == 2001,})
}
```
Use your custom k6 binary to run an example k6 script.
```bash
./bin/k6 run example/example.js
```
## Docker
Alternatively, you may run xk6-diameter packaged in Docker using the following command:
```bash
docker run \
--net=host \
-v $(pwd)/example:/mnt/example \
ghcr.io/matrixxsoftware/xk6-diameter run --log-format=raw /mnt/example/example.js
```
## Generator
There are thousands of AVPs, each with a unique avp-code and vendor-id. To aid readability and enhance the developer experience, we recommend defining them as constants in a separate file, for example, using `diam/const.js`.
You can either create the constant yourself or use the bin/dict_generator CLI tool to generate a full list of AVPs for you. Use the following command:
```bash
./bin/dict_generator -output example/diam/const.js
```
The CLI also supports generating additional AVPs that are not defined in the default list. Simply add the -dictionary flag to include the additional AVP definition:
```bash
./bin/dict_generator -output example/diam/const.js -dictionary dict/extra.xml
```

### Example
The following example demonstrates how to create a Diameter client in k6 with various configuration options.
```js
let client = diam.Client({
requestTimeout: "50ms",
enableWatchdog: false,
authApplicationId: [app.ChargingControl],
vendorSpecificApplicationId: [
{
authApplicationId: app.ChargingControl,
vendorId: vendor.TGPP,
}
],
capabilityExchange: {
vendorId: 35838,
},
})
```
