# scalability-simulation-generator

Generates simulations from APM parser output

## How to use

Build project

```
yarn install && yarn run build
```

Put json files from APM parser (each json file should contain requests for a single journey) into some directory, e.g. `sample`

Run script:

```
node scripts/generate_simulations.js --dir ./sample --packageName org.kibanaLoadTest --url "http://localhost:5620"
```

Check `output` directory for .scala files.

Generated simulation example:

```
package org.kibanaLoadTest

import scala.concurrent.duration._

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import io.gatling.jdbc.Predef._
