Preformance testing with K6 and Keycloak

• Set the server, realm, grantType, clientId, clientSecret variables in the collection
• Create a token variable with no data to the collection
• Add the following script into your collections Pre-request scripts:

if (pm.variables.get("token") === undefined) {
    var url = `${pm.variables.get("server")}/auth/realms/${pm.variables.get("realm")}/protocol/openid-connect/token`;

    var payload = {
      grant_type: pm.variables.get("grantType"),
      client_id: pm.variables.get("clientId"),
      client_secret: pm.variables.get("clientSecret")
    };

    var params = {
      headers: {
        "Content-Type": "application/x-www-form-urlencoded"
      }
    };

    var kcResult = http.post(url, payload, params);
    var jsonResult = JSON.parse(kcResult.body);
    pm.environment.set('token', jsonResult.access_token);
}

• Add authentication "Bearer token" to the collection and set the token to {{token}}
• Export collection as collection.json
• Start runstest.bat to begin the performance test
