Refresh auth token

[Mathdon]

What would you suggest to handle re-freshing an auth token when testing API's that need this?

I use the before hook to make a request to get the token and then use that in the requests.

The problem I have is if trying to run a test for longer than an hour the token expires and I get 403's back from the API.

What would be the best way to refresh the token?

If the same token is shared by all VUs, you could use a beforeScenario hook and grab a new token when the current one expires.

Thank's for the reply @hassy I'll give that a go

Hi @hassy

I have make a little script that works for refreshing a token.

it works with these plugins

  plugins:
    expect: {}
    metrics-by-endpoint:
      useOnlyRequestNames: true
    publish-metrics:

But when adding these plugins

   plugins:
    apdex:
      threshold: 2000
    ensure:
      thresholds:
        - "http.response_time.p99": 2000
        - "vusers.failed": 1
        - "apdex.frustrated": 99

It throws an error:

⠋ /node_modules/artillery-plugin-apdex/index.js:42
    script.config.processor.apdexAfterResponse = apdexAfterResponse;
                                               ^

TypeError: Cannot create property 'apdexAfterResponse' on string '../plugins/manage_auth_token.js'

    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
    at async Launcher.run (/node_modules/artillery/lib/launch-platform.js:394:5)

And:

⠋ /node_modules/artillery-plugin-ensure/index.js:38
    const checks = this.script.config.ensure || this.script.plugins.ensure;
                                                                    ^

TypeError: Cannot read properties of undefined (reading 'ensure')
    at new EnsurePlugin (/node_modules/artillery-plugin-ensure/index.js:38:69)
    at Launcher.initPlugins (/node_modules/artillery/lib/launch-platform.js:200:31)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
    at async Launcher.run (node_modules/artillery/lib/launch-platform.js:394:5)

I added the script using the processor

processor: "../plugins/manage_auth_token.js"

And then it is called in the beforeRequest hook (get the same error in the beforeScenario hook)

Any ideas on this?

Hi @Mathdon 👋🏻,

I believe you are running into 2 different issues:

• For the ensure plugin, by reading the error I can see that you are either using the old ensure plugin and installing it separately (ensure is now natively supported and the old one is deprecated), or you are using an old version of Artillery.

• As for the apdex plugin, this issue was recently resolved and published in the canary version 2.0.0-37-9c51118. It will also be released in the next version of Artillery - v2.0.0-38.

You should be able to resolve both these issues by installing the mentioned canary version (for now) and making sure you do not have any other versions of ensure plugin installed.

Hope that helps! Let us know if you need help with anything else. 🚀

Hi @InesNi

Thank you for the reply, using the version you mentioned has fixed the issue :)

There's an example for this scenario here now: https://github.com/artilleryio/artillery/tree/main/examples/refresh-auth-token
