locust-wms-load-test's Issues

Issues using locust-wms-load-test

Hello,
I tried to run the WMS test... at first it looked promising.

However I found the following problems:

  • locust-wms seems to store it's setting somewhere in the browser (cookies or something)... and once you enter the initial parameters, you can not change them anymore (even closing the browser does not work). It accepts the info but the tests do not start. I had limited success with it by clearing browser data - but event that does not work always.
  • LOG_VERBOSE=1 does not seem to do anything...
  • it seems that the test is requesting GetCapabilities as html instead of xml
# docker run --rm -i -t -p 8089:8089 \
       --env LOG_VERBOSE=1 \

GetCapabilities parse error with OWS

Looking to adopt locust and replace Jmeter as load-testing framework for OWS

Ran this container with:

docker run --rm -i -t -p 8089:8089        eduardrosert/locust-wms-test        locust -f /app/wms-load-test/locustfile.py               --host=https://ows.dea.ga.gov.au//wms

Ran into the following errors:

File "/usr/local/lib/python3.6/site-packages/locust/core.py", line 374, in run
    self.execute_next_task()
  File "/usr/local/lib/python3.6/site-packages/locust/core.py", line 400, in execute_next_task

    self.allLayers[wmsversion] = getAllLayers(capabilities=capabilities, wmsversion=wmsversion)
  File "/app/wms-load-test/locustfile.py", line 271, in getAllLayers
    root = capabilities[rootNodeName]["Capability"]["Layer"]

Need to make width and height of boundingbox customizable for wms

https://ows.dev.dea.ga.gov.au/?request=GetMap&crs=EPSG%3A4326&layers=ga_ls7e_ard_3&width=1200&height=600&format=image%2Fpng&bbox=-14%2C-1%2C166%2C89&service=wms&version=1.3.0&styles=false_colour&time=2006-12-21

is XML file does not appear to have any style information associated with it. The document tree is shown below.

k8s deployment file incorrect command

Problem

the current example https://github.com/EduardRosert/locust-wms-load-test/blob/master/k8s-locust-wms-test.yaml#L39-L40 returns command /bin/bash not found error

tried

      command: ["locust"]
      args: ["-f /app/wms-load-test/locustfile.py"]

the pod doesn't start and errors

the pod started correctly when both command and args were commented out.

correct config (final solution)

        command: ["locust", "-f", "/app/wms-load-test/locustfile.py", "--host=$(WMS_SERVICE_URL)"]
        # args: [ "-f /app/wms-load-test/locustfile.py"]

note, without $() around WMS_SERVICE_URL the value is taken as `$WMS_SERVICE_URL.
