Testing Stratus

Local

Upgrade

Test catalog consistency when upgrading from one version of Stratus to another.

cd ./standalone/upgrade
./test_upgrade.sh $OLD_VER $NEW_VER

Ad-hoc

Prerequesites:

1. Load data - na_roads

  • na_roads Load na_roads into
./standalone/na_roads_postgis.sh # if prompted, it is for a password. Enter 'docker' up to 3 times.

./standalone/loadPgData.sh

2. Load data - geotiff

Assumes acme workspace is created already. If not, then

./standalone/createWorkspace.sh

then

./standalone/loadGeotiff.sh

3. Load data - Sierpinski carpet

Assumes acme workspace is created already. If not, then

./standalone/createWorkspace.sh

then

./standalone/loadPgFractalData.sh

4. Load simulated points data

First, create the points in your database

python ./python/generate_points.py --load-pg --workspaces 100 --layers 10 --points 1000 --db-host localhost --db-port 5432 --db-username docker --db-password docker

Next, create the geoserver workspaces, datastores, and featuretypes

python ./python/generate_points.py --load-gs --workspaces 100 --layers 10 --points 1000 --geoserver-host localhost --geoserver-port 8080 --db-host localhost --db-port 5432 --db-username docker --db-password docker

Jmeter

Test simulated points data

Locust

See locust/README.md and locust/Building_locust.md on locust install

  • Load test Start locust. In this case, it's a wms png test but you could configure locust to run other tests under the varying load as well.
locust -f code/wms_tester.py -n1000 -c1 --host=localhost:8080

You can start/stop loads from the UI: http://localhost:8089. Of course, it's more helpful to run the load test on a remotely deployed instance but localhost:8080 is provided above for a simple start.

  • Simulate scale up and scale down of users via csv file of load over time ** Edit a csv file (usage_load.csv is given as a starter) and set the prescribed load
vi usage_load.csv

** Start locust as above. Now visit http://localhost:8089 to see the locust web UI. The simulation will utilize the rest interface to start and stop specific tests based on the usage_load.csv ** Run the simulated load tests

simulate_variable_usage.py

Test latencies for catalog updates

locust/post_latency.py e.g.,

python3 post_latency.py $STRATUS_HOST  \
    --database-host $DB_HOST \
    --database-port $DB_PORT \
    --database-name $DB_NAME \
    --database-user $DB_USER \
    --database-password $DB_PASSWORD \
    --test-count 2 --delay 0.01 --max-fails 10
