K6 load tests for CompreFace services

Each folder inside tests folder contains a separate loading test. To run tests, first you need to build an image:

cd ./docker
docker build -t k6tests .

Then you can run all tests or define a list of tests (as TESTS env variable):

# run only face_verify and recognize tests
docker run \
    -e TESTS="face_verify;recognize" \ 
    -e HOSTNAME="http://myhost:8082" \
    -e INFLUXDB_HOSTNAME="http://myinfluxdbhost:8086"
    -e DB_CONNECTION_STRING="user=postgres password=postgres port=5432 dbname=frs host=mydbhost sslmode=disable" \
    k6tests

# run all tests
docker run \ 
    -e HOSTNAME="http://myhost:8082" \
    -e INFLUXDB_HOSTNAME="http://myinfluxdbhost:8086"
    -e DB_CONNECTION_STRING="user=postgres password=postgres port=5432 dbname=frs host=mydbhost sslmode=disable" \
    k6tests

Any test from tests folder follows those steps:

Apply db_init.sql to database
Run recognition test according to scenarios defined in the script
Apply db_truncate.sql to database

Run command details

docker run 
    --env IMAGES="./faces/FACE_512KB.jpg;./faces/FACE_1024KB.jpg"
    --env HOSTNAME="<host>"
    --env INFLUXDB_HOSTNAME="<influxdb_host>"
    --env DB_CONNECTION_STRING="user=postgres password=<password> port=5432 dbname=frs host=<db_host> sslmode=disable" 
    <image_id>

IMAGES list of images fot test (if images are needed for the test)
HOSTNAME hostname of test server
INFLUXDB_HOSTNAME hostname of influxdb
DB_CONNECTION_STRING DB connection string, template is "user=mydbuser password=mydbpass port=5432 dbname=mydbname host=mydbhost sslmode=disable"
