Marginal Relief Calculator Frontend performance tests

Performance test suite for the Marginal Relief Calculator Frontend, using performance-test-runner under the hood.

Running the tests

Prior to executing the tests ensure you have:

• Docker - to start mongo container (Note - there are other ways to run Docker on the command line so this command may be different)
• Installed/configured service manager

Run the following command to start the services locally:

docker run --rm -d --name mongo -d -p 27017:27017 mongo:4.0

sm2 --start MARGINAL_RELIEF_CALCULATOR_ALL -r --wait 100

Using the --wait 100 argument ensures a health check is run on all the services started as part of the profile. 100 refers to the given number of seconds to wait for services to pass health checks.

Logging

The template uses logback.xml to configure log levels. The default log level is WARN. This can be updated to use a lower level for example TRACE to view the requests sent and responses received during the test.

Smoke test

It might be useful to try the journey with one user to check that everything works fine before running the full performance test

sbt -Dperftest.runSmokeTest=true -DrunLocal=true gatling:test

Running the performance test

sbt -DrunLocal=true gatling:test

Run the example test against staging environment

Smoke test

sbt -Dperftest.runSmokeTest=true -DrunLocal=false gatling:test

Run the performance test

To run a full performance test against staging environment, implement a job builder and run the test only from Jenkins.
