Prep for running load test - Connect to DB and get auth cookie:

To kick off the load tests you will need to do the following:

1. Port forward to Access the DEV RDS Database
2. Go to Manage a workforce Dev web application and grab the connection.sid cookie's value:

• Go here in Google Chrome: https://workforce-management-dev.hmpps.service.justice.gov.uk
• Log in
• Right-click browser > Inspect
• Go to Application tab > Storage in left nav > Expand Cookies
• Find the connect.sid cookie in the list and copy its' value from the Value column
• Copy the value for later step

Run load tests in Intellij:

1. Open repo in IntelliJ
2. Go to AllocateCaseSimulation.kt and set the concurrent user and during functions to ensure you are running the correct load against the APIs.

• For example 1 user for 1 second would be users.injectClosed(constantConcurrentUsers(1).during(1))

3. Right-click on Engine.kt class > Run Engine
4. This will fail as missing env vars
5. Add missing env vars to Engine configuration:

• Click on the Engine configuration that now exists next to the Run button on the top panel in Intellij
• Click on Edit Configurations
• Paste this into the VM options box (and swap out variables below for real values - see Prep for running load test for how to get the value for auth_cookie_value and the rest our k8s secrets): -DconnectSidCookieValue=<auth_cookie_value> -Ddb_name=<db_name_value> -Ddb_password=<db_password_value>

Run load tests in Terminal:

1. Change directory in a terminal and navigate to this repo's root folder
2. Run this command (and swap out variables below for real values - see Prep for running load test for how to get the value for auth_cookie_value and the rest our k8s secrets):

./gradlew gatlingRun-uk.gov.justice.digital.hmpps.maw.gatling.simulations.AllocateCaseSimulation -DconnectSidCookieValue=<auth_cookie_value> -Ddb_name=<db_name_value> -Ddb_password=<db_password_value>
