Travelokapay Load Test Participation Guide

Giving a little background on how we're going to proceed with travelokapay load test today, we're aiming to do load tests using a number of different users with several different scenarios. The scenarios included are:

Normal user {Traveloka homepage, Travelokapay homepage, Wallet activity page, Request top-up}
User who receives push-notification {Traveloka homepage}
User who only browses homepage {Traveloka homepage, Travelokapay homepage}
Normal browsing user {Traveloka homepage, Travelokapay homepage, Wallet activity page}

Some context you need to know before testing:

Travelokapay uses access token from traveloka as user identifier

The effect it has on our test:
We're doing load test only on travelokapay system, therefore to remove dependency from Traveloka and to reduce the risks it might imply on Traveloka side, we're going to inject access token manually instead of making it part of automatic test. And since access token has time to live (it can expire), injecting access token will be done before each test to make sure we always use fresh access token.

How to:

Initialize travelokapay load test:

Install locust by running pip install locustio or use sudo if neeeded, you can visit this page for more detail: https://docs.locust.io/en/latest/installation.html
Clone travelokapay-test repository from https://phabricator.noc.tvlk.cloud/diffusion/424/ or just git pull if you already clone this before to make sure we're all using the same version :)

Inject access token:

Get tvLifetime and tvSession

Debug Settings -> Traveloka Context (ANDROID)
Developer Settings (IOS)
Inspect element on travelokapay main page (WEB)

Get access token from Traveloka

POST /en-id/v2/user/idp/authorizeContext HTTP/1.1

"tvSession":"[your_tv_session]
},

}

Copy idToken value from no 2 response and set it as environment variable ACCESS_TOKEN

export ACCESS_TOKEN='[id_token]'

Increase open file limit

Please follow this guide on how to increase per-user limit https://easyengine.io/tutorials/linux/increase-open-files-limit/
Notes: you should only need to follow steps to edit /etc/security/limits.conf and to relogin after that
And to check if your limit has been updated:

Check Hard Limit in Linux
# ulimit -Hn
Check Soft Limit in Linux
# ulimit -Sn

Run locust as slave:

locust -f [file_path]/default-load-test.py --host=https://api-tpaypapi.stg.tvlk-pay.com --slave --master-host=10.10.45.23

for example, if you're currently on [your_path]/travelokapay-test/locust-file directory, you can just run

locust -f default-load-test.py --host=https://api-tpaypapi.stg.tvlk-pay.com --slave --master-host=10.10.45.23
