Testing the load on LNbits core. This does not include extension functionality.

• increase Rate Limiter in settings to 100000

Different test scenarios that cover the usual interaction of the users with the application

This is a regular user that sends and receive a moderate amount of payments (around 20 during the tests). The test starts a number of XXX users in parallel and analyzes how the system behaves (XXX can vary from 10 to 10 000). There is ramp-up period (users login at one second one after another). There also exists a think time (usually 1 sec) between different users actions.

Steps (set-up phase):

• Register User
• Get User details (as done from the UI)
• Logout User
• Top-up wallet of freshly registered users

Steps (test phase):

• Login User
• Get User details
• Create New Wallet
• Repeat XXX times:
  • [user] Get Enabled Extensions
  • [user] Get BTC Price
  • [user] Create Invoice
  • [user] Pay Invoice
  • [user] Search Payments (in one wallet)
  • [user] Search Payments (across all wallets - Payments page)
  • [user] Get All Extensions
• Logout

This user has a many wallets and many payments in each wallet. The parallel requests do not simulate real user actions, but are more similar to API calls from different systems.

Steps (set-up phase):

• the user is already created, it has a large number of wallets and of payments (a loadtest DB is maintained for this)

Steps (test phase):

• Login User
• Get User details
• Create New Wallet
