[anshss]

Automated Tests: 18 node and 15 browser tests

CHANGES

• migrated complete repo to v7.0.4 from alpha
• spotted remaining migrations and did that
• added new node tests inside hacker-guides to nx
• fixed a few broken tests
• added apps dir for running all scripts in the browser
• added playwright to automate browser tests

PLAYWRIGHT-TESTS

• includes apps dir containing a NextJS app hooked to example scripts of node tests
• changes on the utils files and somewhere in the index (where env are consumed) due to differences in env environments to make the scripts support both node and browser environment
• includes playwright tests for testing against changes on UI

Wrapped Keys test usually fails at times

NODE TESTS

BROWSER TESTS

COMMENTS

• 3 examples include file system handling through fs which cannot be made to run in a browser and only contains node tests

  • encrypt-file
  • encrypt-large-file
  • solana-openai

• examples are in the browser and need to be translated to node test so they can be run and tested in both environments

  • siws-accs
  • siws-authentication
  • siws-encryption
  • siws-session-sigs
  • custom-auth
  • lit-relayer/mintPKPThroughRelayer

• btc-trigger test couldn't be made to run on its own in any environment as it requires fetching utxo in a newly created lit-btc wallet to generate a txn with it
