[Sangeetha-Bheeman]

Describe the Housekeeping
As developers we need to upgrade Quanthub to Vue 3 as Vue 2 is out of support in December 2023. As part of this we need to replace Jest with Vitest.

Acceptance criteria
To be considered successful the solution must allow:

• Replace Jest with Vitest.
• The application to continue to work as expected with no loss of service for users

[Sangeetha-Bheeman]

Tasks:

• Install vitest
• Add vitest related config to vite.config
• Remove jest config and its dependencies
  • Jest has globals enabled by default, so describe, expect, test etc are available from the global scope. Vitest does not. So this needs to be handled, either enabling globals via the globals config setting or update code to use imports from the vitest module instead.
• Modify the test files to remove jest dependencies and replace it with vitest utility functions using vi helper.
• Testing:
  • Run and pass all the unit tests and e2e tests.
  • Run the application to upload a quantfile successfully and test the qc data is exported to Sequencescape.
  • Test printing works as expected.
