Happy path

How it is used

Example sentences

  1. The demo covers the happy path, but what happens if the card is declined?

  2. We only tested the happy path, which is why the empty-cart bug reached production.

  • edge caseAn unusual situation at the limits of what a program expects, such as an empty list, a very long name or a date like 29 February.
  • test caseOne specific situation you check, with set inputs, steps and an expected result, for example 'logging in with a wrong password shows an error'.
  • end-to-end testA test that runs a complete user journey through the real system, for example opening the site, logging in and placing an order, to check that everything works together.
  • error handlingCode that deals with things going wrong, such as a failed request or bad input, so the program can recover, retry or show a clear message instead of crashing.
