🛠️ Repo: Improving test isolation in Workflow

[matiassimon]

Summary:

The current workflow runs all tests together in a single job, causing two main issues:

1. Tracking Difficulty:

   • It's challenging to distinguish which examples are functioning correctly and which aren't.

2. Dependency Interference:

   • Shared system dependencies might lead to misleading test results; an example might pass due to a dependency installed by a different example.

Proposed Solutions:

1. Matrix Strategy:

   • Consider replacing Lerna with a matrix strategy in the workflow, iterating over each package's folder independently.

   strategy:
     matrix:
       folder:
         - example1
         - example2
         - example3
       node-version:
         - 16
         - 18

2. Separate Repositories:

   • Alternatively, use individual repositories for each example, each with its own workflows. Add them as submodules to a main repository.

Oh! Sorry for taking so long to get to this @matiassimon! We'd just started working on Mocha in January (mochajs/mocha#5027) and have mostly been focusing on the main repo. But this examples repo needs love too - and we should have responded sooner. Sorry!

+1 to this issue as described. It's annoying having them run in fail-fast series and interfering with each other.
