Problem

Solution

## Problem
The `AppBuilder Walkthrough` test was previously skipped because it is
flaky and would some friction when merging in PRs to the
`feature/v2-to-v3-migration` branch

## Solution
Unskip the `AppBuilder Walkthrough` test as we prepare to merge the
`feature/v2-to-v3-migration` branch into `main`

The E2E and integration tests seem to be running on this PR because the test files were changed:

  • packages/core/src/testE2E/codecatalyst/client.test.ts
  • packages/core/src/testInteg/sam.test.ts

Based on the latest commits to master branch: https://github.com/aws/aws-toolkit-vscode/commits/master/, the same E2E and integration tests are also failing. Here are some examples from existing master branch:

what's up with the failures?

To my knowledge, the E2E/Integration tests have always failed. They will run after every commit into main. By default, they are not run before a PR is merges, but can be if a user comments /runIntegrationTests on the PR.

Based on the CI on the latest commit to main, all E2E/Integration tests are still failing. Even when browsing through all the commits to main in August for example, all E2E/Integration still failed.

At this point, I'm not sure if anyone even checks them or we can reliably trust the results of them without a further deep dive.

In regards to why the E2E/Integration tests are running on this PR, it looks like they are also automatically run if the test files were edited. In this case, I migrated these files:

  • packages/core/src/testE2E/codecatalyst/client.test.ts
  • packages/core/src/testInteg/sam.test.ts
