Migration Changes

All tests were updated to use the new @oclif/test v4 API:

Before (v2):
test
.stdout()
.nock('https://api.heroku.com', api => {
api.get('/oauth/authorizations/f6e8d969-129f-42d2-854b-c2eca9d5a42e')
.reply(200, authorization)
})
.command(['authorizations:info', 'f6e8d969-129f-42d2-854b-c2eca9d5a42e'])
.it('shows authorization info', ctx => {
expect(ctx.stdout).to.contain('[email protected]')
})

After (v4):
it('shows authorization info', async () => {
nock('https://api.heroku.com')
.get('/oauth/authorizations/f6e8d969-129f-42d2-854b-c2eca9d5a42e')
.reply(200, authorization)

const {stdout} = await runCommand(['authorizations:info', 'f6e8d969-129f-42d2-854b-c2eca9d5a42e'])

expect(stdout).to.contain('[email protected]')

})

Key Pattern Changes

1. API: Replaced chaining test API with runCommand() function
2. Async: Converted callback-style tests to async/await
3. Context: Destructured {stdout, stderr, error} from result instead of ctx parameter
4. Error Handling: Check error property in result object instead of .catch() chaining
5. Cleanup: Added afterEach(() => nock.cleanAll()) hooks
6. Nock Setup: Moved nock setup inside each test for better isolation

Testing

• ✅ All 25 migrated tests pass locally
• ✅ Tests pass in CI
• ✅ No regressions in other test suites
• ✅ Build passes

Notes

This PR establishes the migration patterns and approach that will be used across all subsequent PRs in the migration plan. The patterns
have been validated to work with core authentication functionality.
