Migration Changes

Before (v2) - Command tests:

test
  .nock('https://api.heroku.com:443', api => {
    api
      .get('/spaces/my-space/dynos')
      .reply(200, spaceDynos)
  })
  .stdout()
  .command(['spaces:ps', '--space', 'my-space'])
  .it('shows space dynos', ctx => {
    expect(ctx.stdout).to.equal('...')
  })

After (v4) - Command tests:

it('shows space dynos', async function () {
  nock('https://api.heroku.com:443')
    .get('/spaces/my-space/dynos')
    .reply(200, spaceDynos)
    .get('/spaces/my-space')
    .reply(200, {shield: false})

  const {stdout} = await runCommand(['spaces:ps', '--space', 'my-space'])

  expect(stdout).to.equal('...')
})

Before (v2) - Tests with stubs:

test
  .stub(hux, 'wait', () => Promise.resolve())
  .nock('https://api.heroku.com', api => {
    api.get(`/apps/${APP_NAME}/releases`).reply(200, [CURRENT])
  })
  .command(['ps:wait', '--app', APP_NAME])
  .it('waits for all dynos to be on latest release', ctx => {
    expect(ctx.stderr).to.contain('Waiting for every dyno')
  })

After (v4) - Tests with stubs:

it('waits for all dynos to be on latest release', async function () {
  sinon.stub(hux, 'wait').resolves()

  nock(API_HOST)
    .get(`/apps/${APP_NAME}/releases`)
    .reply(200, [CURRENT])
    .get(`/apps/${APP_NAME}/dynos`)
    .reply(200, [...])

  const {stderr} = await runCommand(['ps:wait', '--app', APP_NAME])

  expect(stderr).to.contain('Waiting for every dyno to be running v23... 2 / 2, done')
})

Before (v2) - Utility/library tests:

describe('webhooks type', function () {
  test
    .stdout()
    .do(function () {
      const webhookInfo = webhookObject.webhookType({pipeline: 'randomPipeline', app: ''})
      expect(webhookInfo).to.deep.equal({path: '/pipelines/randomPipeline', display: 'randomPipeline'})
    })
    .it('returns correct pipeline path and display info')
})

After (v4) - Utility/library tests:

describe('webhooks type', function () {
  it('returns correct pipeline path and display info', function () {
    const webhookInfo = webhookObject.webhookType({pipeline: 'randomPipeline', app: ''})
    expect(webhookInfo).to.deep.equal({path: '/pipelines/randomPipeline', display: 'randomPipeline'})
  })
})

Key Pattern Changes

1. Standard runCommand(): Used @oclif/test v4's runCommand() for all command tests
2. Async/await: Converted all tests to async/await functions
3. Destructuring: Used {stdout, stderr, error} from runCommand results
4. Error handling: Used {error} destructuring for error assertions instead of try/catch or .catch() chains
5. Imports: Changed expect import from '@oclif/test' to 'chai'
6. Stub handling: Moved sinon stubs inside test functions with sinon.stub() and proper sinon.restore() in afterEach
7. Nock cleanup: Added afterEach(() => nock.cleanAll()) hooks for proper test isolation
8. Helper functions: Created helper functions like dynoTestSetup() in ps/enable to reduce test duplication
9. Integration tests: Converted complex chaining tests with custom setup functions to standard async/await patterns
10. Utility tests: Migrated non-command tests (webhooks, keyValueParser, paginator) to standard mocha format without @oclif/test dependencies
11. Uncommented tests: The lib/webhooks/base tests were previously commented out - uncommented and migrated them to v4
12. Skip file cleanup: All .skip files properly deleted and tracked in git commits

Testing

• ✅ All 68 migrated tests pass with npx mocha
• ✅ 68 passing, 3 pending (skipped integration tests)
• ✅ No test regressions
• ✅ Proper test isolation with cleanup hooks

Notes

This PR completes the final batch of remaining test files for the @oclif/test v4 migration. The files covered a diverse range of testing scenarios:

• Command tests: Standard pattern using runCommand() with nock for API mocking
• Tests with stubs: Used sinon.stub() for mocking dependencies like hux.wait
• Utility tests: Converted to standard mocha tests without @oclif/test chaining
• Library tests: The webhooks/base tests were previously commented out and have been uncommented and migrated
• Integration tests: Complex run command tests with process.argv manipulation and rendezvous connection mocking

Key learnings:

• The ps/wait test required using hux.wait from @heroku/heroku-cli-util instead of ux.wait
• Helper functions are valuable for reducing duplication in tests with similar setup (e.g., dynoTestSetup)
• Integration tests benefit from beforeEach/afterEach hooks to save and restore process.argv
