examples/general/stats.ts (1)
87-92: Consider awaiting function calls or using an async IIFE.The example functions are called without
await, meaning errors won't be handled at the top level and execution order isn't guaranteed. For a cleaner example:Suggested fix
-testGetStats() -testGetStatsWithFilters() -testGetStatsByDomains() -testGetStatsByCategories() -testGetStatsByEmailServiceProviders() -testGetStatsByDate() +(async () => { + await testGetStats() + await testGetStatsWithFilters() + await testGetStatsByDomains() + await testGetStatsByCategories() + await testGetStatsByEmailServiceProviders() + await testGetStatsByDate() +})()🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@examples/general/stats.ts` around lines 87 - 92, The example calls to testGetStats, testGetStatsWithFilters, testGetStatsByDomains, testGetStatsByCategories, testGetStatsByEmailServiceProviders, and testGetStatsByDate are invoked without awaiting, so wrap these calls in an async IIFE or await them from an async function and handle errors; update the example to either (1) make the top-level module run an immediately-invoked async function that sequentially awaits each of the listed functions (testGetStats, testGetStatsWithFilters, testGetStatsByDomains, testGetStatsByCategories, testGetStatsByEmailServiceProviders, testGetStatsByDate) with try/catch around the sequence to surface errors, or (2) export/use an async main() that awaits each function and catches/logs errors before exiting.src/__tests__/lib/api/resources/Stats.test.ts (1)
70-91: Consider moving initialization tests afterbeforeAll.The
describe("class Stats(): ")block (lines 70-80) appears beforebeforeAll(lines 82-91). While this works because Jest hoistsbeforeAll, it's unconventional and could confuse readers. Consider movingbeforeAllto the top of the outerdescribeblock for clarity.🤖 Prompt for AI Agents

75-94: Consider adding a guard for unknown group keys.While
groupedStatsis private and only called with valid keys, adding a guard would make the code more defensive against future changes:Optional defensive check
private async groupedStats( group: string, params: StatsFilterParams ): Promise<SendingStatGroup[]> { const url = `${this.statsURL}/${group}`; const groupKey = GROUP_KEYS[group]; + + if (!groupKey) { + throw new Error(`Unknown stats group: ${group}`); + } const response = await this.client.get<🤖 Prompt for AI Agents

Inline comments:
In `@examples/general/stats.ts`:
- Around line 4-5: The example defines ACCOUNT_ID as a string placeholder but
MailtrapClient expects a numeric accountId; change the placeholder to a numeric
literal (e.g., ACCOUNT_ID = 123456) or update usage to coerce/parse it to a
number before passing to MailtrapClient (reference ACCOUNT_ID and the
MailtrapClient constructor/accountId parameter) so the example shows a number
type rather than a string.

Nitpick comments:
In `@examples/general/stats.ts`:
- Around line 87-92: The example calls to testGetStats, testGetStatsWithFilters,
testGetStatsByDomains, testGetStatsByCategories,
testGetStatsByEmailServiceProviders, and testGetStatsByDate are invoked without
awaiting, so wrap these calls in an async IIFE or await them from an async
function and handle errors; update the example to either (1) make the top-level
module run an immediately-invoked async function that sequentially awaits each
of the listed functions (testGetStats, testGetStatsWithFilters,
testGetStatsByDomains, testGetStatsByCategories,
testGetStatsByEmailServiceProviders, testGetStatsByDate) with try/catch around
the sequence to surface errors, or (2) export/use an async main() that awaits
each function and catches/logs errors before exiting.
In `@src/__tests__/lib/api/resources/Stats.test.ts`:
- Around line 70-91: Move the test setup so initialization runs before the spec
declarations: relocate the beforeAll block (which initializes
axios.interceptors.response.use, handleSendingError, and creates the
AxiosMockAdapter mock) to the top of the outer describe that contains the "class
Stats(): " tests so that beforeAll executes visually before the describe("class
Stats(): ") block and the statsAPI initialization tests
(expect(...).toHaveProperty(...)) appear after the test setup; keep references
to axios.interceptors.response.use, handleSendingError, AxiosMockAdapter, mock,
and statsAPI intact.
In `@src/lib/api/resources/Stats.ts`:
- Around line 75-94: Add a defensive guard in groupedStats: after computing
const groupKey = GROUP_KEYS[group], verify groupKey is defined and handle the
unknown case (e.g., throw a clear Error mentioning the invalid group or return
an empty array) before using it to build the response; update groupedStats (and
any callers if needed) so the function fails fast with a descriptive message
referencing groupedStats and GROUP_KEYS when an invalid group is supplied.
