Generally, tests should not call any external services like Telegram or Discourse. The calls to their APIs should be mocked with smth like GitHub - nock/nock: HTTP server mocking and expectations library for Node.js
I can try to mock telegram api, but what about arcanist suspended on those tests, when I only test welcome page and form
describe("Endpoints test", () => {
const app = express();
let server: Server<typeof IncomingMessage, typeof ServerResponse>;
before(() => {
server = app.listen(3000, () => {
console.log("Server is listening on port 3000");
});
app.use(express.json());
app.use(router);
});
it("request to home page should has status 200", async () => {
await request(app).get("/").expect(200);
});
it("should return a html form for GET request to /authorize", async () => {
await request(app)
.get("/authorize")
.expect("Content-Type", /html/)
.expect(200);
});
after((done) => {
server.close();
done();
});
});
in this test, you import the main.ts file, which in chained consequence imports also the bot.ts file, which immediately tries to create a telegram bot instance - on import time. It might be beneficial to instead wrap the telegram bot logic into a function and only call it when it’s necessary. You can do a sort-of singleton with smth like
let bot:Bot | null = null
function makeBot(){
return new Bot(...)
}
export function getBot(){
if(!bot){
bot = makeBot()
}
return bot;
}
(the details are of course missing from this example, but it should get my point across)
