Hapi hemera testsuite Timeout error

[vforv]

When I try use hemera with server.inject it doesn't work I am getting Timeout error, it looks like add is never called by act....

here is example:

L.test('Create general info', (done) => {
        const nats = new Nats()
        const hemera = new Hemera(nats, {
            logLevel: 'info'
        });

        hemera.ready(() => {
            hemera.add({
                topic: 'kycc',
                individual: false,
                create: 'general-info'
            }, (msg: any, done: any) => {
                console.log("TEST")
                done(null, "mock")
            })
        });

        const options = {
            method: "POST",
            url: "/v1/route",
            payload: {
            }
        };
        server.inject(options, (response: any) => {
            expect(JSON.parse(response.payload).statusCode).to.equal(200);
            done();
        });
    });

Act call will be called inside /v1/route route... What can be problem?

[StarpTech]

Hi, @vforv please post the full code. Do you use Hapi? Please also report all versions.

[vforv]

It's a little bit complex but I will put main part:

This function is hit when route /v1/route is called:

createGeneralInformation(req: HapiRequest, reply: Hapi.ReplyNoContinue) {

        req.hemera
            .act(
            {
                topic: 'kycc',
                individual: false,
                create: 'general-info'
            },
            (err: Error, result: any) => {
                if (err) {
                    return reply(Boom.boomify(err, { statusCode: 500 }));
                }
                return reply({data: result})
            })
    }

I checked route is 100% called bacuse when I print err inside this function it log this message:

{ TimeoutError: Timeout at timeoutHandler (/node_modules/hapi-hemera/node_modules/nats-hemera/lib/index.js:1380:21) at Timeout._onTimeout (/node_modules/nats/lib/nats.js:1233:9) at ontimeout (timers.js:365:14) at tryOnTimeout (timers.js:237:5) at Timer.listOnTimeout (timers.js:207:5) message: 'Timeout', app: 'test', isServer: false, pattern: 'create:general-info,individual:false,topic:kycc' }

I am using this versions:

"hapi": "^16.5.0",
"hapi-hemera": "^1.0.x",
"nats-hemera": "^3.1.6",
"hemera-testsuite": "^2.0.5",

I saw there is new version of hapi-hemera but I cannot run code if I use 2.0.x version...

The ready callback happens inside a new tick. You can't act when hemera is not ready.

[vforv]

Same happens if I put server.inject inside ready callback like this:

L.test('Create general info', (done) => {
        const nats = new Nats()
        const hemera = new Hemera(nats, {
            logLevel: 'info'
        });

        hemera.ready(() => {
            hemera.add({
                topic: 'kycc',
                individual: false,
                create: 'general-info'
            }, (msg: any, done: any) => {
                console.log("TEST")
                done(null, "mock")
            })

         const options = {
            method: "POST",
            url: "/v1/route",
            payload: {
            }
        };
        server.inject(options, (response: any) => {
            expect(JSON.parse(response.payload).statusCode).to.equal(200);
            done();
        });

        });
    });

Your example is too complex and I don't see the hapi handler.

[vforv]

Here is that part:

register: this.server.route({
                    method: 'POST',
                    path: '/v1/route',
                    handler: this.nonIndividualLogic.createGeneralInformation,
                    config: {
                        auth: 'amerbank-user',
                        description: 'Create general information for non-individuals',
                        validate: {
                            payload: createGeneralInfoValidator,
                            headers: {
                                Authorization: Joi.string()
                            },
                            options: {
                                allowUnknown: true
                            }
                        }
                    }
                })

Everything works well when run service and call routes with other servers... But only I have a problem with testing...

[StarpTech]

Which (Hapi, hemera-hapi, nats-hemera) versions do you use ?

[StarpTech]

Forget it, I see it.

[StarpTech]

Could you simplify your example so that you only use act and add with hapi ? Without auth, validation etc..

[vforv]

What did you mean? Everything works well when I run all services and call route... But the problem when I run it with the test so I think there is some problem with hemera-testsuite?

[StarpTech]

If you could provide an example which can I run immediately it would help me a lot.

[StarpTech]

You could create a repo with the issue. That would be nice.

[vforv]

Here: https://github.com/vforv/hemera-testsuite-error

If you run node index.js and visit route locahost:3000/v1/route add and act will work fine

But if you run node test.js it will return timeout error and add will never run...

[StarpTech]

I know what's the problem is. You pass a connection string to hapi-hemera instead the nats emulation. It's reasonable that hemera try to connect with a real NATS server.

[StarpTech]

You also use an old version and I don't support Hapi < 16. I recommend you to do full integration test or upgrade to Hapi 17.

[StarpTech]

Currently, we don't support to pass the nats emulation object to plugins like hapi-hemera it will create a new connection to the server that's why you get a timeout.

[vforv]

We don't need full integration tests for api gateway... So currently there is no way to emulate nats inside hapi-hemera?

[StarpTech]

It's no hassle to use a real nats server to test your application. We already provide great tooling with hemera-testsuite. If you need in-memory test you can create a PR in hapi-hemera.

[vforv]

Aha, I see now it is changed? We don't need any more to have gnatsd running in localhost to run tests? Is it possible to use remote nats server?

[StarpTech]

Yes, we provide two ways to create a test environment. Look in the readme https://github.com/hemerajs/hemera-testsuite

Is it possible to use remote nats server?

You can connect to any NATS Server but hemera-testsuite is responsible to bootstrap a server on localhost.

[vforv]

So I still need to have installed and running nats daemon in localhost?

[StarpTech]

If you only want to test Hemera you have two options:

• Testing with real NATS Server
• Use in-memory abstraction (Don't require a real nats server) but it doesn't support all features of nats.

The support of both solutions for the Hemera plugins is another question. Please create an issue in the specific repository.
