Um, my name is Courtney, and today I'm going to talk about testing in production with JavaScript.

What, Come two years come put up its and thanks for coming to my talk.

I'm from Spain, and I'm currently working a Bristol.

Started working on autonomous indoor navigation.

Baker's fronts on, then got back to the close pay for years working at I start back, called me that just got a quiet about being worse.

So I could just do with my team on now currently working at Dyson.

So I always like the star that talks with a quick pour to know how the audience is doing on this topic.

Um, I want to know how many of you know what Javascript ms.

Um, are here for the city, the food, the party, and just a bit of javascript.

About the test empire made or any other way of classifying the different testing levels.

Um, who has a production environment again?

Who is not afraid of testing in production.

So, um, are you testing your services in production?

So they still what's this talk about the stock is about.

I'm gonna try to answer some frequently asked questions about testing on your production were close.

I'm not going to deep inside any JavaScript kill on its whole base.

From the experience I gained working, I dance a Dyson.

I've been working a Dyson for almost two years now.

Um, and there has been great and we have learned a lot about testing in production.

So this is a quick summary of what I'm gonna I'm going to answer.

Why do you need testing intestine production with the white tested level?

J s work help with this, um, helped a boy disrupting the real uses.

Because if you're testing in production, you're gonna be part off your users.

You're gonna be using protection systems.

How to keep, um, how to keep your test out of the statistics reports out of metrics.

So when you report your to your money Oh, too high, get the business.

Well, that's a good question, but I hope most of you can answer that.

When you deploy your application, I could be an application in the surveys.

Whatever thing you deploy to production and has s o the public has access to is, um, you need to guarantee its continues to work over the days and over the hours.

The unit ties it past the service level, tears or whatever.

And then I deploy and I don't care about my service.

The service is running in production, and if something happens to it, you want to get notified?

No, but they users, but by some automated system so they d about.

This is to have some kindof testing tool that runs on a schedule basis.

So it's testing your service like it was a real user.

Andi, if something happened so the test fail, it means that a real use it wasn't able to do one off.

The actions you have defined for your production service's on.

So here's a quick simple in my same dumb.

So imagine you have a London function that returns the current date right on.

Dhe doesn't cut it for the year 2038 problem, which is when you're storing your date in a sign it 32 bits Bible do run out off space to store the date, and then you overflow right on the 16th off generate 2038.

You right, you need test for you issue, which, on a date, if you query for the date again, he should return a different number.

Do you deploy it on after a handful of years?

It's because it has dynamic being put out, but it depends on own on the current time, on how the users are interactive winter service or what the service is returning dynamically but going to a more Rio situation.

Imagine one of your state full service is so it's a service that store some estate on your users on your data vase or on the state of your system.

Then suddenly by a buck or whatever becomes inconsistent, and then it starts failing for all the customers.

Then, when you will have it's a heart off customers chasing you, angry customers saying this is not working.
