#flakytests — Public Fediverse posts

RE: https://mastodon.social/@testlens/116250988040244817

I very much enjoy the work on TestLens with @britter and @marcphilipp. So many ideas to tackle the pain many developers in our space feel every day. The next features are already in the making. And we get a bunch of very good feedback from our early beta users. Let me know, if you want to join in!

Thanks for having me at CloudLand 2025 yesterday - it's been a pleasure to be there, even with the advanced temperatures 🥵 . However for those occasions I can highly recommend the water roller coaster 💦

Florian Heubeck et al. thanks again for raising the opportunity to me!

After a long train trip I've finally arrived in Brno yesterday. Now I'm well rested and ready to attend this year's devconf.cz instance 🥳

I'll be attending devconf.cz till Saturday - ping me if you want to meet up!

And I'll talk about zapping flakes once again - pew pew 🔫 - session is Saturday 12:30

#devtalks #romania #flakytests

excited to talk about the topic that is dearest to my heart again: how to zap flaky tests in our code base. this is so important for the @kubevirt project

The awesome team at @gradle.com have taken my blog posts and Opinions about Flaky Tests and put them all together in a very wonderful white paper!

Whether you care about flaky tests or think you don't have to worry about them, there's something in here for you.

Are #FlakyTests disrupting your CI/CD pipeline & draining Developer Productivity?

Trisha Gee dives deep into the hidden impact of these non-deterministic tests.

Learn why ignoring them is a costly mistake for code quality, build times & your team's sanity.

Do you remember my talk at FOSDEM about flaky tests last year? 🤔 I’ll be talking about zapping your flaky tests with a laser gun tomorrow! Pew-pew… 🔫
No, seriously - I’ll talk about an approach to detect flaky tests with AI.
Come visit the Testing and Continuous Delivery DevRoom in UD6.215 on Saturday! My talk starts at 13:15 if you’re interested. “https://fosdem.org/2025/schedule/event/fosdem-2025-5200-zap-the-flakes-leveraging-ai-to-combat-flaky-tests-with-cannier/”

I bumped into this again on an asymc (frontend) test suite and I have bad news for everyone:

If you don't run your tests in (pseudo)random order, you have no clue if your test suite is stable or not. No, none, nil, even if you've never seen it fail.

Do run your tests in random sequence. Always.

To all people from #stackconf that attended my talk about #flakytests today, I was promising to publish links to the slides, here they are:

Happy rest of the conference, and safe travels back.

And fix your flaky tests 😜

So happy to be invited as a speaker at #stackconf #berlin this year! Lots of socializing going on here - met a number of very nice people already.

Gentle reminder that my talk will happen tomorrow at 11:15AM, it is about minimizing impact of #flakytests.

Today I’m going to delete some flaky tests.

Flaky tests are worse than no tests.

#devLife #flakyTests

Looking forward to speaking at #stackconf 2024 in Berlin!

My talk will be about #FlakyTests , I'll try to bring some light into why we need to reduce the impact and share some findings about how to distinguish them. I'd also like to have a discussion in the Q&A section about your experience with this topic, so we can learn together from this.

The video for my talk from Sunday is available from the FOSDEM website now.There are two formats available, so I'm not linking it directly.

Regarding my talk at #fosdem2024 from yesterday: if you want to tell your story about #flakytests, please get in contact, either via k8s Slack to @dhiller, via [email protected], messages via Mastodon, whatever suits you best.

I'm really sad that that didn't happen yesterday, since I am convinced now that there are lots of stories to tell.

Idea: create a repository for flaky tests stories and use pull requests to add stories... WDYT?

I'm ready to travel to #FOSDEM in #Brussels, where I'll be giving a talk about #FlakyTests ! It will start on Sunday 11:10 CET in the Testing & Continuous Delivery Developer Room.

Besides describing how #KubeVirt CI team deals with #FlakyTests, I hope to gather insights from the attendees, so please come over and share your thoughts in the Q&A at the end of the session! (Offline is great also for sure :) )

If there is more than one call to `faker.seed` in your entire test suite then you are *very* likely to hit many problems once the code grows big.

One of the easiest way to show almost guaranteed free lying rake is the concept of IDs that in most cases *need* to be unique for different instances of the same model. For that faker has cool function `uuid()` that promise to give you exactly that ... unless you use `seed`:

```
faker.seed(1);
const uuid1 = faker.datatype.uuid();

...

faker.seed(1);
const uuid2 = faker.datatype.uuid();

console.log(uuid1 === uuid2); // true
```

There are many others and even if you think this does not apply to your case the unnecessary risk is IMO way too high to instil this in your code.

The hidden cost of flaky tests: If you are a software engineer, you probably know the frustration of dealing with flaky tests. In the blog The hidden cost of flaky tests I explain the costs of flaky tests in terms of quality, productivity, and morale. And provide some practical tips on how to prevent, detect, and fix flaky tests using tools and best practices.
