Vaisala Oyj, Finland
Go Find What We May Have Missed!

Coming into software with an exploratory testing mindset is like coming to a multi-layer canvas with lots of information and an open ended task: find what we may have missed! This is the assignment for us all in software teams in our quest for quality.

Framing the search of how our system falls short of expectations is easier when we are able to see software from its user’s perspective. However, useful tests aren’t a collection of end-to-end tests we automate, but great tests to leave behind will decompose the testing problem differently. In this talk, we learn about using architecture as a filter in decomposing tests and look at an example of taking control over the API responses to test a React frontend.

Users don’t know or care if the problem is in the frontend and services your team provided if it fails to meet their expectations but you care. Granularity of feedback matters. Recognizing the same problems in incomplete scope - half-done features or only in frontend or APIs - is a skillset the software industry needs to be building.

Testing Pyramid Makes Little Sense, What We Can Use Instead

The testing pyramid - the canonical shape of tests that defined what types of tests we need to write to make sure the app works - is ... obsolete. In this presentation, Roman Sandler and Gleb Bahmutov argue what the testing shape works better for today's web applications.

Snyk, Israel
Are we Forever Doomed to Software Supply Chain Security?

The adoption of open-source software continues to grow and creates significant security concerns for everything from software supply chain attacks in language ecosystem registries to cloud-native application security concerns. In this session, we will explore how developers are targeted as a vehicle for malware distribution, how immensely we depend on open-source maintainers to release timely security fixes, and how the race to the cloud creates new security concerns for developers to cope with, as computing resources turn into infrastructure as code.

Cypress.io, USA

How Low-Code Enables Continuous Testing in DevOps

As an industry, we understand that effective test automation is a key enabler - or inhibitor to - realizing the potential of DevOps. While automation is critical to innovating with speed and quality, very few of us are happy with the results. This talk will cover how low-code test automation solutions - like mabl - enable teams to embed automated tests directly into the development pipeline, strategies to overcome traditional challenges with test automation, and how to build a foundation for an efficient and effective test strategy.

Who Guards the Guards? – Finding Bugs in Your Tests - Tibor Blenessy

Nowadays, testing has become the norm. There are many tools available to write different kinds of tests. While tests keep the guard on the main code of the application, how can you be sure that you don’t have bugs hiding in your test code? Should you write tests for the tests?

In this lighting talk I will show you a different approach on how you can eliminate certain types of issues from your tests using static code analysis tools like SonarLint or SonarQube. We will focus on common issues found in tests using frameworks such as Mocha and Chai.

Why Tracing is a Lifesaver for E2E Tests of Distributed Systems? - Burak Kantarci

Contemporary software systems are often built on a microservices architecture pattern. In this pattern, rather than build one huge code-base for a single application, systems are separated into multiple smaller code-bases. These implement services that provide a specific feature, like authentication or monitoring, and those services can have performance problems, network issues, or bugs in their code – any of which can lead to failing tests. If you want to solve such problems, you have to go a step further than just logging your errors – it is best for you to monitor your tests with distributed tracing. This talk will show you why a tracing system will rescue you from the complexity of understanding why an E2E test has failed in a distributed architecture.

JS Do It.....Accurate Security Testing Automation for Developers - Oliver Moradov

NeuraLegion's developer friendly security scanner enables development teams to run dead accurate security tests on every build as part of their pipeline. False alerts and periodic infrequent scanning results in technical and security debt, as well as insecure product. But what is developer first DAST, when and how should you be integrating it into your pipelines and what should you be looking for when enhancing your security testing automation? Join this talk to get up to date.

Test Time Execution! Why it Can't be Ignored? - Jay Singh

For modern agile teams, release velocity is very critical. Unfortunately, one of the biggest bottlenecks for faster release velocity is testing times. Even after teams implement end-to-end test automation, long testing times significantly delay the pipelines. This delay means developers get feedback of their efforts very late, which can snowball, affecting the shipping velocity. Hence test execution time becomes one of the most critical KPIs for any business that wants to ship features faster than the approaching deadlines. LambdaTest helps modern dev teams release faster by executing tests faster on a scalable, reliable test cloud.

HiRez.io, Israel
Test Effective Development

Developers want to sleep tight knowing they didn't break production. Companies want to be efficient in order to meet their customer needs faster and to gain competitive advantage sooner. We ALL want to be cost effective... or shall I say... TEST EFFECTIVE!

  • But how do we do that?
  • Are the "unit" and "integration" terminology serves us right?
  • Or is it time for a change? When should we use either strategy to maximize our "test effectiveness"?

In this talk I'll show you a brand new way to think about cost effective testing with new strategies and new testing terms!

It’s time to go DEEPER!

It's a (Testing) Trap! - Common Testing Pitfalls and How to Solve Them

It’s a trap” - a call or feeling we all might be familiar with, not only when it comes to Star Wars. It’s signalizing a sudden moment of noticing imminent danger. This situation is an excellent allegory for an unpleasant realization in testing. Imagine having the best intentions when it comes to testing but still ending up with tests failing to deliver you any value at all? Tests who are feeling like a pain to deal with?

When writing frontend tests, there are lots of pitfalls on the way. In sum, they can lead to lousy maintainability, slow execution time, and - in the worst-case - tests you cannot trust. But it doesn’t have to be that way. In this session, I will talk about developers’ common mistakes (including mine), at least from my experience. And, of course, on how to avoid them. Testing doesn’t need to be painful, after all.

[Your Company], Germany
Tests That Help you Find Defects Faster

This talk is about common mistakes people make when writing tests.

Mixing multiple concerns inside tests is tempting because it can feel like painting the whole picture. However, it obfuscates the root cause when a test fails. Setup methods are great but when developers are too focussed on keeping their tests DRY they can easily lead to test interdependence. Therefore, some principles we have learned to build our software we need to unlearn when it comes to testing.

The talk highlights more aspects like bloated tests which make it hard to figure out what they are about and proper usage of assertions to get better error messages.

Especially if you don't work with TDD it can be easy to come up with a test that looks good but stands in your way when it fails.

The talk will have a look at the four scenarios I outlined above, explain why it makes sense to think about them and actionable suggestions how to improve tests.

Visual Regression with Puppeteer, Playwright and Cypress - Rainer Hahnekamp

Visual Regression tests components via screenshot matching. I'll show how you do that in three different libraries/frameworks. Additionally, I will use Storybook to extract the components from your SPA of choice.

E2E Tests for API – Saving Nerves and Hours - Valentin Kononov

Having adequate test coverage means a lot for the good API. But what can make the whole life pathetic is endless mocking of data and functions for integration tests. Every time you've changed the code you need to fix the mock. After several iterations the correct thought is - what's went wrong?

Alternative approach is e2e tests for the API. Which require only minimal mocks and data preparation. The rest - pure code of your API. Change the code - e2e test remains the same.

This talk is about my experience of switching from integration tests to e2e tests for the API, proc and cons and how I started to feel happy about tests.

Who is Testing the Tests? - Simon de Lang

Have you ever wondered: "who's testing the tests"? Of course, tests are only valuable if they catch bugs, but how would one validate that? Well, let me tell you about mutation testing!

Mutation testing is the act of testing your test by verifying that they catch bugs. Of course, you can do this manually by inserting bugs and running the tests, but a mutation testing framework can do this for you!

Join me and learn the basics of mutation testing and how to use StrykerJS, the mutation testing framework for JavaScript or TypeScript.

At the end of this talk, you'll be the one that is testing your tests, and it won't even cost you much time!

How to Catch a11y Defects During Unit and E2E Testing - Emily Xiong

For developers, it is better to catch any a11y defects during unit and e2e testings. This talk is going to show how to automate a11y testing using jest and cypress.

In this advanced session, we'll be learning how to configure axe and its integrations to fine tune how it runs and checks your pages and code for accessibility violations.

Chromatic, Netherlands
Test your UI in the REAL Browser

Imagine writing a complex function without unit tests. You would have to verify every scenario manually, over and over again. Cumbersome, but that's how most teams build user interfaces.

Imagine if you could build UIs and test UIs in the same place. If your components included expectations for how they were supposed to behave, you'd know the instant they broke.

Storybook provides an organized approach to building UIs. You document a component's use-cases as stories, which are then rendered in isolation. Stories are like tests, but for UI. Storybook interaction testing allows you to script interactions and check expectations in the story itself. That allows you to run and debug UI tests in the same environment UI components are developed for: your browser.
