In this episode, I'm joined by Vitaly Sharovatov, Developer Advocate at Qase, to dive into one of the most overlooked yet impactful practices in software development: developers testing their own code.We explore how shifting testing left—having developers test while building—saves time, avoids costly context-switching, and prevents bugs or misunderstandings from slipping through to QA or production. Vitaly also shares insights on how to structure your test strategy, balance manual vs. automated testing, and how tools like Qase can help teams stay organized and efficient with Test Management Systems (TMS).Whether you're building solo or as part of a larger team, this conversation offers practical advice for writing more reliable code before it becomes someone else’s problem.Link to the video on YouTube:https://youtu.be/2ouS1rMTM74Links and References► Qase:https://qase.io/► ESP32 Weather Station project repository:https://github.com/sharovatov/esp32-wsVitaly SharovatovDeveloper advocate @ Qase, Manager, Engineer, and Mentor► https://www.linkedin.com/in/vsharovatovFollow me on:► Twitter⁠⁠⁠⁠⁠⁠⁠⁠⁠https://twitter.com/@mohsenoid⁠⁠⁠⁠⁠⁠⁠⁠⁠► Mastodon⁠⁠⁠⁠⁠⁠⁠⁠⁠https://mastodon.social/@mohsenoid@androiddev.social⁠⁠⁠⁠⁠⁠⁠⁠⁠► Medium⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://medium.com/@mohsenoid⁠⁠⁠⁠⁠⁠⁠⁠⁠► YouTube⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.youtube.com/@AndroidDeveloperTips⁠

The "fun code()" magazine is a one-time publication about Kotlin, created by Kotlin developers for Kotlin developers, and I had the pleasure of being one of the contributors. It was released during KotlinConf 2024 and received significant attention.In this exciting episode, I had the opportunity to gather some of the key individuals involved in producing this paper magazine so we could discuss it. We discussed how the idea started, what the magazine includes, and the stories behind it.Link to the video on YouTube:https://youtu.be/SEBRBnh61nILinks and References ► Website:https://kotlintoday.com/► GitHub repo:https://github.com/kotlin-magazine/kotlin-magazine► Twitter:https://twitter.com/@funcode_mag► Mastodon:https://mastodon.social/@funcode_magAttendees in Alphabetical OrderChet Haase► Twitter:https://twitter.com/@chethaaseEnrique López Mañas► Twitter:https://twitter.com/@eenriquelopezMarc Reichelt► Twitter:https://twitter.com/@mreichelt► Mastodon:https://mastodon.social/@mreicheltMario Bodemann► Mastodon:https://androiddev.social/@mariobodem...Mariusz Sołtysiak► LinkedIn:https://www.linkedin.com/in/mariusz-s...► Blog:https://kotlinbackend.com/Matthias Geisler► Twitter:https://twitter.com/@BitPogoNicole Terc► Twitter:https://twitter.com/@nicole-terc► Mastodon:https://androiddev.social/@nicole_tercSiggi Gunnarsson► Twitter:https://twitter.com/sigurdur► Mastodon:https://mastodon.online/@sigurdurThanks to Guillem Roca for the KotlinConf 2024 incident video:► https://x.com/6uillemRoca/status/1793...
