The dual-write problem occurs when two external systems must be updated in an atomic fashion. A classic example is updating an application’s database while pushing an event into a messaging system like Apache Kafka. If the database update succeeds but the write to Kafka fails, the system ends up in an inconsistent state. However, the dual-write problem isn’t unique to event-driven systems or Kafka. It occurs in many situations involving different technologies and architectures.

In our previous articles about exploratory testing, we focused on session-based test management (SBTM), one of the more popular approaches. SBTM aligns clearly with the Xray Exploratory App workflow and terminology. As a quick refresher, SBTM is a more structured technique for performing exploratory testing. The key idea is to organize delimited sessions which are uninterrupted blocks of reviewable, chartered test effort.

Kevin McGahey - May 28, 2024 It’s been a while since our last update, but while we’ve been AWOL, we most certainly haven’t been AFK. Here’s a brief summary of what we’ve been up to since the last update.

NASA Jet Propulsion Laboratory’s Laboratory for Reliable Software developed a set of code guidelines for developing safety-critical code. The NASA's 10 rules are intended to eliminate C coding practices that make it difficult to review or properly analyze with static analysis tools. Enforce NASA's 10 Rules With Klocwork.

Building quality software requires efficient and effective software testing processes. To achieve this, it’s important to make sure your test management tool has the capabilities to support your team’s current, and future, testing needs. By following this three-step approach, you can narrow down your choices and find your perfect fit. Break out your notepad and follow along to see if your team’s needs are best described by options A, B, or C.
