  • Observability in Testing with ElasTest

    In a distributed application it is difficult to use debugging techniques common in developing non-distributed applications. Bringing production observability to your testing environment helps to find bugs, argued Francisco Gortázar at the European Testing Conference 2019. He presented ElasTest, a tool for developers to test and validate complex distributed systems using observability.

  • Debugging Microservices Running in Containers: Tooling Review at KubeCon NA

    At KubeCon NA held in Seattle in December 2018, several tools for debugging containerised microservices were presented throughout the conference sessions and the sponsored booths demonstrations. A notable separation appears to be occurring within the market, between "active" and "passive" debugging tools. Two examples within these categories are Rookout and Squash, respectively.

  • Webhint Open Source Linting Tool for Detecting Issues with Accessibility, Performance, and Security

    The webhint project provides an open source linting tool to check for issues with accessibility, performance, and security. The creation of websites and web apps has an increasing number of details to perfect, and webhint strives to help developers remember these details.

  • Understanding Production with DevOps Archeology

    Lee Fox spoke at Continuous Lifecycle London about tools and methods to help make sense of today’s complex systems and infrastructure; he calls it DevOps archeology.

  • Facebook Sonar Is a Visual and Interactive Debugging Tool for Mobile Apps

    Facebook Sonar is an open-source toolset that aims to help developers inspect and understand the structure and behaviour of iOS and Android apps in a visually rich, interactive, and extensible way.

  • Microsoft Introduces Edge DevTools Protocol

    With the April 30 release of Edge version 17, Microsoft has announced the availability of the Microsoft Edge DevTools Protocol, a set of JSON and JSON-RPC APIs that enable clients to interact with Microsoft Edge tabs. Following the model of the Chrome DevTools Protocol, the Edge DevTools Protocol enables independent developers to build tools that interact with Edge using standard web technologies.

  • How Observability Impacts Testing: Q&A with Amy Phillips at QCon London

    Observability gives you a picture of the system’s current health and can replace certain types of testing. For low-risk application areas you can rely on observability instead of testing, provided you have continuous delivery that provides fast feedback and allows you to release changes quickly.

  • Visual Studio Code Announces JUnit Support

    The team at Microsoft which supports Visual Studio Code (better known as VS Code) has announced the release of an extension to run and debug Java JUnit test cases. The extension works with the Java Language Support extension provided by Red Hat and the Debugger for Java to complete the end-to-end development experience for developers working in the Java language in the editor.

  • Debugging Containerized Microservices: Idit Levine at QCon SF

    At QCon San Francisco Idit Levine presented “Debugging Containerized Microservices”, and outlined the issues of debugging a distributed microservice-based system, and provided three potential approaches to overcome the inherent challenges. The talk also introduced a new open source microservices debugger that Levine is working on, Squash, which integrates with the VS Code IDE.

  • LLVM Has Documented the PDB Format, Complete with PDB to YAML Conversion

    LLVM can now generate PDB files, allowing the use of Windows debugging tools. In addition, they have documented the format and created tooling for analyzing with and generating PDB files from YAML.

  • Oracle Releases Open Source Container Utilities, Including A New Container Runtime Written in Rust

    Oracle has released three open source container utilities including Smith, an OCI image-compliant container builder that creates “microcontainers” with a single executable and its dependencies; Crashcart, a microcontainer debugging tool; and Railcar, a Rust-based alternative container runtime that implements the OCI-runtime specification.

  • AWS Lambda Support Added to AWS X-Ray Distributed Tracing Service

    Following from the General Availability (GA) release of the AWS X-Ray distributed tracing service in April, Amazon has added AWS Lambda support for AWS X-Ray, enabling function invocations and associated metadata to be recorded, displayed graphically via the AWS Console, and analysed for debugging or fault resolution purposes.

  • Updates to Google Chrome DevTools

    The upcoming version of Chrome DevTools has a number of new features that can help developers build faster web pages and have an easier time debugging complex asynchronous code. At Google I/O 2017, Paul Irish presented a State of the Union showcasing a number of these new features.

  • Microsoft Adds Application Insights Support for Azure Functions

    Microsoft recently announced an initial preview of Application Insights support for Azure Functions. As a result of this integration between the two services, developers now get built-in instrumentation for their code and a portal to view trends in their code’s performance. Developers are also able to set monitoring thresholds which can be used to create alerts or a callout to external webhooks.

  • Honeycomb - A Tool for Debugging Complex Systems

    Honeycomb is a tool for observing and correlating events in distributed systems. It provides a different approach from existing tools like Zipkin in that it moves away from the single-request-tracing model to a more free-form model of collecting and querying data across layers and dimensions.
