LambdaTest is a cloud-based cross browser testing platform that helps enterprises run web automation tests at scale (through parallel testing).

Selenium Automation Grid and Cypress CLI on LambdaTest You can attain better browser coverage by running tests across 2,000+ different browsers, devices, and operating systems online. LambdaTest provides a secure, scalable, and reliable cloud-based Selenium Grid that helps run Selenium tests at a faster pace. The Cypress CLI on LambdaTest, helps you expand Cypress test coverage to 40+ browser versions across Windows and macOS platforms. Along with automation testing, you can also perform manual tests, visual UI tests, and real-time tests.

**LT Browser - Responsive Web Testing* Additionally, LambdaTest also offers complimentary access of LT browser - a path-breaking developer-oriented tool that helps assess the responsiveness of your website. LT Browser eases the task of mobile testing as responsive tests can run against 50+ different device resolutions. You can also create custom device (or viewports) and test localhost URL without any extensions (or tunnels).

Zephyr features and specs

  • Scalability
    Zephyr is designed to be scalable and can support applications from small embedded devices to larger systems with resource constraints.
  • Modularity
    The kernel is highly modular, allowing developers to include only the components needed for their specific application, which helps in optimizing resource usage.
  • Support for Multiple Architectures
    Zephyr supports a wide range of hardware architectures, including x86, ARM, RISC-V, and others, making it versatile for different hardware platforms.
  • Real-time Capabilities
    Zephyr has built-in real-time operating system (RTOS) capabilities, which are crucial for time-sensitive applications and can meet stringent timing requirements.
  • Security Features
    Zephyr includes multiple layers of security, such as memory protection, kernel object permission, and stack overflow protection, to help secure embedded applications.
  • Community and Ecosystem
    Backed by the Linux Foundation, Zephyr has a strong community and ecosystem, which means robust support, extensive documentation, and continuous development.
  • Open Source
    Zephyr's open-source nature enables transparency, community contributions, and the ability for organizations to customize the OS to their specific needs.

Possible disadvantages of Zephyr

  • Complexity
    Due to its modular and scalable nature, Zephyr can be complex to set up and configure, especially for beginners who may find the learning curve steep.
  • Limited Middleware
    While Zephyr supports a variety of hardware, its middleware offerings may not be as extensive or mature as those provided by more established OSes like FreeRTOS.
  • Documentation Gaps
    Although the community is active, there are areas where documentation could be more comprehensive and detailed, which can hinder quick adoption and troubleshooting.
  • Resource Intensive
    Given its wide range of features and capabilities, Zephyr can sometimes be more resource-intensive compared to more minimalist RTOS options, which might be a concern for extremely resource-constrained environments.
  • Vendor Lock-in Risk
    While Zephyr aims to be vendor-neutral, there can be dependencies on certain hardware platforms or vendors, which might lead to a form of vendor lock-in.

    LambdaTest an essential tool for cross browser compatibility

    Initially we were skeptical whether a cloud infrastructure would be able to give us the flexibility, speed and browser coverage we need for our agile sprints. But LambdaTest has been a complete value for money to us.

    They usually get the latest browsers on-board under 2 weeks time and are never compromising the experience over legacy browsers at the same time. The machines are quick to load and we rely heavily over the Monday integration, it helps us share screenshots instantly among ourselves without having to be stuck in long email chains.

    We have been using LambdaTest for around 8 months and it has been so far so good.

    🏁 Competitors: Sauce Labs, CrossBrowserTesting
    👍 Pros:    Underpass app, very helpful for local testing on development environment|Stability is good, downtimes are notified if any|Up to date with latest browsers and os like safari 14, macos big sur|Integrations with monday, jira, and more prominent tools
    👎 Cons:    Need more devices for screenshot testing|Would love to see mobile application testing

    LambdaTest Our Go-To Platform For Selenium Testing

    LambdaTest has made our testing process less tedious with automated parallel testing. Builds that took days to complete with in-house infrastructure were executed in a couple hours. Parallel testing has helped us with faster feedback loops to scale up our go to market efforts.

    Having a global user base we have active traffic from varied locations and testing on multiple platforms and browsers is a continuous process for the team. The feature that stands out for us is geolocation testing, all you need to do is run the capabilities and test the website for the desired location. We use Azure Pipelines for CI/CD and LambdaTest extension for Azure has helped us get a seamless testing experience for our privately hosted projects. Thanks to that we are now able to easily ensure browser compatibility for all the changes before we move them to Prod. Kudos to the team!

    🏁 Competitors: Sauce Labs, CrossBrowserTesting
    👍 Pros:    Support team is very active|Extensions to perform testing with ci/cd tools like azure pipelines|Always up to date with latest browsers|Offers 70+ integrations, glad to see it integrates with jira|Affordable pricing option
    👎 Cons:    Cypress integration is missing|Native app testing is not available yet

    Easy, Useful and provides lots of data for debugging

    Have been using Lambdatest for around 6 months now, and could say that it’s a useful testing tool for our team. Offering great combinations of browsers and operating systems for you to test on and most importantly there are many types of additional logs that come with each test which helps in debugging.. Glad to see the integration with Travis CI due to which we could optimally use this tool with our CI CD pipelines directly. We were able to effectively run TestNG and Selenium tests using their documentation and as an added advantage their support team is quick and helpful

    🏁 Competitors: Sauce Labs, CrossBrowserTesting
    👍 Pros:    Detailed documentation, helps you with quick implementation|Apis for extracting test run data like logs and run video|Good community to help to dig deep for possible outcomes.|Screenshot testing feature|Integration with jira
    👎 Cons:    There is a latency in a single test when compared to a local machine. maybe because of the cloud? so you have to run in parallel to cut down on testing times.

Zephyr mentions (11)

  • A Web based Broadcast Assistant
    Combining the Zephyr RTOS stack, running on an affordable nRF52840 Dongle with the power of modern web technologies turned out quite well and it has also allowed us to experiment with multiple subgroups, supported by the specs, but not yet by many devices in the market (at the time of writing at least - be sure to keep an eye out for that!). - Source: dev.to / 2 months ago
  • Auracast and multiple subgroups
    Also, it's really great to see that the RFcreations mini-moreph and blueSpy software was able to capture and render this slightly more advanced source and that it was possible to build using Zephyr RTOS and the nRF52840 Dongle. - Source: dev.to / 2 months ago
  • A simple Broadcast Audio Source
    The Zephyr RTOS contains some great Bluetooth LE Audio related samples. One of them is the Basic Audio Profile (BAP) Broadcast Source sample. - Source: dev.to / 2 months ago
  • Capturing the perfect (radio) wave
    I thought about what would be a good first capture, and remembered, I recently made a very simple Bluetooth Low Energy demo using Zephyr and Web, covered in an earlier post. - Source: dev.to / 6 months ago
  • It's 2023 why embedded development is so cumbersome?(rant)
    Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino. Source: over 1 year ago
