Top Alternatives to Panther

  • Puma

    Puma

    Unlike other Ruby Webservers, Puma was built for speed and parallelism. Puma is a small library that provides a very fast and concurrent HTTP 1.1 server for Ruby web applications. ...

  • Selenium

    Selenium

    Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well. ...

  • BrowserStack

    BrowserStack

    BrowserStack is a leading software testing platform for developers to comprehensively test their websites and mobile applications across 2,000+ real browsers and devices in a single cloud platform—and at scale. ...

  • Karma

    Karma

    Karma is not a testing framework, nor an assertion library. Karma just launches a HTTP server, and generates the test runner HTML file you probably already know from your favourite testing framework. So for testing purposes you can use pretty much anything you like. ...

  • LambdaTest

    LambdaTest

    LambdaTest is a highly scalable testing platform on cloud. Mainly it provides Selenium Automation Grid with 2000+ browser-OS combinations, Cypress CLI test coverage to 40+ browser versions, and Mobile app testing infrastructure. ...

We switched from Unicorn (process model) to Puma (threaded model) to decrease the memory footprint of our Rails production web server. Memory indeed dropped from 6GB to only 1GB!

We just had to decrease our worker count and increase our thread count instead. Performance (response time and throughput) remained the same, if not slightly better. We had no thread-safety errors, which was good.

Free bonus points are:

  • Requests are blazing fast on our dev and staging environments!
  • Puma has first-class support for WebSockets, so we know for sure that Rails ActionCable or GraphQL subscriptions will work great.
  • Being on Puma makes us even more "default Rails"-compliant since it is the default Rails web server these days.

When you think about test automation, it’s crucial to make it everyone’s responsibility (not just QA Engineers'). We started with Selenium and Java, but with our platform revolving around Ruby, Elixir and JavaScript, QA Engineers were left alone to automate tests. Cypress was the answer, as we could switch to JS and simply involve more people from day one. There's a downside too, as it meant testing on Chrome only, but that was "good enough" for us + if really needed we can always cover some specific cases in a different way.

For our digital QA organization to support a complex hybrid monolith/microservice architecture, our team took on the lofty goal of building out a commonized UI test automation framework. One of the primary requisites included a technical minimalist threshold such that an engineer or analyst with fundamental knowledge of JavaScript could automate their tests with greater ease. Just to list a few: - Nightwatchjs - Selenium - Cucumber - GitHub - Go.CD - Docker - ExpressJS - React - PostgreSQL

With this structure, we're able to combine the automation efforts of each team member into a centralized repository while also providing new relevant metrics to business owners.

I am working on #OpenSource file uploader. The uploader is the widget that other developers embed in their apps. It should work well in different browsers and on different devices. BrowserStack and Sauce Labs help to achieve that. I can test the uploader in many varieties of browsers+OS only used my browser without virtual machines.

Protractor or Cypress for ionic-angular?

We have a huge ionic-angular app with almost 100 pages and 10+ injectables. There are no tests written yet. Before we start, we need some suggestions about the framework. Would you suggest Cypress or Angular's Protractor with Jasmine / Karma for a heavy ionic app with Angular?

Switched from Jasmine with Karma that come setup by Angular CLI to use Jest instead, since Jasmine and Karma were very finicky in my setup and had to be reconfigured frequently to run tests properly.

Jest was also easier to integrate into my workflow with Visual Studio Code.

      I am looking to purchase one of these tools for Mobile testing for my team. It should support Native, hybrid, and responsive app testing. It should also feature debugging, parallel execution, automation testing/easy integration with automation testing tools like Selenium, and the capability to provide availability of devices specifically for us to use at any time with good speed of performing all these activities.

      I have already used Perfecto mobile, and Sauce Labs in my other projects before. I want to know how different or better is AWS Device farm in usage and how advantageous it would be for us to use it over other mentioned tools

      Currently, we are using Protractor in our project. Since Protractor isn't updated anymore, we are looking for a new tool. The strongest suggestions are WebdriverIO or Puppeteer. Please help me figure out what tool would make the transition fastest and easiest. Please note that Protractor uses its own locator system, and we want the switch to be as simple as possible. Thank you!

      I chose WebdriverIO and Appium to implement a E2E tests solution on a native mobile app. WebdriverIO goes well beyond just implementing the Selenium / Appium protocol and allows to run tests in parallel out of the box. Appium has the big advantage of supporting iOS and Android platforms, so the test codebase and tools are exactly the same, which greatly reduces the learning curve and implementation time.
