    Selenium

    Selenium

    Software Freedom Conservancy

    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. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point.

    LoadNinja

    LoadNinja

    SmartBear

    Diagnose web UI and API performance issues with data that’s highly actionable and extremely accurate. Traditional performance testing has always happened in the protocol layer. This results in massive tests that are hard to read, require extensive programming, and take hours, even weeks to set up. Even the results aren’t even indicative of the real world as they test the protocol. No wonder performance testing seemed hard. But it doesn't have to be with LoadNinja. Instead of testing the protocol, test the actual end-user experience across tens of thousands of browsers using our TrueLoad technology, saving you over 60% of effort. No maintenance or setup required to give you the most accurate understanding of performance in the least amount of time possible. Increase test coverage for websites, web apps, and APIs without sacrificing quality. Create complex performance tests without complex correlation.
