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.

We can provide a more specific service upon request. For example, to employ the client’s QA team for the test run, we can prepare test source files and license the required WAPT Pro components. We can also assist with the analysis of the results after the test is completed. On average, one-time testing projects are completed in a week while recurring arrangements are also available. Additionally, we can help establish a client testing environment for regression testing. Test development may be a complex task, because each emulated session must be unique and consistent. Unless the website consists of exclusively static pages, there is no testing tool that can fully automate the test design process. In many cases the implementation may require considerable research of the client-server communication scheme. While a good testing tool may create a detailed report with data and charts showing different performance parameters.

Automated testing has come of age with Progress® Telerik® Test Studio. With the industry's fastest test recorder, its patent-pending mixed element find logic makes tests more stable and reliable while keeping test maintenance to a minimum. Test Studio maximizes test coverage ensuring optimal app quality and addresses QA’s top challenges. Testing is a must to meet the delivery cycles of Agile/CI/CD and keep bugs out of final products, but the demand to quickly deliver digital experiences, additional capabilities and improvements puts pressure all around. Meanwhile, most of the automated testing approaches aren’t designed to support QA testers without much coding experience. Simply record your test and use automated playback for an easy and fast way to craft your test and then run that same script to test multiple browsers. Maintenance is greatly reduced with patent-pending element detection, centralized object repository, intelligent suggestions and multi-mechanism element search.

Massive concerns around security are driving an increased use of encryption. An all-encrypted world is not far away. At the same time, the scale of traffic continues to grow at an exponential rate and the industry is moving to new cloud-based architectures. Users of services and applications, however, continue to expect their experience to be at or above the current level. To keep pace, network equipment manufacturers race to build higher-scale, more capable network security and application delivery solutions. In turn, the world’s largest cloud data center operators struggle to find the right balance between performance and security in today’s hyper-scale, dynamic world. The uncertainty that comes with this change is best mitigated through cloud-scale validation.
