Frequently Asked Questions

What is UI in automation testing?
Automated User Interface (UI) testing is a process to execute test scripts automatically to save time and bandwidth for manual tetsing. With Automated Web UI Testing, instead of a tester clicking through your application, you create a script or an automated test to perform the same actions that a manual tester might take for an application under test.
What is parallel testing?
Parallel testing is one of the best ways to cut down overall test execution time of the whole test build. If you have test builds of multiple tests, parallel testing at LambdaTest will allow you to run these Selenium webdiver tests across multiple machines simultaneously. so if you have a build of 100 tests, and are subscribed on 10 parallel testing plan, then you can run upto 10 test threads simultaneously across 10 machines. Running tests in parallel will cut down drastically your overall build test execution times.
What is HyperExecute?
HyperExecute is an unique LambdaTest platform aimed at enabling teams executing thier test scripts at the fastest possible times. HyperExecute is an innovative new take on test execution on cloud and runs tests at speeds that even exceeds the local test execution speeds. The platform is flexible enough to run on VMs, MacOS infrastucure, and even Containers. And the best part is that it costs as much as spot instance cloud.
Why do we need UI Automation testing?
The purpose of automated UI Testing is offload testers from mundane and repetitive test cases so they could focus on finding critical bugs for the application. Automated Web UI Testing is especially useful for daily sanity checks and regression testing, helping testers save a lot of time, effort and bandwidth.
Can we automate UI using Selenium?
Selenium is a one of the most popular open-source framework avaiable for UI test automation. It allows you to automate any interaction inside a browser. Selenium is compatible with all major programming languages and supports all major browsers to help testers perform automated browser testing, effortlessly.
How can I automate with Selenium using LambdaTest?
The LambdaTest Selenium Automation Grid allows you to run end-to-end automation tests on a secure, robust, and scalable Selenium infrastructure. You can perform automated cross-browser testing across 3000 browsers and operating systems, resulting in higher test coverage and much shorter build times. Refer to our Selenium Automation testing documentation .
