Frequently Asked Questions

What is Shift Left approach in testing?
The Shift-left approach in testing advocates to begin testing as soon as possible. It is based on the principle that if you can test code as it is being written rather than waiting until the end of the project, you will discover errors earlier. The shift-left testing approach allows testers to uncover issues before developers begin writing code or other development activities.
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.
What is Shift left principle?
The principle of Shift Left is to move testing leftward in the development process. This means that we do testing much earlier in the development process. This benefits everyone involved because problems can be fixed sooner, while they're still easy to solve and cheaper. Companies should embrace Shift Left Testing to prevent issues late in the software development process.
What is Shift Left in DevSecOps?
The phrase “shift left” refers to the practice of taking a task that’s traditionally performed later in the development process and performing it early on. The goal of shift-left in DevSecOps is to guarantee application security at all stages of the software lifecycle.
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 2000 browsers and operating systems, resulting in higher test coverage and much shorter build times. Refer to our Selenium Automation testing documentation .
