How to run a list of test suites in a single file concurrently in jest?
Well this is one way, but not sure if it will work for all possible locators!.
// Get a selector from a playwright locator
import { Locator } from "@playwright/test";
export function extractSelector(locator: Locator) {
const selector = locator.toString();
const parts = selector.split("@");
if (parts.length !== 2) { throw Error("extractSelector: susupect that this is not a locator"); }
if (parts[0] !== "Locator") { throw Error("extractSelector: did not find locator"); }
return parts[1];

How Testers Can Remain Valuable in Agile Teams
Traditional software testers must step up if they want to remain relevant in the Agile environment. Agile will most probably continue to be the leading form of the software development process in the coming years.
Project Goal Prioritization in Context of Your Organization’s Strategic Objectives
One of the most important skills for leaders to have is the ability to prioritize. To understand how we can organize all of the tasks that must be completed in order to complete a project, we must first understand the business we are in, particularly the project goals. There might be several project drivers that stimulate project execution and motivate a company to allocate the appropriate funding.
Automated App Testing Using Appium With TestNG [Tutorial]
In recent times, many web applications have been ported to mobile platforms, and mobile applications are also created to support businesses. However, Android and iOS are the major platforms because many people use smartphones compared to desktops for accessing web applications.
How To Choose The Right Mobile App Testing Tools
Did you know that according to Statista, the number of smartphone users will reach 18.22 billion by 2025? Let’s face it, digital transformation is skyrocketing and will continue to do so. This swamps the mobile app development market with various options and gives rise to the need for the best mobile app testing tools
Do you possess the necessary characteristics to adopt an Agile testing mindset?
To understand the agile testing mindset, we first need to determine what makes a team “agile.” To me, an agile team continually focuses on becoming self-organized and cross-functional to be able to complete any challenge they may face during a project.
