As everyone knows, the mobile industry has taken over the world and is the fastest emerging industry in terms of technology and business. It is possible to do all the tasks using a mobile phone, for which earlier we had to use a computer. According to Statista, in 2021, smartphone vendors sold around 1.43 billion smartphones worldwide. The smartphone penetration rate has been continuously rising, reaching 78.05 percent in 2020. By 2025, it is expected that almost 87 percent of all mobile users in the United States will own a smartphone.
Coaching is a term that is now being mentioned a lot more in the leadership space. Having grown successful teams I thought that I was well acquainted with this subject.
So you are at the beginning of 2020 and probably have committed a new year resolution as a tester to take a leap from Manual Testing To Automation . However, to automate your test scripts you need to get your hands dirty on a programming language and that is where you are stuck! Or you are already proficient in automation testing through a single programming language and are thinking about venturing into new programming languages for automation testing, along with their respective frameworks. You are bound to be confused about picking your next milestone. After all, there are numerous programming languages to choose from.
The best agile teams are built from people who work together as one unit, where each team member has both the technical and the personal skills to allow the team to become self-organized, cross-functional, and self-motivated. These are all big words that I hear in almost every agile project. Still, the criteria to make a fantastic agile team are practically impossible to achieve without one major factor: motivation towards a common goal.
Mobile application development is on the rise like never before, and it proportionally invites the need to perform thorough testing with the right mobile testing strategies. The strategies majorly involve the usage of various mobile automation testing tools. Mobile testing tools help businesses automate their application testing and cut down the extra cost, time, and chances of human error.
