Complete Tutorial On Appium Parallel Testing [With Examples]

In today’s fast-paced world, the primary goal of every business is to release their application or websites to the end users as early as possible. As a result, businesses constantly search for ways to test, measure, and improve their products. With the increase in competition, faster time to market (TTM) has become vital for any business to survive in today’s market. However, one of the possible challenges many business teams face is the release cycle time, which usually gets extended for several reasons.

Three Techniques for Improved Communication and Testing

Anyone who has worked in the software industry for a while can tell you stories about projects that were on the verge of failure. Many initiatives fail even before they reach clients, which is especially disheartening when the failure is fully avoidable.

Considering Agile Principles from a different angle

In addition to the four values, the Agile Manifesto contains twelve principles that are used as guides for all methodologies included under the Agile movement, such as XP, Scrum, and Kanban.

New Year Resolutions Of Every Website Tester In 2020

Were you able to work upon your resolutions for 2019? I may sound comical here but my 2019 resolution being a web developer was to take a leap into web testing in my free time. Why? So I could understand the release cycles from a tester’s perspective. I wanted to wear their shoes and see the SDLC from their eyes. I also thought that it would help me groom myself better as an all-round IT professional.

Six Agile Team Behaviors to Consider

Are members of agile teams different from members of other teams? Both yes and no. Yes, because some of the behaviors we observe in agile teams are more distinct than in non-agile teams. And no, because we are talking about individuals!
