Before we discuss Scala testing, let us understand the fundamentals of Scala and how this programming language is a preferred choice for your development requirements.The popularity and usage of Scala are rapidly rising, evident by the ever-increasing open positions for Scala developers.
So, now that the first installment of this two fold article has been published (hence you might have an idea of what Agile Testing is not in my opinion), I’ve started feeling the pressure to explain what Agile Testing actually means to me.
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
As a developer, checking the cross browser compatibility of your CSS properties is of utmost importance when building your website. I have often found myself excited to use a CSS feature only to discover that it’s still not supported on all browsers. Even if it is supported, the feature might be experimental and not work consistently across all browsers. Ask any front-end developer about using a CSS feature whose support is still in the experimental phase in most prominent web browsers. ????
The count of mobile users is on a steep rise. According to the research, by 2025, it is expected to reach 7.49 billion users worldwide. 70% of all US digital media time comes from mobile apps, and to your surprise, the average smartphone owner uses ten apps per day and 30 apps each month.
