The test design specification is a document that defines test conditions, a detailed test approach, and high-level test cases associated with a test item. It determines which test suites and test cases to run and which to skip.

Using test design specifications, you can simplify your understanding of the current testing cycles. Simple questions like "What are we doing?", "How are we doing?" and "Why are we doing this?" are all answered in this document. However, to achieve the result, many things must flow correctly in creating specifications to make perfect sense.

When we think about the idea of an application, one central question constantly trembles: What would be the best platform to develop it for initially? The reason for this question is the highly fragmented market today we live in.

Currently, a user has two primary options to operate an application. For example, a ticket booking application can either be opened as a web application on a desktop or a mobile device can be considered for the same process. Users can also download the mobile application if they choose a mobile device. After this, these options divide further. Let’s say they prefer a mobile device to download the application. But then, which operating system are they using? Since Android and iOS have APIs and structure that is poles apart, they need separate applications.

“When Vue’s user count reached a certain volume, it became a community. Suddenly all these people counted on me: contributors, users, educators, students… It became bigger than I ever thought it could be.” – Evan You.

This is a confession of a developer towards releasing a JS framework in 2014 that today is used by over 1.5 million users. A framework has become significant in website development if we consider how new it is. With developers picking up Vue slowly, the question of Vue.js testing becomes all the more interesting to decode among the organization.

With the exponential growth in digitalization worldwide, organizations hold a large amount of data today. This data can be extracted, cleaned, and used to reveal analytics that was not possible earlier. One can use these numbers to expand web applications, analyze user patterns, and present exactly what they want to see to the user. This can only be unlocked by using an appropriate tool to capture this data and determine usage patterns.

Not only this, but if something is wrong, the tool should be able to identify it and provide solutions that can run the application in the optimum desired space. This hectic work starts after deploying the web application and is as crucial as development because it can take the business down very quickly.

“A small group of developers and I gathered to design and build a new internal tool and saw an opportunity to do more. We saw ourselves building something more substantial than another internal tool through that process. Months later, we ended up with an early version of Bootstrap to document and share common design patterns and assets within the company.”

The above statement was said by Mark Otto, one of the developers of Bootstrap. Jacob Thornton, another developer, and they both worked in the Twitter organization, which is a popular social media website. However, even though we see a beautiful landscape as an end-user, the story differs for the developers responsible for building it. A website accessed by millions of people every day had to be (or needed to be) just perfect for each.

The integral part of web development is cascading style sheets, which are popularly called CSS. The library contains a long list of functions and properties that help us develop functionalities in a couple of lines rather than writing messy JS code. This may include position sticky, media queries, or setting up the aspect ratio for the web page.

In my web dev experience, I always divided the functions and properties available in CSS into two partitions. One section contains easy out specific design-related items in web development, such as sticking an element to the top while the user scrolls. The other section contains better efficiency, optimization, and improvement of the development strategies according to the latest web development trends.

The pandemic of 2019-2020 made us all lazy. With no option but to sit at home, 35.82% of us gained weight in that phase, thanks to our laziness. Fortunately, that phase gives us an excellent chance to understand a somewhat similar concept in web development. So, how do you define the term “lazy”? While Google says, “Unwilling to work,” I can rephrase it to “not willing to work until necessary.” Until it is extremely necessary for a lazy person to move to another place than that lousy couch, they will stick to it.

Similarly, in CSS, we call lazy images those images that are not willing to be fetched from the server to the client (from couch to the place X in our analogy) until it’s extremely necessary. Lazy images will serve as the center point of this blog. The post will revolve around encouraging the developers to make more and more images lazy in contrast to real life. The main attractions that will throw a bit of light on what these lazy load images are, how to lazy load images, as well as the ways in which a developer can convert an image to lazy.
