Mock gRPC Services for Unit Testing

,

In our day-to-day work, we develop applications that include interactions with software components through I/O. They can be a database, a broker, or some form of blob storage. Take, for example, the cloud components you interact with: Azure Storage Queue, SQS, Pub/Sub. The communication with those components usually happens with an SDK.

From the start, testing will kick in. Therefore, the interaction with those components should be tackled in a testing context. An approach is to use installations (or simulators) of those components and have the code interacting with an actual instance, just like the way it can be achieved by using test containers or by creating infrastructure for testing purposes only.
Another approach is to spin up a mock service of the components and have the tests interacting with it. A good example of this can be Hoverfly. A simulated HTTP service is run during testing and test cases interact with it.

OTT Application Testing: What It Is and Why You Can’t Do Without It

,

Over two years ago, the COVID-19 pandemic completely changed the business landscape for dozens of industries. For example, the eCommerce industry saw a meteoric rise, while cinemas and theatres have not yet fully recovered from the multiple nationwide lockdowns.

One of the industries whose rapid growth was also triggered by the coronavirus pandemic is the OTT or Over-the-Top industry. For millions of people stuck at home for months on end, with little to no social interaction, OTT services have become the go-to entertainment channel. Subsequently, the number of available streaming services also skyrocketed, and new players are regularly unveiled.

Different Test Scopes in Rust

,

I’m still working on learning Rust. Beyond syntax, learning a language requires familiarizing oneself with its idioms and ecosystem. I’m at a point where I want to explore testing in Rust.

The Initial Problem

We have used Dependency Injection a lot – for ages on the JVM. Even if you’re not using a framework, Dependency Injection helps decouple components. Here’s a basic example:

Exciting New Features in Safari 16

,

Apple has released an OS update. Packaged in with it is the latest version of Safari, 16.

Expected to be released ahead of next month’s macOS 13, Safari 16 is packed with updates, making it one of the most capable browsers available.

For web designers, the significance is the forward momentum in web technologies that enable freer design work and fewer hacks to achieve complex layouts. Little by little, CSS recommendations are being implemented to the point that using JavaScript for layout is rapidly becoming as unnecessary as it is disliked.

Some of this was announced in June in the Safari 16 beta. But a lot has been added in the last couple of months. So here’s what’s new in Safari 16 today.

CSS Container Queries

The most exciting addition to Safari 16 is CSS Container Queries.

It is hard to understate how in-demand this feature has been; if you imagine an edit button on Twitter that gifted you crypto every time you corrected a typo, you’d be getting close to how popular this feature is.

Until now, media queries have detected the whole viewport. And so, if you have an element like a card, for example, that needs to change at smaller viewports, you need to calculate the available space and adapt the element’s design accordingly. Unfortunately, this frequently gets out of sync with edge cases causing more than a few headaches for front-end developers.

Media queries are severely restrictive to modern layout methods like Grid that wrap elements automatically because there is no way to detect how the elements are laid out.

Container Queries solve this by allowing you to define styles based on the size of the actual containing element; if a div is 300px wide, the contents can have one design, and if it’s 400px wide, they can have a different design—all without caring what size the whole viewport is.

This is dangerously close to OOP (Object Orientated Programming) principles and almost elevates CSS to an actual programming language. (All we need is conditional logic, and we’re there.)

The latest versions of Chrome, Edge, and now Safari (including mobile) support CSS Grid. Even discounting the rapid decline of Twitter, this is way more exciting than any edit button.

CSS Subgrid

Speaking of Grid, if you’ve built a site with it (and if you haven’t, where have you been?), you’ll know that matching elements in complex HTML structures often results in nesting grids. Matching those grids requires careful management, CSS variables, or both. With CSS Subgrid, grids can inherit grid definitions from a grid defined higher up the hierarchy.

CSS Subgrid has been supported by Firefox for a while but is not yet part of Chrome or Edge. Until there’s wider support, it’s not a practical solution, and using a fallback negates any benefit of using Subgrid. However, its introduction in Safari will surely herald rapid adoption by Google and Microsoft and moves the web forward considerably.

CSS Subgrid is likely to be a practical solution within 18 months.

AVIF Support

AVIF is an exceptionally compact image format that beats even WebP in many instances. It even allows for sequences, creating what is essentially an animated GIF but smaller, and for bitmaps.

AVIF is already supported by Chrome, with partial support in Firefox. Safari now joins them.

AVIF support is one of the more valuable additions to Safari 16 because you’re probably already serving different images inside a picture element. If so, your Safari 16 users will begin receiving a smaller payload automatically, speeding up your site and boosting UX and SEO.

Enhanced Animation

Safari 16 introduces some significant improvements in animation, but the one that catches the eye is that you can now animate CSS Grid.

Yes, let that sink in. Combine Container Queries and animation. The possibilities for hover states on elements are tantalizing.

Safari 16 also supports CSS Offset Path — known initially as CSS Motion Path — which allows you to animate elements along any defined path. This enables the kind of animated effect that previously needed JavaScript (or Flash!) to accomplish.

Chrome, Edge, and Firefox all support CSS Offset Path; the addition of Safari means it’s now a practical solution that can be deployed in the wild.

Web Inspector Extensions

Announced as part of the beta release, Web Inspector Extensions allow web developers to create extensions for Safari, just as they would for Chrome.

Web Inspector Extensions — or Safari Extensions as they’re destined to be known — can be built in HTML, CSS, and JS, so the learning curve is shallow. It’s a good route into app development for web designers.

Because the underlying technology is the same as other browser extensions, anyone who has made a Chrome, Edge, or Firefox extension will be able to port it to Safari 16+ relatively easily. As a result, there should be a rapid expansion of the available extensions.

Improved Accessibility

Accessibility is key to an effective and inclusive web. Be like Bosch: everybody counts, or nobody counts.

When testing a design for accessibility, emulators don’t cut it. In my experience, Safari has some of the most reliable accessibility settings, especially when it comes to Media Queries like prefers-reduced-movement.

Further gains in this field mean that Safari continues to be an essential tool for QA tests.

Reduced Resets

Finally, I want to throw up my hands to celebrate the reduced number of non-standard CSS appearance settings.

For years we’ve been prefacing our style sheets with elaborate resets like Normalize, designed to undo all the assumptions browser developers make about design and the UI preferences of their engineers.

Safari 16 has reportedly “Removed most non-standard CSS appearance values.” How effective this is and how much we can rely on it given the other browsers on the market remains to be seen. However, like many of Safari 16’s changes, it’s a step towards a browser that’s on the developers’ side instead of an obstacle to overcome.

What Customer-First Web Design Looks Like

,

The purpose of a website is to reach new customers and keep current ones engaged. Therefore, customer-first should be at the top of your list for design features. After all, without your clients, your business won’t grow or succeed.

Customer-first has been a buzzword for a few years now. In a nutshell, it’s easy to imagine what customer-first design means. The needs of consumers come before anything else. However, the concept isn’t quite as simple in practice. A lot of nuances enter the equation.

Just what does it mean to have a customer-first web design? What are the must-haves to reach users on their level and keep their attention for the long haul?

Embracing quality customer experiences has driven loyalty for as long as anyone can remember. However, we now live in a time of uncertainty, and when people leave companies on a dime if they’re dissatisfied with any aspect. So you must hit the high notes on every song – your website is your purest online persona and must engage users and keep them entertained.

Whether you embrace causes that matter to your customers and share information on them or tweak your design to meet accessibility guidelines, many factors come into play with a customer-centric design.

In a recent report, researchers found that about 88% of company leaders feel customer engagement impacts revenue. You can’t control every variable, but you can ensure your website hits all the strong points for a customer-first web design that grabs them and keeps them on your page.

Here are our favorite tips to create a customer-first approach. You may already be doing some of these things. Pick and choose what makes the most sense for your business model. Even small changes can have a big impact.

1. Know Your Customers

Before creating a website centered around your customers’ needs, you must know who they are. What are the demographics of your typical clients? Survey them and find out what their needs and expectations are. How can you best help them?

You may also want to survey them about your website. What’s missing that might help them? Is there anything they love? What do they hate? The more you know, the better your design can match their expectations. Create buyer personas based on their preferences.

At the same time, buyers will sometimes say one thing but actually feel another way. No one is quite sure why people do this when being surveyed. One way around that issue is to do some A/B testing to see how they actually feel about various changes. Do they respond the way you thought? What other adjustments need to be made?

2. Find the Right Color Palette

Different industries trend toward various hues. For example, businesses in the banking industry trend toward blues and occasionally reds. Blue elicits trust from users and has a calming effect. On the other hand, the fashion industry might tap into brighter shades, such as lime green. Think about what colors people expect in your industry, and then find your color palette.

Each hue has its emotional impact. For example, red is a color of power and can elicit excitement in the viewer. Choose your shades accordingly to get the most emotional punch possible.

3. Accept Feedback

One of the best ways to improve your site over time to match the needs and preferences of your audience is by allowing feedback. Add reviews, place a feedback form in your footer, and even send out requests for feedback to your mailing list.

It’s also a good idea to find a mentor who has been successful at running a business. Ask them to look at your site and give you advice. You might also enlist the help of a marketing professional.

4. Stick With the Familiar

Have you heard of Jakob’s Law? The rule of thumb states that people prefer common design patterns they’re most familiar with. So when they see a pattern they know, such as a navigation bar layout, it boosts their mood and improves their memory of the site.

When making edits, don’t make significant changes. Instead, implement minor adjustments over time to give your followers a chance to acclimate to the shift.

5. Cut the Clutter

If you want users to feel wowed by your page and engage, you have to limit their choices. Add in too many options, and they may not know where to go first.

Start by choosing an objective for the page. Cut anything that doesn’t point the user toward the goal. Ideally, you’d have a little info, an image, and a call to action (CTA) button. However, this may vary, depending on where your buyer is in the sales funnel and how much information they need to decide to go from browser to customer.

6. Choose Mobile Friendliness

Recent reports indicate about 90% of people use mobile devices to go online at times. With phones gaining greater capabilities and 5G bringing faster speeds to communities, expect people to use their mobile devices even more frequently for internet browsing.

Making sure your site translates well on smaller screens makes sense for your company and for your customers. Be sure to test everything. Click through all links. Fill in forms. Ensure images and text auto-adjust to the correct size, so people don’t have to scroll endlessly.

7. Make Multiple Landing Pages

Like most businesses, you probably have several buyer personas as you segment your audience. Don’t just create a single home page and expect it to fulfill the purpose of every reader. Instead, create unique pages for each persona to best meet their needs.

Make sure each landing page speaks in the natural language patterns of your specific audience. Think about the unique needs of each group. How do their pain points differ? How can you best meet their needs?

8. Keep Important Info Above the Fold

People are busy. They work, have families, and might visit your site on the 15-minute break they get in the afternoon. Most consumers want the information they need to decide and don’t want to dilly-dally around with other things.

Place the essential headlines and info they need above the fold, so they see it first. Make it as readable as possible by using headings and subheadings. Add in a few bullet points. People also absorb information easier in video format, so add a video highlighting your product’s or service’s main benefits.

You should also place a CTA button above the fold if it makes sense for your overall design. Keep in mind people may have visited and already read some of the information. Some users return just to sign up and want to find the CTA quickly.

Step Into Your Customers’ Shoes

Look at your site through the eyes of your audience. What works well? What needs to be adjusted? Over time, you’ll develop a customer-first web design that speaks to those most likely to buy from you. Then, keep making changes and tweaking your site until it hits the perfect balance for your customers.

How to Design an MVP Web Page

,

Learning how to design an MVP webpage or website could be one of the best things you can do as a site creator in today’s digital world.

In a fast-paced landscape, where customer preferences and technology are constantly changing, most companies don’t have time to dedicate months or years to each web project. The longer you take to complete your website, the more likely your creation will be outdated by the time you hit “publish.” That’s why countless creators are beginning to take a different approach.

To avoid wasting time, money, and effort on something that doesn’t deliver a significant return on investment, designers are now building “Minimum Viable Products,” or “MVPs.”

Here’s what you need to know about creating your MVP webpage.

What is MVP Web Design?

Typically, the “MVP” development process is most common in the app or software creation world. It refers to when a developer builds the simplest version of a technology capable of achieving specific goals. For instance, if a company wanted to create an ecommerce app, they would design a simple tool capable of listing products, enabling payments, and tracking orders.

After launching the MVP product, the company or developer would check to ensure it had the right impact on the target market and generated positive results. Using feedback and analytics, the developer would then begin to add new features one at a time.

MVP design aims to ensure you’re developing the best, most valuable product for your audience while getting your solution to market as quickly as possible.

The same strategy in MVP app and software design can also apply to website creation. Rather than building a highly complicated website with multiple features straightaway, the designer would focus on creating a single page equipped with the essential elements.

For instance, instead of building an entire site for your online course, you may develop a single-page website where customers can learn about the system, sign up, and pay for their membership. The great thing about an MVP web page is it allows companies to start advertising their solution, product, or service quickly, with the minimum initial investment.

How to Create an MVP Web Page

Creating an MVP web page is similar to designing any Minimum Viable Product. Throughout the project, the focus will be on keeping the development process simple while collecting as much feedback as possible.

Here’s how you’d get started with an MVP web page.

Step 1: Planning

Planning is an important stage in any web design project. It’s particularly crucial in the MVP landscape, where you need to define the most critical features of your webpage or website to ensure it’s “viable” for your needs. The initial planning stage can sometimes be the lengthiest part of the process, depending on the amount of research you need to do.

For the most part, web designers and companies will begin by conducting market research. This means examining crucial concepts intended to drive your strategy, such as:

  • Your target audience: Who are you trying to target with this web page, and what will they need from your site? A user persona can be helpful if you don’t already have one.
  • Competitors: Who are your main competitors in this space, and what do their web pages offer? Which features do you need to replicate or avoid?
  • Goal setting: What is the main objective of this web page? What do you need it to do, and what might it need to accomplish in the future?

The key to MVP web page planning is ensuring you look holistically at your project without thinking too far ahead. The site you create should be capable of scaling and expanding in the future, but it shouldn’t have too many features from day one.

Step 2: Creating Your Feature List

Once you’ve done your research and formed the foundations of your plan, it’s time to list all the features your MVP web page needs to have. Unfortunately, this is where the process can get a little complicated. It’s easy to start adding capabilities and components that aren’t necessary to make your site more exciting or competitive.

As worrying as it can feel to release a very basic web page, remember your focus is on rapid growth and development. With this in mind, concentrate on narrowing your feature lists down into:

  • Initial must-have capabilities: First, decide what your web page can’t thrive without. If the primary goal of your page is to sell software subscriptions, then you’ll need to implement tools for collecting member information and payments.
  • Next stage functionality: Consider the features you might add once you’ve confirmed your webpage is effective. This will allow you to ensure you’re creating a platform that can expand to suit future needs.
  • Possible future requirements: You can also list features that might be helpful in the future but don’t necessarily need to be implemented immediately. For instance, if you’re selling an online course, you might create a separate page where people can sign up to learn about future lessons.

Step 3: Finding the Right Software

Next, you’ll need to decide how to build your web page. There are several options available to today’s designers. An open-source solution is usually the best route for designers who need to create something specific from scratch. However, if the factor that makes your solution “viable” is unique, you may need access to code to bring your idea to life.

Alternatively, if you’re building a basic webpage capable of something like collecting customer email addresses or facilitating transactions, you might be able to use an off-the-shelf tool. CMS services for web designers can reduce the work and expense involved in creating a minimum viable product.

For instance, you might use a tool like Wix or Squarespace to edit a pre-existing template and simply drag-and-drop the features you need into the right places. On the other hand, if you’re planning on adding more functionality to your site down the line, it’s worth checking if any builder you will use has the right level of flexibility. Many tools will allow you access to code, advanced features, and essential module-based building functions.

Step 4: Implement Your Analytics

One of the essential parts of an MVP workflow is feedback. When you roll out your MVP, you’ll be looking for insights, guidance, and analytics to help you decide what your next steps are going to be. As a result, MVP workflows are based heavily on experimentation.

This means you’re going to need the right analytical tools in place to track crucial information. You can implement tools for collecting customer feedback directly. It’s also worth having a system in place for tracking metrics like:

  • Conversion rate;
  • Traffic numbers;
  • User behavior;
  • Most used/least used features;
  • Technical site performance;
  • Bounce rate;
  • Average time spent on the page.

While Google Analytics is one of the most popular tools for collecting insights in the MVP website design world, various other options are available. You can even find tools with in-built heatmaps to see how people navigate your site more effectively.

It’s also worth having A/B testing components in place. This will allow you to test the different “new” features you add to your web pages over time and examine how they influence your conversions and support your goals. For example, you can use A/B testing to explore the impact of everything from CTA button colors to webpage copy and offers.

Creating Your MVP Web Page

In the fast-paced web development and design world, the old-fashioned and slow approach to designing web pages is growing increasingly less common. Instead, an MVP strategy may be the best bet for companies looking to go to market faster, collect insights from their target audience, and accelerate growth.

Though getting used to this design strategy initially can be challenging, it can save you significant time, resources, and money in the long term.
