How to test a website: A short guide



How to test a website: A short guide

People are spending more and more time on the internet today. The website ecosystem is enormous and it keeps growing steadily. According to Statista, there were 238 million websites in 2009, 969 million in 2014 and more than 1 700 million websites in 2019 online globally and today there are many more Internet users. With such a level of competition, launching a successful site seems to be challenging.

Obviously, the main goal of every website owner is to give a certain value to the visitor: useful content for reading, a functional web service, a physical or digital product for purchase, viewing a news feed, and any other purpose for which a visitor enters the internet. This is the exact reason why software testers are needed. Professional testers ready to check a website for any flaws, including poor user experiences. The next question is how to test a website the right way? Is it possible to do this on your own? How many testers do I need to test my site? Such a mass of questions arises for any site administrator and business owner on the Internet. But the answer cannot be unambiguous for different cases, so the TestFort full-cycle software testing team is ready to provide consulting to everyone who wants to understand testing and eliminate errors even before launching your project. Here’s the list of the important testing techniques that will help any website owner to win a myriad of customers online.

Website functionality testing

One of the most important aspects of website QA testing is functionality. Each page of your site must work properly, regardless of the operating system or the device a visitor uses. Functional tests also show whether all functions of the site work in accordance with the established requirements. The functionality testing, in particular, includes links testing, website forms testing, cookies testing and HTML/CSS check.

Usability testing

Is it convenient for users to interact with your website? You can learn that through usability testing easily. These tests help to verify the efficiency of every attribute on the site the visitors use, such as menus, navigation bars, images, videos, text content, buttons, forms, links, and so on. Usability testing reveals whether the website pages, buttons, fields are easy to use, whether there are any types of errors and is your content well-structured, informative and logically linked.

UI testing

UI tests show whether the graphical user interface contains the required functionalities and whether all specifications are met. With UI tests, you also check the design elements such as layout, colors, fonts, font sizes, labels, text fields, text formatting, labels, buttons, lists, symbols, links, and the associated content. While performing the UI tests it is necessary to test the website on different types of devices, different screen resolutions as well as to check the accuracy of UI elements on localized versions. UI test processes can include both automated website testing and manual website testing procedures.

Performance testing

The term “performance testing” is basically used to summarize any type of software test that verifies the site responsiveness, scalability, stability, reliability, and speed under different circumstances. There are several types of performance tests including stress tests (to check how the site works beyond the limits of its expected workload), load tests (how the site works when the workload increases), stability tests (to check the ability of the site to work well over a long period of time), volume tests (to check the site behavior when the data volume increases), load speed testing, concurrency tests (to identify what happens when multiple visitors are active on your website).

Security testing

The security of your site counts for a lot. If third parties get access to your data it may lead to site failures, sales losses and what is even more important – to the loss of trust. In order to prevent such scenarios, security tests are performed (in particular penetration and vulnerability testing). Those tests are aimed at ensuring that: the access to the data by an unauthorized individual is impossible, the inactive sessions are killed, SSL security functions well, captcha works correctly, restricted files cannot be downloaded without permission, and no one can log into your site with the wrong username or password.

Beta testing

Before the big launch, it is always better to test your website in a real-world environment. With real users being involved, beta testing helps you to get many useful insights, eliminate the bugs and improve your website significantly.



What Are the Different Types of Water Heaters That Exist Today?



What Are the Different Types of Water Heaters That Exist Today?

Did you know that water heating accounts for as much as 20% of your household energy use? And that figure grows the longer you stay in that nice hot shower!

Of course, the types of water heaters you choose can also increase (or reduce) your that figure. Once upon a time, people just had a simple hot water tank heated by a fuel of some kind. Today, there’s a surprisingly extensive range of water heaters to choose from, and knowing which is best for your home can be daunting.

If you’re upgrading your current heater or choosing appliances for a new build, diving into the pros and cons of each machine is essential. Below, we explore it all. So read on!

What Is a Water Heater?

Before you can find the best water heater for your home, you need to understand what a water heater is and does!

Believe it or not, but the is right there in the name: a water heater is an appliance that heats the water in your home, which you then use to wash dishes, clean your body, and wash your clothes–among other activities.

Before the 1890s or so, Americans had to heat their water in an enormous metal bucket atop their wood-burning stoves. Then, they’d carry it over, bucket by bucket, to fill a bathtub in the kitchen.

Today, we’re far luckier–we have water heaters and indoor plumbing to do the job for us.

How a Water Heater Works

Now we’ve cleared that up, let’s explore how a residential water heater does what it does. While there are many types of water heaters (more on those later), they all work in similar ways.

First, water is fed into a tank or runs through a pipe. Then, the water is heated slowly (in the case of the tank) or rapidly (in the case of the pipe) until it reaches a pre-determined temperature. Then, when you turn on the hot tap anywhere in your home, the water leaves the tank or runs through the pipes, arriving in the sink or shower hot.

Water heaters mostly used to function on electricity, but now you can run water heaters on gas, solar, and even the hot air from your attic!

If you need a water heater replacement, that’s usually a plumber’s job. But, unfortunately, it’s also typically a significant expense!

Types of Water Heaters: Explained

Let’s say your current water heater has broken down, and you’re in the market for a new one. If you’re a smart homeowner, you’ll look into all the standard options available today rather than just buying a replica of what you already had.


Almost every homeowner will be familiar with a conventional or tank-style water heater when it comes to homeownership. If you didn’t have one in the house you bought, you almost certainly grew up with one in the house.

This water heater has a tank that fills with water. The tank has two valves:

  • A temperature control valve, which releases at 120 F
  • A pressure control valve, which releases at 150 PSI

The water in the tank is constantly re-heated to stay at the desired temperature. Then, the hot water is piped all over the house as needed.

Tank water heaters come in various capacities depending on your budget, how it’s powered, and the size of your home (namely, how many places in your house need hot water).


Some homes (especially new homes) have a tankless water heater installed.

As soon as you turn on the hot tap, the coils in the water heater are filled with water. Next, an element heats the coils, which heats the water. It’s the instantaneous result that people love about these water heaters.

In most cases, this type of heater is powered by gas. If they’re run on electricity, they might not be as efficient and may raise your utility bills more than you’d like.

Tankless water heaters are great for homes using a small amount of hot water, like condos or apartments. However, larger homes requiring larger volumes of water might get tepid rather than hot water coming out of the tap.

They also require a certain level of water pressure to function effectively.

Hybrid or Heat Pump

If you’re looking for ways to lower your utility bills (and who isn’t these days), consider a hybrid water heater.

This type of heater uses the heat from the ground and the air to heat water. It only uses electricity to transfer the heat to the water, rather than using it to heat the water itself, saving energy.

This type of water heater is typically quite significant because it features a pump on the top of the appliance. This means you need a decent amount of ceiling clearance to install it in your home.

And while it’s relatively inexpensive to run and easy to maintain, it has a higher upfront cost than most other types of water heaters.


A water heater option to emerge in the past decade or so is the solar-power water heater. This option is excellent for those considering adding solar panels to their home and perfect for anyone who already has them!

You need to connect your water tank to solar panels installed on your roof to get hot water. The energy from the sun is transferred to the tank via a closed-loop system made of heat-conductive material. It’s this that heats the water in the tank.

Just remember that while solar is beneficial (and cost-saving) in most parts of America, areas with low sunlight hours might not get the return on investment they were expecting.

Get the Steamy Bathroom of Your Dreams

Whether you’re happy to stay on the grid or excited to embrace the eco-friendly age, there are types of water heaters to suit.

Environmentalists can choose between solar-powered water heaters and heat-pump or hybrid options. Traditionalists or those in areas with low sunlight hours can stick with a conventional water heater or go for a tankless model. What’s essential is that you do your research on how each option meets your needs and shop around for the best prices.
