Top 10 Types Of Software Testing Bugs You Should Know

One of the most underrated, yet required positions on any development team is a software tester. This is the person we send into the trenches to not just find the broken parts of our codes, but to break our flow. The type of data a software tester can provide you is gold. With it, you can optimize your application, improve user engagement, close out any security flaws and more. In this article, we will be talking about the top 10 software testing bugs every tester and you should know.

Before we begin let’s get on the same page on what a software bug is – think of it as a flaw and/or failure in the logic of your system that creates an unexpected result. So basically, you click a button and it should trigger a pop-up but instead crashes the website – this is a bug.

Top 10 Types Of Software Testing Bugs You Should Know

1. Functionality Errors In Your Software

Much like the example above, you have created a function. In very simple terms, think of this is a clickable button. When a user clicks this button an error in the logic you coded. Often times with buttons the error is non-clickable. Functionality errors are all about how the code should act.

Best way to convey these errors to your team is through video. This allows the team to really understand what is going on here. As a side note, The Bug Squasher does have a video recorder within it helping you capture these errors quickly.

2. Authentication Fields Errors And Solutions

We all know mobile apps are no longer the future but the present. It’s a market that is hungry for talented developers. However, you’d be surprised how common authentication field errors are when launching new apps.

An authentication field error has to do with a small hiccup on development. When users sign up for your app, form, whatever, they provide data. It is always best practice to set a limit in the number of characters allowed for this ie. limits on phone number, state, city, etc.

Typically, this error is triggered when that rule is not in place and the user provides a huge character count of data making the app unable to authenticate the fields. It’s such a small bug, that can cost you so much data.

3. Be On The Lookout For Calculation Errors

During the testing stage, if you have any type of cart action ie adding products, math is involved you want to make sure you test for calculation errors. This is another small misstep that can cost you big time.

Typically this error happens because of incorrect formula, data isn’t matching, bad logic, and coding errors. We strongly recommend making sure to go through any process (normally this is the checkout process) and confirm the calculations are accurate.

4. Make Sure To Test Your App On Different Screen Sizes

Our team works in MACs. We build for our apps for MACs. We debug in MACs. At the end of every project, we go back and check the app in different screen sizes and devices. In a world where everything is pushing to be mobile friendly first, it’s no surprise errors come up.

We recommend doing some research and identify what browsers and devices your audience typically uses. Once you have that idea, check your software within them. Normal bugs you will see often have to do with screen resolutions not being properly defined on different devices and browsers.

5. Test For Errors Handling Errors

I remember pulling my hair out when I would jump online ten years ago and I would get an error message saying, “There is an error, please close and try again.” What am I supposed to do with that? Where do I go for support with that? How do I debug that?

The problem is error handling errors are so common it is maddening. The error message gives no hint whatsoever what the actual error is making it a huge waste of time.

Our recommendation – The Bug Squasher shines here. When you report a bug, you are given a bug report that outlines console errors, the users’ browser, device and more. This is how you manage bugs properly. You give an overview of the error to review what the next steps should be.

6. Don’t Forget About Syntactic Errors

We are all human, mistakes happen. Syntactic errors are one of these most common errors when launching a new project. To be clear, we aren’t talking about an error within the code. We’re talking about spelling and grammar issues that are on the frontend of your website.

A recommendation for this, take all your copy and run it through a grammar tester. Do this at different stages of development. Before going live have two or three different people look over the site copy. Let them read through it and bring to your attention any funky sentences and/or typos.

7. You May Have Control Flow Errors

A control flow error within software causes a bug in what action and/or condition should be triggered next.

To keep this basic, think of how forms normally work. A user fills out fields, selects save and close. Pretty standard workflow. If during the process the user selects close and nothing happens this is a control flow error.

We recommend conditions that require multiple steps be tested multiple times to ensure it’s function is working properly.

8. Design Bugs Within Your Software

A great design can take your product to the next level – a poor one will never let you reach the next step of production. Every software application has a growth period in design where it starts off looking one way and evolves.

When it comes to website bugs within your software, sometimes a common bug is actually a design issue. Usually, this happens when a design is provided in the wrong specs making it difficult for the developer to code. Also, if there are too many designers this can be an issue. Ie. designer one creates one layout with a set of expectations for users and designer two overwrites that.

Design is a huge error your software tester should actively be addressing. Not only will it impact code, but it will also reach your users.

9. Third Party Bugs

You ever feel like the problem is not you, but someone else? Well, you may be right. Let’s look at WordPress as an example. WordPress is one of the most popular frameworks on the internet. There is so much information on the tools on the platform you can’t go wrong. The problem is, WordPress is known for having major security issues.

There are so many plugins being created that you can access. Not all plugins are kept up to date – this not only creates serious security issues but also can lead to website bugs.

During your software testing make sure if you are using any third party tools to really spend some time reviewing them and making sure they are secure and updated regularly.

10. “Not A Feature Yet” Bug

Probably the most exciting part of doing software testing is when you come across a part of your software that really feels like it needs an extra feature.  Something that doesn’t exist, but it feels like it should and could only make the software better.

We refer to these software bugs as, “Not a feature yet bug”. If you haven’t done so already, make sure to have an internal roadmap outlining upcoming features. When these bugs come up – keep them there. Down the road, it may be a pleasant feature to push live.

Final Thoughts…

Having quality assurance and software testers is a must for any project gearing up to upgrade/launch. To ignore software testing is to put your project at a costly risk of failing. Our team lives and dies by web bug reporting. We can’t stress enough how important it is for you to make sure you are testing your software in different ways.
