If you run a website, even the smallest issues can be frustrating. Finding and fixing those bugs is often challenging. But while they may seem minor, small website glitches that lead your visitors to have an unsatisfying experience can seriously impact your business growth.

Many types of bugs can affect your websites, such as SEO-oriented bugs, functionality-related bugs, and stuff like broken links and images. Some of these are easy to fix, but others are challenging to find and fix.

So, how do you find bugs in your website and fix them?

In this blog, we’ll look at how you can find bugs on your website with ease and fix them. 

Why is bug tracking important?

Even the most experienced software developers are estimated to make 100 to 150 errors for every thousand lines of code. The CISQ report states that even a small fraction of coding errors – like 10 percent – can significantly impact the quality of an application. For example, a 20,000-line application with 200 serious coding errors is relatively small.

Bug tracking allows you to: 

  • Identify bugs more easily 
  • Prioritize bug fixes 
  • Track the progress of bug fixes 
  • Keep records of all bugs reported in your software

Yvette Francino, an Agile consultant, says that defect tracking is essential to ensure that identified system bugs are actually fixed. Tracking tools provide guaranteed follow-through and offer valuable metrics.

Your team can link any faults to updated code, tests, and other data, depending on the tool you’re using, enabling traceability or a thorough investigation of various defect trends. It could be time to review and rewrite a module if it has an unusually high number of flaws.

Testing should be completed quickly when bugs are simpler and less expensive to fix. An IBM study discovered that fixing flaws found after the fact, or after the product has been released, might cost up to 15 times as much.

Recently, a technique called continuous testing has been employed by many teams. Quality testing and feedback are performed in this kind of scenario at every level of development, from concept to coding to deployment. By identifying and analyzing flaws early in the product cycle, contemporary technology, such as artificial intelligence, can also contribute to the testing process.

Bug testing checklist for your website

1. Mobile testing

As the number of mobile devices and platforms continues to grow, it’s more important than ever to make sure your website is compatible with as many of them as possible. Mobile testing is the process of testing your website on different mobile devices to ensure that it works correctly and looks great on all of them.

There are a few different ways to approach mobile testing. One is to use a mobile device emulator, a software program that simulates a mobile device. This can help with basic testing functionality, but it doesn’t give you an accurate picture of how your website will look and work on an actual device.

Another option is to use an actual device, which is the most accurate test method. However, this can be expensive and time-consuming, as you need to test on as many different devices and platforms as possible.

The best approach is to use a combination of both emulator and real device testing. This way, you can get the best of both worlds – accuracy and speed.

2. Accessibility testing 

Accessibility testing is the process of testing to ensure that a product or service is accessible to all users, including those with disabilities. This can include testing for compliance with accessibility standards, such as the Web Content Accessibility Guidelines (WCAG), and testing to ensure that the product or service is usable by people with disabilities.

Many areas need to be tested when carrying out accessibility testing, including:

  • Text size – Anything displayed on the screen is large enough for people with visual impairments to read comfortably.
  • Colour contrast – There is enough contrast between text and background color so that text can be read easily by people with visual impairments or color blindness.
  • Contrast ratio –There is enough difference between dark colors (text) and light colors (background) so that text can be read easily by people with visual impairments or color blindness.
  • General HTML & CSS checking 

3. General HTML & CSS checking

HTML and CSS are the bedrock technologies of the internet as we know it. As such, it’s critical that any bug testing include checking for errors in both HTML and CSS.

HTML error checking

There are a few things to keep in mind when checking your HTML and CSS code for errors: 

  • First, make sure that you have a validator tool set up and running. This will help you identify any syntax errors in your code. 
  • Second, take the time to test your code in all browsers and on all devices. This will ensure that your code is cross-platform compatible. 
  • Finally, be sure to check your code for any potential security vulnerabilities. A good way to do this is to use a static code analysis tool.

4. Performance testing

Performance testing is a type of bug testing that assesses how well a website or application performs under various conditions. This can include load testing, which measures how well the site or app performs when there is a high traffic volume, or stress testing, which assesses how well the site or app performs when it is under a lot of stress.

Performance testing can include:

  • Software: The server, database, and application code.
  • Hardware: Servers, network infrastructure, and storage.
  • Connectivity: Internet connection speed, latency, and packet loss.

Performance testing is important because it can help identify potential problems with a website or app before it goes live and can help ensure that it can handle the traffic and stress it will experience once it is live.

Here’s an overview of standard performance testing techniques:

  • Use an emulator – Emulators are software programs that simulate real-world conditions, like a browser running on a mobile device or tablet. They allow you to test your website’s performance on various devices and browsers without buying them all.
  • See how code affects performance – Sometimes, there are ways to reduce the amount of code used on your site without sacrificing functionality — like using CSS sprites or minifying JavaScript files — which can improve page load times significantly.
  • Stress testing – To make sure your website is running smoothly, calculate the number of visitors and track how your website performs under different loads. If your website crashes when too many users login simultaneously, you need to identify the cause of the problem and fix it.

5. Security testing

With so many websites on the internet, it has become a common hunting ground for hackers looking for their next target. Hackers can intimidate website owners with their sophisticated methods of stealing or taking control of crucial data. Some examples include:

  • Cross-site scripting (XSS) attacks – where malicious code is injected into a website to steal information or cause damage
  • SQL injections – where a hacker inserts SQL commands into an application’s database query, which can be used to extract data from the database or even execute commands on the database server itself
  • Brute-force attacks – where an attacker tries all possible passwords until they find one that works

Security testing is a critical component of any bug-testing strategy. By testing for security vulnerabilities, you can help ensure that your software is not susceptible to attack. 

While it may seem daunting, there are steps you can take to protect your website from these virtual criminals. Taking proactive measures and staying informed can help keep your website safe from attack.

When you perform security testing, it is important to remember a few key points. 

  • Always store information securely using a trusted method of storing data, such as a secure server or encrypted database. 
  • Use two-factor authentication for any sensitive information to add an extra layer of security and helps to ensure that only authorized users can access the data. 
  • Moderate comments on your content to prevent any malicious comments from being posted and will also give you a chance to flag any potential security issues.

6. Beta testing 

Beta testing is the process of evaluating a product by testing it on a group of people who are representative of your target audience. Beta testing aims to show that the product is ready for release.

The key to success in beta testing is to have a well-defined set of objectives and a plan for achieving those objectives. 

Web app beta testing

Here are some things you should know to carry out an effective beta test program:

  • Use your mistakes as learning opportunities! By documenting them, you can write better test cases in the future and avoid making the same errors.
  • Share the results of your work with your team as soon as possible. Use video feedback to make sure the team understands it the best way possible. Also, use communication tools such as slack and zoom so that teams stay connected with each other. 
  • Quickly debug any errors you may come across and prioritize what needs to be fixed immediately and what can wait. By staying on top of things, you can nip any potential problems in the bud before they have a chance to spiral out of control.
  • Before and after conducting beta tests on your website, you must provide clear instructions to your testers. This includes what you want them to test for and how you want them to do it.

7. Cross-browser testing

Cross-browser testing is the process of testing how your website or web application looks and behaves across different browsers. 

Cross-browser testing

It’s important to perform cross-browser testing because: 

  • Different browsers render web pages differently, so you want to ensure that your site looks and works how you want it to, regardless of which browser your users use. 
  • Browsers have different levels of support for web standards, so cross-browser testing can help ensure that your site complies with the latest standards.

There are a few different ways to carry out cross-browser testing. One is to use a web-based testing service that provides access to various browsers and devices. Another is to install different browsers on your computer and test your site or app in each one.

Whichever method you choose, it’s important to test your site or app in as many different browsers and devices as possible. This will help you identify browser-specific issues and ensure that your site or app works correctly for all users.
