25 Web Dev & QA Testing Statistics Every Developer Should Know 
Trends move quickly in the web development and QA testing space. These trends can help predict where the QA and testing industry is headed. Development teams can adapt emerging best practices and methodologies while gaining a better understanding of the challenges they face throughout the development cycle.
General Web Dev & Design Statistics
The state of web development and web design remains consumer-focused. Data suggests that customers prefer websites and software with greater usability. As such, web developers, designers, and testers are encouraged to focus on creating a great user experience — images, graphics, and videos are especially important. Fast loading times are also crucial to a website’s success.
1. 48% of people look at a website’s design to gauge a business’ credibility. (Blue Corona)
Good website design is hard to ignore, and audiences use it to decide if they want to do business with a company or not. As such, a user-friendly and functional website is critical in attracting new clients. Development teams around the world should keep this in mind if they want to make a great first impression using the sites they create.
2. 250,000+ websites are created every day. (Siteefy)
Thousands of websites are created daily, but not all of these stay active for a long time. Some of them vanish from the internet quickly, while others are created to compensate for the disappearing ones. For a business to stand apart from these websites, it must ensure good functionality and work to keep its presence online.
3. Retailers lose $2.6 billion each year due to slow-loading websites. (Inside Design)
People hate slow-loading websites. Period. Even with excellent web designs, businesses may lose a huge chunk of their sales potential because of those extra seconds in loading time. Slow loading times are often caused by network congestion, bandwidth throttling, and content filtering, among others. Properly testing the site and following page speed best practices are important to solving these issues.
4. Photos and images (40%), color (39%), and videos (21%) are the top visual elements people appreciate about a website. (TopDesignFirms)
Consumers shy away from websites with poor design and speed, but they appreciate websites that have excellent images, colors, and videos. Consistent and on-brand design without bugs or glitches is key to retaining their attention.
5. 60% of customers say website usability is important for them in an online shop. (Statista)
Improving the usability of your website or shop can attract more customers. You can do this by making the site as easy to use as possible through visual hierarchy, consistency, and colors. Usability tests are important for this, along with other types of tests.

Bugs & Testing Stats You Should Know
The testing market is expected to grow into 2030 as cybersecurity and risk compliance underpin the demand for various forms of testing. Websites and mobile apps are particularly in need of fast, efficient, and effective testing.
Meanwhile, the QA teams and testers themselves also face challenges. These challenges are related to the cost, speed, and scalability of their testing efforts. Generally, more and more companies are seeking to replace their testing efforts with automated procedures.
6. The software testing market is expected to grow by more than 6%. (GMI)
In 2021, the software testing market crossed above $40 billion. Experts expect it to have a CAGR of over 6% from 2022 to 2030.
7. 79% of users note bugs in their software and websites. (PractiTest)
Companies use bug reports as the most common type of test documentation. Around 79% of end users noted they encountered bugs in 2019.
8. 69% of companies say developers should be able to write secure code. (GitHub)
Security is a major concern among developers. Around 69% of companies require developers to write secure code. However, 68% believe that lower than 50% of developers can’t spot vulnerable parts of code. These vulnerabilities are usually found later on.
9. Cybersecurity spending is expected to hit $133.7 billion in 2022. (University of North Dakota)
Data breaches and the constant threat of security systems failure have increased demand for cybersecurity and risk compliance. Websites and software programs must be tested frequently against new threats. Mobile apps are also an important field for the testing industry, as the mobile app market is expected to reach $407.31 billion by 2026. These demands underpin the market for testing services.
Manual vs. Automated Testing Statistics Dev Teams Should Know
Development teams face many challenges in terms of implementing the testing cycle. They use a variety of approaches with varying levels of success. Other issues include implementing cost- and time-effective approaches. This section revolves around manual and automated testing statistics, along with the tools developers often use.
10. 77% of testers work on web testing. (The QA Lead)
Most testing happens during the web development cycle. However, the same data suggests that 74% of testers do other work apart from testing — up to 57% also do scripting, automation, and data management tests.
11. 48% of QA teams have between one to five members. (The QA Lead)
Nearly 50% of companies have QA teams with one to five members. Meanwhile, 24% of testing teams have six to 15 testers. QA and quality control teams collaborate. Despite having different tasks, the two teams are tightly connected.
12. 35% of companies use non-testers in their testing process. (PractiTest)
Around 35% of businesses involve non-testers in their testing cycle. However, 55% of companies still use testers for the majority of their testing needs.
13. High-performing products have 200x more frequent code deployments. (Puppet)
According to Puppet’s 2016 State of DevOps Report, high-performing product teams perform better than others because they deploy 200 times more frequently. They also have 2,555 times faster lead times and recover 24 times faster, with three times lower change failure rates.
14. 44% of testing teams find project participation “very challenging”. (PractiTest)
