It is important that web applications are optimized to ensure the best application performance for the end user. PHP developers can improve website performance by load testing their PHP website. Load testing checks the rigidity, speed, interoperability of the system, and the performance and the reliability of a PHP website.

Website load testing services determine how websites deal with online traffic. Too often, people equate it with performance testing. However, load testing is just a type of website performance testing. Other types of performance testing include endurance testing, volume testing, scalability testing, spike testing, and stress testing. In website deployment, it is common that transactions may fail and systems crash. It is due to concurrent demands on the website and adjustment over resources.

When we decided to build Checkly's browser checks, we chose to do so with Puppeteer, an open-source headless browser automation tool, later adding Playwright, too. We wanted to support users with synthetic monitoring and testing to let them know whether their websites worked as expected at any given moment. Speed was a primary concern in our case. Yet, determining which automation tool is generally faster is far from simple.

Software testing methods are essential in building software. It helps developers deal with different types of bugs. As we all know, these bugs may range from a missing semicolon to a critical business requirement. Thus, software testing becomes an essential part of a test driven development environment. We are in the era of process automation. Today, businesses are dependent on one or more software products. Therefore, software quality becomes crucial.

All developers have seen them, even in well-structured Golang programs: comments suggesting you keep away from lines of code since they seem to be working in a magic way. These warnings make us timid, fearing we might break something. But applications need to change, to improve and innovate. That’s why unit tests are a vital part of software development. They help developers know whether the small parts of their software perform their intended function correctly.

Have you ever wondered how many active users your application can handle at the same time? If so, you’re not alone. Here at Mattermost, we’re building a highly concurrent messaging platform for team collaboration that needs to potentially serve up to several thousands of users simultaneously.
