Code Intelligence introduces integration of Jazzer.js into Jest

The automated testing platform Code Intelligence recently announced that it has integrated its open-source JavaScript fuzz testing engine, Jazzer.js, into Jest, a unit testing framework for JavaScript.

Jazzer.js is a free, coverage-guided, in-process fuzzer spanning the Node.js platform. It is currently available within JavaScript’s node package manager.

With this, developers can use Jest for both functional and security testing without the need to leave their development environment. 

According to the company, the integration offers developers the ability to run automated security tests that are complementary to their existing unit tests and allows them to test JavaScript applications for hidden bugs.

Code Intelligence also stated that it will be bringing the ability to receive specialized bug detectors for critical vulnerabilities to Jazzer.js. These include remote executions, cross-site-scripting, and injections. 

“While most JavaScript developers already use Jest for functional testing, to test whether their application behaves as expected, our new Jest integration allows developers to also do negative testing. This is to check their applications for unexpected or strange behaviors. It does not only avoid security issues but makes the code more reliable and reduces outages and bad user experience,” said Werner Krahe, product director of Code Intelligence.

The Jest integration enables developers to call Jazzer.js by using the new it.fuzz() function in describe() blocks. 

This function works to call fuzz tests that use coverage feedback to generate several unused and unexpected test inputs that have the ability to trigger security vulnerabilities as well as functional bugs.

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
