Open Source JavaScript Code Analysis

Software Testing Magazine — Mon, 15 Apr 2024 16:00:47 +0000

The quality of the JavaScript code is often verified with the traditional activities of unit and functional testing. There are however tools that allow checking code before or during its execution to assess its quality and its adherence to coding standards using a process called code analysis. This article presents a list of open source tools to perform static and dynamic code analysis on JavaScript programs. If static code analysis can be performed individually on each piece of JavaScript code, modern software development organizations will integrate these tools in their continuous integration or delivery process. This automated approach prevents code that is bad or doesn’t respect the coding standards to reach the production stage. Dynamic code analysis the software when it is performed by executing programs on a real or virtual processor. The two main know open source tools used for JavaScript code analysis are JSLint and JSHint, the second being a fork of the first one. Developed by the famous Douglas Crockford, JSLint can be considered as the main inspiration of the JavaScript open source code analysis tools family. There are however many different tools that try to achieve the same goal and you might find something more suited to your own needs in the list below, especially if you work in specific JavaScript frameworks and contexts like Node.js, Angular, React, Vue, Express or TypeScript. Updates April 2024 * added CallGraph, Tencent CodeAnalyis, Joern, Jsinspect * updated Crawljax (website), Flow (website) * removed Codemodel-Rifle (archived), SourceCodeSniffer (404) March 2023 [...]

End to End Test Automation with Playwright

Software Testing Magazine — Mon, 13 Nov 2023 16:54:19 +0000

You need to make sure that you test complete user flows. With the open source test automation tool Playwright, you can easily in minutes record a test and run that test and visually see what is happening, providing a cool developer experience. Playwright is an open-source automation library for browser testing and web scraping. It was developed by Microsoft and launched in 2020. It provides the ability to automate browser tasks in Chromium, Firefox and WebKit with a single API. This allows developers to create reliable end-to-end automated tests that are capable of running in non-headless mode or headless mode. Playwright supports various programming languages like JavaScript, Python, C# and Java, though its main API was originally written in Node.js. It supports all modern web features including network interception and multiple browser contexts and provides automatic waiting, which reduces the flakiness of tests. This presentation takes a look at how to test across iframes and different browser contexts by testing the user flow of the Stackblitz website, setting up a Vite project in Stackblitz, modifying the code and sharing it, so others can open and interact with it. Let’s get testing with Playwright. Video producer https://viteconf.org/

Full-Circle Testing With Cypress

Software Testing Magazine — Tue, 03 Jan 2023 15:41:17 +0000

Cypress has taken the world by storm by brining an easy-to-use open source tool for end-to-end (E2E) automated testing. Its capabilities have proven to be useful for creating stable tests for frontend applications. But end-to-end testing is just a small part of test automation efforts. What about your API? What about your components? With this talk, you will learn about different types of testing with Cypress and how to test effectively with this open source testing tool. Cypress.io is an open source cross-platform end-to-end test runner for anything that runs in a browser. Its architecture is unique, wherein the tests run alongside the application inside the browser, which allows the tests to closely control and observe the application. This talk will show you how you could start with end-to-end tests using Cypress and then go deeper with component testing and move up to testing our API, circling back to your E2E edge cases. All this will be achieved with a single tool that fits a software developer workflow like a glove. Video producer: https://www.testjssummit.com

This presentation is about the common mistakes that people make when writing tests. It highlights more aspects like bloated tests which make it hard to figure out what they are about and proper usage of assertions to get better error messages. Especially if you don’t work with Test-Driven Development (TDD), it can be easy to come up with a test that looks good but stands in your way when it fails. The talk explores four scenarios that are outlined above, explain why it makes sense to think about them and actionable suggestions how to improve tests. Video producer: https://www.testjssummit.com
