Playwright for WordPress: A Practical Guide to Automating End-to-End Tests

Software Testing Magazine — Tue, 06 Oct 2026 16:27:02 +0000

Stop shipping browser bugs when you update your WordPress website. This article explains how to set up Playwright automated tests for WordPress, from saved logins to continuous integration, before the next update. Author: Samrat Biswas, Unified Infotech Private Limited Imagine, your team ships a new landing page, tests it in Chrome, and finally launches it. Everything is fine until you receive a support email. A customer on Safari is unable to submit a signup form. One of your team members opens Firefox to check and notices the dropdown menu doesn’t even open. Nobody saw that coming, as every test, every single time, ran in one browser. The site worked, but it just did not work on every browser. This is one of the most common problems in WordPress QA, and Playwright for WordPress can solve this problem. Chromium, Firefox, and WebKit render pages and run scripts differently, so a test suite built around one browser will catch some bugs, but not browser-specific compatibility issues. Playwright runs the same test across all three browsers from one codebase using configuration. It automates the clicks, form fills, and page checks, eliminating the need for a human tester. Why Use Playwright for WordPress E2E Testing? A WordPress site often combines themes, custom JavaScript, APIs, plugins, page builders, forms, and third-party services. Testing everything with traditional E2E testing becomes complicated. Traditional testing frameworks that may depend on separate browser drivers can easily break after major browser updates. Asynchronous REST API calls and page builder scripts [...]

Open Source Test Data Generators

Software Testing Magazine — Mon, 15 Jun 2026 12:00:22 +0000

In most of your software testing activities, you need data. Sometimes you can rely on a small sample, but if you want to perform some load testing or if you want to test a feature that needs to produce a multipage invoice, then you start to need more than just two or three occurrences. Test data generators are tools that can help you in this task with the automatic generation of hundreds or thousands of customers, products or accounts items with different attributes for their id, email, name, etc. Test data generators can work in different mode: from the random approach to a more focused or intelligent way. Their goal is to use a predefined data structure to produce the data need for test in a specific format that could range from a spreadsheet file to SQL insert instructions. This article presents some open source test data generators. Do not hesitate to contact us to include any tool that that is not yet listed in this article.

Open Source API Testing Tools

Software Testing Magazine — Tue, 03 Mar 2026 20:00:19 +0000

The rising trend of using SOA and then microservices as a software architecture has led to the creation of multiple tools for automated testing of the services API. This article presents a list of open source API testing tools. Wikipedia defines an application programming interface (API) is a way for two or more computer programs to communicate with each other. This is the case currently for modern web and cloud software architectures, where clients communicate with server-side services, for instance to retrieve or update data. The API defines the communication protocol between the client and the services and how services will behave. You can use different protocols or architecture conventions to manage interactions in your applications. The Simple Object Access Protocol (SOAP) proposes to use XML as the message format and communicate requests through HTTP or SMTP. The Representational State Transfer (REST) differs from SOAP because SOAP is a protocol, whereas REST is an architectural style. Finally, you can use GraphQL that is a query language and server-side runtime as an alternative to REST. API testing tool selection technical criteria Besides the obvious license and price, if you pick a commercial API testing tool, there are many technical criteria that you can use to choose your API testing tool. Here are some of them: * How do you define and manage your tests (code, low code, no code) * Supported technologies (programming languages, platforms, …) * Integration with other components of the software development and delivery process like the CI/CD tools * Authentication and authorization * Logging and monitoring * Updates March 3 2026: added Hoppscotch, [...]

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 [...]
