It offers a **unified API** to interact with web browsers, enabling **seamless testing** across different browser environments. With Playwright, you can write **robust** and **reliable tests** that cover a wide range of **scenarios**. By migrating from **jest-playwright** to **Playwright**, we are taking advantage of Playwright's extensive **features** and improved **performance**. Playwright offers enhanced support for modern web technologies, increased **stability**, and better **concurrency**. It also provides a broader range of **browser options**, including Chrome, Firefox, and WebKit, allowing you to test your application across **multiple browsers** easily. Take a look for playwright documentation -> https://playwright.dev/docs/intro For more information about our UI test doc -> https://docs.aspnetzero.com/en/aspnet-core-mvc/latest/Playwright-UI-Testing ### Power Tools **ASP.NET Zero Power Tools** further enhance the **development process** by enabling **faster** and **easier** project creation. You can utilize the developer interface, **command-line** interface, or **Visual Studio extension** to generate your project. In addition to **core features** like **user management** and **role-based authorization**, Power Tools support crud page generation, **multi-tenancy**, **audit logging**, **exception handling**, **background jobs**, **notifications**, **settings**, **localization**, **and more**. https://docs.aspnetzero.com/en/common/latest/Rapid-Application-Development I'm **thrilled** to share some **exciting news** related to **ASP.NET Zero Power Tools** with all of you. 🥳 #### 🧪 Unit Test Generation We are thrilled to announce a **new addition** to our Power Tools! We have introduced a powerful feature that allows you to **generate unit tests** for your **application services**. Unit testing plays a **crucial role** in ensuring the **quality** and **reliability** of your software. It helps identify **potential issues** early in the development process and provides a safety net for **future code changes**. However, writing unit tests manually can be **time-consuming** and tedious, especially as your project grows. With the latest update to our Power Tools, we have **simplified** and **automated** the **unit test generation** process. Now, you can **quickly** generate **unit tests** for your application services with just **a few clicks**. This feature intelligently **analyzes** your service **methods**, their input **parameters**, and expected **outputs**, and generates **test cases** accordingly. #### 🎨 UI Test Generation **Unit tests** are great for **testing** the **logic** of your application, but they **don't cover** the **user interface**. **UI tests** are a **great way** to ensure that your **application** is **working as expected**. However, **writing UI tests** can be **time-consuming** and **tedious**. In our **latest update**, we have introduced a highly **streamlined** and **automated** **UI test generation** process. With just a few clicks, you can now **quickly** generate **comprehensive** UI tests for your **application**. This new feature intelligently analyzes the UI elements of your application and **automatically** generates **corresponding** test **cases**. **Say goodbye** to the **tedious** **manual** test **creation** process and welcome **the speed** and **efficiency** of **automated UI testing**. Embrace this **powerful enhancement** and **revolutionize** your **testing workflow** with ASP.NET Zero Power Tools! You can run the generated UI tests **easily** with following command. ```bash npm test tests/mvc ``` UI Test Report ![Ui Test](https://aspnetzero.com/images/blog/ui-test-report.png) UI Test Report Detail ![Ui Test](https://aspnetzero.com/images/blog/ui-test-report-detail.png) ### 🌙 Better contract for readibility in Dark mode We have addressed an issue that many users have raised regarding **low contrast** and **readability** in **dark mode**, particularly when it comes to text. We **remain committed** to continuously **refining** and **optimizing** our **design** choices to provide you with a **seamless** and visually pleasing **experience** across **all modes**. Your **feedback** and **suggestions** are **invaluable** in **helping us** enhance the usability of Zero, and we **appreciate** your **contribution** to making our **product** even **better**. ### 🆔 Removed IdentityServer4 because it is deprecated We have an important update regarding the **authentication** and **authorization** **capabilities** of our ASP.NET Zero. After careful consideration, we have made the **decision** to **remove** **IdentityServer4** from our framework due to its **deprecation** and changes in **licensing policy**. IdentityServer4 has been a **widely used** and **trusted** open-source framework for implementing **authentication** and **authorization** in ASP.NET applications. However, **recent changes** in the **licensing policy** have made it a **non-viable** option for us to continue supporting within ASP.NET Zero. Moving forward, you will have the **flexibility** to **choose** the **authentication server** that best fits **your requirements**. **We are** actively **working** on **providing examples** and resources for integrating **OpenIdDict**, **Auth0**, and other **popular authentication providers**. These resources will **assist** you in **implementing** a secure and **reliable** **authentication solution** for your ASP.NET Zero applications. **Stay tuned** for **upcoming blog posts** and **documentation** that will **guide** you through the process of **integrating** alternative **authentication** providers into your ASP.NET Zero applications. We are **committed** to **assisting** you throughout this **transition** and providing you with the **necessary resources** to make the most of our product. - https://documentation.openiddict.com/guides/index.html - https://auth0.com/docs ### 📱Removed Xamarin template We have decided to **remove** the **Xamarin** template from our product. This **decision** was made after **careful consideration** of the current state of the **Xamarin platform** and its future prospects. **Don't worry** 😟, though! We are still **committed** to **providing** you with the best **mobile development** experience with **MAUI**. We will continue to support our **existing Xamarin** customers and provide them with the necessary resources **to migrate** to other platforms. ![Xamarin](https://aspnetzero.com/images/blog/maui-application.png) Check out for more -> https://docs.aspnetzero.com/en/aspnet-core-mvc/latest/Development-Guide-MAUI ### 🧷 Abp.HtmlSanitizer package To prevent **XSS attacks**, it's important to sanitize HTML input of actions. The **AbpHtmlSanitizerActionFilter** is a useful tool for this purpose. Configuring the **AbpHtmlSanitizer** easier with the new extension methods. ```csharp Configuration.Modules.AbpHtmlSanitizer() .KeepChildNodes() .AddSelector(); ``` ### 📦 Upgrade .NET packages to 7.0.5 We have **upgraded** the .NET packages to 7.0.5. Keeping libraries up-to-date is important to increase **performance** and get rid of **security** vulnerabilities. ### 🙏Conclusion We hope you enjoy these new **features** and **enhancements**.
