### AI overview

This article argues that end-to-end test-data setup is often the main design challenge, because tests must create consistent domain records while running alongside other tests. It recommends using browser-testing tools in the backend's language when possible, keeping meaningful relationships inline, and extracting small creation helpers without hiding scenario intent.

### Source excerpt

The browser is often the easiest part of an end-to-end test. Consider a test that verifies a user can complete an overdue task. The visible interaction is small: sign in, find the task, click Complete, and observe the new status. Before any of that can happen, the test needs a workspace, a user, a project, and [...] The post Write End-to-End Tests in Your Backend's Language appeared first on Atomic Spin.

### AI overview

DigitalOcean App Platform now supports native .NET buildpacks, allowing developers to deploy .NET applications from Git repositories without maintaining Dockerfiles. The platform detects the project, selects the SDK version, restores dependencies, and builds the application for production.

### Source excerpt

The .NET ecosystem continues to power a significant share of enterprise and cloud-native applications, from web APIs and microservices to full-stack applications built with ASP.NET Core. Developers building with C#, F#, and Visual Basic need a deployment experience that matches the productivity of the framework itself: push code, and let the platform handle the rest. Today, we're excited to announce native .NET buildpack support on DigitalOcean App Platform. You can now deploy your .NET applications directly from a Git repository without writing or maintaining Dockerfiles. App Platform automatically detects your .NET project, installs the correct SDK version, and builds your application for production. Benefits Zero Configuration: Push your .NET code to a Git repository, and App Platform handles runtime detection, SDK installation, and build configuration automatically--no Dockerfile required. Multi-Language Support: Build applications in C#, Visual Basic, or F# using the .NET and ASP.NET Core frameworks, all with the same streamlined deployment experience. Automatic SDK Management: App Platform selects the appropriate .NET SDK version based on your project's TargetFramework or global.json configuration, supporting .NET 8.0, 9.0, and 10.0. Production-Ready Defaults: The buildpack compiles with the Release configuration by default and automatically detects ASP.NET Core web applications to configure the correct process type. How Detection Works Once you connect your Git repository, App Platform identifies your application as a .NET project by looking for specific files in your repository root. App Platform confirms a .NET application if it detects any of the following: Solution files: *.sln, *.slnx Project files: *.csproj, *.vbproj, *.fsproj File-based apps: *.cs Once detected, the buildpack takes over: SDK Detection: Determines the required .NET SDK version from your TargetFramework property or global.json file Dependency Restore: Runs dotnet restore to fetch NuGet pa

### AI overview

This article presents the TeamCity C# scripting API for automating application builds. It describes integration with the .NET CLI, including process execution and detailed build, warning, error, and test information, as well as running processes in Docker containers and using ASP.NET Core-style composition and dependency injection. It also introduces packages for running, debugging, testing, and templating C# build scripts.

### Source excerpt

Начиная с первых версий .NET Core для сборки приложений, компания Microsoft предоставляет простой и удобный интерфейс командной строки (.NET CLI). Его возможности покрывают большинство потребностей по сборке, упаковке и тестированию приложений. Несмотря на это, по мере роста приложения, увеличения количества его составных частей/сборок/пакетов, усложнения процессов тестирования и развертывания, рядом с проектом часто появляются такие файлы сценариев как build.ps1, build.sh, build.cmd или даже полноценные инфраструктуры автоматизации построения приложений. В статье TeamCity C# script runner была предложена еще одна альтернатива - сценарии C#, которые особенно полезны, когда необходимо эффективно автоматизировать какой либо аспект сборки силами .NET разработчиков или DevOps, знакомыми с синтаксисом C#. Тогда же была упомянута идея расширить встроенный API сценариев для более глубокой интеграции с TeamCity и для поддержки наиболее частых вариантов использования. Предполагая, что API сценариев чаще всего будет задействован при сборке приложений, мы в первую очередь решили расширить именно его. В этой статье будут приведены примеры использования этого API.
