### 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.

### Source excerpt

MongoDB database is one of the most popular NoSql solutions on the market today. Of course, it provides support for .NET Core, as well as for other popular programming languages and frameworks. In this article, I want to share my experience when I started to use Mongo as the main database with the .NET Core application. Before, I mainly used relational databases for a long time, and some NoSQL terms were confusing for me. Just like for many developers with a background in relational databases. You need to switch mindset - from relations and schema to no relations and schemaless.
