Accelerated Continuous Testing with Test Impact Analysis - Part 1

This post introduces Test Impact Analysis (TIA) as a feature within Azure Pipelines to accelerate continuous testing. It explains how TIA incrementally validates code commits by automatically selecting and running only relevant tests, thereby reducing test execution time and improving feedback loops. The post details the enabling of TIA via the Visual Studio Test task, including specific configurations for IIS interactions using a .runsettings file. It also outlines the components of robust test selection (existing impacted tests, previously failing tests, newly added tests) and the current scope of TIA support, including limitations like multi-box topology and .NET Core.
