A build pipeline refers to the automated process of building software by breaking it down into discrete steps. This document discusses how TeamCity, a build management and continuous integration tool, can be used to create build pipelines. It provides an example pipeline with steps for checking out sources, compiling code, running tests at different stages, generating reports, and publishing results. The benefits of a pipeline include running different test types in parallel and tracking dependencies between steps to speed up the overall build process.
