+# Publication validator
+
+This is a supplementary subproject of kotlinx.coroutines to test its publication correctness.
+
+It is used as part of "Dependency validation" build chain on TeamCity:
+* kotlinx.corotoutines are built with `publishToMavenLocal`
+* kotlinx.coroutines are built with `npmPublish -PdryRun=true` to have a packed publication
+* `NpmPublicationValidator` tests that version of NPM artifact is correct and that it has neither source nor package dependencies on atomicfu
+* `MavenPublicationValidator` depends on the published artifacts and tests artifacts binary content and absence of atomicfu in the classpath
