sbotest (sbotools-based reverse dependency build tester) sbotest uses the sbotools library and sbo-maintainer-tools to build and test SlackBuilds and their reverse dependencies (zero, one or all levels). Dry run and package archive features are included, as well as a special option to build-test the entire repository. Tests for missing shared object dependencies and perl, python and ruby incompatibility are available upon build failure. sbotest is intended to run in a clean-build environment, such as a virtual machine or Docker image. Because it calls useradd, groupadd and removepkg non-interactively, using sbotest on a general-purpose Slackware installation is not recommended.
