Lintian::Tutorial::WritingTests — Short tutorial on writing tests SynopsisWarning: This document may be out of date. This document attempts to be a short / quick tutorial to the Lintian test suite from a test-writer’s perspective. As such, it will only cover the standard type of tests (from the “tests” suite). The guide will involve writing a…

Lintian::Tutorial::WritingChecks — Writing checks for Lintian SynopsisWarning: This tutorial may be outdated. This guide will quickly guide you through the basics of writing a Lintian check. Most of the work is in writing the two files: checks/<my-check>.pm checks/<my-check>.descAnd then either adding a Lintian profile or extending an existing one. DescriptionThe basics of writing a check…

Lintian::Tutorial::TestSuite — Quick intro to running the Lintian testsuite SynopsisWarning: This document may be out of date. This guide will quickly introduce you to running the Lintian test suite and some tricks. The Lintian test suite is fairly large and accordingly it can take a substantial amount of time to run. To speed up development,…
