From ea5624c3d04c35f5a269b6f7431c135330c9b9b5 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Sat, 13 Mar 2010 14:11:22 +0100 Subject: * apt-pkg/deb/debversion.cc: - consider absent of debian revision equivalent to 0 (Closes: #573592) This moves the existing testcase for version comparison to "my" directory, adds a few more tests (e.g. the tests used in cupt) and rewrites the testcases runner: The runner does now call dpkg --compare-versions to check what dpkg thinks about the comparison - all done in less code ;) --- test/libapt/compareversion_test.cc | 123 ++++++++++++++++++++ test/libapt/makefile | 6 + test/makefile | 7 -- test/versions.lst | 64 +++++++++- test/versiontest.cc | 233 ------------------------------------- 5 files changed, 189 insertions(+), 244 deletions(-) create mode 100644 test/libapt/compareversion_test.cc delete mode 100644 test/versiontest.cc (limited to 'test') diff --git a/test/libapt/compareversion_test.cc b/test/libapt/compareversion_test.cc new file mode 100644 index 000000000..b6213e84c --- /dev/null +++ b/test/libapt/compareversion_test.cc @@ -0,0 +1,123 @@ +// -*- mode: cpp; mode: fold -*- +// Description /*{{{*/ +/* ###################################################################### + + Version Test - Simple program to run through a file and comare versions. + + Each version is compared and the result is checked against an expected + result in the file.
