2014-12-22[ct_cover] Fix paths of incl_dirs in cover specRafal Studnicki
It seems like the commit 5a3c4668908254ee930c8db2e5cf9741945f9b2b also broke the incl_dirs option and friends when given as relative paths. When a cover spec contains a relative path it is looked-up in the directory with the test results, not in the .cover file directory.
2014-09-18[ct] Fix path of cover export/import filesSiri Hansen
5a3c4668 accidentially changed the base directory for cover export and import files, if given as relative paths. This commit fixes this - the files are again expected to be given relative to the directory of the cover spec file itself, or else as absolute paths.
2014-06-05Improve cover analysis via common_testSiri Hansen
This addresses several bugs in common_test (ct) when using the cover analysis mechanism: In a ct test run, one can give a cover spec file which indicates that cover analysis shall be run, including a number of modules and a number of nodes. During the ct test run, multiple jobs may be started in test_server, and when the cover option is used, test_server would cover compile and analyse all given modules for each job. This commit instead allows the compilation and analysis to be explicitly ordered by ct for each test run. This way each module will only be cover compiled and analysed once. The cover log will be located in the common_test log directory (ct_run.<timestamp>), and the "Coverage log" link in each suite.log.html will point to this file. A new button is also added in the top level ct index file, which points to the cover log. This change also reduces the need of using the 'export' and 'import' options, since there is no longer any need to accumulate cover data over multiple test_server jobs. However, these options may still be used for importing and exporting cover data in order to store or accumulate data from multiple ct test runs. The 'nodes' option was earlier only used by ct to start cover on the given nodes before starting the first test_server job. After this job was completed, test_server would stop cover completely and then start it again for the next job without any knowledge of the 'nodes' options. For the next test_server jobs cover would therefore no longer be running on these nodes. Explcit calls to ct_cover:add_nodes had to be done in order to collect data through all test_server jobs. This bug has now been solved, since cover is no longer stopped between each test_server job. Finally, ct no longer stores cover data using ct_util:set_testdata. This was earlier used by ct_cover:add_nodes to make sure no node was added twice.This did, however, cause some problems when ct and cover were out of sync. ct could belive that a node was running cover and thus reject adding this node, while in reality cover had been stopped on the node (e.g. by test_server) so no cover data was collected. ct_cover:add_nodes will now instead use cover:which_nodes to check if a node is already running.

Also, rename some nodes to avoid node name clash between test cases, and ensure proper cleanup of nodes.
