Abstract

The ALMA software is a large collection of modules, which implements the functionality needed for the observatory day-to-day operations, including among others Array/Antenna Control, Correlator, Telescope Calibration and Data Archiving. Many software patches must periodically be applied to fix problems detected during operations or to introduce enhancements after a release has been deployed and used under regular operational conditions. Under this scenery, it has been imperative to establish, besides a strict conguration control system, a weekly regression test to ensure that modications applied do not impact system stability and functionality. A test suite has been developed for this purpose, which reflects the operations performed by the commissioning and operations groups, and that aims to detect problems associated to the changes introduced at different versions of ALMA software releases. This paper presents the evolution of the regression test suite, which started at the ALMA Test Facility, and that has been adapted to be executed in the current operational conditions. Topics about the selection of the tests to be executed, the validation of the obtained data and the automation of the test suite are also presented.
