Software testing is a difficult, time-consuming process that requires technical sophistication and proper planning. This is especially true for the large-scale software projects of High Energy Physics where constant modifications and enhancements are typical. The automated nightly testing is the important component of NICOS, NIghtly COntrol System, that manages the multi-platform nightly builds based on the recent versions of software packages. It facilitates collective work in collaborative environment and provides four benefits to developers: repeatability (tests can be executed more than once), accumulation (results are stored and reflected on NICOS web pages), feedback (automatic e-mail notifications about test failures), user friendly setup (configuration parameters can be encrypted in the body of test scripts). The modular structure of NICOS allows plugging in other validation and organization tools, such as QMTest and CppUNIT. NICOS classifies tests according to their granularity level and purpose. The low level structural tests reveal compilation problems, inconsistencies in package configuration, such as circular dependencies, and simple isolated bugs. The results for these three groups of tests are published for each package of the software project. The integrated (or behavioral) tests find bugs at levels of users scenarios and NICOS generates the special web page with their results. The NICOS tool is currently used to coordinate the efforts of more than 100 developers for the ATLAS project at CERN and included in the tool library of the LHC computing proje
