Theoretical predictions in high energy physics are often provided in the form of Monte Carlo generators. Comparisons of predictions from different programs and/or different initialization set-ups are often necessary. MC-TESTER can be used for such tests of decays of intermediate states (particles or resonances) in semi-automated way. Our test consists of two steps. Different Monte Carlo programs are run: events with decays of a chosen particle are searched, decay trees are analyzed and appropriate information is stored. Then, at the analysis step, a list of all found decay modes is defined and branching ratios are calculated for both runs. For each plot a measure of the difference of the distributions is calculated and its maximal value over all histograms for each decay channel is printed in a summary table. As an example of MC-TESTER application, we include a test with the tau lepton decay Monte Carlo generators, TAUOLA and PYTHIA. The HEPEVT (or LUJETS) common block is used as a source of information on the generated events. This new version of MC-TESTER now also allows testing of Monte Calo generators with event records in C++ HepMC format. An example is provided with tau decays analyzed from PYTHIA 8.1.
