AbslrQcl -Test Driven Development (TDD) is an agile software development technique and it is one of the core development practices of Extreme Programming WP). I n TDD, developers write automatically executable tests prior to writing the code they test. We ran a set of experiments to empirically assess different parameters ofthe TDD. We compared TDD to a more "traditionally" oriented iterative test-last development process (ITL). Our preliminary results show that TDD is not substantially different from ITL and our qualitative findings about a development processes are different from results obtained from other researchers.

A peak-search method for high resolution gamma-ray spectroscopy, based entirely on spectrum convolution, is presented. The detection of the peak and determination of the peak position, width and area can be realized in successive steps, independent of each other. To realize each of the steps, the spectrum is convoluted with an appropriate near-optimal function. Analytical expressions for the uncertainties of positions, areas and widths can be derived. For resolving doublets the standard least-square technique is used, but on the convoluted spectra, avoiding the problems associated with the background component. The performance of the software package based on the proposed method was successfully tested against two standard sets of test spectra of the International Atomic Energy Agency and intercomparison with other peak-search packages proves that the proposed approach is robust and reliable.
