....Emerald system can thus be used to determine the quality of a software product after the development phase, or pre test phase. However it does not offer the capability of obtaining predictions based on the failure data collected during the testing phase. On the other hand, tools [31] like SMERFS [7], AT T SRE Toolkit, SoRel [23] CASRE [30,29,34] RAT [27] M elop ee [45] can be used to estimate software reliability using the failure data to drive one or more of the software reliability growth models (SRGM) These tools differ in the number of SRGMs they implement and the interfaces they ....

....collection and the model estimation be automated and tool based. Examples of reliability oriented data sets and tools can be found on the CD ROM that comes with the Handbook of Software Reliability Engineering [Lyu96] Examples of tools that can aid in software reliability estimation are SMERFS [Far88, Lyu96] and RelTools [Mus90] on Unix , CASRE on DOS and Windows [Lyu92, Lyu96] and SoRel on Macintosh computers [Kan93a. Lyu96] Example of a tool that can help in test case development, and that we discuss further later in this tutorial, is PairTest [Lei98] Figure 1 illustrates maximum ....

....The tool CASRE [11] was used to run the models. CASRE is a software reliability modeling tool implemented in a Microsoft Windows environment. The core modeling capabilities of this tool are the libraries originally implemented for version 5 of the software reliability modeling tool SMERFS [6]. The object code for these libraries was linked into the executable CASRE module. The command interface is a set of pull down menus that make it easy to navigate through the functional areas of the tool. Input data and model results are displayed both as text and as high resolution graphics that ....

....of real life data and applied statistical metrics to rank existing models [8] Such work is restricted by limitations on real life data and pre selection of models to be evaluated. Other existing tools are designed for users to select a model with best fit for their own sequence of failure data [4, 9]. These tools serve as a model selector for a particular set of input data. In comparison, TERSE evaluates a model using different sets of input data, various program structures, and a number of testing techniques. A user is allowed to update the TERSE library dynamically, with a new model that is ....

....CASRE [4] was used to run the same five models on the sequences. CASRE is a software reliability modeling tool implemented in a Microsoft Windows environment. The core modeling capabilities of this tool are the libraries implemented for version 5 of the software reliability modeling tool SMERFS [2]. Model validation is carried out using both maximum likelihood (ML) as well as least squares (LS) methods of parameter estimation. A recent study by Wood [7] shows that although LS estimates do not possess desirable properties of unbiasedness and minimum variance possessed by the ML estimates, ....

....inference for a successive sampling model that incorporates distinct fault types. Some personal computer based software for analyzing software reliability data is available commercially. For example, the package SMERFS 5 (Statistical Modeling and Estimation of Reliability Functions for Software) [20] requiring a FORTRAN 77 compiler computes the maximum likelihood estimates of the unknown parameters and their functionals (for example, reliability, intensity function, and time between failures) and the Kolmogorov goodness of fit statistics for many models that include the JM, Littlewood and ....
