Various regression test selection strategies have been developed to establish the correctness of software systems upon deployment of COTS upgrades. These strategies recommend a smaller regression test suite to be reexecuted. We present a process that identifies the patch impact on the system and localizes the source of potential errors without executing the system test suite. The impact is analyzed based on verifying the behavior of affected COTS API execution-sequences. An API executionsequence is called affected when one or more of the altered functions of the COTS upgrade are part of COTS API execution-sequence that interfaces with application components. A wrapper-based passive test oracle has been developed to check the correctness of the behavior of these execution-sequences. The changed behavior of these execution-sequences reflects the patch impact. A case study has been conducted and the results are encouraging.

“…All such potential errors are reported and proposed to trace into the application source code for appropriate action. To identify the behavioral change, a wrapper-based passive test oracle [11] has been proposed. The test oracle tests the API execution-sequences, performs behavior checks and identifies the changes in the behaviors.…”

“…There are several plug-ins available for UML modeling in Eclipse. Omondo EclipseUML [9] is the most noticeable one, which is a graphical software modeling tool, using the Unified Modeling Language (UML) as its primary notation. We can use EclipseUML for diagram design, create JAVA classes automatically and switch between applications and UML classes diagram freely.…”

In order to adapt different languages and platforms, the paper discusses how to process and validate IDL symbol table and intermediate code by XML API. It puts emphasis on IDL API extension towards DOM API based on the idea of combining XML with IDL compilers. At last, the IDL compiler designing framework based on XML API is given, in which compiler front end can be managed and validated by some XML techniques and tools, IDL API can be validated on the basis of test, so IDL intermediate code is provided with maintainability, portability and generation. IDL compiler can be developed and extended by XML-based API, which realizes versatility and portability of modern compiler.The interface definition language (IDL) is a special-purpose language for describing the interfaces of a software component. From Distributed Computing Environment (DCE) to CORBA, DCOM and Java RMI use IDL to describe interface. Some IDL compilers have been developed over the past ten years, such as Flick [1] , IDL2WSDL [2] and MICO [3] . There are many compiling code production tools, such as JavaCC (a Java parser generator) and SableCC (an LALR (1) parser and AST builder generator) [4] . JavaCC provides a lot of modern grammars, such as Java, HTML and C/C++ [5] , which is the reason why it is widely used in compiler development. For example, it has developed the IDL compiler based on CORBA, which accepts an IDL interface specification and outputs an implementation of the specification. Typically, its implementation is a set of data type declarations, stubs of Client and skeletons of Server written in a conventional programming language, such as C, C++ or Java.On the other hand, XML is a kind of flexible exchange format that can represent many classes of data, including semi-structured records, structured documents and heterogeneous data. The increasing importance of XML as a data representation format leads to several proposals for facilitating the development of applications that operate on XML data. These proposals range from API-based interfaces to XML-based programming languages. However there are few reports about XML in IDL compiler development. GCCXML Kitware project [6] , where XML is adopted to output procedural information. It uses gcc_xml as preprocessor based on the GNU C++

“…The test oracles using the component's API are smaller than the other test oracles. Initial data indicates that testing using the component's API does surprisingly well with a relatively small number of test cases [17].…”

“…A test oracle using a component's API (application programmer interface) is one in which the component's interface is used to check the behaviour of the component [17]. Clearly the amount of checking that can be done with such an oracle depends on how observable the internal state of the component is through its public interface.…”
