To test the functionality of a computer system, automated testing may use an automation testing tool that emulates user interactions. A database may store words each having a colloquial meaning that is understood by a general population. For each of these words, the database may store associated computer instructions that can be executed to cause a computer to perform the function that is related to the meaning of the word. During testing, a word may be received having a colloquial meaning that is understood by a general population. The database may be queried for the received word and the set of computer instructions may be returned by the database. The automated testing tool may then perform the function returned to the colloquial meaning of the word. The words stored in the database may be in English or another language.

A software system is disclosed which facilitates the process of tracing the execution paths of a program, called the client. The tracing is performed without requiring modifications to the executable or source code files of the client. Trace data collected during the tracing operation is collected according to instructions in a trace options file. At run time, the tracing library attaches to the memory image of the client. The tracing library is configured to monitor execution of the client and to collect trace data, based on selections in the trace options file. Conditional tracing, through the use of triggers and actions taken in response to the triggers, allows the developer to control the tracing operation. The triggers can be conditional triggers in which the corresponding action is taken only if a conditional expression is satisfied. The system can trace multiple threads and multiple processes. The tracing system provides a remote mode and an online mode. In remote mode, the developer sends the trace control information (which can include triggers and corresponding actions) to a remote user site together with a small executable image called the agent that enables a remote customer, to generate a trace file that represents execution of the client application at the remote site. In online mode, the developer can generate trace options (including triggers and corresponding actions), run and trace the client, and display the trace results in near real-time on the display screen during execution of the client program.

A system for automatically testing an application system graphical user interface (GUI) includes first and second application servers communicatively connected across a communication network. The second application server retrieves a GUI page provided by the first application server as part of the application system, and identifies text elements and user input objects in an image of the retrieved GUI page. Each user input object is then associated with a text element. Test parameter values are retrieved from a database storing test parameter data, and the application system is tested. In particular, for each user input object of the GUI page, a respective test parameter value is provided that is associated in the database with a same text element as is associated with the user input object.

The invention relates to a process and apparatus for tracing software entities, more particularly a tracing tool providing tracing capabilities to entities in an application. The object-tracing tool provides software components to allow tracing the execution of an application. Tracing software entities is important for software developers to permit the quick localization of errors and hence facilitate the debugging process. It is also useful for the software user who wishes to view the control flow and perhaps add some modifications to the software. Traditionally, software-tracing tools have been confined to single node systems where all the components of an application run on a single machine. The novel tracing tool presented in this application provides a method and an apparatus for tracing software entities in a distributed computing environment. This is done by using a network management entity to keep track of the location of the entities in the system and by using a library of modules that can be inherited to provide tracing capabilities. It also uses a log file to allow the program developer or user to examine the flow, the occurrence of events during a trace and the values of designated attributes. The invention also provides a computer readable storage medium containing a program element to direct a processor of a computer to implement the software tracing process.
