A test tool for testing application programs of the type that are deployed on a server computer for access by multiple users over a network is embodied in a computer program comprising a command module and a core module. The command module contains a number of different commands, each of which performs a different user function of the application program under test. Each of the commands comprises a series of programmed instructions that cause a computer running the test tool to perform a user function of the application program under test via a client connection to the application. Each command has an execution segment and a verification segment. Each command is also assigned a unique name. A test operator can then create test scripts containing any desired sequence of command module commands using the simple names assigned to each command. The command module is rewritten and/or customized for each different application program to be tested. The core module is independent of the command module and performs the core functionality of the test tool. The core module comprises instructions that enable the computer on which the test tool is running to execute concurrently, on each of a plurality of different client connections to the application program under test, a series of command module commands specified by name in a test script.

A microprocessor architecture that includes an arithmetic logic unit (ALU), a bit processing unit (BPU), a register file and an instruction register is disclosed. The BPU performs complex logical operations in a single clock cycle. The ALU continues to perform the slow arithmetic operations (e.g., multiply, divide). The BPU has two special purpose registers, a zero flag and a match flag, which are used for program execution control. The BPU performs bit manipulations on data stored in and received from the register file and/or individual fields in the instruction currently being executed by the BPU.
