Using the Signature Test Tool

This chapter provides a synopsis of each of the SigTest tool commands along with their available options and arguments. It contains these sections:

■Signature Test Tool Basics

■Setup Command

■SignatureTest Command

■SetupAndTest Command

■Merge Command

■Report Formats

Also see Appendix A for examples of each SigTest tool command that you can run.

Signature Test Tool Basics

The SigTest tool operates from the command line to generate or manipulate signature files. A signature file is a text representation of the set of public and protected features provided by an API. Test suite developers include it in a finished test suite as a signature reference for comparison to the technology implementation under test. The following list shows the commands that are available.

■Setup - Creates a signature file from either an API defined by a specification or a reference API implementation.

■SignatureTest - Compares the reference API represented in the signature file to the API under test and produces a report. This is the test that becomes part of a finished test suite.

■SetupAndTest - Executes the Setup and SignatureTest commands in one operation.

Sun Microsystems, founded in 1982, was a significant player in the computing industry, best known for its innovative technology solutions and workstations, particularly the Sun-4, which represented a key milestone in the company's history. The Sun-4 architecture, launched in 1987, utilized the SPARC (Scalable Processor Architecture) RISC processor, notable for its high performance and scalability.

One of the primary features of Sun Microsystems' platforms was their ability to efficiently handle multitasking and resource management, making them ideal for enterprise-level applications and development environments. Sun-4 workstations boasted impressive graphics capabilities with the addition of advanced graphical user interfaces, support for color displays, and the SUNVIEW windowing system, which enhanced user experience and productivity.

The Sun-4 systems also supported the SunOS operating system, which was based on UNIX. This operating system was engineered for stability and robustness, offering features like multiuser support, networked environments, and advanced security options. Moreover, SunOS provided seamless integration with various programming languages, including C and C++, facilitating software development that aligned with industry standards.

Another standout characteristic of Sun Microsystems was its commitment to open systems and standards. By providing developers with comprehensive tools and environments, such as the Standardized Application Programming Interface (API) and support for networking protocols, Sun facilitated interoperability among different computing platforms. The emphasis on open architecture also meant that customers could easily upgrade their systems without being locked into proprietary solutions.

Sun Microsystems was also ahead of its time with innovations in network computing. Their workstations were among the first to support network file systems and distributed computing concepts, enabling seamless data sharing across multiple systems. With the introduction of the Network File System (NFS), Sun revolutionized how data was accessed and managed across networks, which played a significant role in the evolving landscape of client-server computing.

In summary, the Sun Microsystems 2 and its successive innovations in workstation technology highlighted the company's forward-thinking approach. By integrating powerful performance with open systems, robust operating systems, and advanced networking capabilities, Sun laid the groundwork for modern computing, influencing various sectors from academia to enterprise solutions. Even after its acquisition by Oracle in 2010, the legacy of Sun Microsystems continues to be felt across the computing industry.
