5.Change the following two arguments in the executeArgs value of the test description file in use.

Change the argument to the -FileNameoption in the test description to correspond to the signature file name. It will look something like this:

-FileName ./name.sig

Change the argument to the -packageoption in the test description to the top-level package you are testing:

-packagepackage_name

When these items are in place, the JavaTest harness handles execution of the signature test as part of the test suite. It does so by executing the following class by specifying it in the test description file as the value of the executeClass parameter with arguments specified by the executeArgs parameter: com.sun.tdk.signaturetest.Test.

Report Formats

You can cause SignatureTest command report messages to be sorted (default), or unsorted by specifying the -FormatPlainflag at the command line. See

CODE EXAMPLE A-4under “Example SignatureTest Command” on page 32 to see a sorted report that was generated into a plain text file with the -outoption. Report messages contain the following types of information:

The versions of both the reference API and the API under test

The total number of errors found

The differences such as added or missing classes, superclasses, fields, or methods

The fully qualified name of the enclosing class related to any missing or added description

Two errors for any modified item, one for a missing item and another for an added item

A description of any incompatibility in the API implementation under test

Sorted Report

Report messages are sorted by default. Unlike the unsorted format, duplicate messages are removed. To accurately compare the error totals between formats, the sorted report prints two error counts: the total number of errors and the total number of duplicates.

The sorted report groups error messages by category of difference with classes within each category ordered alphabetically by name, and empty categories are ignored. This is the category ordering sequence:

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.
