public class CATest

extends Object

General purpose ClassAd tesing program. Designed to be run either interactively or in batch mode. Input consists of a sequence of "commands". Lines starting with '//' and empty lines are ignored. If input comes from a file, lines starting with whitespace are continuation lines, and are appended to the previous non-comment, non-empty line. If input comes from stdin (which only happens if there are no files mentioned on the command line), a continuation line is indicated by a backslash at the end of the previous line. The return status is the number of test failures (0 if all tests succeed). In the following, VAR denotes a sequence of letters, digits, and underscores starting with a letter. After processing of comments and continuation lines and before other processing, each occurrence of $VAR is replaced by the current value of variable VAR (the null string if VAR has never been assigned a value). Note that there is no way to "escape" or "quote" dollar signs in the input. Comands are as follows (case is significant).

echo args

Prints args.

set name = value

Sets an option. See below.

show name

Displays an option value.

let VAR = EXPR

Sets VAR equal to the expression EXPR.

eval VAR = EXPR

Sets VAR equal to the result of evaluating EXPR.

print EXPR

Displays EXPR.

same EXPR1 EXPR2

Compares EXPR1 and EXPR2 and prints a message if they differ.

diff EXPR1 EXPR2

Compares EXPR1 and EXPR2 and prints a message if they are the same.

quit

Immediately exit.

For the "same" and "diff" commands, comparison is "deep structural equality":

• Two constants match if they have the same value (for string constants, the comparison is case-sensitive).
• Two record expressions match if they have the same set of selectors and corresponding sub-expressions are (recursively) the same. Matching of selectors (attribute names) is not case-sensitive.
• Any other two non-atomic expressions match if they have the same operator and the same number of operands and corresponding operands match.

The command "set name = value" sets the named option to the indicated value. Leading and trailing space are stripped from the value. Otherwise, the name and value strings are processed verbatim. Options are either boolean or string valued. For boolean options, the value must be "true" or "false". Currently, the following options are supported. An attempt to set or show an unknown option is an error. Option names and values are case-sensitive.

Option	Type	Default	Comments
xmlinput	boolean	false	EXPR inputs are in XML
format	string	compact	format for printing EXPRs

Values for the the "format" options are

compact

Display each expression on one line in the "canonical native" representation.

xml

Display expressions in xml

pretty

Display expressions in the "native" format using newlies and indentation to improve readability.
