Name

ipptoolfile - ipptool file format

Description

The ipptool(1) program accepts free-form plain text files that describe one or more IPP requests. Comments start with the "#" character and continue to the end of the line. Each request is enclosed by curly braces, for example:

    # This is a comment
    {
      # The name of the test
      NAME "Print PDF File"

      # The request to send
      OPERATION Print-Job

Top-Level Directives

The following directives can be used outside of a test:

{ test }
Defines a test.

DEFINE variable-name value
Defines the named variable to the given value. This is equivalent to specifying -d variable-name=value on the ipptool(8) command-line.

DEFINE-DEFAULT variable-name value
Defines the named variable to the given value if it does not already have a value.

FILE-ID "identifier"
Specifies an identifier string for the current file.

IGNORE-ERRORS yes

IGNORE-ERRORS no
Specifies whether, by default, ipptool(8) will ignore errors and continue with subsequent tests.

INCLUDE "filename"

INCLUDE <filename>
Includes another test file. The first form includes a file relative to the current test file, while the second form includes a file from the ipptool(8) include directory.

INCLUDE-IF-DEFINED name "filename"

INCLUDE-IF-DEFINED name <filename>
Includes another test file if the named variable is defined. The first form includes a file relative to the current test file, while the second form includes a file from the ipptool(8) include directory.

INCLUDE-IF-NOT-DEFINED name "filename"

INCLUDE-IF-NOT-DEFINED name <filename>
Includes another test file if the named variable is not defined. The first form includes a file relative to the current test file, while the second form includes a file from the ipptool(8) include directory.

SKIP-IF-DEFINED variable-name

SKIP-IF-NOT-DEFINED variable-name
Specifies that the remainder of the test file should be skipped when the variable is or is not defined.

STOP-AFTER-INCLUDE-ERROR no

STOP-AFTER-INCLUDE-ERROR yes
Specifies whether tests will be stopped after an error in an included file.

TRANSFER auto
Specifies that tests will, by default, use "Transfer-Encoding: chunked" for requests with attached files and "Content-Length:" for requests without attached files.

TRANSFER chunked
Specifies that tests will, by default, use the HTTP/1.1 "Transfer-Encoding: chunked" header. This is the default and is equivalent to specifying -c on the ipptool(8) command-line. Support for chunked requests is required for conformance with all versions of IPP.

TRANSFER length
Specifies that tests will, by default, use the HTTP/1.0 "Content-Length:" header. This is equivalent to specifying -l on the ipptool(8) command-line. Support for content length requests is required for conformance with all versions of IPP.

VERSION 1.0

VERSION 1.1

VERSION 2.0

VERSION 2.1

VERSION 2.2
Specifies the default IPP version number to use for the tests that follow.

Test Directives

The following directives are understood within a test:

ATTR out-of-band-tag attribute-name

ATTR tag attribute-name value(s)
Adds an attribute to the test request. Out-of-band tags (admin-define, delete-attribute, no-value, not-settable, unknown, unsupported) have no value. Values for other tags are delimited by the comma (",") character - escape commas using the "\" character. Common attributes and values are listed in the IANA IPP registry - see references below.

ATTR collection attribute-name { MEMBER tag member-name value(s) ... } [ ... ,{ ... } ]
Adds a collection attribute to the test request. Member attributes follow the same syntax as regular attributes and can themselves be nested collections. Multiple collection values can be supplied as needed, separated by commas.

COMPRESSION deflate

COMPRESSION gzip

COMPRESSION none
Uses the specified compression on the document data following the attributes in a Print-Job or Send-Document request.

DELAY seconds[,repeat-seconds]
Specifies a delay in seconds before this test will be run. If two values are specified, the second value is used as the delay between repeated tests.

DISPLAY attribute-name
Specifies that value of the named attribute should be output as part of the test report.

EXPECT attribute-name [ predicate(s) ]

EXPECT ?attribute-name predicate(s)

EXPECT !attribute-name
Specifies that the response must/may/must not include the named attribute. Additional requirements can be added as predicates - see the "EXPECT PREDICATES" section for more information on predicates. Attribute names can specify member attributes by separating the attribute and member names with the forward slash, for example "media-col/media-size/x-dimension".

EXPECT-ALL attribute-name [ predicate(s) ]

EXPECT-ALL ?attribute-name predicate(s)
Specifies that the response must/may include the named attribute and that all occurrences of that attribute must match the given predicates.

FILE filename
Specifies a file to include at the end of the request. This is typically used when sending a test print file.

IGNORE-ERRORS no
Specifies whether ipptool(8) will ignore errors and continue with subsequent tests.

MONITOR-PRINTER-STATE [ printer-uri ] { EXPECT attribute-name [ predicate(s) ] }
Specifies printer state monitoring tests to run in parallel with the test operation. The monitoring tests will run until all of the EXPECT conditions are satisfied or the primary test operation has completed, whichever occurs first.

PAUSE "message"
Displays the provided message and waits for the user to press a key to continue.

REQUEST-ID number

REQUEST-ID random
Specifies the request-id value to use in the request, either an integer or the word "random" to use a randomly generated value (the default).

RESOURCE path

SKIP-IF-DEFINED variable-name

SKIP-IF-NOT-DEFINED variable-name
Specifies that the current test should be skipped when the variable is or is not defined.

SKIP-PREVIOUS-ERROR yes

SKIP-PREVIOUS-ERROR no
Specifies whether ipptool(8) will skip the current test if the previous test resulted in an error/failure.

STATUS status-code [ predicate ]
Specifies an expected response status-code value. Additional requirements can be added as predicates - see the "STATUS PREDICATES" section for more information on predicates.

Expect Predicates

The following predicates are understood following the EXPECT test directive:

COUNT number
Requires the EXPECT attribute to have the specified number of values.

DEFINE-MATCH variable-name
Defines the variable to "1" when the EXPECT condition matches. A side-effect of this predicate is that this EXPECT will never fail a test.

DEFINE-NO-MATCH variable-name
Defines the variable to "1" when the EXPECT condition does not match. A side-effect of this predicate is that this EXPECT will never fail a test.

DEFINE-VALUE variable-name
Defines the variable to the value of the attribute when the EXPECT condition matches. A side-effect of this predicate is that this EXPECT will never fail a test.

DISPLAY-MATCH "message"
Displays the specified message when the EXPECT condition matches.

IF-DEFINED variable-name
Makes the EXPECT conditions apply only if the specified variable is defined.

IF-NOT-DEFINED variable-name
Makes the EXPECT conditions apply only if the specified variable is not defined.

IN-GROUP tag
Requires the EXPECT attribute to be in the specified group tag.

OF-TYPE tag[(limits)|tag|...]
Requires the EXPECT attribute to use one of the specified value tag(s). Most value tags also support the specification of limits in parenthesis, for example "name(42)" would allow nameWith/WithoutLanguage strings up to 42 octets in length, "name(4:MAX)" would allow nameWith/WithoutLanguage strings between 4 and 255 octets in length, and "integer(-273:MAX)" would allow integers between -273 and 2147483647.

REPEAT-LIMIT number

Specifies the maximum number of times to repeat if the REPEAT-MATCH or REPEAT-NO-MATCH predicate is specified. The default value is 1000.

REPEAT-MATCH

REPEAT-NO-MATCH
Specifies that the current test should be repeated when the EXPECT condition matches or does not match.

SAME-COUNT-AS attribute-name
Requires the EXPECT attribute to have the same number of values as the specified parallel attribute.

SAVE-CONTENT filespec

SAVE-ALL-CONTENT filespec
Saves all "http" or "https" URI values to the specified location. The filespec value is a filename or directory path and can contain the special strings "%basename%" to insert the base filename from the URI, "%ext%" to insert the extension from the URI, and "%index%" to insert the value number starting at 1.

WITH-ALL-CONTENT available

WITH-CONTENT available
Requires that all URI values be accessible. A "http" or "https" URI must respond to a GET request while a "ipp" or "ipps" URI must respond to a HEAD request.

WITH-ALL-CONTENT valid

WITH-CONTENT valid
Requires that all "http" and "https" URI values be accessible and provide valid content.

WITH-ALL-CONTENT valid-icon

WITH-CONTENT valid-icon
Requires that all "http" and "https" URI values be accessible and provide valid PNG images for icons - 48x48, 128x128, or 512x512 in size with transparency.

WITH-ALL-MIME-TYPES mime/type[,...,mime/type]

WITH-MIME-TYPES mime/type[,...,mime/type]
Requires that all URI values provide one of the listed MIME media types. For non-content tests, the target Printer must respond to HTTP HEAD requests with the MIME media type that would be returned by a GET or POST requests. For "http" and "https" content tests, ipptool sends a HTTP GET request. For "ipp" and "ipps" content tests, ipptool sends an IPP Get-Printer-Attributes request.

WITH-ALL-RESOURCES "literal string"

WITH-ALL-RESOURCES "/regular expression/"
Requires that all URI values contain a matching resource (including leading /).

WITH-ALL-SCHEMES "literal string"

WITH-ALL-SCHEMES "/regular expression/"

WITH-ALL-VALUES "false"

WITH-ALL-VALUES "true"
Requires that all values of the EXPECT attribute match the boolean value given.

WITH-ALL-VALUES "/regular expression/"
Requires that all values of the EXPECT attribute match the regular expression, which must conform to the POSIX regular expression syntax. Comparisons are case-sensitive.

WITH-ALL-VALUES-FROM attribute-name
Requires that all value(s) of the EXPECT attribute matches the value(s) in the specified attribute. For example, "EXPECT-ALL media-col-database/media-source WITH-ALL-VALUES-FROM media-source-supported" requires that all the "media-source" values are listed as a value of the "media-source-supported" attribute.

Status Predicates

The following predicates are understood following the STATUS test directive:

DEFINE-MATCH variable-name
Defines the variable to "1" when the STATUS matches. A side-effect of this predicate is that this STATUS will never fail a test.

DEFINE-NO-MATCH variable-name
Defines the variable to "1" when the STATUS does not match. A side-effect of this predicate is that this STATUS will never fail a test.

IF-DEFINED variable-name
Makes the STATUS apply only if the specified variable is defined.

IF-NOT-DEFINED variable-name

Generate-File Parameters

The GENERATE-FILE directive dynamically generates raster pages for the destination printer. Each page consists of a black border and the text "TEST-PAGE ####" repeated in the interior in several shades of gray and colors. The following parameters are supported:

COLORSPACE auto

COLORSPACE bi-level

COLORSPACE color

COLORSPACE monochrome

COLORSPACE colorspace_bits
Specifies the output color space and bit depth. "auto" chooses an available combination with preference for full color, "bi-level" chooses a B&W (bitmap) color space, "color" chooses a full color combination, and "monochrome" chooses a grayscale combination. Otherwise, the value must be one of the registered IPP "pwg-raster-document-type-supported" keywords. NOTE: The "device N" color spaces are not current supported.

FORMAT image/pwg-raster

FORMAT image/urf
Specifies the raster format to use, either "image/pwg-raster" (PWG Raster) or "image/urf" (Apple Raster). The default is "image/urf" if supported, "image/pwg-raster" otherwise.

MEDIA default

MEDIA ready

MEDIA media-size-name
Specifies the output media size. "default" uses the printer's default media size while "ready" uses the first ready (loaded) media reported by the printer. Other media size names must conform the PWG self-describing media size format.

NUM-COPIES copies
Specifies the number of copies to produce. The default is 1 copy.

NUM-PAGES pages
Specifies the number of pages to produce. The default is 1 page for single-sided output and 2 pages for double-sided output.

ORIENTATION landscape

ORIENTATION portrait

ORIENTATION reverse-landscape

ORIENTATION reverse-portrait
Specifies the orientation of the output. The default is "portrait".

RESOLUTION default

RESOLUTION max

RESOLUTION min

RESOLUTION resolutiondpcm
