Test Run:

Anglo-DT

Date:	2007-12-03
Test Suite Version:
Syntax:	XQuery

BaseX

Date:	2007-11-16
Test Suite Version:	1.0.2
Syntax:	XQuery
Transformation: Queries were run as supplied (after initializing the external variables).
Comparison: Based on the XQTS recommendations. Additionally, whitespaces were removed in results that are spanning several lines.
Other Comments: The test run took 56 seconds (Pentium M 1.6 GHz, 1.25 GB RAM), including serialization of the results to single files. Procedure: all XML documents are stored once in the database and re-opened if requested another time.

Berkeley DB XML

Date:	2006-12-13
Test Suite Version:
Syntax:	XQuery
Comparison: XML and fragment comparisons are performed by serializing the results, re-parsing them, and using a custom deep-equal like function. This function currently ignores any text nodes that consist entirely of whitespace.

DataDirect XQuery

Date:	2007-05-02
Test Suite Version:	1.0.2
Syntax:	XQuery
Transformation: 1. Standard Customizations - 1.1. Default Context Item: The initial context item is set by a 'fn:doc()' call - 1.2. Library Imports: Library hints are added for each 'import module' call 2. DataDirect XQuery Customizations - 2.1. XPST0005 detection: DataDirect XQuery runs without XPST0005 detection for most queries. When error code XPST0005 is expected an extra option was declared: declare option ddtek:detect-XPST0005 'yes'. - 2.2. When 'fn' is redeclared in the query, the 'fn:doc()' call to set the initial context will fail. To solve this 'xvsfn' is set to the default function namespace "http://www.w3.org/2005/xpath-functions" and the initial context declaration is changed to declare variable $input-context :=xvsfn:doc(...);
Comparison: The expected results are not changed in any way. The comparison algorithm for positive tests is based on the XQTS Catalog We use XMLUnit 1.0 for XML and Fragment comparisons and only accept 'identical' comparison results, both 'similar' and 'different' results are reported as failure For negative tests, differences in error codes are reported as success and the difference is listed as a comment
Other Comments: DataDirect XQuery 3.0 implements the January 2007 W3C Recommendation

eXist-db

Date:	2007-12-12T09:57:18.151+01:00
Test Suite Version:	1.0.2
Syntax:	XQuery
Transformation: The following tests have been evaluated against results provided by other XQuery processors. 1 Test name Reference software Considered result CastAs672 Saxon8.9J true
Comparison: The following tests have required a comparison method different from the standard one. 1 Test name Comparison method copynamespace-2 XML ForExprType057 UnnormalizedText ForExprType059 TextAsXML ForExprType060 TextAsXML Constr-inscope-1 TextAsXML Constr-inscope-3 TextAsXML Constr-inscope-4 TextAsXML UnnormalizedText : result text nodes are concatenated without introducing (normalized) spaces between them. TextAsXML : result string is evaluated as if it were XML, then an XML comparison is done.
Other Comments: The test run took 2026.836 seconds.

Galax

Date:	2007-10-17-05:00
Test Suite Version:
Syntax:	XQuery

Qexo

Date:	2006-12-05
Test Suite Version:	1.0.2
Syntax:	XQuery

Qizx

Date:	Tue Jan 15 16:22:49 GMT+01:00 2008
Test Suite Version:	1.0.2
Syntax:	XQuery
Transformation: Queries were run as supplied, except a few which were obviously buggy and therefore fixed. Some results have been changed when the comparison mode is 'Inspect' to make the test execution reproducible (for example current-date(), current-time() etc.) The last digit of some numeric results has been modified to accomodate precision issues.
Comparison: Comparisons as recommended by the guidelines. Whitespace is stripped before comparison in most cases, except when 'preserve' is present in the query.
Other Comments:

Saxon-SA

Date:	2006-11-17
Test Suite Version:	CVS
Syntax:	XQuery
Transformation: Queries were run as supplied, with no changes made to accommodate the test driver. A number of bug reports were raised against the test suite; in the following cases corrected results were used rather than the published results: bugs 3790, 3356, 3975. This run differs from previous submissions in that a new test driver written in Java is used, with a slightly different methodology for comparing results.
Comparison: XML comparisons are performed by canonicalizing the results using a modified version of James Clark's canonical XML processor The main modification is an option to strip whitespace text nodes; this is used only when necessary, and its use is always noted in a comment in the test results. Fragment and text comparisons are performed using three separate algorithms, reporting success if any one of them succeeds. First, a simple normalization that removes byte order marks and normalizes line endings, then compares the results byte by byte. Second, referencing the result as an external entity from a wrapped XML document, and performing canonicalization on the resulting document. Thirdly, assembling the fragment in a wrapper element by string concatenation and parsing the result. (This third technique is needed because the second fails on some results due to a bug in the JDK 1.5 XML parser, which has been reported to Sun.) If the expected result is an error, and the test produces an error, then it is reported as having been run successfully even if the error codes differ. In all cases where the error codes differ from those expected, this is recorded as a comment in the test report.
Other Comments: Tests of the trivial XQuery embedding have not been run because they would require extra work in the test driver and would prove nothing..

Sedna XML Database System

Date:	04/11/2007 16:49
Test Suite Version:	1.0.2
Syntax:	XQuery
Transformation: External variables are changed with fn:doc() calls.
Comparison: Text results are compared without changes. XML and XML Fragment results are compared using SXML comparator implemented in Scheme.

Stylus Studio

Date:	2006-09-20
Test Suite Version:	1.0
Syntax:	XQuery
Comparison: XML and fragment comparisons are performed by serializing the results, re-parsing them, and using a custom deep-equal like function. This function currently ignores any attribute declaring namespace prefixes as well as text nodes that consist entirely of whitespace placed between element, comment or processing instructions nodes.
Other Comments: - As internal DTDs are not supported, the test source iddtd.xml has been changed to point to the external iddtd.dtd entity, removing the internal subset - The test suite has been executed with the 'reduced precision' flag that brings the precision of xs:decimal to 18 digits, xs:float to 8 digits, and xs:double to 17 digits

xbird/open

Date:	2006-08-21
Test Suite Version:	1.0.0 dev (rev 1.28)
Syntax:	XQuery
Transformation: Input queries have been run without any transformations.
Comparison: XML: XML comparison is done by using XMLUnit's assertXMLEqual method. Fragment: Fragment comparisons are performed by preparedly wrapping the reference results with a dummy element node, and the comparison method is same as XML comparison. Text: Text comparison is done by comparing String equality. Inspect: Inspect comparison is done by as same as Fragment comparison. But that, only non-failed tests are recorded as "pass", otherwise treated as "not tested". Most Inspect comparation requires human eye checking, so most tests are recorded as "not tested" actually.
Other Comments: XBird/open is yet under the heavy development and XQTS success rate is improving gradually. The initial release of XBird/open is scheduled at September, 2006. The XBird project is sponsored by Information-technology Promotion Agency (IPA), Japan. Test-cases which require inspections are mostly skipped (denoted as "not tested"). JUnit test cases for each XQuery test cases were generated by own code generator respectively. The detailed results are put on our project site.

X-Hive/DB

Date:	2006-10-30+01:00
Test Suite Version:	1.0.2
Syntax:	XQuery
Transformation: Input queries have been run without any transformations. Location hints have been added to schema and module import statements.
Comparison: Comparison of XML and Fragment results has been done white space ignorant.

xq2xsl

Date:	2006-10-26
Test Suite Version:	1.0.2 dev
Syntax:	XQuery
Transformation: No transformations are made directly on the XQuery file, however after conversion to XSLT, the parameters corresponding to external $input-context variables are changed from having empty default definitions to having definition "doc(relative/path/to/input/fileas/specified/in/catalogue)".
Comparison: XML: The result is not serialised. The expected result is parsed using doc() and compared using deep-equal(), if this fails, text nodes are normalized with normalize-space(), then deep-equal() is retried (Use of normalize-space is noted in the comment field in this case). Fragment: The result is not serialised. The expected result is wrapped in an element node so it can be parsed by am XML parser, the child nodes of this element are then compared using deep-equal (and optionaly normalize-space, as for the XML comparision). Text: is treated as a synonym for the Fragment comparison Inspect: If these have been looked at, they are declared pass, otherwise declared not tested. Errors are currently NOT compared. If (any) error is expected, (any) error raised is considered to be a test pass. (Due to limitations of the test harness: This should be fixed in time for a future version of the test suite.)
Other Comments: The xq2xsl transformation process is designed to only require a basic XSLT2 engine however the generated XSLT code may require a schema-aware XSLT engine to process some constructs. This test uses the same XSLT engine to transform the Query to XSLT and to execute the generated XSLT. The system used was SAXON 8.8 from Saxonica, for which the value of xsl:is-schema-aware is no.

XQuantum

Date:	2007-08-08
Test Suite Version:	1.0.2
Syntax:	XQuery
Transformation: External variables are initialized using statements of the form: declare variable $input-context := doc("name.xml");
Comparison: Test results were compared as specified in the XQTS Guidelines.
Other Comments: XQuantum supports XQuery over large XML datasets, implements static typing, and includes XQuery full-text extensions. Only test cases that passed static type checking were run. One hundred and eight test cases were found to be statically incorrect and are reported as "not tested" in the test results.

Anonymous

Date:	2006-10-30
Test Suite Version:	1.0
Syntax:	XQueryX
Transformation: External variables are initialized using statements of the form: declare variable $input-context := doc("name.xml");
Comparison: XML and fragment comparisons are performed by re-parsing the results with a custom tool, then performing a binary comparison.

xq2xsl

Date:	2006-10-26
Test Suite Version:	1.0.2 dev
Syntax:	XQueryX
Transformation: This is a trivial xqueryx implementation, simply prepending a call to the normative xqueryx stylesheet onto the test harness used by the xq2xsl XQuery implementation.
Comparison: XML: The result is not serialised. The expected result is parsed using doc() and compared using deep-equal(), if this fails, text nodes are normalized with normalize-space(), then deep-equal() is retried (Use of normalize-space is noted in the comment field in this case). Fragment: The result is not serialised. The expected result is wrapped in an element node so it can be parsed by am XML parser, the child nodes of this element are then compared using deep-equal (and optionaly normalize-space, as for the XML comparision). Text: is treated as a synonym for the Fragment comparison Inspect: If these have been looked at, they are declared pass, otherwise declared not tested. Errors are currently NOT compared. If (any) error is expected, (any) error raised is considered to be a test pass. (Due to limitations of the test harness: This should be fixed in time for a future version of the test suite.)
Other Comments: The xq2xsl transformation process is designed to only require a basic XSLT2 engine however the generated XSLT code may require a schema-aware XSLT engine to process some constructs. This test uses the same XSLT engine to transform the Query to XSLT and to execute the generated XSLT. The system used was SAXON 8.8 from Saxonica, for which the value of xsl:is-schema-aware is no.

(See 2 Sequence Normalization) Anglo-DT:    not specified BaseX:    Normalized / accessable as Java object Berkeley DB XML:    not specified DataDirect XQuery:    Not applicable, DataDirect XQuery doesn't support any implementation-defined output method. eXist-db:    not specified Galax:    not specified Qexo:    not specified Qizx:    none Saxon-SA:    Sequences are always normalized to documents before the serializer is invoked. However, the Java application may change the way in which a result sequence is converted to a document before invoking the serializer. Sedna XML Database System:    Only steps 1 and 2 Sequence Normalization are performed Stylus Studio:    not specified xbird/open:    Sequences are returned as Java Iterators, and Serialization is left to the user though a default toString() method is provided. X-Hive/DB:    Sequences are returned as Java Iterators over an X-Hive specific mapping of the XQuery type system to a Java object hierarchy. Serialization is left to the user, though a default toString() method is provided and returned XML nodes implement org.w3c.dom.Node, so they can be used with DOM serializers. xq2xsl:    Depends on underlying XSLT engine, in this case: SAXON 8.8 from Saxonica XQuantum:    not speci
