Table of Contents

1 Introduction

This document describes the test cases developed by the Rule Interchange Format (RIF) Working Group in accordance with the Working Group's Charter. The sections below delineate the scope of the test cases, explain their limits in determining conformance, and present the different types of tests and the format in which they are represented.

The test cases are maintained in the RIF Test Repository, and the normative test suites can be downloaded from there. Formatted copies of all test cases in the repository, plus additional tests that have not yet been fully processed by the Working Group, can be viewed at the RIF Test Collection Site.

This set of test cases is intended to enable an empirical investigation of RIF implementations. They can help identify problems both with the software developed to implement RIF specifications and with the specifications themselves. A widely used test suite providing good coverage of the target RIF dialect makes it more likely that different implementations will interoperate correctly.

The format of the tests is designed to be suitable for use by RIF implementers using test harnesses. Developers will need to write their own test harnesses, and are encouraged to report their results as well as any problems they encounter with the tests.

If additional test cases are contributed to the W3C, the Consortium may add them to the set of RIF test cases.

1.1 Scope

This document introduces the test cases for the RIF Core Dialect, Basic Logic Dialect (BLD) and Production Rule Dialect (PRD), as well as for RIF-RDF and RIF-OWL combinations as specified in RIF RDF and OWL Compatibility. The current set of tests focuses on testing syntax, entailment and validity of import directives, as described in the Test Types section. Additional types of tests may be added in the future.

The test suite contains tests for RIF consumers as defined in the RIF-Core Conformance Clauses, RIF-BLD Conformance Clauses, and the RIF-PRD Conformance Clauses, but not for RIF producers. Producer tests are not included since producers translate from a particular rule language into RIF, and specifying tests to verify this translation without referring to specific rule languages would be difficult. However, partial syntactic validation of documents generated by producers can be performed using the XML schema for the target dialect (Core XML Schema, BLD XML Schema, or PRD XML Schema). For implementations that are both producers and consumers, some validation of the producer can be achieved by translating an entailment test from RIF to the target rule language, then back to RIF, then again to the target rule language, and then executing the entailment test.

The tests are designed to:


The test suite is not exhaustive: it does not completely cover the RIF specification.

1.2 Conformance

Conformance is defined as the fulfillment of specified requirements, which are detailed in the conformance clause of a specification. (See QA Framework specification Guide.) Admissable RIF documents, and conformant RIF consumers and producers are defined in the conformance clauses section of the relevant specification: RIF-Core Conformance Clauses, RIF-BLD Conformance Clauses, and RIF-PRD Conformance Clauses. A complete conformance test suite would be a set of test cases that cover this set of requirements, such that passing all the tests in the suite for a particlar RIF dialect indicates conformance to that dialect. However, the development of this type of comprehensive test suite is beyond the scope of the Working Group, and the RIF test cases do not constitute complete conformance test suites. Failure to pass all the tests in the suite indicates that the implementation does not meet the relevant specification. But passing all the tests in the suite indicates only that the implementation is conformant to that particular version of the test suite.

2 Deliverables

The RIF test package consists of:

3 Test Types

This section introduces a categorization of the tests included in the test suite. Each test case describes inputs that can be provided to a RIF processor, and specifies the behavior required to satisfy the conformance conditions in that situation. There are several different types of test cases detailed in the following sub-sections. The type of test determines the task, associated inputs, and expected outcome of the test.

3.1 Syntactic Tests

Syntactic tests validate a RIF consumer's recognition of an admissible RIF XML document. An admissible RIF document conforms to all the syntactic constraints of the relevant dialect, including those that cannot be checked with XML Schema validation.

3.1.1 Positive Syntax Tests

These tests involve a single RIF document, indicated by the InputDocument element in the manifest for the test. The document is a syntactically correct RIF document in each dialect indicated by a dialect element in the manifest.

The test is passed if the processor indicates that the document is syntactically correct, and failed otherwise.

Note that the premises of all positive and negative entailment tests (defined below) are syntactically correct RIF documents and so can be used as positive syntax tests.

Note also that a positive syntax test for a given dialect D is also a positive syntax test for any dialect that extends D. For dialects defined by the RIF Working Group, each dialect that a test applies to is indicated explicitly with a dialect element in the manifest.

3.1.2 Negative Syntax Tests

These tests involve a single RIF document, indicated by the InputDocument element in the manifest for the test. The document is not a syntactically correct RIF document in each dialect indicated by a dialect element in the manifest.

The test is passed if the processor indicates that the document is syntactically incorrect, and failed otherwise.

Note that a negative syntax test for a given dialect D is also a negative syntax test for any dialect that restricts D. For dialects defined by the RIF Working Group, each dialect that a test applies to is indicated explicitly with a dialect element in the manifest.

3.2 Import Rejection Tests

Import rejection tests check a RIF consumer's recognition of an invalid imported document set. For RIF-RDF and RIF-OWL combinations, invalid import scenarios are specified in the Interpretation of Profiles section of the RIF RDF and OWL Compatibility document. For Core, BLD or PRD documents, import directives can result in a document set that doesn't satisfy the Core well-formedness, BLD well-formedness or PRD well-formedness requirements.

Each test of this type includes a RIF document, indicated by the InputDocument element in the manifest for the test, and one or more documents in the imports closure of the input document, indicated by ImportedDocument elements.

The test is passed if the processor indicates that the input document is rejected, and failed otherwise.

Note that an import rejection test for a given dialect D is also an import rejection test for any dialect that extends D. For dialects defined by the RIF Working Group, each dialect that a test applies to is indicated explicitly with a dialect element in the manifest.

3.3 Semantic Tests

These tests validate a RIF processor's computation of the entailment relation. Each entailment test has one or more associated dialects, and is of the general form

Premises
R
Conclusion
C

Where R is a RIF document, C is a RIF condition, an RDF document or an OWL document, and the imports closure of R entails (for positive entailment tests) or does not entail (for negative entailment tests) C in the given dialects. The conclusions of semantic tests are defined to be RIF conditions because RIF Conformance is defined in terms of the entailment of closed RIF condition formulas. The complete specification of these tests is given in the sub-sections below.

Note that a positive or negative entailment test for a given dialect D also applies to any dialect that extends D. For dialects defined by the RIF Working Group, each dialect that a test applies to is indicated explicitly with a dialect element in the test's manifest.


3.3.1 Positive Entailment Tests

Each test of this type includes a premises document, indicated by the PremiseDocument element in the manifest for the test, a conclusion document, indicated by the ConclusionDocument element, and optionally one or more documents in the imports closure of the premises document, indicated by ImportedDocument elements. Note that the conclusion document is a RIF condition.

The applicable entailment regimes are indicated by dialect elements in the manifest file:

In addition, an optional Combinations element in the manifest indicates the types of documents in the imports closure of the premises document.


Note that, in general, the conclusion will not include everything that is entailed by the premises.

A conformant RIF consumer should report that the conclusion is entailed by the premises, should not report that the answer is undecided, and must not report that the conclusion is not entailed by the premises.

3.3.2 Negative Entailment Tests

Each test of this type includes a premises document, indicated by the PremiseDocument element in the manifest for the test, a conclusion document, indicated by the NonConclusionDocument element, and optionally one or more documents in the imports closure of the premises document, indicated by ImportedDocument elements.

The applicable entailment regimes are indicated by dialect elements in the manifest file:

In addition, an optional Combinations element in the manifest indicate the types of documents in the imports closure of the premises document.

A conformant RIF consumer should report that the conclusion is not entailed by the premises, should not report that the answer is undecided, and must not report that the conclusion is entailed by the premises.

4 Test Case Format

Each test case has an associated manifest file that contains information needed to property execute the test. These files are in a machine-readable XML format in order to enable the development of automated testing frameworks. The information in the manifests can be used to select tests according to a variety of criteria, such as what dialect they apply to, and to locate the documents that participate in the test.

The format of the test cases follows the general guidelines of the W3C QA Working Group's [Test Metadata Note]. The RIF test case schema is given in rif-testcase.xsd.

This section presents a summary of the data elements, organized by the type of test to which they apply. The name of the root element of a test case document indicates the test type:

The root element has two attributes:

4.1 Properties of All Tests

4.1.1 status

The value of this property is the status of the test case according to the test case approval process. Values of this property are one of an enumerated list: Proposed, Approved, Rejected or Obsolete.

This is a required element, and there is one for each test.

4.1.2 dialect

This property is used to indicate the RIF dialects that the test applies to. There is one 'dialect' element for each dialect that the test is valid for. The possible dialect values are Core, BLD and PRD.

This is a required element, and there are one or more for each test.

4.1.3 purpose

The value of this property is a brief explanation of the purpose of the test, suitable for display in tabular format.

       we have that ex:a rdf:type ex:D must hold and by the semantics of combinations, we have that
       ex:a rdf:type ex:D implies ex:a # ex:D. Therefore, ex:a # ex:D is derived.

5 Test Case Repository

The test cases are available from the Test Case Repository where they are each in an individual sub-directory named for the test case. The test cases are also available in dialect test suites as zip files. These zip files expand into a directory structure organized by status and test type. There is also a manifest file for each dialect (CoreTests.xml, BLDTests.xml, PRDTests.xml) that describes all the tests applicable to the dialect.

6 Running the Test Cases

The test suite is intended for use on a variety of rule systems, each with its own API. Therefore, the tasks of providing input to the rule engine in a system-dependent manner and of checking that the results are correct are left to the tester. The manifest contains a machine-readable description of the test cases, and is intended to enable automated processing of the test cases.

Users are expected to write their own test harnesses to carry out the following tasks:

The dialect and Combinations elements in the manifest file can be used to filter for appropriate tests. For example, a RIF-BLD implemention should select only tests that have a dialect property with a value of BLD, and implementations that don't support RIF-OWL combinations should skip tests that have a Combinations element containing profile sub-elements with a value of one of the OWL profiles.

6.1 Test Case Customization

Testers have the option of making certain changes to the test cases in order to facilitate use of the test suite. All changes made to the original test suite should be documented in free-text form as part of the results submission. Acceptable changes are described below.

6.1.1 Customizing Import Directives

For tests with input documents that contain import directives, the location of the imported document specified in the directive will be at the W3C website, and the imported document will be made available at that location. Test cases will also include all imported documents as part of their data (in the zip file), pointed to by elements in the manifest. Users who wish to access these files in their own environment can change the import directives in the input documents to reflect the updated location.

6.2 Reporting Test Results

Implementers are encouraged to report their test results by e-mail with a subject of "RIF Test Results" to [email protected] (which has a public archive); the results will be summarized on the RIF Test Results page. This information will help to determine when the RIF specifications are ready to become W3C Recommendations.

The results should be formatted in XML according to rif-test-report.xsd. The requested information is described below, and an example test report is given at the end of this section.

6.2.1 Test Report fields

6.2.1.1 Implementation

There is one Implemention element per report. This information identifies the software that was tested.

6.2.1.2 Test Run

There is one TestRun element per report.

6.2.1.3 Test Result

There is one or more TestResult elements per report, one for each test case executed. If a test case is found to be in error, don't submit a test result for it, but rather report the bug as described the Reporting Problems section

6.2.2 Example Test Report

6.3 Reporting Problems

If you believe that a test case is incorrect please send a bug report to [email protected]. Please be specific about the problem you are reporting. Clearly identify the test case or test cases that are problematic and include the repository version, which can be found in the version.txt file in the RIF Test Case repository. If you believe that the expected result is wrong, then tell us what you believe the expected result should be. Please cite portions of one or more of the RIF specifications to support your position whenever possible.
