This executable test suite (ETS) verifies the conformance of the implementation under test (IUT) with respect to the set of relevant specifications depicted in Figure 1. Conformance testing is a kind of “black box” testing that examines the externally visible characteristics or behaviors of the IUT while disregarding any implementation details.
Figure 1: Relevant specifications

Several conformance classes are defined in the principal specifications; the ones listed below are covered by this test suite:
The documents listed below stipulate requirements that must be satisfied by a conforming implementation.
If any of the following preconditions are not satisfied then all tests in the suite will be marked as skipped.
The test suite definition file (testng.xml) is located in the root package, org.opengis.cite.cat20.dgiwg10. A conformance class corresponds to a <test> element, each of which includes a set of test classes that contain the actual test methods. The general structure of the test suite is shown in Table 1.
| Conformance class | Test classes |
|---|---|
| Conformance Level 1 | org.opengis.cite.cat20.dgiwg10.level1.* |
| Conformance Level 2 | org.opengis.cite.cat20.dgiwg10.level2.* |
The Javadoc documentation provides more detailed information about the test methods that constitute the suite.
The test run arguments are summarized in Table 2. The Obligation descriptor can have the following values: M (mandatory), O (optional), or C (conditional).
| Name | Value domain | Obligation | Description |
|---|---|---|---|
| iut | URI | M | A URI that refers to the implementation under test or metadata about it. Ampersand ('&') characters must be percent-encoded as '%26'. |
| ics | A comma-separated list of string values. | O | An implementation conformance statement that indicates which conformance classes or options are supported. |
