001

 CTT Browse()  Full browse of a valid node, without filters, view=null, browseDirection = Both, requestedMaxReferencesPerNode = 0, referenceTypeId = null, nodeClassMask = 0xFF, resultMask = 0x3F. Service result = Good. Operation result = Good . One element in results[]; browsed references in results[0] are correct - which means that all references have been returned (forward and reverse).

002

 CTT Browse()  Browse the same node as in (001) with browseDirection = Forward.
If there are no forward or no inverse references on the node, a different node must be used to complete this test.		 Service result = Good. Operation result = Good. Browsed references in results[0] must match the forward references in the result from (1).

003

 CTT Browse()  Browse the same node as in (001) with browseDirection = Inverse.
If there are no forward or no inverse references on the node, a different node must be used to complete this test.		 Service result = Good. Operation result = Good. Browsed references in results[0] must match the inverse references in the result from (1).

004

 CTT Browse()  Browse the same node as in (001) with referenceTypeId set to a valid ReferenceType NodeId and includeSubtype = false.
If the node has no references of the specified type, or no references that differ from the specified type, a different node must be used to complete this test.		 Service result = Good. Operation result = Good. All references in results[0] must be of the requested type (and all references of the requested type should be returned unless there were too many). The order of the references may appear sorted or not.

005

 CTT Browse()  Browse the same node as in (001) with referenceTypeId set to a valid ReferenceType NodeId and includeSubtype = true.
If the node has no references of the specified type, or no references that differ from the specified type or its subtypes, a different node must be used to complete this test.		 Service result = Good. Operation result = Good. All references in results[0] must be of the requested type or requested type`s subtype (and all references matching that criteria should be returned unless there were too many). The order of the references may appear sorted or not.

006

 CTT Browse()  Browse the same node as in (1) with nodeClassMask set to each defined nodeClass (except 128, Views; see test 18).
If the node has no references of the selected nodeClass or has references of only one nodeClass, a different node must be used to complete this test.		 Service result = Good. Operation result = Good. Only references of the selected nodeClass are returned.

007

 CTT Browse()  Specify multiple (valid) nodes to browse. Service result = Good. Operation results are Good. The number of results[] matches the number of nodesToBrowse[]. The references in each result are correct.

008

 CTT Browse()  Specify multiple nodes to browse, including valid and invalid nodes. Invalid nodes must include a node with invalid syntax in the nodeId, a node not in the address space, a referenceTypeId that has invalid syntax, and a referenceTypeId that does not exist. Service result = Good. Valid nodes have operation results of Good. Invalid nodes have bad operation results of appropriate error (see error test cases below).

009

 CTT Browse()  Browse the same node as in (001) with nodeClassMask=0. Service result = Good. Operation result = Good. Browsed references in results[] match the results of (1).

010

011

 Lab Browse()  Browse the same node as in (001) with a valid view. The view defines references that are Forward on the nodeToBrowse, and the view defines references that are Inverse on the nodeToBrowse. Service result = Good. Operation result = Good . Browsed references in results[] includes only those references that are defined in the view.

012

 Lab Browse()  Browse the same node as in (001) with a valid view. None of the references defined in the view are on the nodeToBrowse (in any direction). Service result = Good. Operation result = Good. The reference list in results[0] is empty.

013

 Lab Browse()  Browse the same node as in (001) with a valid view and requestedMaxReferencesPerNode = 1. The view defines multiple references that are on the nodeToBrowse (in either direction).

Within the loop, the service result = Good. The operation result = Good and the ContinuationPoint is not null. Check for resource leaks (the unused ContinuationPoints should be freed).

015

 CTT Browse()  Browse the same node as in (001) with referenceTypeId set to a valid ReferenceType NodeId and includeSubtype = false.
The specified reference type must have at least one subtype.
If the node has no references of one of the specified type`s subtypes, or no references that differ from the specified type`s subtypes, a different node must be used to complete this test.

Service result = Good. Operation result = Good. All references in results[0] must be of the requested type or requested type`s subtype (and all references matching that criteria should be returned unless there were too many). The order of the references may appear sorted or not.

017

 CTT Browse()  Browse the same node as in (1) with nodeClassMask set to 128 (Views).
If the node has no Views, a different node must be used to complete this test.
If the server has no views, this test passes without needing to be run.		 Service result = Good. Operation result = Good. Only View references are returned.

018

 CTT Browse()  Browse for a node of each node class. Each node, but for one exception, should return a non-null value for all Reference Description fields.
Nodes that are not class Object or Variable should return a null TypeDefinition.

0x07: ReferenceType & IsForward & NodeClass
0x39: ReferenceType & BrowseName & DisplayName & TypeDefinition
0x1A: IsForward & BrowseName & DisplayName
0x24: NodeClass & TypeDefinition		 Service result = Good. Operation result = Good. Only the specified ReferenceDescription fields are returned.

020

Client timeout settings must be configurable. The Server's address space will need to be large with a single folder containing hundreds or thousands of nodes.
Step #
Action
Expected Result(s)

1

If the Server is unable to process the request before the timeout, then it responds with a Good/empty response and a continuation point.

2

<p> If a continuation point is received then pass it into a BrowseNext function.</p>

Will accept: Results=0; ContinuationPoint=provided Results=>0; No ContinuationPoint Results=>0; ContinuationPoint provided. Not acceptable: Results=0; No ContinuationPoint and no error.

030

 Lab UA 1.04  Browse for nodes specifying a NodeClass filter, where the nodes are known to exist on a Remote server. Repeat the test for each NodeClass. Server must be connected to a remote server, otherwise skip the test. Server will return the nodeIds of those nodes whose NodeClass is not known, regardless of the filter.
