This script gets skipped when Protocol and Encoding/Protocol TCP Binary UA Security/ is enabled.
The problem is that this test case overwrites the available endpoints here:

Protocol and Encoding/Protocol TCP Binary UA Security/Test Cases/initialize.js:
if( gServerCapabilities.Endpoints !== null && gServerCapabilities.Endpoints.length > 0 ) {
for( var e=0; e<gServerCapabilities.Endpoints.length; e++ ) { // iterate thru all endpoints
var currentEP = gServerCapabilities.Endpoints[e];
if( currentEP.SecurityMode == MessageSecurityMode.SignAndEncrypt ) {
if( currentEP.SecurityPolicyUri == SecurityPolicy.policyToString( SecurityPolicy.Basic128Rsa15 ) ) {
endpointBas128 = currentEP;
}
else if( currentEP.SecurityPolicyUri = SecurityPolicy.policyToString( SecurityPolicy.Basic256 ) ) {
endpointBas256 = currentEP;
}
}
}//for e...
}
else {
addError( "No secure endpoints available. Aborting tests." );
stopCurrentUnit();
}

See the "else if" condition uses = instead of ==
