Formal requirement specification (Alloy model)

Mainly based on the course homework #1 and #2 of CIS771, software specification, taught by Dr.Hatcliff

Domains: ComponentSchema, PortSchema, PortType, EventType,

InterfaceType, ComponentInstance, PortInstance Relations among:

Component Schema & Component Instance Component Schema & Port Schema Port Schema & Port Type Connections & Port Types, Port Instances, Component Instances …

Operations: Create a componentInstance, Dispose a ComponentInstance, Disconnect

two PortInstances, Connect Source & Sink, Connect Facet & Receptacle

Formal requirement specification detail

ModalSP Example

Modeling Component Schemas

ComponentSchemasig ComponentSchema {schemaPorts: set

PortSchema} PortSchema

sig PortSchema { ptype: PortType, schemaPortOf: ComponentSchema}

Facet, receptacle, source, sinkpart sig Facet, Receptacle, Source, Sink extends

PortSchema {} PortType

sig PortType {} Event, interface

part sig EventType, InterfaceType extends PortType {}

Modeling Component Instances

ComponentInstancesig ComponentInstance {}

PortInstancesig PortInstance {}

Global State

sig State {setComponentInstances : set ComponentInstance,

setPortInstances : set PortInstance,componentInstanceOf : ComponentInstance -> ?ComponentSchema,componentInstances : ComponentSchema? ->ComponentInstance,portInstanceOf : PortInstance -> ?PortSchema,

portInstances : PortSchema? -> PortInstance,instancePorts : ComponentInstance? -> PortInstance, instancePartOf: PortInstance -> ?ComponentInstance,connection : PortInstance -> PortInstance

}{…}

Relations among Schemas and Instances

Each port instance pi of a component instance ci has a corresponding port schema ps in the component schema cs associated with ci.all ci : setComponentInstances | all pi : instancePorts[ci] |

portInstanceOf[pi] in (componentInstanceOf[ci]).schemaPorts

Each port schema ps declared in a component schema cs must have a corresponding port instance pi in every component instance ci of cs.all ci : setComponentInstances |all ps : (componentInstanceOf[ci]).schemaPorts

| one pi : portInstances[ps] | instancePartOf[pi]

Modeling Connections Connection relation should be symmetric

all pi1 : setPortInstances |all pi2 : connection[pi1] | (pi1 in connection[pi2])

Connections must be made between different component instances, i.e., a component instance cannot connect to itself. all pi : setPortInstances |

all p: connection[pi] |not instancePartOf[pi] = instancePartOf[p]

Each connection must only connect to things of the same typeall pi : setPortInstances |

(some connection[pi] => all p: connection[pi] | (portInstanceOf[pi].ptype = portInstanceOf[p].ptype))

Operations - Disconnect fun Disconnect(pi1,pi2: PortInstance, s,s':

State) { //pre condition

(pi2 in s.connection[pi1]) && (pi1 in s.connection[pi2]) //post condition

(not pi2 in s'.connection[pi1]) && (not pi1 in s'.connection[pi2])

//frame conditions.setPortInstances = s'.setPortInstances s.setComponentInstances = s'.setComponentInstancesall ci: s.setComponentInstances |

s.componentInstanceOf[ci] = s'.componentInstanceOf[ci]all pi: s.setPortInstances |

(s.portInstanceOf[pi] = s'.portInstanceOf[pi]) && (s.instancePartOf[pi] = s'.instancePartOf[pi])

all pi: s.setPortInstances - pi1 - pi2 |s.connection[pi] = s'.connection[pi]

} run Disconnect for 4

Test cases Small examples to test each aspect of

functionality Visit component instances but no connections among

them Only data connections exist Only basic event connection exist Only correlated event connection exist Three kinds of connections exist at the same time Error messages Test case examples
