PathAssert

protected PathAssert(org.neo4j.graphdb.Path actual)

Method Detail

getActual

public org.neo4j.graphdb.Path getActual()

startsWithNode

public PathAssert startsWithNode(org.neo4j.graphdb.Node node)

Verifies that the actual Path starts with the given node

Example:

 GraphDatabaseService graph = new TestGraphDatabaseFactory().newImpermanentDatabase();
 // [...]
 Relationship love = homerNode.createRelationshipTo(doughnutNode, DynamicRelationshipType.withName("LOVES"));
 // PathExpander bellyExpander = [...]
 Path homerToDoughnutPath = GraphAlgoFactory.shortestPath(bellyExpander, 2).findSinglePath(homerNode, doughnutNode);
 
 assertThat(homerToDoughnutPath).startsWithNode(homerNode);
 

If the node is null, an IllegalArgumentException is thrown.

Parameters:

node - the expected start node of the actual Path

Returns:

this PathAssert for assertions chaining

Throws:

IllegalArgumentException - if node is null.

AssertionError - if the actual Path does not start with the given node

doesNotStartWithNode

public PathAssert doesNotStartWithNode(org.neo4j.graphdb.Node node)

Verifies that the actual Path does not start with the given node

Example:

 GraphDatabaseService graph = new TestGraphDatabaseFactory().newImpermanentDatabase();
 // [...]
 Relationship love = homerNode.createRelationshipTo(doughnutNode, DynamicRelationshipType.withName("LOVES"));
 // [...]
 // PathExpander bellyExpander = [...]
 Path homerToDoughnutPath = GraphAlgoFactory.shortestPath(bellyExpander, 2).findSinglePath(homerNode, doughnutNode);

 assertThat(homerToDoughnutPath).doesNotStartWithNode(healthyPersonNode);
 

If the node is null, an IllegalArgumentException is thrown.

Parameters:

node - the expected start node of the actual Path

Returns:

this PathAssert for assertions chaining

Throws:

IllegalArgumentException - if node is null.

AssertionError - if the actual Path starts with the given node

endsWithNode

public PathAssert endsWithNode(org.neo4j.graphdb.Node node)

Verifies that the actual Path ends with the given node

Example:

 GraphDatabaseService graph = new TestGraphDatabaseFactory().newImpermanentDatabase();
 // [...]
 Relationship love = homerNode.createRelationshipTo(doughnutNode, DynamicRelationshipType.withName("LOVES"));
 // PathExpander bellyExpander = [...]
 Path homerToDoughnutPath = GraphAlgoFactory.shortestPath(bellyExpander, 2).findSinglePath(homerNode, doughnutNode);
 
 assertThat(homerToDoughnutPath).endsWithNode(doughnutNode);
 

If the node is null, an IllegalArgumentException is thrown.

Parameters:

node - the expected end node of the actual Path

Returns:

this PathAssert for assertions chaining

Throws:

IllegalArgumentException - if node is null.

AssertionError - if the actual Path does not end with the given node

doesNotEndWithNode

public PathAssert doesNotEndWithNode(org.neo4j.graphdb.Node node)

Verifies that the given node is not the last one of the actual Path

Example:

 GraphDatabaseService graph = new TestGraphDatabaseFactory().newImpermanentDatabase();
 // [...]
 Relationship love = homerNode.createRelationshipTo(doughnutNode, DynamicRelationshipType.withName("LOVES"));
 // PathExpander bellyExpander = [...]
 Path homerToDoughnutPath = GraphAlgoFactory.shortestPath(bellyExpander, 2).findSinglePath(homerNode, doughnutNode);

 assertThat(homerToDoughnutPath).doesNotEndWithNode(saladNode);
 

If the node is null, an IllegalArgumentException is thrown.

Parameters:

node - the expected last node of the actual Path

Returns:

this PathAssert for assertions chaining

Throws:

IllegalArgumentException - if node is null.

AssertionError - if the actual Path ends with this node

endsWithRelationship

public PathAssert endsWithRelationship(org.neo4j.graphdb.Relationship relationship)

Verifies that the given relationship is the last one of the actual Path

Example:

 GraphDatabaseService graph = new TestGraphDatabaseFactory().newImpermanentDatabase();
 // [...]
 Relationship love = homerNode.createRelationshipTo(doughnutNode, DynamicRelationshipType.withName("LOVES"));
 // PathExpander bellyExpander = [...]
 Path homerToDoughnutPath = GraphAlgoFactory.shortestPath(bellyExpander, 2).findSinglePath(homerNode, doughnutNode);
 
 assertThat(homerToDoughnutPath).endsWithRelationship(love);
 

If the node is null, an IllegalArgumentException is thrown.

Parameters:

relationship - the expected last relationship of the actual Path

Returns:

this PathAssert for assertions chaining

Throws:

IllegalArgumentException - if relationship is null.

AssertionError - if the actual Path does not contain this relationship last

doesNotEndWithRelationship

public PathAssert doesNotEndWithRelationship(org.neo4j.graphdb.Relationship relationship)

Verifies that the given relationship is not the last one of the actual Path

Example:

 GraphDatabaseService graph = new TestGraphDatabaseFactory().newImpermanentDatabase();
 // [...]
 Relationship love = homerNode.createRelationshipTo(doughnutNode, DynamicRelationshipType.withName("LOVES"));
 // PathExpander bellyExpander = [...]
 Path homerToDoughnutPath = GraphAlgoFactory.shortestPath(bellyExpander, 2).findSinglePath(homerNode, doughnutNode);

 assertThat(homerToDoughnutPath).doesNotEndWithRelationship(hate);
 

If the node is null, an IllegalArgumentException is thrown.

Parameters:

relationship - the expected last relationship of the actual Path

Returns:

this PathAssert for assertions chaining

Throws:

IllegalArgumentException - if relationship is null.

AssertionError - if the actual Path ends with this relationship

hasLength

public PathAssert hasLength(int length)

Verifies that the path length equals the given one

Example:

 GraphDatabaseService graph = new TestGraphDatabaseFactory().newImpermanentDatabase();
 // [...]
 Relationship love = homerNode.createRelationshipTo(doughnutNode, DynamicRelationshipType.withName("LOVES"));
 // PathExpander bellyExpander = [...]
 Path homerToDoughnutPath = GraphAlgoFactory.shortestPath(bellyExpander, 2).findSinglePath(homerNode, doughnutNode);
 
 assertThat(homerToDoughnutPath).hasLength(1);
 

If the length is strictly negative, an IllegalArgumentException is thrown.

Parameters:

length - the expected length of the Path

Returns:
