As of April 2020, this module is retiring. This means it will no longer be maintained and released together with new versions of the GraphAware Framework and Neo4j. The last compatible Neo4j version is 3.5.14.
Custom REST APIs on top of Neo4j have been practically replaced by Cypher User Functions and Procedures. If you need functionality similar to what RestTest provided, go ahead and write a procedure that uses GraphUnit.
This repository will remain public.
GraphAware RestTest is a simple library for testing code that talks to Neo4j running in standalone server mode.
You will need the GraphAware Neo4j Framework and GraphAware Neo4j RestTest .jar files (both of which you can download here) dropped
into the plugins directory of your Neo4j installation.
For the framework to work, you need to adjust your neo4j configuration as described in the framework installation instructions.
After Neo4j restart, you will be able to use the RestTest APIs.
Releases are synced to Maven Central repository.
The version number has two parts. The first four numbers indicate compatibility with Neo4j GraphAware Framework. The last number is the version of the RestTest library. For example, version 2.1.2.7.2 is version 2 of RestTest compatible with GraphAware Neo4j Framework 2.1.2.7.
RestTest allows you to assert the state of the database running in server mode and to clear it. It is in a sense equivalent to using GraphUnit in embedded mode.
When deployed in server mode, there are three URLs that you can issue POST requests to:
http://your-server-address:7474/graphaware/resttest/clearto clear your database. No body required.http://your-server-address:7474/graphaware/resttest/assertSameGraphto assert the state of the database. You need to provide a body described shortly.http://your-server-address:7474/graphaware/resttest/assertSubgraphto assert the state of the database. You need to provide a body described shortly.http://your-server-address:7474/graphaware/resttest/assertEmptyto assert the database is empty. You need to provide a body described shortly.
The body where required needs to provide a Cypher CREATE statement, representing the state of the database being asserted, for example:
{
"cypher": "CREATE (one:Person {name:'One'})-[:FRIEND_OF]->(two:Person {name:'Two'})"
}The second API call is used to verify that the graph in the database is exactly the same as the graph created by the Cypher CREATE statement provided in the body of the request. This means that the nodes, their properties and labels, relationships, and their properties and labels must be exactly the same. Note that Neo4j internal node/relationship IDs are ignored. In case the graphs aren't identical, the assertion fails and you will get a response with EXPECTATION_FAILED (417) status code. If the test passes, you will get an OK (200).
The third API call is used to verify that the graph created by provided Cypher statement is a subgraph of the graph in the database. Request body options and response codes are same as above.
Finally, the API call that ensures that the database is empty has the body as an optional requirement and, of course, no Cypher is required.
This module provides a set of Cypher procedures and functions that allows to call the methods from Cypher.
This procedure allows to clear your database. No parameter required. Example of usage:
CALL ga.resttest.clearDatabase();
This function allows to assert the state of the database. You need to provide a parameter described shortly. Example of usage:
RETURN ga.resttest.assertSameGraph("{ \"cypher\": \"...\"}") AS value;
This function is used to verify that the graph in the database is exactly the same as the graph created by the Cypher CREATE statement provided in the parameter. This means that the nodes, their properties and labels, relationships, and their properties and labels must be exactly the same. Note that Neo4j internal node/relationship IDs are ignored. In case the graphs aren't identical, the assertion fails and you will get false value. If the test passes, you will get a true value.
This function allows to assert a part of the database. You need to provide a parameter described shortly. Example of usage:
RETURN ga.resttest.assertSubgraph("{ \"cypher\": \"...\"}") AS value;
This function is is used to verify that the graph created by provided Cypher statement is a subgraph of the graph in the database. In case if the result of cypher is not identical of any subgraph of the database It will return false value. If it is a subgraph of the database you will get a true value.
This function allows to ensure that the database is empty. You can define a parameter described shortly or use with an empty string. Example of usage:
RETURN ga.resttest.assertEmpty("{ \"node\": \"...\"}") AS value;
If the database is not empty It will return false value. If it empty you will get a true value.
It is possible to use expressions to include/exclude certain nodes, relationships, and properties thereof from the comparisons.
For example, for the purposes of comparison, if we only wanted to include nodes labelled Person, relationships with type FRIEND_OF, and ignore any
timestamp properties on both nodes and relationships, the body of the POST request (or the parameter of the function) would look like this:
{
"cypher": "CREATE (one:Person {name:'One'})-[:FRIEND_OF]->(two:Person {name:'Two'})",
"node":"hasLabel('Person')",
"relationship":"isType('FRIEND_OF')",
"node.property":"key != 'timestamp'",
"relationship.property":"key != 'timestamp'"
