@yangxk1 Do we need to consider the adjacency list when deleting a vertex/edge? where do you test addVertex() in GraphInfo.java ?

Do we need to consider the adjacency list when deleting a vertex/edge?

Do you mean that delete adjacency list in edgeInfo?

where do you test addVertex() in GraphInfo.java ?

I don't think we tested addVertex, can you add tests for them in GraphInfoTest/EdgeInfoTest/VertexInfoTest by the way?

Ok, where is the yaml file, to load a sample testing graph from which i can add or remove vertex and validate?

In GraphInfoTest::setup, a GraphInfo has been loaded and parsed, you can test method by it. https://github.com/apache/incubator-graphar/blob/b7768ad09ece6941a32e65e436f765fdf3c1a0fc/maven-projects/info/src/test/java/org/apache/graphar/info/GraphInfoTest.java#L39
