如何为这些类型的方法编写单元测试? [英] How to write unit test for these type of methods?

问题描述

我是单元测试的新手.如何为这些类型的方法编写单元测试?

I'm new to unit testing . How to write unit test for these type of methods?

 private boolean fn(Vertex vertex) {
        return vertex.id().toString().split(":").length > 1;
    }

此处Vertex是gremlin查询的元素. 我试图创建图的实例并将新的Vertex对象传递给该函数，但不起作用. 即

Here Vertex is the element of gremlin query . I have tried to create instance of graph and pass a new Vertex object to the function but not working . i.e

Vertex vertex = (Vertex) graphTraversalSource.addV("Test").property(id,"Profile:TEST");

有人可以建议测试这些类型方法的方法吗?

Can anyone suggest the ways to test these types of method?

推荐答案

您已经问过有关单元测试"的问题，但您的问题似乎确实与原因有关:

You've asked your question about "unit testing" but your question really seems to be about why:

Vertex vertex = (Vertex) graphTraversalSource.addV("Test").property(id,"Profile:TEST");

不允许您创建可以测试的Vertex.我想说的最明显的问题是，您没有

doesn't let you create a Vertex that you can test. I'd say the most obvious problem is that you didn't iterate your traversal in any way. In this case you need to call next():

Vertex vertex = (Vertex) graphTraversalSource.addV("Test").property(id,"Profile:TEST").next();

当然，对于要测试的fn(Vertex)函数，在图形数据库中创建实际的Vertex并没有多大意义-您可以只使用org.apache.tinkerpop.gremlin.structure.util.detached.DetachedVertex并执行以下操作:

Of course, for your fn(Vertex) function that you want to test, I don't see much point in creating an actual Vertex in a graph database - you could instead just use org.apache.tinkerpop.gremlin.structure.util.detached.DetachedVertex and do:

Vertex vertex = new DetachedVertex("Profile:TEST", "Test", null);

然后将其传递给您的函数进行测试.

and then pass that to your function to test.
