如何在Postman中声明空值？

Question

How can I assert null values in Postman. I know i should assert the "non-null" values and I'm doing this as well.

Here is my code:

 pm.test("Validate Approval is correct", function(){
if(IsEx === 1){
   pm.expect(data.Approval).not.eql(null);
}else if (IsEx ===0){
   pm.expect(data.Approval).equal(null);
   //pm.expect(data.Approval).eql(null);
   //pm.expect(data.Approval) === null;
   //pm.expect(data.Approval).include(null);
}
});

Basically the value approval is dependent on IsEx, I shouldn't be needing to check the null values, but in this case i need to. The problem I'm getting is "AssertionError: expected null to not deeply equal null".

Answer 1

you can use

pm.expect(data.Approval).to.be.undefined;

or

pm.expect(data.Approval).to.be.null;

depending on your needs.

You can also take a look at the chai reference for this topic .
