Postman: How to check whether the field is returning null in the Postman automation
提问by Tester77
I have tried with "!== null", but it is returning PASS even when the field is returning 0 or "".
我曾尝试使用“！== null”，但即使该字段返回 0 或“”，它也会返回 PASS。

Did you try
你试过了吗
pm.expect(response.your_field).to.eql(null);
?
?

This works as of Mar-2019:
这适用于 2019 年 3 月：
pm.test("To Check if Value is Null", function() {
var jsonData = pm.response.json();
pm.expect(jsonData.<yourfield>).not.eq(undefined);
)};

If you are checking the Id of the first item returned in a list, you could use not.equal(null):
如果您正在检查列表中返回的第一项的 Id，您可以使用not.equal(null)：
pm.expect(pm.response.json().value[0].Id).not.equal(null);
Note that the word "equal" is fully spelled out, although the shortened "eql" does work.
请注意，尽管缩写的“eql”确实有效，但“equal”一词已完整拼写。

try this one:
试试这个：
pm.test("your-value is not null", function () {
var jsonData = pm.response.json();
pm.expect(jsonData.your_value).not.eql(null);
});

Postman doesn't reference non-existent paths as null, but as undefined.
Postman 不会将不存在的路径引用为 null，而是将其引用为未定义。
pm.expect(JsonResponse.FAKE.PATH).not.eql(undefined);
This test should fail, as this fake json path is actually undefined.
这个测试应该会失败，因为这个假的 json 路径实际上是未定义的。

I faced similar issue. But checking it in following way worked for me
我遇到了类似的问题。但是按照以下方式检查它对我有用
tests["Item is not null"] =
jsonData.item !== undefined;

You gotta place the + [i] after the function you gonna validate on the tests[] so only it will return valid statements on each array. For example,
你必须将 + [i] 放在你要在测试 [] 上验证的函数之后，这样它才会在每个数组上返回有效的语句。例如，
function checkIsNull() {
var items = json.data.pois.items
var PlaceIdIsNull = true;
var subTypeExtraIsNull = true;
var websiteIsNull = true;
for (var i = 0; i < items.length; i++) {
if (items[i].placeId !== null) {
PlaceIdIsNull = false;
}
if (items[i].subTypeExtra !== null) {
subTypeExtraIsNull = false;
}
if (items[i].website === null) {
websiteIsNull = false;
tests['website is null only happened on these arrays' + [i]] = true;
}
tests['Place ID is null '] = PlaceIdIsNull
tests['subTypeExtra is null '] = subTypeExtraIsNull
}
}
checkIsNull();
Result:
结果：
PASS Place ID is null
PASS 地点 ID 为空
PASS subTypeExtra is null
PASS subTypeExtra 为空

You can access response json like :
您可以访问响应 json，如：
var json = JSON.parse(responseBody);
var yourVAr = json.yourVar
if(yourVar == null){
//your var is null here
}

I have done similar, this is one part of the code and its works well Check this code
我做过类似的，这是代码的一部分，它运行良好检查此代码
var jsonData = JSON.parse(responseBody);
for(i=0; i<jsonData.data.length; i++){
tests["due date is between given date range"] = jsonData.data[i].duedate < environment.Cenddate && jsonData.data[i].duedate > environment.Cstartdate;
tests["response body has department name"] = jsonData.data[i].department.name !== null;
}
回答by John Meyer
How about:
怎么样：
var jsonData = JSON.parse(responseBody);
tests["Item is not null"] =
jsonData.item !== null &&
jsonData.item !== ' ' &&
jsonData.item !== 0;
