When I try to use a list of 14216 maps, this widget freezes for a few seconds during initialization:
List _list = [
{
"code": "110000000",
"region": "11",
"district": "0",
"locality_center": "0",
"locality": "0",
"ru_name": "Акмолинская область",
"kk_name": "Ақмола облысы"
},...];
#override
Widget build(BuildContext context) {
print('it takes a few seconds before this message is printed in terminal');
print(_list.length);
return Container();
}
Is there a better way of storing and using huge lists in flutter?

I would like to write a test in Postman that validates there are no duplicate values in the array of objects. Here is an example response:
This is my json response :
{
"content": [
{
"id": "88848990-c4c8-4e7d-b708-3e69e684085b",
"name": "UPDATED",
},
{
"id": "42c37e1d-eed3-4f5c-b76a-7b915c05b0bf",
"name": "Swoop ",
},
{
"id": "88848990-c4c8-4e7d-b708-3e69e684085b",
"name": "United Test Airlines",
},
I can see 2 ids that are the same I want to write a test in postman to identify any duplicates in my results. If the test picks up duplicates then it must fail, if it does not pick up any duplicates it should pass. Note I am new to postman api testing.
The short and esay solution might be:
Save all id in an array
Create a set from this array
Compare size of the array and the set. If it equals, then no duplication. If not, there is a duplication.
const res = pm.response.json();
const ids = _.map(res.content, "id");
pm.test("check duplicate id", () => {
const setIds = new Set(ids);
pm.expect(ids.length).eql(setIds.size);
})
I want to check response "class_type" value has "REGION".
I test springboot API using mockMvc.
the MockHttpServletResponse is like this.
Status = 200
Error message = null
Headers = {Content-Type=[application/json;charset=UTF-8]}
Content type = application/json;charset=UTF-8
Body =
{"result":true,
"code":200,
"desc":"OK",
"data":{"total_count":15567,
"items": ...
}}
this is whole response object.
Let's take a closer look, especially items.
"items": [
{
"id": ...,
"class_type": "REGION",
"region_type": "MULTI_CITY",
"class": "com.model.Region",
"code": "AE-65GQ6",
...
},
{
"id": "...",
"class_type": "REGION",
"region_type": "CITY",
"class": "com.model.Region",
"code": "AE-AAN",
...
},
I tried using jsonPath.
#When("User wants to get list of regions, query is {string} page is {int} pageSize is {int}")
public void userWantsToGetListOfRegionsQueryIsPageIsPageSizeIs(String query, int page, int pageSize) throws Exception {
mockMvc().perform(get("/api/v1/regions" ))
.andExpect(status().is2xxSuccessful())
.andDo(print())
.andExpect(jsonPath("$.data", is(notNullValue())))
.andExpect(jsonPath("$.data.total_count").isNumber())
.andExpect(jsonPath("$.data.items").isArray())
.andExpect(jsonPath("$.data.items[*].class_type").value("REGION"));
log.info("지역 목록");
}
but
jsonPath("$.data.items[*].class_type").value("REGION")
return
java.lang.AssertionError: Got a list of values ["REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION","REGION"] instead of the expected single value REGION
I want to just check "$.data.items[*].class_type" has "REGION".
How can I change this?
One option would be to check whether you have elements in your array which have the class_type equal to 'REGION':
public static final String REGION = "REGION";
mockMvc().perform(get("/api/v1/regions"))
.andExpect(jsonPath("$.data.items[?(#.class_type == '" + REGION + "')]").exists());
I am working on some test scripts and data cleanup scripts using postman, and was wondering if it were possible to run a request on an array result produced in a previous step.
For example, I have an API that returns tasks as a JSON like so:
[
{
"active": true,
"_id": "5b2101244651a04a4907b094",
"name": "Test Task",
"updatedAt": "2018-06-13T11:33:56.911Z",
"createdAt": "2018-06-13T11:33:56.911Z"
},
{
"active": true,
"_id": "5b2101244651a04a4907b067",
"name": "Test Task 2",
"updatedAt": "2018-06-13T11:33:56.911Z",
"createdAt": "2018-06-13T11:33:56.911Z"
}
]
So in the Tests scripts I run this to collect an array of the IDs:
var jsonData = JSON.parse(responseBody)
postman.setEnvironmentVariable('task_id_list', jsonData.map((i) => i._id))
The next request is to delete a task, but the API only deletes one at a time. I am trying to do something like:
http://localhost:3000/api/v1/tasks/{{task_id_list}}
I was hoping that Postman would see that task_id_list was an array and simple "work", but that doesn't seem to be the case. Is it possible to have a step run multiple times based on an array input?
Solution from this article
Get array of ID's in test script of first request (I prefer to store it in JSON to avoid bugs):
let JsonData = pm.response.json();
let iDs = JsonData.map((i) => i._id)));
pm.environment.set("IdArray", JSON.stringify(iDs);
//and now check, if there was no objects returned, stop runner
if(iDs.length === 0)
{
postman.setNextRequest(null);//next request will not be sent
}
else
{
pm.environment.set("count", 0);
}
In pre-request script of 2 request:
var count = +pm.environment.get("count");
var iDs = JSON.parse(pm.environment.get("IdArray"));
pm.variables.set("task_id_list", iDs[count]); //like one-request environment variable
count = count + 1; //next iteration
if(count < iDs.length)
{
postman.setNextRequest("NAME OF THIS REQUEST");
}
else
{
postman.setNextRequest(null); // or next request name
}
pm.environment.set("count", count)
So you should understand my idea.
I am trying to automize a registration scenario in postman using test scripts
I have the following JsonArray as a response:
[
{
"id": 1,
"name": "user_A",
"cntkp": "martin",
"company": "kreativ",
"tel": "12345678",
"email": "user_A#gmail.com"
"street": "str. 0001",
"city": "DEF",
}
......
......
......
{
"id": 4,
"name": "user_B",
"cntkp": "martin",
"company": "kreativ",
"tel": "12345678",
"email": "user_B#gmail.com"
"street": "str. 0002",
"city": "NJ",
}
......
......
......
{
"id": 10,
"name": "User_C",
"cntkp": "martin",
"company": "kreativ",
"tel": "12345678",
"email": "user_C#gmail.com"
"street": "str. 0003",
"city": "ABC",
}
......
]
the array length can be dynamic and changed (in this sample is 10) and want to find the object with special email (somewhere in the array) and then get the ID from that object and make the assertion based on JsonData from this object (catch elements e.g. check name).
how can I do that?
thanks for the support.
I send a GETrequest to get all Data from Registration DB.
as response I get a JsonArray
from Json Array I need the specific Object for the assertion (e.g. object with email user_B in sample) .
I know my Email address and base on it I have to findout the ID from Object .
I can do it when I know which ID is my ID but in case it is dynamic I don't know how to search an array for it in postman to get ID
For example, to assert the company name
pm.expect(jsonData[0].company).to.equal(pm.environment.get("regDB_new_company"))
but if I dont know the ID ( only know my email) I have first to find out the ID of Object then I can asser it.
e.g.
in this case first, find the object with email "user_B#gmail.com"
then from that object get ID element (in this case 4)
then I want to assert for all data from the object
Thanks Danny, I found the solution
var arr = pm.response.json()
for(i = 0; i < arr.length; i++) {
if (arr[i].email == "userB#gmail.com") {
pm.environment.set("personID", arr[i].id)
}
}
I'm creating a skill in Alexa that does the following.
User : Hi
Alexa, hello please give me your name
User : John
Alexa : Hi John, good to meet you. How old are you
User : 25
Below are my intents
{
"intents": [
{
"intent": "StartTheFlow",
"slots": [
{
"name": "custName",
"type": "list_of_userNames"
},
{
"name": "age",
"type": "AMAZON.NUMBER"
}
]
},
{
"intent": "AMAZON.HelpIntent"
},{
"intent": "Welcome"
},
{
"intent": "AMAZON.StopIntent"
},
{
"intent": "AMAZON.CancelIntent"
}
]
}
And below are my utterances
StartTheFlow Hi
StartTheFlow {custName}
StartTheFlow {age}
Below is my onIntent()
#Override
public SpeechletResponse onIntent(final IntentRequest request, final Session session) throws SpeechletException {
log.info("onIntent requestId={}, sessionId={}", request.getRequestId(), session.getSessionId());
Intent intent = request.getIntent();
String intentName = (intent != null) ? intent.getName() : null;
if ("StartTheFlow".equals(intentName)) {
return getTheFlow(intent, session);
} else if ("AMAZON.HelpIntent".equals(intentName)) {
return getHelpResponse();
} else if ("WelcomeChubb".equals(intentName)) {
return getWelcomeResponse();
} else {
throw new SpeechletException("Invalid Intent");
}
}
And I'm trying to handle this as below
private SpeechletResponse getTheFlow(Intent intent, Session session) {
boolean isAskResponse = true;
String responseText = "";
String nameFromSession = (String) session.getAttribute("name");
if (StringUtils.isNullOrEmpty(nameFromSession)) {
responseText = "please give me your name";
getTheNameText(intent, session);
} else {
System.out.println(session.getAttribute("nameFromSession"));
responseText = "please give me your date of birth";
}
return getSpeechletResponse(responseText, "", isAskResponse);
}
private String getTheNameText(Intent intent, Session session) {
String userNameFrmIntent = getNameFromSlot(intent).toString();
session.setAttribute("nameFromSession", userNameFrmIntent);
return getNameFromSlot(intent).toString();
}
private String getNameFromSlot(Intent intent) {
Slot userName = intent.getSlot(Slot_Name);
return userName.getValue();
}
Also, I've defined a slot in the top as below.
private static final String Slot_Name = "custName";
But here when I type Hi, Instead of asking me my name, it is giving me an error in logs it shows Java NullPointer Exception. the response that I get when I type Hi is as below.
{
"session": {
"sessionId": "SessionId.a2740ca4-73ff-4a15-856d-6461b3c7b2e1",

"name": "StartTheFlow",
"slots": {
"custName": {
"name": "custName",
"value": "hi"
}
}
}
},
"version": "1.0"
}
Can someone please let me know where am I going wrong and how can I fix this, I've quite a number of questions to be linked, like 25, can Someone please let me know if there is a better way to do this in java.
Thanks
I would recommend creating a separate intent for each thing that the user says. So for example, HelloIntent, NameIntent, and AgeIntent.
Then be sure to pass those bits of information forward to all following intents in the session. So each intent could use a common function at the beginning to read each string from the session (if exists), add the new slot data to it, and then write all the strings back to the response session before finishing.
Since you'll then have separate intents, and the user could conceivably say them out of order, you may want to check that all the needed strings have been entered, or else prompt the user for any missing strings.
The problem with saving data in the session is that the data will be gone the next time the user starts the skill. To resolve this, you could use a database to hold the users data, saving it keyed to the userId. There are lots of examples on how to do that. Be careful that some databases are essentially free, but others will charge you depending on how many times it is used each month.
