Interacting with UI Form via a test label instead of a label

 jithesh could you please suggest a code how to use testLable if label is not available on click download excel file link? as I am new to Appian-locust.

Hi mohammads3449 

Usually we don't included download link as part of perf test. I am guessing you want to measure the download time for the file.

I don't see any functions provided in "appian for lucust" for this. So I guess you may need to,

1. Get the _documentDownloadLink from json response of your the last ui form interact call.

2. Form the download link url using "/suite/rest/a/content/latest/{opaqueContentId}/o" replace opaqueContentId with _documentDownloadLink

3. Call self.client.get using the above url.

Thanks for update jithesh 

I tried to follow above steps you suggested. But I am get below error:

Error report
# occurrences Error
------------------|-------------------------------------------------------------------------------------------------------------------------------------------1 GET /suite/rest/a/content/latest/_documentDownloadLink/o: HTTPError('500 Server Error: 500 for url: /suite/rest/a/content/latest/_documentDownloadLink/o')
------------------|-------------------------------------------------------------------------------------------------------------------------------------------

On hitting manually below URL :

xxxxx.appiancloud.com/.../o

getting below error on browser:

{"error":"APNX-1-0000-000","message":"An error was encountered while processing your request. "}

Hi, Hope you have replaced with the actual encoded string from last response.

For example this is a section from response json. 

"link": {
    "_documentDownloadLink": "ioB7vr6GjFvUNxPq2Miwv1qGKHukxgjgKuFwb6p5zZv_2wQwAlSDT3Igbo",
    "_cId": "f12c63bb69315fb33e3137d47088dfdd",
    "document": {
      "id": 771239,
      "#t": "CollaborationDocument"
    },
    "label": "",
    "version": -1,
    "metricKey": "",
    "#t": "DocumentDownloadLink"
  }

So the document url will be,

/suite/rest/a/content/latest/ioB7vr6GjFvUNxPq2Miwv1qGKHukxgjgKuFwb6p5zZv_2wQwAlSDT3Igbo/o

Hi, Yes same I did.

Below is the section from response json.

link":{
"_documentDownloadLink":"ioBRM6r2ZR-dSBC6M8A0YS40UJXHFJgjNtYJ5Ng6MK1HKkLRJarnhLJCk",
"_cId":"321f7b1bea2d292db37226961ae7b5f6",
"testLabel":"Download Activity Task Loader",
"document": {
"id":223327,
"#t":"CollaborationDocument"
},
"label":"",
"version":-1,
"metricKey":"",
"#t":"DocumentDownloadLink"}

Also how to correlate above _documentDownlaodLink value in Appian Locust sail Ui Form?

Able to call the download link successfully

"GET /suite/rest/a/content/latest/ioBRBhHZ1P0RUrscUV0M2LUTUPJN2o1Gn3nC7TwumKibZU5Y6k1G4ZL7BQ/o HTTP/11" 200

Locust task looks like this

    @task
    def download_document(self):
        headers = self.interact.setup_sail_headers()
        
        response = self.client.get(
            f"/suite/rest/a/content/latest/{self.opaqueContentId}/o",
            allow_redirects=True,
            name=f"08 - Download Document - {self.task_name}",
            headers=headers
        )

Like I mentioned, save the self.opaqueContentId from previous response (here I have used a custom function)

self.opaqueContentId = find_unique_key(json_response, "_documentDownloadLink")

You will need to traverse the json using standard python and correlate using a label field.

Thank you jithesh  for you support and quick response.

Actually below is my script:

@task
def validateATL(self):
    response = self.client.get('/suite/sites/maestro')
    if response.ok:
        alt_UiForm = self.appian.visitor.visit_site('Maestro', 'home')
        alt_UiForm.click_card_layout_by_index(4)
        alt_UiForm.select_dropdown_item('Saved Searches', 'PT1')
        alt_UiForm.click_button('SEARCH FOR DATA PREVIEW')
        alt_UiForm.click_button('Export tO Excel')


Here I am getting confused how to get the json response from '

Export tO Excel' button of SailUIForm on run time. as I am getting response from first step:

response = self.client.get('/suite/sites/maestro')

In the same way how did I get from

alt_UiForm.click_button('Export tO Excel')

how ever I get the json response from it and save that file in response folder only for debugging purpose

and that too will be memory issue in the long run to save these json files.


Regards,

I tried with below code but not able to get the value of _documentDownloadLink variable:

corrResp = alt_UiForm.click_button('Export tO Excel')
jsonResponse = corrResp.get_latest_state()
print(jsonResponse)
try:
    opaqueContentId = re.search(r"_documentDownloadLink\':\'(.+?)\',", jsonResponse.text)
    self.opaqueContentId = opaqueContentId.group(1)
    print(self.opaqueContentId)
except AttributeError:
    self.opaqueContentId = ""

please suggest is it the right way or not.

Yes thats correct. Either use regex search like you have done here, or parse the json and traverse json nodes.

Maybe try to debug line by line if you are stuck.

Thanks for reply. Here I did it as shown below:

response = alt_UiForm.click_button('Export tO Excel')
corresp = response.get_latest_state()
ddl = str(corresp).split("'link': {'_documentDownloadLink':")[-1]
documentDownloadLink = str(ddl).split(",")[0]
opaqueContentId = re.sub("[' ']","",documentDownloadLink)             
self.client.get(f"/suite/rest/a/content/latest/{opaqueContentId}/o")

But no downloaded file found in download folder.
