Azure pipelines: How to add failed selenium Xunit test case attachment in VS test task - selenium

Question

I use the Xunit2 selenium framework for automated test cases. Some case fails in pipeline. I want to see the attachment of the fail test case in the Test tab. How can I do this using VS test task?

Answer 1

The option publishRunAttachments: true, it will update attachments to Test run attachment tab, check the pic below
After the VS test task runs, we can get the run ID through the variable VSTEST_TESTRUNID.
Then we could call the RESST API Create Test Result Attachment to add attachments to the test result attachment tab.
Request API:
POST https://dev.azure.com/{organization}/{project}/_apis/test/Runs/{runId}/attachments?api-version=6.0-preview.1

Update1
We could add task power shell and call the rest api via below script:
$connectionToken="{PAT}"
$base64AuthInfo= [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$URL = "https://dev.azure.com/{organization}/{project}/_apis/test/Runs/{runId}/attachments?api-version=6.0-preview.1"

Update2
Check the pic below and notice the URL
According to the screenshot you shared before, it seems that you want to add attachments to the test run instead of test result. So we just need test run ID and we could get the test run ID from variable after the task vs test ends.
If you want to add attachments to test result, we could list all test result via test run ID.
Sample URL:
GET https://dev.azure.com/{organization}/{project}/_apis/test/Runs/{RunID}/results
The add attachments to the test result via test result ID and test run ID.
Sample power shell script to list all test result ID
$connectionToken="{PAT}"
$base64AuthInfo= [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$URL = "https://dev.azure.com/{organization}/{project}/_apis/test/Runs/{RunID}/results"
$Result = Invoke-RestMethod -Uri $URL -Headers #{authorization = "Basic $base64AuthInfo"} -Method Get
foreach($Run in $Result.value){
Write-Host "This test run contain" $Run.id "and the test reuslt name is" $Run.testCase.name
}
Update3
$connectionToken="{PAT}"
$base64AuthInfo= [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$URL = "https://dev.azure.com/{organization}/{project}/_apis/test/Runs/134/results"
$Result = Invoke-RestMethod -Uri $URL -Headers #{authorization = "Basic $base64AuthInfo"} -Method Get
#List all test result get the test result ID via result
foreach($Run in $Result.value){
#Get the test result ID via result
If($Run.outcome -eq "Failed"){
$TestResultID = $Run.id
#Write-Host $TestResultID
#Add attachment via test run ID and test result ID
$TestResultAttachmentURL = "https://dev.azure.com/{organization}/{project}/_apis/test/Runs/{runId}/Results/$($TestResultID)/attachments?api-version=6.0-preview.1"
