Extent Report's HTML File is not generated for LONG running tests

[kmantrala]

We use ADO Pipelines to run our selenium tests written in C#. Our code has references to ExtentReport binaries and for the most part when tests (less than 50) are run on a stand alone machine or using ADO Pipeline running on ADO Agents, we do see that the HTML report is generated at the end.

However off late, our test suites size increased and we roughly run 700 tests per suite/client. These tests takes somewhere between 16 hours to 26 hours to fully run. Due to this, the HTML report after all tests have run are NOT BEING GENERATED. The ADO Pipeline Task we created is to 'Publish Build Artifacts'. This task has the following details:

• Path to Publish: \Results

• Artifact Name: MyResultsName

• Artifact Publish Location: Azure Pipelines

• Control Options:
  Enabled - checked
  Continue on Error - checked

  The XML file configured to generate Extent Reports has the following:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<test-run start-time="2020-12-14 10:28:29Z">
  <command-line><![CDATA[packages\NUnit.ConsoleRunner.3.8.0\tools\nunit3-console.exe  --out=<**Code Location**>\UiResult.txt "--result=<**Code Location**>\UiResult.xml" <**Code Location**>\Testing.dll --where "cat=**TestCategories separated by ||** "]]></command-line>
</test-run>

Can someone let me know what is the reason for the Extent Report's HTML file not getting generated?

Thank you.
