Displayed `Total` suite duration is significantly higher than `Sum` suite duration

[imaxymiv]

The report has Total and Sum indicators that represent suite duration. Sum represent the proper value, but Total shows extra time. I checked the setup and tear down sections. They didn't take long compared to what is displayed in Total. Please, check the screenshot.

To Reproduce

1. Go to 'Suites' section
2. Click on 'Toggle groups info'
3. Check the duration of the suite

Expected behavior Total should represent Sum + time for setup and tear down.

Additional context For some reason, there are 8+ hours added to the duration.

Total is the time between start of the very first test and end of the very last one Sum is the sum of all tests durations Max is the max of all tests durations

@baev could you clarify if Sum includes retries?

[baev]

only results that visible in group. Usually retries are hidden, so the answer is not

[imaxymiv]

So such a huge difference can be because of retries, setups, and tear-downs only. Correct me if I'm wrong.

Nope:

Feature 1
  T1
  T2
Feature 2
  T3
  T4

if you run tests in single thread and the order is the following T1 -> T3 -> T2 -> T4 and there is no gaps between tests and durations are the following: T1 - 1m , T2 - 5m , T3 - 1h , T4 - 1s then the following summary will be shown for groups:

Name	Total	Sum	Max
Feature 1	1h 6m	6m	5m
Feature 2	1h 5m 1s	1h 1s	1h

and the timeline

A -------- B --------- C -------- D -------- E
      1m         1h          5m          1s
 
A - start of T1
B - end of T1 and start of T3
C - end of T3 and start of T2
D - end  of T2 and start of T4
E - end of T4

Total for Feature 1 is time between start of T1 and end of T2

start of T1 = X end of T2 = X + AB + BC + CD = X + 1m + 1h + 5m total = X + 1m + 1h + 5m - X = 1h 6m

Thanks for the answer. In case we have multiple everything running in parallel, will Total be equal Sum?

@baev could you clarify?

[imaxymiv]

@baev any updates on this?

nope, see https://github.com/allure-framework/allure2/issues/1704#issuecomment-1192601120
