Is it possible to change the duration format from just seconds to something like hh:mm:ss?

[brettnolan]

Is there a way to format the duration time to something like:
HH:MM:SS
or
h hours, m mins, s secs

I tried doing it within here, by changing the attribute value

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
    outcome = yield
    report = outcome.get_result()
    report.description = str(item.function.__doc__)

    # change duration format here
    duration = getattr(report, "duration", 0.0)                          
    converted_duration = timedelta(seconds=duration)
    setattr(report, "duration", converted_duration)

However, plugin.py didn't like the format

INTERNALERROR>   File python-virtual-environments/python3_env/lib/python3.6/site-packages/pytest_html/plugin.py", line 162, in __init__
INTERNALERROR>     html.td(f"{self.time:.2f}", class_="col-duration"),
INTERNALERROR> TypeError: unsupported format string passed to datetime.timedelta.__format__

Hi @brettnolan let me look into this for you

[gnikonorov]

@brettnolan can you paste the output of pip list please?

[gnikonorov]

duration comes from the pytest api and must always be in seconds which is why you are getting the error you are seeing.

However, I think it would make sense for pytest-html to do the formatting on your behalf ( I don't really see a reason why 3721 is clearer than 01:02:01, for example )

I'll have a PR up in a day or two for this

Thanks!

Hey @brettnolan this functionality is now on the master branch and documentation for it can be found here.

Thanks for raising this issue!

[gnikonorov]

Hi @brettnolan you can get this functionality by installing the latest version of pytest-html from PyPI

Formatting the Duration Column
The formatting of the timestamp used in the Durations column can be modified by setting duration_formatter on the report attribute. All time.strftime formatting directives are supported. In addition, it is possible to supply %f to get duration milliseconds. If this value is not set, the values in the Durations column are displayed in %S.%f format where %S is the total number of seconds a test ran for.

Below is an example of a conftest.py file setting duration_formatter:

`import pytest

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
outcome = yield
report = outcome.get_result()
setattr(report, "duration_formatter", "%H:%M:%S.%f")`

NOTE: Milliseconds are always displayed with a precision of 2

For future readers of this: The support for duration formatting has been removed in v4.

If there's enough interest in re-implementing support, we will provide a way for you to, via a hook for example, to provide your own formatting functionality.
