Research direction

Start by running the supplied parametrized Python test and inspecting the generated pytest-html report. The issue names no repository file or test to begin with, so trace how the testId is inserted into the report. Done means the report consistently renders the testId as literal text rather than interpreting its HTML markup.

Written by the indexing model from the issue text.

Description

Hello,

I created a parametrize test where testId contains the following text:

<span style="font-weight: bold; color: red; font-size: 2em;">text</span>

pytest-html generated the next report:

Is it an expected behaviour?

Test code:

import pytest        
@pytest.mark.parametrize(
    "data",
    [
        '<span style="font-weight: bold; color: red; font-size: 2em;">text</span>',
    ],
)
def test_unescape(data): print("ha-ha")
