pytest-html for HTML reports - Test Execution Trace

Test Overview

This test runs a simple function check and generates an HTML report using pytest-html plugin. It verifies that the test passes and the report is created.

Test Code - pytest

PyTest

import pytest

def add(a, b):
    return a + b

def test_add():
    assert add(2, 3) == 5

# To run this test and generate HTML report, use:
# pytest --html=report.html --self-contained-html

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test runner starts pytest with HTML report option	Terminal ready to run pytest command	-	PASS
2	Pytest discovers test_add function	Test function test_add found in test file	-	PASS
3	Pytest executes test_add	Running test_add which calls add(2, 3)	Check if add(2, 3) == 5	PASS
4	Test passes as assertion is true	Test completed successfully	assert 5 == 5	PASS
5	pytest-html plugin generates report.html file	HTML report file created with test results summary	Report file exists and contains test summary	PASS

Failure Scenario

Failing Condition: Assertion in test_add fails (e.g., add(2, 3) != 5)
