Generating documentation from collections in Postman - Test Execution Trace

Test Overview

This test checks if the Postman collection documentation is generated correctly and is accessible via the documentation URL.

Test Code - Selenium with unittest

Postman

import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

class TestPostmanDocGeneration(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.implicitly_wait(5)

    def test_documentation_accessible(self):
        driver = self.driver
        # Open Postman documentation URL for the collection
        driver.get('https://documenter.getpostman.com/view/1234567/SOME-API-REFERENCE')

        # Wait until the documentation title is visible
        WebDriverWait(driver, 10).until(
            EC.visibility_of_element_located((By.CSS_SELECTOR, 'h1.doc-title'))
        )

        # Verify the documentation title text
        title = driver.find_element(By.CSS_SELECTOR, 'h1.doc-title').text
        self.assertEqual(title, 'Sample API Documentation')

        # Verify that at least one endpoint is listed
        endpoints = driver.find_elements(By.CSS_SELECTOR, '.endpoint')
        self.assertTrue(len(endpoints) > 0)

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Chrome browser window is open and ready	-	PASS
2	Navigates to Postman documentation URL for the collection	Browser loads the documentation page at https://documenter.getpostman.com/view/1234567/SOME-API-REFERENCE	-	PASS
3	Waits until the documentation title element with CSS selector 'h1.doc-title' is visible	Documentation page shows the main title	Checks visibility of the documentation title element	PASS
4	Finds the documentation title element and reads its text	Title element text is 'Sample API Documentation'	Asserts title text equals 'Sample API Documentation'	PASS
5	Finds all elements with CSS selector '.endpoint' representing API endpoints	Multiple endpoint elements are present on the page	Asserts that at least one endpoint element exists	PASS
6	Test ends and browser closes	Browser window is closed	-	PASS

Failure Scenario

Failing Condition: Documentation page does not load or title element is missing

Execution Trace Quiz - 3 Questions

What does the test verify after loading the documentation page?

A The Postman app installation status

B The response time of the API endpoints

C The documentation title text and presence of API endpoints

D The number of tests in the collection

Key Result

Always verify that the documentation page loads correctly and key elements like titles and endpoints are present to ensure generated documentation is accessible and complete.
