Grouping automation tests using Pytest.mark

Pytest allows to group tests using markers. pytest.mark decorator is used to mark a test function with custom metadata like @pytest.mark.smoke

This is very handy when we want to run only a subset of tests like "smoke tests" to quickly verify if the changes made by the developer not breaking any major functionalities.

You can mark a test function with custom metadata like below:

WebDriver tests in PyTest using Fixtures and conftest.py

Fixtures are a powerful feature of PyTest. Fixtures help us to setup some pre-conditions like setup a database connection / get test data from files etc that should run before any tests are executed. Earlier we have seen Fixtures and Scope of fixtures, In this article, will focus more on using fixtures with conftest.py

Using Fixtures in Pytest

You might have heard of the setup method and teardown methods in Unittest [In java, there are similar methods available in TestNG/JUnit]. In pytest, we have fixtures which simplifies the workflow of writing setup and teardown code. Fixtures have explicit names and are activated by declaring them in test functions, modules, classes or whole projects.

Pytest introduction

Locating elements in selenium python

To interact with any web page using selenium, you need to first find webelement/s to perform any action on element.

All the actions you do on a webpage like entering a text into a textbox or textarea and after filling out the form, you may want to click the button to submit data. There are many other operations we do like mousehover, selecting a value from dropdown and navigating between multiple windows/frames which we will discuss more in detail in coming tutorials.

First Example on how to use Selenium with Python

Selenium.webdriver module provides all the WebDriver implementations. WebDriver offers a multiple ways to find element/ find elements using one of the find_element_by_* methods.

Webdriver offers more than one way to locate the elements of your web application in order to find the elements. You can find elements by using ID, name, XPath, CSS Selectors, and more. Know more on Locators for Selenium
