LuluTest

LuluTest is an open source browser automation framework using Python and Selenium. It is relatively lightweight in that it mostly provides wrappers for 3rd party library methods that make browser automation and testing more intuitive. The ultimate goal of LuluTest is to get people writing robust automated browser scripts quickly by abstracting out the inherent complexities and peculiarities

Basic Usage

LuluTest is designed to support both white and black box testing. The functions provided will work as long as the machine running the scripts can access the pages under test.

The basic work flow for creating a test is as such:

1. Create a Page object with the URL of the page to be tested.
2. Create an Action object which will interact with elements
3. Create an Element object for each element on the page that will be tested
4. go to the page to be tested
5. Create a Steps object of actions to take on a page
6. Do the Steps
7. Do your assertions

Example Usage

Below is an example test case:

import unittest

from LuluTest.lulu_exceptions import PageNotLoadedError
from LuluTest.page import Page
from LuluTest.element import PageElement
from LuluTest.action import Action
from step import Step, Do, DoStep, Steps


class ExampleTest(unittest.TestCase):
    def test_write_and_click(self):
        page = Page('http://erikwhiting.com/newsOutlet')
        actions = Action()
        page.elements = [
            PageElement(("id", "sourceNews"), "input box"),
            PageElement(("id", "transmitter"), "button"),
            PageElement(("id", "en1"), "english div")
        ]
        actions.go(page)
        actions.input_text(page.get_element("input box"), "Hello")
        actions.click(page.get_element("button"))
        english_div = page.get_element("english div")
        english_text = actions.check_element_text(english_div, "Hello")
        self.assertTrue(english_text)
        actions.close()

Alternatively, you can also build pages via either YAML or JSON and import them for use. For example, the above page can be modeled in newso_outlet.yml like such:

page:
  url: http://erikwhiting.com/newsOutlet
  elements:
    input_box:
      id: sourceNews
    button:
      id: transmitter
    english_div:
      id: en1

import this file into your test script to avoid writing element finding code:

# In a setup method:
base_path = os.getcwd()
prebuilt_pages_directory = base_path + '/fixtures/pages/'
page_configs = [
    prebuilt_pages_directory + 'news_outlet.yml',
    prebuilt_pages_directory + 'other_page.yml',
    prebuilt_pages_directory + 'even_another_page.json',
]
pages = page_factory.generate_pages(page_configs)

# Now all subsequent tests have access to this page object
def test_basic_usage(self):
    page = self.pages['news_outlet']
    actions = Action()
    actions.go(page)
    actions.input_text(page.get_element("input_box"), "Hello")
    actions.click(page.get_element("button"))
    english_div = page.get_element("english_div")
    english_text = actions.check_element_text(english_div, "Hello")
    self.assertTrue(english_text)
    actions.close()

Features

There are two main design philosophies driving the development of LuluTest:

1. Hide the tedium and peculiarities inherent in browser automation from the test scripts themselves, allowing testers to write efficient and robust tests faster

2. Simplify the test writing process as much as possible so non-technical users can contribute basic test cases while freeing technical users to focus on more technically complex issues.

These philosophies are implemented mostly by keeping the sometimes slow response time of web elements in mind. The project aims to avoid explicit waits and sleeps as much as possible.

LuluTest Architecture

Between December of 2019 and January of 2020, the LuluTest architecture was redesigned with better principles and implemented in a way as described in the picture below. If contributing, please do your best to adhere to the intended arhcitecture.

Future Work

The ultimate goal of LuluTest is to power a domain specific language to help facilitate communication between business and technical stakeholders about requirements and testing.
