pytractor

Angular.js for the testing goat: Utilities for testing Angular.js applications with Selenium for Python.

This project has been abandoned!

Unfortunately, due to lack of time and a switch to robotframework-extendedselenium2library this project has been abandoned. Please contact me if you want to take over.

Overview

pytractor is an extension to the Selenium bindings for Python. Its goal is to make testing of angular.js applications easier with Python.

It is built on some parts of protractor, the "official" Javascript E2E/Scenario testing framework for Angular.js.

Usage

It is assumed that you are familiar with with the Selenium bindings for Python.

Basics

Drivers containing the helper methods for testing Angular.js can be found in the pytractor.webdriver module.

The constructor expects the base URL of your application.

from pytractor.webdriver import Firefox

driver = Firefox('http://localhost:8080/base_url')

The base URL will be prepended to each URL you pass to the get() method (using urlparse.urljoin(base_url, get_url)).

The constructor also accepts the parameters:

root_element

A selector for the DOM element that is the root of your Angular.js app (default: 'body').

script_timeout

The amount of seconds (default: 10) to wait for a script executing asynchroneously (see selenium's set_script_timeout().

test_timeout

The amount of seconds (default: 10) to wait for the script which verifies whether Angular.js is indeed used on the page.

If no Angular.js app can be found, get() will raise an exception.

The usual selenium webdriver methods can be used, but pytractor will wait for Angular.js to finish processing for some of them.

Additional methods

Finding Elements

Finding elements by binding

The find_element(s)_by_binding() methods retrieve the element(s) which use the specified binding.

Suppose your Angular app contains a binding of the form

<div>{{my_binding}}</div>

Then you can locate the <div /> with

driver.find_element_by_binding('my_binding')

find_element(s)_by_binding() will also find elements if only part of the binding name is specified. In other words, the binding

<div>{{my_binding}}</div>

can be found with

driver.find_element_by_binding('my_bind')

If you want to locate the binding by its exact name, use find_element(s)_by_exact_binding().

Finding elements by model

find_element(s)_by_model('model_name') can be used to locate elements that use the expression ng-model="model_name".

Suppose you have the element

<input type="text" ng-model="person.name">

then the <input> element can be found with

driver.find_element_by_model('person.name')

Finding elements by repeater

find_element(s)_by_repeater('item in list') can be used to locate elements that use the expression ng-repeat="item in list".

Other Methods and Properties

Refreshing a page

refresh() will perform a full reload of the current page. It assumes that the page uses Angular.js.

Using in-page navigation

set_location(url) will use the in-page navigation (just as $location.url()).

Retrieving the absolute URL

The location_abs_url property will retrieve the absolute URL from angular.

Missing Features

• Button text, and options locators.
• Script/mock module injection.
