play_selenium

pytest-play plugin driving browsers using Selenium/Splinter under the hood. Selenium grid compatible and implicit auto wait actions for more robust scenarios with less pain.

More info and examples on:

• pytest-play, documentation
• cookiecutter-qa, see pytest-play in action with a working example if you want to start hacking

Browser based commands

Browser based commands here. play_selenium supports by default browser interactions. For example it can be used for running selenium splinter scenarios driving your browser for your UI test or system tests.

play_selenium is also your friend when page object approach (considered best practice) is not possible. For example:

• limited time, and/or
• lack of programming skills

Instead if you are interested in a page object pattern have a look at pypom_form or pypom.

play_selenium supports automatic waiting that should help to keep your tests more reliable with implicit waits before moving on. By default it waits for node availability and visibility but it supports also some wait commands and wait until a given Javascript expression is ok. So it is at the same time user friendly and flexible.

Conditional commands (Javascript)

Based on a browser level expression (Javascript):

- type: clickElement
  provider: selenium
  locator:
    type: css
    value: body
  condition: "'$foo' === 'bar'"

Supported locators

Supported selector types:

• css
• xpath
• tag
• name
• text
• id
• value

Open a page

With parametrization:

- type: get
  provider: selenium
  url: "$base_url"

or with a regular url:

- type: get
  provider: selenium
  url: https://google.com

Pause

This command invokes a javascript expression that will pause the execution flow of your commands:

- type: pause
  provider: selenium
  waitTime: 1500

If you need a pause/sleep for non UI tests you can use the sleep command provided by the play_python plugin.

Click an element

- type: clickElement
  provider: selenium
  locator:
    type: css
    value: body

Fill in a text

- type: setElementText
  provider: selenium
  locator:
    type: css
    value: input.title
  text: text value

Interact with select input elements

Select by label:

- type: select
  provider: selenium
  locator:
    type: css
    value: select.city
  text: Turin

or select by value:

- type: select
  provider: selenium
  locator:
    type: css
    value: select.city
  value: '1'

Eval a Javascript expression

- type: eval
  provider: selenium
  script: alert('Hello world!')

Create a variable starting from a Javascript expression

The value of the Javascript expression will be stored in play.variables under the name count:

- type: storeEval
  provider: selenium
  variable: count
  script: document.getElementById('count')[0].textContent

Assert if a Javascript expression matches

If the result of the expression does not match an AssertionError will be raised and the test will fail:

- type: verifyEval
  provider: selenium
  value: '3'
  script: document.getElementById('count')[0].textContent

Verify that the text of one element contains a string

If the element text does not contain the provided text an AssertionError will be raised and the test will fail:

- type: verifyText
  provider: selenium
  locator:
    type: css
    value: ".my-item"
  text: a text

Send keys to an element

All selenium.webdriver.common.keys.Keys are supported:

- type: sendKeysToElement
  provider: selenium
  locator:
    type: css
    value: ".confirm"
  text: ENTER

Supported keys:

KEYS = [
    'ADD', 'ALT', 'ARROW_DOWN', 'ARROW_LEFT', 'ARROW_RIGHT',
    'ARROW_UP', 'BACKSPACE', 'BACK_SPACE', 'CANCEL', 'CLEAR',
    'COMMAND', 'CONTROL', 'DECIMAL', 'DELETE', 'DIVIDE',
    'DOWN', 'END', 'ENTER', 'EQUALS', 'ESCAPE', 'F1', 'F10',
    'F11', 'F12', 'F2', 'F3', 'F4', 'F5', 'F6', 'F7', 'F8',
    'F9', 'HELP', 'HOME', 'INSERT', 'LEFT', 'LEFT_ALT',
    'LEFT_CONTROL', 'LEFT_SHIFT', 'META', 'MULTIPLY',
    'NULL', 'NUMPAD0', 'NUMPAD1', 'NUMPAD2', 'NUMPAD3',
    'NUMPAD4', 'NUMPAD5', 'NUMPAD6', 'NUMPAD7', 'NUMPAD8',
    'NUMPAD9', 'PAGE_DOWN', 'PAGE_UP', 'PAUSE', 'RETURN',
    'RIGHT', 'SEMICOLON', 'SEPARATOR', 'SHIFT', 'SPACE',
    'SUBTRACT', 'TAB', 'UP',
]

Wait until a Javascript expression matches

Wait until the given expression matches or raise a selenium.common.exceptions.TimeoutException if takes too time.

At this time of writing there is a global timeout (20s) but in future releases you will be able to override it on command basis:

- type: waitUntilCondition
  provider: selenium
  script: document.body.getAttribute('class') === 'ready'

Wait for element present in DOM

Present:

- type: waitForElementPresent
  provider: selenium
  locator:
    type: css
    value: body

or not present:

- type: waitForElementPresent
  provider: selenium
  locator:
    type: css
    value: body
  negated: true

Wait for element visible

Visible:

- type: waitForElementVisible
  provider: selenium
  locator:
    type: css
    value: body

or not visible:

- type: waitForElementVisible
  provider: selenium
  locator:
    type: css
    value: body
  negated: true

Assert element is present in DOM

An AssertionError will be raised if assertion fails.

Present:

- type: assertElementPresent
  provider: selenium
  locator:
    type: css
    value: div.elem

or not present:

- type: assertElementPresent
  provider: selenium
  locator:
    type: css
    value: div.elem
  negated: true

Assert element is visible

An AssertionError will be raised if assertion fails.

Present:

- type: assertElementVisible
  provider: selenium
  locator:
    type: css
    value: div.elem

or not present:

- type: assertElementVisible
