Get the DOM element containing the text. DOM elements can contain more than the desired text and still match. Additionally, Cypress prefers some DOM elements over the deepest element found.
Syntax
.contains(content) .contains(content, options) .contains(selector, content) .contains(selector, content, options) // ---or--- cy.contains(content) cy.contains(content, options) cy.contains(selector, content) cy.contains(selector, content, options)
Usage
Correct Usage
cy.get('.nav').contains('About') // Yield el in .nav containing 'About' cy.contains('Hello') // Yield first el in document containing 'Hello'
Incorrect Usage
cy.title().contains('My App') // Errors, 'title' does not yield DOM element cy.getCookies().contains('_key') // Errors, 'getCookies' does not yield DOM element
Arguments
content (String, Number, RegExp)
Get the DOM element containing the content.
selector (String selector)
Specify a selector to filter DOM elements containing the text. Cypress will ignore its default preference order for the specified selector. Using a selector allows you to return more shallow elements (higher in the tree) that contain the specific text.
options (Object)
Pass in an options object to change the default behavior of .contains()
.
Option | Default | Description |
---|---|---|
matchCase | true | Check case sensitivity |
log | true | Displays the command in the Command log |
timeout | defaultCommandTimeout | Time to wait for .contains() to resolve before timing out
|
includeShadowDom | includeShadowDom config option value | Whether to traverse shadow DOM boundaries and include elements within the shadow DOM in the yielded results. |
Yields
.contains()
yields the new DOM element it found.
Examples
Content
Find the first element containing some text
<ul> <li>apples</li> <li>oranges</li> <li>bananas</li> </ul>
// yields <li>apples</li> cy.contains('apples')
Find the input[type='submit']
by value
Get the form element and search in its descendants for the content “submit the form!”
<div id="main"> <form> <div> <label>name</label> <input name="name" /> </div> <div> <label>age</label> <input name="age" /> </div> <input type="submit" value="submit the form!" /> </form> </div>
// yields input[type='submit'] element then clicks it cy.get('form').contains('submit the form!').click()
Number
Find the first element containing a number
Even though the <span>
is the deepest element that contains a “4”, Cypress automatically yields <button>
elements over spans because of its preferred element order.
<button class="btn btn-primary" type="button"> Messages <span class="badge">4</span> </button>
// yields <button> cy.contains(4)
Regular Expression
Find the first element with text matching the regular expression
<ul> <li>apples</li> <li>oranges</li> <li>bananas</li> </ul>
// yields <li>bananas</li> cy.contains(/^b\w+/)
Selector
Specify a selector to return a specific element
Technically the <html>
, <body>
, <ul>
, and first <li>
in the example below all contain “apples”.
Normally Cypress would return the first <li>
since that is the deepest element that contains “apples”.
To override the element that is yielded we can pass ‘ul’ as the selector.
<html> <body> <ul> <li>apples</li> <li>oranges</li> <li>bananas</li> </ul> </body> </html>
// yields <ul>...</ul> cy.contains('ul', 'apples')
Keep the form as the subject
Here’s an example that uses the selector to ensure that the <form>
remains the subject for future chaining.
<form> <div> <label>name</label> <input name="name" /> </div> <button type="submit">Proceed</button> </form>
cy.get('form') // yields <form>...</form> .contains('form', 'Proceed') // yields <form>...</form> .submit() // yields <form>...</form>
Without the explicit selector the subject would change to be the <button>
. Using the explicit selector ensures that chained commands will have the <form>
as the subject.
Case Sensitivity
Here’s an example using the matchCase
option to ignore case sensitivity.
<div>Capital Sentence</div>
cy.get('div').contains('capital sentence') // fail cy.get('div').contains('capital sentence', { matchCase: false }) // pass
Notes
Scopes
.contains()
acts differently whether it’s starting a series of commands or being chained off an existing series.
When starting a series of commands:
This queries the entire document
for the content.
cy.contains('Log In')
When chained to an existing series of commands
This will query inside of the <#checkout-container>
element.
cy.get('#checkout-container').contains('Buy Now')
Be wary of chaining multiple contains
Let’s imagine a scenario where you click a button to delete a user and a dialog appears asking you to confirm this deletion.
// This doesn't work as intended cy.contains('Delete User').click().contains('Yes, Delete!').click()
Because the second .contains()
is chained off of a command that yielded the <button>
, Cypress will look inside of the <button>
for the new content.
In other words, Cypress will look inside of the <button>
containing “Delete User” for the content: “Yes, Delete!”, which is not what we intended.
What you want to do is call cy
again, which automatically creates a new chain scoped to the document
.
cy.contains('Delete User').click() cy.contains('Yes, Delete!').click()
Leading, trailing, duplicate whitespaces aren’t ignored in <pre>
tag
Unlike other tags, <pre>
doesn’t ignore leading, trailing, or duplicate whitespaces as shown below:
<!--Code for test--> <h2>Other tags</h2> <p> Hello, World !</p> <h2>Pre tag</h2> <pre> Hello, World !</pre>
Rendered result:
To reflect this behavior, Cypress also doesn’t ignore them.
// test result for above code cy.get('p').contains('Hello, World !') // pass cy.get('p').contains(' Hello, World !') // fail cy.get('pre').contains('Hello, World !') // fail cy.get('pre').contains(' Hello, World !') // pass
Single Element
Only the first matched element will be returned
<ul id="header"> <li>Welcome, Jane Lane</li> </ul> <div id="main"> <span>These users have 10 connections with Jane Lane</span> <ul> <li>Jamal</li> <li>Patricia</li> </ul> </div>
The below example will return the <li>
in the #header
since that is the first element that contains the text “Jane Lane”.
// yields #header li cy.contains('Jane Lane')
If you wanted to select the <span>
instead, you could narrow the elements yielded before the .contains()
.
// yields <span> cy.get('#main').contains('Jane Lane')
Preferences
Element preference order
.contains()
defaults to preferring elements higher in the tree when they are:
input[type='submit']
button
a
label
Cypress will ignore this element preference order if you pass a selector argument to .contains()
.
Favor of <button>
over other deeper elements
Even though the <span>
is the deepest element that contains “Search”, Cypress yields <button>
elements over spans.
<form> <button> <i class="fa fa-search"></i> <span>Search</span> </button> </form>
// yields <button> cy.contains('Search').children('i').should('have.class', 'fa-search')
Favor of <a>
over other deeper elements
Even though the <span>
is the deepest element that contains “Sign Out”, Cypress yields anchor elements over spans.
<nav> <a href="/users"> <span>Users</span> </a> <a href="/signout"> <span>Sign Out</span> </a> </nav>
// yields <a> cy.get('nav').contains('Sign Out').should('have.attr', 'href', '/signout')
Favor of <label>
over other deeper elements
Even though the <span>
is the deepest element that contains “Age”, Cypress yields <label>
elements over <span>
.
<form> <label> <span>Name:</span> <input name="name" /> </label> <label> <span>Age:</span> <input name="age" /> </label> </form>
// yields label cy.contains('Age').find('input').type('29')
Rules
Requirements
.contains()
can be chained off ofcy
or off a command that yields DOM element(s).
Assertions
.contains()
will automatically retry until the element(s) exist in the DOM..contains()
will automatically retry until assertions you've chained all pass.
Timeouts
.contains()
can time out waiting for the element(s) to exist in the DOM..contains()
can time out waiting for assertions you've added to pass.
Command Log
Element contains text “New User”
cy.get('h1').contains('New User')
The commands above will display in the Command Log as:
When clicking on the contains
command within the command log, the console outputs the following:
