React Testing Library - can't find anchor element by role - reactjs

I have the following code:
<div className="button">
<a href={SOME_URL}>
...
...
</a>
</div>
And in my test, if i try to do:
const link = screen.getByRole('link');
I'm getting the following error:
TestingLibraryElementError: Unable to find an accessible element with the role "link"
Running screen.debug(), i'm getting the following:
<div
class="button"
>
<a>
So how come it can't find it?

The a[href] has a default role of link...

You'll need to add an href to the <a>.

How to check if the span element by name has a tag with class higlight using cypress and react?

i am new to programming and learning cypress with react and typescript. i have html like below,
<li>
<a class="StyledListItemContent-sc-wfozlt-l jqmJwr highlight hover link">
//should check if this <a> tag has class "highlight"
<div class="Box-sc fzjcGf"></div>
<div class="Box-sc Flex-sc-1pzo701-0">
<span>some type (some type) </span> //using this span name some type
<span style="display">...</span>
</div>
</a>
</li>
how can i check if the span element with name "some type" has <a> tag with class "highlight" using cypress.
could someone help me with this. thanks.
The span might be accessed with cy.contains() since you are looking for some text in it.
The <a> is a parent but it's two levels above, so cy.parents('a') should find it.
Then the attribute can be asserted.
cy.contains('span', 'some type')
.parents('a')
.should('have.class', 'highlight')

How to click link in Cypress?

I want to click on below link in a page with several other links like this one.
I have tried cy.get() with a number of alternative ways. I also tried cy.contains('Content 6') but received an error.
<div class="column">
<a href="/admin/contents/109">
<div class="ui segment">
<div class="ui center aligned header">
Content 6
<div class="sub header">Add description to content packages
</div>
</div>
</div>
</a>
</div>
This was my final solution:
cy.get('a[href*="admin/contents"]').contains('Content 6').click()
I found the solution on this page and with help from user called Udo: https://docs.cypress.io/faq/questions/using-cypress-faq.html#How-do-I-get-an-element’s-text-contents
The href code gives more example on how to handle this problem then other examples for same problem.
you have to "get" the correct element to click on. in your case it could be handled like this:
// find the link with href attribute containing "admin/contents" and click it
cy.get('a[href*="admin/contents"]').click()

React site warning: The href attribute requires a valid address. Provide a valid, navigable address as the href value jsx-a11y/anchor-is-valid

I am getting a warning on a React site I built
./src/components/layout/Navbar.js [1] Line 31: The href attribute requires a valid
address. Provide a valid, navigable address as the href value jsx-a11y/anchor-is-valid
on the following code:
<p>
{isEmpty(profile.website) ? null : (
<a
className="text-white p-2"
href={profile.website}
target="#"
>
<i className="fas fa-globe fa-2x" />
</a>
)}
{isEmpty(profile.social && profile.social.twitter) ? null : (
<a
className="text-white p-2"
href={profile.social.twitter}
target="#"
>
<i className="fab fa-twitter fa-2x" />
</a>
)}
{isEmpty(profile.social && profile.social.facebook) ? null : (
<a
className="text-white p-2"
href={profile.social.facebook}
target="#"
>
<i className="fab fa-facebook fa-2x" />
</a>
)}
</p>
Even though the warning appears only for the first link, the same warning occurs on the next link if I remove the first link temporarily or change the href of the first link to a static URL.
The links need to appear as just an icon.
I have tried things such as using a button (did not have the correct look), using a function to open the dynamic url, and trying to force the href to be a string by using '' + {profile.website}. Many other suggestions have not worked.
Is there a way to prevent the error, without changing the jsx-a11y rules? Is what I have done not a good pattern, or is it just a bug in React or JSX?
Use href="/#" to replace href="#" OR href="javascript:;" OR href="javascript:void(0);"
It should remove the warnings.
These worked for me to get rid off the warning;
...
<a href={() => false}>...</a>
I've used href="!#" to remove warnings.
This is just a warning not a error that href attribute requires a valid value as # points to nowhere you can add links to href attributes to remove this warnings or if you are still in early development phase just write
/* eslint-disable jsx-a11y/anchor-is-valid */
On top of your code it will remove the warnings from the terminal, the above line disables the rule for the specified file where it is written
/* eslint-disable jsx-a11y/anchor-is-valid */
import React from 'react';
const Header = () =>{
return(
<nav className="navbar navbar-expand-lg navbar-light bg-light">
<a className="navbar-brand" href="#">Navbar</a>
<button className="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span className="navbar-toggler-icon"></span>
</button>
</nav>
)
}
To also prevent default I use this:
<a href="/#" onClick={(e) => e.preventDefault()}>Link Text</a>
Insert space after # so no more warning about it
replace href="#" to href="# "
but better if use like that href="#something" => href="#profile"
please use <button> instead of <a> when there's no href attribute.
official reference
If you really have to use the a tag, it maybe help you:
<a href="#" onClick={ev => {ev.preventDefault(); onClick();}}>"Hello A Tag"</a>
try replacing
target="#"
to
target="_blank"
I got the similar warning for href, I did as follows. May be try this. I got rid of the warning and functionality is intact. I am not sure this is correct. But tried this.
let hrefLink = '#'; passed as a arg like href={hrefLink}
If you are trying to render a page link dynamically then you can switch out an <a> tag for a <div> tag instead. The warning message will go away.
// DON't DO THiS
<a className="page-link" href="javascript:void(0);" onClick={() => onPageChange(page)}>
{page}
</a>;
// TRY THIS INSTEAD
<div className="page-link" onClick={() => onPageChange(page)}>
{page}
</div>;
If you put "javascript" word in the href attribute then you will get a RED WARNING:
index.js:1375 Warning: A future version of React will block
javascript: URLs as a security precaution. Use event handlers instead
if you can.
Reference: EsLint error resolution page
I've used the href in tag a. it's remove warnings.
<a href>Pictures</a>
You also can hide this warning adding a eslint-disable-next-line comment:
// eslint-disable-next-line
<a
onClick={e => {
// do something
}}
>
example
</a>
I've used the following to remove warnings.
<a href="/">
If we have written correct url but it also gives the same error like I put www.reactjs.org then it also gives the same warning. To resolve these problem we have an attribute in anchor tag i.e.
<a
className="App-link"
href="https://reactjs.org"
target="_blank"
rel="noopener noreferrer"
>
Learn React
</a>
className used for style.
href used for links.
target used for open a link into new tab or not.
Rel is used to outcome from that warning in react.
I don't see something wrong if I'm refering to this.
https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/master/docs/rules/anchor-is-valid.md
Check in these links. Some people had the same problem than you and it comes from a Link component. They fix it in adding an exception to .eslintrc:
first link => https://github.com/evcohen/eslint-plugin-jsx-a11y/issues/340
and the second link => How can I fix jsx-a11y/anchor-is-valid when using the Link component in React?
Let me know if it's helping.
Late to the game but surprised no one recommended window.location, which simply sets the same exact route as the current?
Other solutions such as "#", "/#", and "/" actually modify the current route right? For a more generic solution just use window.location to stay on the current page without modification.
<a href="window.location" onClick={...}> Better Solution </a>
If you really want your anchor tag to have an onClick method you must use a valid href link orelse it will throw an error , The href attribute requires a valid value to be accessible. If you cannot provide a valid href, but still need the element to resemble a link, use a button and change it with appropriate styles.
Change you button style with this property to make transparent
button{
background-color: Transparent;
background-repeat:no-repeat;
border: none;
cursor:pointer;
overflow: hidden;
outline:none;
}
and set the text inside the button to the resemble link color
I have use this color
.editcolor{
color: #1890ff;
}
I resolved my errors with this method.
I tried but most of the answers above did not work for me since the newer eslint does not allow most of them. Instead, it mentions disabling eslint for the specific line.
Simply add: // eslint-disable-next-line to the line which comes just before the jsx line that throws error.
Also, add this comment within {/* ... */} else it will show error.
Usage: {/* // eslint-disable-next-line */ }}
They advise the same thing:
Hope this solves it!
You just need to change "#" to "# ". Good luck
<li className="nav-item pointer">
<a onClick={logout} href="/#" className="nav-link">
LOGOUT
</a>
</li>
or just use
href="/"
Do Not Use: <a href='#'>Something</a> but instead use: <a href='/'>Something</a>

driver.find_element_by_css_selector get error

I am able to click the get more link using above code
get more
but how to click on followers link?
<div class="my_show__info">
<a class="my_show__link j_get_follow" href="javascript:;" data-follow="followers"> 90</a>
<a class="my_show__link j_get_follow" href="javascript:;" data-follow="following"> 33</a>
</div>
you can form a xpath and click on the link as mentioned below. if you want using CSS. convert the following xpath with css.
driver.findElement(By.Xpath("//div[#class='my_show__info']/a[#data-follow="followers"])).click()
I am not good with CSS but I guess following should work.
driver.find_element_by_css_selector('div[class='my_show__info']>a[data-follow='followers']').click()
