There is several good practices for creating locators/selectors. Using playwright there is official documentation for each common and unique selector on how-to and what-is doing.
More information in https://playwright.dev/docs/selectors#text-selector
About your case, i would suggest always to use an parent selector for locating an element. When there is a button, try to find its unique parent.
- By id
- By unique class
- Something else unique.
Example:
<dv id=test>
<button id=continue-test>Continue</button>
</div>
In this case you can use the unique id of the button and not the text.
Selector css: #continue-test
But if you, don't have an unique identifier for the button you can use the parent and go down to the button.
Selector css: #test > button
Matching text using css is not possible, but with XPATH can look like this:
//button[text()="Continue"]
This selector MATCHES the text using "equals".
Using playwright:
button:has-text("Continue")
Using has-text and quotes - matches the text using equals.
If you are using another selector for example text=Continue, this will match all elements that CONTAINS the text "Continue"
All this is explained with example in the official documentation for playwright selectors. That does not mean to not use XPATH to achieve the goals.
CSS selectors are fast but kind of restricted to work with text.
Xpath is quite slower but much more powerful to work in text/parent/child elements etc.
I would suggest always to use an parent element with unique identifier and go down to reach your actual element, which will receive the interaction.

With the rapidly evolving technology due to its ever-increasing demand in today’s world, Digital Security has become a major concern for the Software Industry. There are various ways through which Digital Security can be achieved, Captcha being one of them.Captcha is easy for humans to solve but hard for “bots” and other malicious software to figure out. However, Captcha has always been tricky for the testers to automate, as many of them don’t know how to handle captcha in Selenium or using any other test automation framework.
Ruby is a programming language which is well suitable for web automation. Ruby makes an excellent choice because of its clean syntax, focus on built-in library integrations, and an active community. Another benefit of Ruby is that it also allows other programming languages like Java, Python, etc. to be used in order to automate applications written in any other frameworks. Therefore you can use Selenium Ruby to automate any sort of application in your system and test the results in any type of testing environment

Websites and web apps are growing in number day by day, and so are the expectations of people for a pleasant web experience. Even though the World Wide Web (WWW) was invented only in 1989 (32 years back), this technology has revolutionized the world we know back then. The best part is that it has made life easier for us. You no longer have to stand in long queues to pay your bills. You can get that done within a few minutes by visiting their website, web app, or mobile app.
To decide what automation technology to use, we brought together Joe Colantonio, Founder of TestGuild, Sneha. V, Director of Quality Engineering, Everfi, and Carlos Kidman, Director of Engineering, Stealth Startup. The panel discussion was hosted by Mudit Singh, Marketing head at LambdaTest. Mudit decided to take a step backwards and let the panel discussion happen.
