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.
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.

Selenium, a project hosted by the Apache Software Foundation, is an umbrella open-source project comprising a variety of tools and libraries for test automation. Selenium automation framework enables QA engineers to perform automated web application testing using popular programming languages like Python, Java, JavaScript, C#, Ruby, and PHP.
The sky’s the limit (and even beyond that) when you want to run test automation. Technology has developed so much that you can reduce time and stay more productive than you used to 10 years ago. You needn’t put up with the limitations brought to you by Selenium if that’s your go-to automation testing tool. Instead, you can pick from various test automation frameworks and tools to write effective test cases and run them successfully.
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.
Playwright is a framework that I’ve always heard great things about but never had a chance to pick up until earlier this year. And since then, it’s become one of my favorite test automation frameworks to use when building a new automation project. It’s easy to set up, feature-packed, and one of the fastest, most reliable frameworks I’ve worked with.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
