babel-plugin-jsx-remove-data-test-id

Remove data-test-id attributes from your production builds.

It's not usually a good idea to couple our test code with DOM element id's or CSS classnames.

Finding by an .o-some-class or #some-id selector couples our test to the CSS; making changes can be expensive from a maintainance point of view, whether they are coming from the CSS or the tests
Finding elements by DOM tag, such as <span /> or <p> can be equally as difficult to maintain; these things move around so if your looking for .first() you might get a nasty surprise

We wanted to decouple our tests from these concerns, in a way that would support both unit level tests and end to end test. Bring in:

data-test-id="some-test-id"

This package give you the ability to strip these test id's from production code.

npm install babel-plugin-jsx-remove-data-test-id --save-dev

Add this to you babel config plugins

plugins: [
    'babel-plugin-jsx-remove-data-test-id'
]

Add data-test-id to your react components

return (
    <div>
        <p data-test-id="component-text">{someText}</p>
    </div>
);

Make sure the plugins are part of your babel config, and build away - that's it. data-test-id's will be stripped.
