At 10up, we strive to provide digital products that yield a top-notch user experience. In order to improve both our efficiency and consistency, we need to standardize what we use and how we use it. This theme scaffold allows us to share initial set up procedures to make sure all projects can get up and running as quickly as possible while closely adhering to 10up's high quality standards.
- Node@^8.11.0 & NPM - Build packages and 3rd party dependencies are managed through NPM, so you will need that installed globally.
- Composer - Composer is used to manage PHP.
Install 10up's command line tool for scaffolding new projects. You can download it from the Project Scaffold repository. Setting up a new theme is as easy as running
create-10up theme theme-name-here in the terminal!
Browsersync requires a local development URL. This is currently set in the
- Clone the repository
- Rename folder theme-scaffold -> your project's name
- If copying files manually to an existing theme directory instead of cloning directly from the repository, make sure to include the following files which may be hidden:
.babelrc .browserslistrc .editorconfig .eslintignore .eslintrc .gitignore
The NPM commands will fail without these files present.
Do case-sensitive search/replace for the following:

npm run start
Webpack config files can be found in
In most cases
webpack.settings.js is the main file which would change from project to project. For example adding or removing entry points for JS and CSS.
npm run start(install dependencies)
npm run watch(watch)
npm run build(build all files)
npm run build-release(build all files for release)
npm run dev(build all files for development)
npm run lint-release(install dependencies and run linting)

npm run lint-js(lint JS)
npm run lint-php(lint PHP)

composer lint-fix(lint PHP files and automatically correct coding standard violations)
* If your host machine's local version of PHP is <7.2, composer may produce the following, or similar, error message:
Problem 1 - Installation request for 10up/wpacceptance dev-master -> satisfiable by 10up/wpacceptance[dev-master]. - 10up/wpacceptance dev-master requires php >=7.2 -> your PHP version (7.1.23) does not satisfy that requirement
To suppress this error, add the flag
composer install --ignore-platform-reqs).
Automated Style Guide
The Theme Scaffolding ships with a default style guide you can find in
/templates/page-styleguide.php. This file contains all the basic HTML elements you would find at the very top of the cascade (headings, typography, tables, forms, etc.) These base elements will be styled and displayed as you naturally build out your CSS. The style guide also automatically pulls in the color variables used in the project. Any hex codes added into
/assets/css/frontend/global/variables.css will be automatically displayed in the style guide. To set up your style guide, you just need to create a new page in WordPress and assign it the "Style Guide" template.
If you need to update the core styles that power the style guide they are located in
/assets/css/styleguide and will naturally process with the rest of the CSS.
As your site grows you can add components to the style guide by updating
/templates/page-styleguide.php as you see fit. All the JS and CSS for the site will already be included in the template, so everything should just work.
Automated Accessibility Testing
Automated accessibility testing in the Theme Scaffolding is done with Pa11y and is executed with the command
npm run test-a11y. You can find any configuration options inside your
package.json file inside the
testing object. You will see default URL options (homepage, article, search-results), but you can add as many as you'd like. The default script runs over the
local URL and any others will run with an argument like
npm run test-a11y production, over a production URL. You can also add more template URLs for testing like
npm run a11y-test article-template. Be sure to check with your systems person on a project to make sure accessibility tests are also hooked up through the deploy process.
Compliance levels can also be updated through the
testing.accessibility.compliance object in the
package.json file. The default is WCAG Level A, but it can be updated to anything listed in the pa11y documentation.
The test file lives in
/tests/accessibility/compliance/pa11y.js if any edits are needed (such as staging credentials, if you're running tests in an environment that requires authentication).
Visual Regression Testing
We use BackstopJS to run our visual regression tests. BackstopJS requires just a few settings to work: a
scenarios array that tells it which URL's to screenshot, a
viewports array that tells it what breakpoints to use, and a
config object for global settings.
Begin by setting which URL's you'd like to test in the
testing.urls object in
package.json. You will see some default URL's (homepage, article, search-results), but you can add as many as you'd like. These URL's are read by
tests/visual/scenarios.js to automatically produce the
scenarios array that BackstopJS will use to take screenshots.
You can also create custom scenarios in
tests/visual/custom-scenarios.js. Custom scenarios allow us to add specific options for specific URL's, for situations like hovering over an element to screenshot its hover state, or clicking a modal button and waiting for the modal to become visible.
To create a custom scenario, simply set the
urlName property to match the property name in the
testing.urls object, and then create an
options object with your desired settings. A couple examples are provided in
tests/visual/custom-scenarios.js and you can see a list of all available options in the advanced scenarios section on GitHub.
BackstopJS can take screenshots at various screen widths, so make sure to match the breakpoints in
tests/visual/viewports.js with those in your theme.
Though generally not necessary, you can customize the BackstopJS configuration by changing the settings in
To begin running BackstopJS visual regression tests, initialize its required files. This only needs to be done once on your local machine:
npm run test:visual-init
Then create a set of screenshots that will become the base reference images to run future tests against:
npm run test:visual-reference
After you've made changes and want to test for visual regressions:
npm run test:visual
Finally, if the new screenshots fail but contain desired changes, approve them for use as the new base reference images:
npm run test:visual-approve
Automated Acceptance Testing
Automated acceptance testing in the Theme Scaffolding leverages WP Acceptance and is included in the project via Composer as a dev required package. Run the command
composer update (see Composer Commands above) to install the required packages. Refer to the documentation to ensure your host machine has the necessary requirements. The Theme Scaffolding is already setup to work with WP Acceptance and a few example tests have been created to serve as examples.
To run the test suite, from the root of the repository, run
./vendor/bin/wpacceptance run. WP Acceptance will automatically run the test suite in isolated docker containers. To write your own acceptance tests, refer to the documentation and cookbook.
