@percy/selenium-webdriver
Percy visual testing for Selenium.js.
Installation
$ npm install --save-dev @percy/cli @percy/selenium-webdriver
Usage
This is an example using the percySnapshot
function. For other examples of selenium-webdriver
usage, see the Selenium JS docs.
const { Builder } = require('selenium-webdriver');
const percySnapshot = require('@percy/selenium-webdriver');
(async function example() {
let driver = await new Builder().forBrowser('firefox').build();
try {
await driver.get('http://google.com/');
await percySnapshot(driver, 'Google Homepage');
await driver.get('http://example.com/');
await percySnapshot(driver, 'Example Site');
} finally {
await driver.quit();
}
})();
Running the code above directly will result in the following logs:
$ node script.js

When running with percy exec
, and your project's

, a new Percy build will be created and snapshots will be uploaded to your project.

Upgrading
@percy/migrate
Automatically with We built a tool to help automate migrating to the new CLI toolchain! Migrating can be done by running the following commands and following the prompts:
$ npx @percy/migrate
? Are you currently using @percy/selenium-webdriver (@percy/seleniumjs)? Yes
? Install @percy/cli (required to run percy)? Yes
? Migrate Percy config file? Yes
? Upgrade SDK to @percy/selenium-webdriver@1.0.0? Yes
This will automatically run the changes described below for you.
Manually
@percy/seleniumjs
Uninstalling If you're coming from the @percy/seleniumjs
package, make sure to uninstall that package first
before installing this one.
$ npm uninstall @percy/seleniumjs
Now you can safely install @percy/selenium-webdriver
and @percy/cli
.
@percy/cli
Installing If you're coming from a pre-1.0 version of this package, make sure to install @percy/cli
after
upgrading to retain any existing scripts that reference the Percy CLI command.
$ npm install --save-dev @percy/cli
Migrating Config
If you have a previous Percy configuration file, migrate it to the newest version with the
config:migrate
command:
$ percy config:migrate
