cbPlaywright

CFML integration with TestBox and Playwright to run tests in actual browsers

Dependencies

Testbox v4

ColdBox is not required.

Installation

Add Java Jars to tests/Application.cfc

this.javaSettings = {
	loadPaths: directoryList(
		rootPath &  "modules/cbPlaywright/lib",
		true,
		"array",
		"*jar"
	),
	loadColdFusionClassPath: true,
	reloadOnChange: false
};

Make sure you have a mapping to cbPlaywright as well.

this.mappings[ "/cbPlaywright" ] = rootPath & "/modules/cbPlaywright";

Note: You can't use the mapping in the javaSettings since they are both in the psuedo-constructor.

(OPTIONAL) If you have installed CommandBox or commandbox-cbplaywright in a non-standard location, set the CBPLAYWRIGHT_DRIVER_DIR environment variable to the correct location of the Playwright driver.

Playwright CLI

To interact with the Playwright CLI, use commandbox-cbplaywright:

playwright-cli
# or
playwright

You can see the documentation for the Playwright Java CLI here.

Installing Test browsers

To use Playwright, first you must install one or more test browsers. Refer to the Playwright docs on Browsers for more information.

Examples:

box playwright install chromium
box playwright install firefox
box playwright install webkit
box playwright install msedge

Usage

To use cbPlaywright, create a test spec that extends either cbPlaywright.models.PlaywrightTestCase or cbPlaywright.models.ColdBoxPlaywrightTestCase. What's the difference between these two? PlaywrightTestCase extends testbox.system.BaseSpec while ColdBoxPlaywrightTestCase extends coldbox.system.testing.BaseTestCase. Basically, if you need to access your ColdBox app in your Playwright test, use ColdBoxPlaywrightTestCase.

NOTE: ColdBox is not required to use cbPlaywright. The only dependency is TestBox.

component extends="cbPlaywright.models.PlaywrightTestCase" {
	// ...
}

A PlaywrightTestCase CFC automatically creates a variables.playwright instance in the beforeAll method.

If you have a beforeAll on your test case, make sure to call super.beforeAll(). Otherwise, you will not have access to the variables.playwright instance.

This playwright variable is an instance of the Java Playwright class. From this variable you can create browsers to start running your tests.

component extends="cbPlaywright.models.PlaywrightTestCase" {

	function run() {
		describe( "home page", () => {
			it( "can visit the home page", () => {
				var browser = variables.playwright.firefox().launch();
				var page = browser.newPage();
				navigate( page, "http://" & CGI.HTTP_HOST );
				waitForLoadState( page );
				expect( page.title() ).toBe( "Welcome to my site!" );
			} );
		} );
	}

}

All of the methods above are called on the Java objects provided by the Playwright Java SDK. When using cbPlaywright, you will often reference the Playwright Java SDK documentation.

Helper Functions

cbPlaywright provides helper functions to make interacting with the Java SDK easier.

You can find all of these helper functions inside cbPlaywright.models.PlaywrightMixins

route

Builds up a URL string to the currently running server. It can take any amount of arguments and will intelligently combine them into a path prepended with the current CGI.HTTP_HOST.

Name	Type	Required	Default	Description
paths	string	false	null	This is a variadic parameter. Any number of strings can be passed as separate arguments. They will all be combined into one URL path prepended with the current `CGI.HTTP_HOST`.

Example:

route( "/users", userId, "edit" );
// http://127.0.0.1:51423/users/42/edit

getByRole

https://playwright.dev/docs/locators#locate-by-role https://playwright.dev/java/docs/api/class-page#page-get-by-role

Allows locating elements by their ARIA role, ARIA attributes and accessible name.

Consider the following DOM structure.

<h3>Sign up</h3>
<label>
  <input type="checkbox" /> Subscribe
</label>
<br/>
<button>Submit</button>

You can locate each element by it's implicit role:

expect( getByRole( page, "heading", { name: "Sign up" } ).isVisible() ).toBeTrue();
check( getByRole( page, "checkbox", { name: "Subscribe" } ) );
click( getByRole( page, "button", { name: regex( "submit", "i" ) } ) );

click( cfcastsLink );

getByLabel

https://playwright.dev/docs/locators#locate-by-label https://playwright.dev/java/docs/api/class-page#page-get-by-label

Allows locating input elements by the text of the associated or aria-labelledby element, or by the aria-label attribute.

For example, this method will find inputs by label "Username" and "Password" in the following DOM:

click(
	locateElement(
		page,
		"text=Playwright: Fast and reliable end-to-end testing for modern ..."
	)
);
waitForUrl( page, "https://playwright.dev/" );

Running a Codegen Session

Codgen is a way to interact with a browser and record the actions to copy to your test. You can do this from the Playwright Java CLI.

java -cp "modules/cbPlaywright/lib/*" -Dplaywright.cli.dir="lib/driver/linux/" com.microsoft.playwright.CLI codegen {YOUR_SITE_HERE}

Make sure to copy the code out before closing any windows. You will need to massage some of the generated Java code to fit CFML, specifically anything with arrow functions.
