This repository is forked from testla-screenplay-playwright-js to extend it. This package uses the Testla screenplay core package to implement the screenplay pattern for Playwright. By the way, GIKYOKU means "screenplay" in Japanese.
'screenplay'
.toJapanese() // 戯曲
.toAlphabet() // GIKYOKUThis package comes with abilities, question and actions to browse user interfaces and querying APIs.
Tasks group actions into logical entities. Here is a task that uses the actions Navigate, Fill and Click from the web capabilities and Get from api capabilities.
// file: ./task/Login.ts
import { Actor, Task } from 'gikyoku';
import { Click, Fill, Navigate } from 'gikyoku/web';
import { Get} from 'gikyoku/api';
export class Login extends Task {
public async performAs(actor: Actor): Promise<void> {
return actor.attemptsTo(
Navigate.to('https://www.my-fancy-url.com'),
Fill.with(page.locator('#username'), actor.states('username') || ''),
Fill.with(page.locator('#password'), actor.states('password') || ''),
Click.on(page.locator()'#login-button')),
Get.from('https://www.my-fancy-url.com')
);
}
public static toApp(): Login {
return new Login();
}
}Initialize an actor with abilities as Playwright Fixture for later use in a test case.
import { Actor } from "gikyoku";
import { test as base } from "@playwright/test";
type MyActors = {
actor: Actor;
};
const test = base.extend<MyActors>({
actor: async ({ page, request }, use) => {
const actor = Actor.named("TestActor")
.with('username', 'John Doe')
.with('password', 'MySecretPassword');
.can(BrowseTheWeb.using(page))
.can(UseAPI.using(request))
.with("page", page);
await use(actor);
},
});The final step is to define a test case using the Task defined above.
import { Element } from 'gikyoku/web';
import { Login } from './task/Login';
// Example test case with Playwright
test.describe('My Test', () => {
test('My first test', async ({ actor }) => {
// Execute the task Login - as defined further above
await actor.attemptsTo(Login.toApp());
// Check if the login was successful - use the status question from the web package
await actor.asks(
Element.of(
page.locator('#logged-in-indicator')
).visible()
);
});
});Besides the existing actions, abilities and questions it is of course possible to define your own ones. How this is done, please refer to core package.
Since tasks, actions and questions return promises, we advise to make use of the require-await rule in case of using eslint. This will help to prevent unexpected behavior when forgetting to await tasks/actions or questions.
This feature is currently in experimental stage and might see bigger changes.
Testla comes with logging which helps you to debug your test code. When logging is enabled all activities an actor triggers are logged in a comprehensive way to stdout. To enable logging set the DEBUG environment variable as follows:
DEBUG=testla:spTo understand how to enable logging in custom Actions and Questions please refer to the logging guide of Testla Screenplay Core.
See API Specification.
