StageCrewMember

You can think of the StageCrewMember as an in-memory microservice that reacts to domain events, published by the StageManager, and originally emitted by actors performing activities and Serenity/JS test runner adapters notifying the framework about test scenario-specific events like SceneStarts or SceneFinishes.

Every StageCrewMember receives a reference to the Stage, and therefore StageManager as well, which enables them to emit DomainEvents back.

This interface is useful when you’re interested in implementing custom Serenity/JS reporters or supporting services.

Implementing a custom StageCrewMember

import { Stage, StageCrewMember } from '@serenity-js/core'
import * as events from '@serenity-js/core/lib/events'
import { ArbitraryTag } from '@serenity-js/core/lib/model'

export class TestRunnerTagger implements StageCrewMember {

  static using(tagName: string) {
    return new TestRunnerTagger(tagName);
  }

  protected constructor(
    private readonly tagName: string,
    private stage?: Stage,
  ) {
  }

  assignedTo(stage: Stage): StageCrewMember {
    this.stage = stage;
    return this;
  }

  notifyOf(event: events.DomainEvent): void {
    if (event instanceof events.TestRunnerDetected) {
      this.stage.announce(
        new events.SceneTagged(
          this.stage.currentSceneId(),
          new ArbitraryTag(this.tagName),
          this.stage.currentTime()
        )
      )
    }
  }
}

Using the custom StageCrewMember

import { configure } from '@serenity-js/core'

configure({
  crew: [
    TestRunnerTagger.using(`Node:${ process.version }`),
  ]
})
