Configuration

At the top of the wdio.conf.js-file, add:

ES6

// wdio.conf.js
import SlackReporter from '@moroo/wdio-slack-reporter';

In order to use the reporter you need to add slack to your reporters array in wdio.conf.js

// wdio.conf.js
export.config = {
  reporters: [
    [
      SlackReporter,
      {
        slackOptions: {
          type: 'web-api',
          channel: process.env.SLACK_CHANNEL || 'Cxxxxxxxxxx',
          slackBotToken: process.env.SLACK_BOT_TOKEN || 'xoxb-xxxxxxxxxx-xxxxxx...',
        },
      }
    ],
  ],
};

          }
          return payload;
        }
      }
    ],
  ],
};

Supported API

getResultsUrl

type: () => string | undefined

Get the results url.

// getResultsUrl.spec.ts
import SlackReporter from '@moroo/wdio-slack-reporter';

describe('Get the resultsUrl value', function () {
  before(function () {
    const resultsUrl = SlackReporter.getResultsUrl();
    if (resultsUrl) {

    }
  });
  it('Do something', function () {
    // do something...
  });
});

setResultsUrl

type: (url: string) => void

Set the results url.
(This is useful if the url with test results changes every time.)

// setResultsUrl.spec.ts
import SlackReporter from '@moroo/wdio-slack-reporter';
import { RESULTS_URL } from '../constants';

describe('Set the resultsUrl value', function () {
  before(function () {
    const resultsUrl = RESULTS_URL + new Date().toISOString();
    SlackReporter.setResultsUrl(resultsUrl);
  });
  it('Do something', function () {
    // do something...
  });
});

uploadFailedTestScreenshot

type: (data: string | Buffer) => void

Add a screenshot as a thread to the failed test notification.
(If you are using a webhook this will print a warning and do nothing.)

// terminal console
WARN @moroo/slack-wdio-reporter: Not using web-api or disabled notifyFailedCase or uploadScreenshotOfFailedCase options.

// wdio.conf.js
export.config = {
  afterTest: async function (test, context, result) {
    if (error) {
      const result = await browser.takeScreenshot();
      SlackReporter.uploadFailedTestScreenshot(result);
    }
  }
}

postMessage

type: (payload: ChatPostMessageArguments) => Promise<WebAPICallResult>

Post a message to Slack.
(If you are using a webhook this will throw an error.)

// post.spec.ts
import SlackReporter, {
  ChatPostMessageArguments,
  WebAPICallResult,
} from '@moroo/wdio-slack-reporter';

describe('Post Function Test', function () {
  it('Post a message', async function () {
    const payload: ChatPostMessageArguments = {
      // do something...
    };
    const result: WebAPICallResult = await SlackReporter.post(payload);
  });
});

upload

type: (payload: FilesUploadArguments) => Promise<WebAPICallResult>

Upload a file to Slack.
(If you are using a webhook this will throw an error.)

// terminal console
ERROR @moroo/slack-wdio-reporter: Not using web-api.

// upload.spec.ts
import SlackReporter, {
  FilesUploadArguments,
  WebAPICallResult,
} from '@moroo/wdio-slack-reporter';

describe('Upload Function Test', function () {
  it('Upload a files', async function () {
    const payload: FilesUploadArguments = {
      // do something...
    };
    const result: WebAPICallResult = await SlackReporter.upload(payload);
  });
});

send

type: (payload: IncomingWebhookSendArguments) => Promise<IncomingWebhookResult>

Send a message to Slack.
(If you are using a web-api this will throw an error.)

// terminal console

// send.spec.ts
import SlackReporter, {
  IncomingWebhookSendArguments,
  IncomingWebhookResult,
} from '@moroo/wdio-slack-reporter';

describe('Sand Function Test', function () {
  it('Send a message', async function () {
    const payload: IncomingWebhookSendArguments = {
      // do something...
    };
    const result: IncomingWebhookResult = await SlackReporter.send(payload);
  });
});

Add Screenshot

If you want to add a screenshot as a thread to the failed test notification, added the uploadFailedTestScreenshot function after taking the screenshot.

// wdio.conf.js
export.config = {
  afterTest: async function (test, context, result) {
    if (error) {
      const result = await browser.takeScreenshot();
      SlackReporter.uploadFailedTestScreenshot(result);
    }
  }
}

Known Issues

Unsynced

If the following error occurs, set reporterSyncInterval, reporterSyncTimeout in wdio.conf.js.

ERROR @wdio/runner: Error: Some reporters are still unsynced: SlackReporter

//wdio.conf.js
export.config = {
  //
  // Determines in which interval the reporter should check if they are synchronized if they report their logs asynchronously (e.g. if logs are streamed to a 3rd party vendor).
  reporterSyncInterval: 500,
  // Determines the maximum time reporters have to finish uploading all their logs until an error is being thrown by the testrunner.
  reporterSyncTimeout: 20000,
}

Jasmine Option - expectationResultHandler

Adding the uploadFailedTestScreenshot function here doesn't work either.
This is because the function works after every test, so the current test is unknown.

// wdio.conf.js
export.config = {
  jasmineOpts: {
    // Jasmine default timeout
    defaultTimeoutInterval: 60000,
    //
    // The Jasmine framework allows interception of each assertion in order to log the state of the application
    // or website depending on the result. For example, it is pretty handy to take a screenshot every time
    // an assertion fails.
    expectationResultHandler: function (passed, assertion) {
      if (passed) {
        return;
      }
      /*
        Adding the uploadFailedTestScreenshot function here doesn't work either.
        This is because the function works after every test, so the current test is unknown.

        [x] const result = await browser.takeScreenshot();
        [x] SlackReporter.uploadFailedTestScreenshot(result);
      */
    },
  },

  // Add it here.
  afterTest: async function (test, context, result) {
    if (result.error) {
      const result = await browser.takeScreenshot();
      SlackReporter.uploadFailedTestScreenshot(result);
    }
  }
}
