Publish your Playwright test results to your favorite Slack channel(s).
- 💌 Send results your Playwright test results to one or more Slack channels
- 📊 Conditionally send results to Slack channels based on test results
- 📄 Include additional meta information into your test summary e.g. Branch, BuildId etc
- 🧑🎨 Define your own custom Slack message layout!
Run following commands:
yarn
yarn add playwright-slack-report -D
npm
npm install playwright-slack-report -D
Modify your playwright.config.ts file to include the following:
reporter: [
[
"./node_modules/playwright-slack-report/dist/src/SlackReporter.js",
{
channels: ["pw-tests", "ci"], // provide one or more Slack channels
sendResults: "always", // "always" , "on-failure", "off"
},
],
["dot"], // other reporters
],Enable incoming webhooks in your Slack workspace by following the steps as per Slack's documentation:
https://api.slack.com/messaging/webhooks
Once you have enabled incoming webhooks, you will need to copy the webhook URL and specify it in the config:
reporter: [
[
"./node_modules/playwright-slack-report/dist/src/SlackReporter.js",
{
slackWebHookUrl: "https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX",
sendResults: "always", // "always" , "on-failure", "off"
},
],
["dot"], // other reporters
],You will most likely need to have Slack administrator rights to perform the steps above.
Sending failure details in a thread is not supported when using webhooks. You will need to use Option B below.
Run your tests by providing your SLACK_BOT_USER_OAUTH_TOKEN as an environment variable or specifying slackOAuthToken option in the config:
SLACK_BOT_USER_OAUTH_TOKEN=[your Slack bot user OAUTH token] npx playwright test
NOTE: The Slack channel that you specify will need to be public, this app will not be able to publish messages to private channels.
🔎 How do I find my Slack bot oauth token?
You will need to have Slack administrator rights to perform the steps below.
- Navigate to https://api.slack.com/apps
- Click the Create New App button and select "From scratch"
- Input a name for your app and select the target workspace, then click on the Create App button
- Under the Features menu, select OAuth & Permissions and scroll down to Scopes section
- Click the Add an OAuth Scope button and select the following scopes:
- chat:write
- chat:write.public
- chat:write.customize
- Scroll up to the OAuth Tokens for Your Workspace and click the Install to Workspace button
You will be prompted with the message below, click the Allow button
The final step will be to copy the generated Bot User OAuth Token aka SLACK_BOT_USER_OAUTH_TOKEN.
Treat this token as a secret.
An example advanced configuration is shown below:
import { generateCustomLayout } from "./my_custom_layout";
import { LogLevel } from '@slack/web-api';
...
reporter: [
[
"./node_modules/playwright-slack-report/dist/src/SlackReporter.js",
{
channels: ["pw-tests", "ci"], // provide one or more Slack channels
sendResults: "always", // "always" , "on-failure", "off"
layout: generateCustomLayout,
maxNumberOfFailuresToShow: 4,
meta: [
{
key: 'BUILD_NUMBER',
value: '323332-2341',
},
{
key: 'WHATEVER_ENV_VARIABLE',
value: process.env.SOME_ENV_VARIABLE, // depending on your CI environment, this can be the branch name, build id, etc
},
{
key: 'HTML Results',
value: '<https://your-build-artifacts.my.company.dev/pw/23887/playwright-report/index.html|📊>',
},
],
slackOAuthToken: 'YOUR_SLACK_OAUTH_TOKEN',
slackLogLevel: LogLevel.DEBUG,
disableUnfurl: true,
showInThread: true,
},
],
],An array of Slack channels to post to, at least one channel is required
Can either be "always", "on-failure" or "off", this configuration is required:
- always - will send the results to Slack at completion of the test run
- on-failure - will send the results to Slack only if a test failures are encountered
- off - turns off the reporter, it will not send the results to Slack
A function that returns a layout object, this configuration is optional. See section below for more details.
- meta - an array of meta data to be sent to Slack, this configuration is optional.
Same as layout above, but asynchronous in that it returns a promise.
Limits the number of failures shown in the Slack message, defaults to 10.
Don't consider flaky tests as passed, instead output them separately. Flaky tests are tests that passed but not on the first try. This defaults to false but it is highly recommended that you switch this on.
Instead of providing an environment variable SLACK_BOT_USER_OAUTH_TOKEN you can specify the token in the config in the slackOAuthToken field.
This option allows you to control slack client severity levels for log entries. It accepts a value from @slack/web-api LogLevel enum:
- ERROR
- WARN
- INFO
- DEBUG
Example: slackLogLevel: "ERROR", will only log errors to the console.
Enable or disable unfurling of links in Slack messages.
Instructs the reporter to show the failure details in a thread instead of the main channel.
String representation of your proxy server. Example:
proxy: "http://proxy.mycompany.com:8080",
The meta data to be sent to Slack. This is useful for providing additional context to your test run.
Examples:
...
meta: [
{
key: 'Suite',
value: 'Nightly full regression',
},
{
key: 'GITHUB_REPOSITORY',
value: 'octocat/telsa-ui',
},
{
key: 'GITHUB_REF',
value: process.env.GITHUB_REF,
},
],
...You can define your own Slack message layout to suit your needs.
Firstly, install the necessary type definitions:
yarn add @slack/types -D
Next, define your layout function. The signature of this function should adhere to example below:
import { Block, KnownBlock } from "@slack/types";
import { SummaryResults } from "playwright-slack-report/dist/src";
const generateCustomLayout = (summaryResults: SummaryResults):Array<KnownBlock | Block> => {
// your implementation goes here
}
export default generateCustomLayout;In your, playwright.config.ts file, add your function into the config.
import { generateCustomLayout } from "./my_custom_layout";
...
reporter: [
[
"./node_modules/playwright-slack-report/dist/src/SlackReporter.js",
{
channels: ["pw-tests", "ci"], // provide one or more Slack channels
sendResults: "always", // "always" , "on-failure", "off"
layout: generateCustomLayout,
...
},
],
],Pro Tip: You can use the block-kit provided by Slack when creating your layout.
Example 1: - very simple summary
import { Block, KnownBlock } from '@slack/types';
import { SummaryResults } from '..';
export default function generateCustomLayoutSimpleExample(
summaryResults: SummaryResults,
): Array<Block | KnownBlock> {
return [
{
type: 'section',
text: {
type: 'mrkdwn',
text:
summaryResults.failed === 0
? ':tada: All tests passed!'
: `😭${summaryResults.failed} failure(s) out of ${summaryResults.tests.length} tests`,
},
},
];
}Generates the following message in Slack:
Example 2: - very simple summary (with Meta information)
Add the meta block in your config:
reporter: [
[
"./node_modules/playwright-slack-report/dist/src/SlackReporter.js",
{
channels: ["demo"],
sendResults: "always", // "always" , "on-failure", "off",
layout: generateCustomLayout,
meta: [
{
key: 'EXAMPLE_META_node_env',
value: process.env.HOME ,
},
],
},
],
],Create the function to generate the layout:
import { Block, KnownBlock } from '@slack/types';
import { SummaryResults } from '..';
export default function generateCustomLayoutSimpleMeta(
summaryResults: SummaryResults,
): Array<Block | KnownBlock> {
const meta: { type: string; text: { type: string; text: string; }; }[] = [];
if (summaryResults.meta) {
for (let i = 0; i < summaryResults.meta.length; i += 1) {
const { key, value } = summaryResults.meta[i];
meta.push({
type: 'section',
text: {
type: 'mrkdwn',
text: `\n*${key}* :\t${value}`,
},
});
}
}
return [
{
type: 'section',
text: {
type: 'mrkdwn',
text:
summaryResults.failed === 0
? ':tada: All tests passed!'
: `😭${summaryResults.failed} failure(s) out of ${summaryResults.tests.length} tests`,
},
},
...meta,
];
}Generates the following message in Slack:
Example 3: - With screenshots and/or recorded videos (using AWS S3)
In your, playwright.config.ts file, add these params (Make sure you use layoutAsync rather than layout):
import { generateCustomLayoutAsync } from "./my_custom_layout";
...
reporter: [
[
"./node_modules/playwright-slack-report/dist/src/SlackReporter.js",
{
...
layoutAsync: generateCustomLayoutAsync,
...
},
],
],
use: {
...
screenshot: "only-on-failure",
video: "retain-on-failure",
...
},Create the function to generate the layout asynchronously in my_custom_layout.ts:
import fs from "fs";
import path from "path";
import { Block, KnownBlock } from "@slack/types";
import { SummaryResults } from "playwright-slack-report/dist/src";
import { PutObjectCommand, S3Client } from "@aws-sdk/client-s3";
const s3Client = new S3Client({
credentials: {
accessKeyId: process.env.S3_ACCESS_KEY || "",
secretAccessKey: process.env.S3_SECRET || "",
},
region: process.env.S3_REGION,
});
async function uploadFile(filePath, fileName) {
try {
const ext = path.extname(filePath);
const name = `${fileName}${ext}`;
await s3Client.send(
new PutObjectCommand({
Bucket: process.env.S3_BUCKET,
Key: name,
Body: fs.createReadStream(filePath),
})
);
return `https://${process.env.S3_BUCKET}.s3.${process.env.S3_REGION}.amazonaws.com/${name}`;
} catch (err) {

if (t.status === "failed" || t.status === "timedOut") {
fails.push({
type: "section",

fails.push({
type: "context",
elements: [{ type: "mrkdwn", text: assets.join("\n") }],
});
}
}
}
return [header, summary, { type: "divider" }, ...fails]
}Example 4: - Upload the attachments to directly to Slack
To enable this functionality, make sure the slackbot user has the following additional scopes:
files:writefiles:read
You will need to re-install the app and re-invite the bot into the channel.
The value of the channel_id should be the channel id of the channel you want to upload the file to. This channel id can be found in the url when you are in the channel. e.g.
https://app.slack.com/client/T02RVEEFPDH/C05H7TKVDUK
^ the bit starting with 'C...' is your channel id. In this case, the channel id is C05H7TKVDUK
...
const web_api_1 = require('@slack/web-api');
const slackClient = new web_api_1.WebClient(process.env.SLACK_BOT_USER_OAUTH_TOKEN);
async function uploadFile(filePath) {
try {
const result = await slackClient.files.uploadV2({
channel_id: 'C05H7TKVDUK', << this is the channel id not channel name! ☠️
file: fs.createReadStream(filePath),
filename: filePath.split('/').at(-1),
});
return result.file;
} catch (error) {
console.log('🔥🔥 error', error);
}
}
export async function generateCustomLayoutAsync (summaryResults: SummaryResults): Promise<Array<KnownBlock | Block>> {
const { tests } = summaryResults;
....
// See the snippet above ^^^
if (t.attachments) {
for (const a of t.attachments) {
const file = await uploadFile(a.path);
if (file) {
if (a.name === 'screenshot' && file.permalink) {
fails.push({
alt_text: '',
image_url: file.permalink,
title: { type: 'plain_text', text: file.name || '' },
type: 'image',
});
}
if (a.name === 'video' && file.permalink) {
fails.push({
alt_text: '',
// NOTE:
// Slack requires thumbnail_url length to be more that 0
// Either set screenshot url as the thumbnail or add a placeholder image url
thumbnail_url: '',
title: { type: 'plain_text', text: file.name || '' },
type: 'video',
video_url: file.permalink,
});
}
}
}
}
....
return [header, summary, { type: "divider" }, ...fails]
