This is the slack reporter plugin for TestCafe.

npm install testcafe-reporter-slack

When you run tests from the command line, specify the reporter name by using the --reporter option:

testcafe chrome 'path/to/test/file.js' --reporter slack

When you use API, pass the reporter name to the reporter() method:

testCafe
    .createRunner()
    .src('path/to/test/file.js')
    .browsers('chrome')
    .reporter('slack') // <-
    .run();
