Halo teman teman!

Terima kasih untuk WebdriverIO!

Saya mengalami masalah berikut, beri tahu saya apa yang saya lakukan salah 🙏

Lingkungan

Jelaskan bugnya
Silakan periksa log dari Travis CI https://travis-ci.org/halfzebra/wdio-starter/builds/480278039

ERROR webdriver: Request failed due to Error: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

Untuk Mereproduksi
Garpu https://github.com/halfzebra/wdio-starter dan jalankan di Travis CI.

Perilaku yang diharapkan
Harus bekerja di Travis CI
