Running Webdriver.IO tests on Cloud testing platforms e.g. Browserstack

BrowserStack : Stop using virtual machines for browser testing

Sick of booting up an entire virtual machine (VM) just to test something in IE? With BrowserStack, you don’t need VMware or VirtualBox. Just enter a URL and instantly test on just about any browser you can think of.

A BrowserStack engineer explains:

SoapUI with BDD (Cucumber)

Background Web Service is a way to publish your application over internet and enable other applications to access functions provided by it. With web service, one could reuse the existing applications, instead of developing the same application over and over again.

Leveraging Modules in Geb

Geb Page and Module classes are just regular Groovy classes. In addition to the contentDSL you can declare methods just as you would in any other class. Those methods can use content properties directly.

Page object methods tend to fall into two categories:

Ubuntu – Password protect GRUB menu

We can achieve this by editing the configuration

gksu gedit /etc/grub.d/00_header /etc/grub.d/30_os-prober

Add this at the bottom of 00_header:

cat << EOF set superusers="user1" password user1 password1 EOF

That way the edits will be password protected, with that user and password.

Now, let’s protect the Windows entry. Open 30_os-prober and find this line:
