Create virtual machines in a couple of lines

You can specify attributes such as disk size, number of CPU cores, and many more. Testo will create the virtual machine when running the first test mentioning this machine and will constantly watch for its state relevance.

test my_first_test {
  my_vm {
    start
    mouse click "Install Ubuntu"
    wait "Welcome"
    press Enter
    ...
  }
}

Write down your test scripts with simple actions

A test script consists of your expectations (what you expect to see on the virtual machine screen) and your reactions (what you want to do when the screen event has happened). You could use a wide arsenal of actions: from keyboard control to copying files inside the guest system.

test base_test {
  ...
}

test derived_test: base_test {
  ...
}

Build your tests into a hierarchy

Create complex tests based on simple ones. When running a child test, Testo automatically brings the virtual test bench into the state it needs to be in order to run the derived test.
