The two modules to be introduced today are assert and VM. Next we will introduce them separately.
Use assert for testing
Node, we can use the assert module to test the code. Equal () and notequal () are used to determine equality and inequality respectively. The first parameter is the expected value, the second parameter is the real value, and the third parameter is the exception information. The example is as follows:
var assert = require('assert')

In the past, after installing an operating system virtual machine in VMware, it was necessary to install the VMware Tools Enhancement tool in the virtual machine to enable file sharing between host and virtual machines, virtual machine display resolution adaptive tuning, virtual machine display capability enhancement and 3D acceleration.

I haven't used the vmwarevm for a long time. Today I want to install an XP instance for testing. It's too slow to install it with virtualpc. If I don't wait for a long time, I will install it with Vmware, which is much faster than virtualpc.
After the installation is complete, it is important to enable the host operating system to automatically start the specified virtual machine for running. The keyword is a command l
