The structure

📁 performance
	📜 status_1.py

The checks

# status_1.py

def check_1 ():
	print ("check 1")
	
def check_2 ():
	print ("check 2")
	
def check_3 ():
	raise Exception ("not 110%")

checks = {
	"check 1": check_1,
	"check 2": check_2,
	"check 3": check_3
}

The procedure

From the performance directory,

[xonsh] volts status

The report

This is the report that is (hopefully) written to the terminal.

Notes

• Checks are started simultaneously, unless --simultaneous no

  • [xonsh] volts status --simultaneous no

• The fractory glob pattern is "**/status_*.py", but can be changed with --glob-string

  • [xonsh] volts status --glob-string "**/performance_*.py"

Advanced Tutorial

It's recommended to run volts in a .py script.

An example of this can be found in the "_book/advanced tutorial"
section of the documentation.
