def check_3 ():
	raise Exception ("not 110%")

checks = {

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

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