This is Markdown file directive2.md

Directives are HTML comments and are not rendered. To see the directives press Edit on GitHub and then the Raw button.

This will be marked as the setup code.

The setup logic makes the names assigned here global to the test module. The code assigns the names math, mylist, a, b, and the function doubler(). Setup code does not have an output block. Note the  directive in the Markdown file.

import math

mylist = [1, 2, 3]
a, b = 10, 11

def doubler(x):
    return x * 2

This test case shows the setup names are visible.

print("math.pi=", round(math.pi, 3))
print(mylist)
print(a, b)
print("doubler(16)=", doubler(16))

expected output:

math.pi= 3.142
[1, 2, 3]
10 11
doubler(16)= 32

This test case modifies mylist.

The objects created by the –setup code can be modified and blocks run afterward will see the changes.

mylist.append(4)
print(mylist)

expected output:

[1, 2, 3, 4]

This test case sees the modified mylist.

print(mylist == [1, 2, 3, 4])

expected output:

True

This will be marked as the teardown code.

Teardown code does not have an output block. Note  directive in the Markdown file.

mylist.clear()
assert not mylist, "mylist was not emptied"
