A pytest plugin for colorful print statements

pytest-crayons

A pytest plugin for colorful print statements.

Installation

pip install pytest-crayons

Usage

1. Include a color fixture in the param list of a test.
2. Then use it instead of print.

def test_something(blue):
    ... # some code
    blue("a print statement, that shows up blue")
    ... # more test code

Just like normal print statements, you only see the output if:

• There's an failure in the test.
• or you pass in -s or --capture=no
• or you wrap the statement in a with capsys.disabled(): block.

For our examples, we'll use -s:

Available colors

• red,
• green
• yellow
• blue
• magenta
• cyan

Example with all colors:

def test_colors(red, green, yellow, blue, magenta, cyan):
    print("") # for the newline
    red("this should be in red")
    green("this should be in green")
    yellow("this should be in yellow")
    blue("this should be in blue")
    magenta("this should be in magenta")
    cyan("this should be in cyan")
