A modern testing framework

Viper

A modern testing framework.

Basic Tests

Viper was made for people of all types and expertise. To make a simple test, you can use the following code:

from viper import Viper

snake = Viper("Example Tests")

def addition(a, b):
    return a + b

snake.test("check if addition function can solve 5 + 5", addition(5, 5), 10)

snake.evaluate()

On running this, you should get:

Running tests for "Example Tests"
Testing "check if addition function can solve 5 + 5"... Passed

Ran 1 test(s) in 0.0004 seconds
1/1 passed

And if we change the 10 to become something else like so:

snake.test("check if addition function can solve 5 + 5", addition(5, 5), 7)

The output becomes:

Running tests for "Example Tests"
Testing "check if addition function can solve 5 + 5"... Failed
   Desired Output: "7" | Test Ouput: "10"

Ran 1 test(s) in 0.0006 seconds
0/1 passed

As one can see, the testing outputs are made so that it is simple, yet it is also informative

API Testing

Viper can also be used as an API test:

from viper import Viper
import requests

snake = Viper("Example Tests")

def checkCompletion():
    return requests.get("https://jsonplaceholder.typicode.com/todos/1").json()["completed"]

snake.test("check if todo is completed or not", checkCompletion(), False)

snake.evaluate()

The output of that is:

Running tests for "Example Tests"
Testing "check if todo is completed or not"... Passed

Ran 1 test(s) in 0.0009 seconds
1/1 passed

Importing and Exporting Tests

With Viper, you can import and export tests, something that is hard to do with other frameworks. For example, say you have two files, a.py and b.py. a.py:

from viper import Viper

snake = Viper("Example Tests")

def addition(a, b):
    return a + b

snake.test("check if addition function can solve 5 + 5", addition(5, 5), 10)

def export():
    return snake.tests

b.py:

from a import export
from viper import Viper

snake = Viper("Importing data")

snake.importFromFile(export())

snake.evaluate()

Running, b.py gives us the output of:

Running tests for "Importing data"
Testing "check if addition function can solve 5 + 5"... Passed

Ran 1 test(s) in 0.0002 seconds
1/1 passed

As one can see, the importing and exporting works.
