Alex

A Command Line Interface to execute test cases embedded within a python code. Its as simple as 123, just embed the code in the given format and do $ alex <filename>.py

Installation

Using pip:

$ pip install alex-py

From source:

$ python setup.py install

Requirements

• python 2.7.x
• docopt>=1.6.2

Usage

The file should contain test cases in the format:

• The inputs for the file should be in the format

"""I
your input should go here
"""

• The outputs for the file should be in the format

"""O
your expected output should go in here.
"""

The above 2 comments can be anywhere in the file. If you run only with inputs, you will just recieve the output. Also you can have multiple inputs/outputs but length of outputs(if any) should have the same length as inputs, input-output should have same order.

And then execute

$ alex <file-name>

Example

The following is an example file for demonstration: The below file is test.py which is a python solution to this problem on Hackerrank.

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

n = int(raw_input())

for i in range(0,n):
    a, b = raw_input().split()
    a,b = int(a),int(b)
    res = solveMeSecond(a,b)
    print res
    
"""I
2
2 3
3 7
"""

"""O
5
10
"""

Now execute

$ alex test.py
Alex is working on  test.py

YOUR OUTPUT
===========
5
10

EXPECTED OUTPUT
===============
5
10

PASS/FAIL (of 1 testcases)
=========
TESTCASE 1 PASS

You can aslo have multiple testcases like this:

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

n = int(raw_input())

for i in range(0,n):
    a, b = raw_input().split()
    a,b = int(a),int(b)
    res = solveMeSecond(a,b)
    print res

"""I
2
2 3
3 7
"""

"""O
5
10
"""

"""I
3
1 2
3 7
4 5
"""

"""O
3
10
9
"""

If you run:

$ alex test.py

output :

Alex is working on  test.py

YOUR OUTPUT
===========
5
10

3
10
9

EXPECTED OUTPUT
===============
5
10

3
10
9

PASS/FAIL (of 2 testcases)
=========
TESTCASE 1 PASS
TESTCASE 2 PASS
