A convenient tool for creating and testing competitive programming solutions (i.e. single file stdin-stdout apps). Automatic compilation and testing via yaml files.

Olymptester

A convinient tool for creating and testing competitive programming solutions (i.e. single file stdin-stdout apps).

Usage:

0. Prerequisite: pipx

python3 -m pip install --user pipx
python3 -m pipx ensurepath

1. Install olymptester package:

python3 -m pipx install git+https://github.com/jrojer/olymptester.git

After installation, to upgrade to the version in this repo's master, do

python3 -m pipx reinstall olymptester

2. Create an app (in C++, Java or Python). See examples.
3. Define tests. See examples.
4. Run the tester to test your solution. python3 -m olymptester path/to/program path/to/tests.yml.

Example:

In the example, a program that inputs integer x from stdin and outputs 2*x to stdout is being tested by olymptester.

In the examples there is

• app.cpp file containing the program
• tests file app.yml, containing stdin and stdout values of 2 test cases

Program:

#include<iostream>

using namespace std;

int main() {
    int x;
    cin >> x;
    cout << 2*x;
    return 0;
}

app.yml

Test 1 simple:
  input: |+
    1
  output: |+
    2

Test 2:
  input: |+
    33
  output: |+
    66 

Running:

$ python3 -m olymptester ./examples/App.java ./examples/app.yml
Test 1 simple        OK         0.150 sec
Test 2               OK         0.139 sec

Another example:

Yaml supports multiline strings.

knapsack.yml:

Test 1:
  input: |+
    1
    4 5
    1 8
    2 4
    3 0
    2 5
    2 3
  output: |+
    13
