Project description

A python tool to distributively run GCJ/FB hacker cup testcases on several machines.

First the splitter runs on the input file to split it into seprate test cases.
Test cases with the actuall code are sent to the server.
The server distributes the test cases and the actuall code to its registered nodes.
Each node computes the result for its testcases and sends the result back to the server
The server collects the results and sort them by their testcase number and sends them back to the calling script.

pip install dTests

Create new project:
```
dtests_job new project_name language
```
The only supported languages now are “cpp” and “java”.
Open the new folder and code your splitter to read from the input.in file.
Between each test cases print “–split–\n”. The split marker can be configured in “config.json” file. This will split the input file into single test cases which will be distributed on the machines running.
Code your program file to read from stdin as if it is reading a single test cases.
Run the server
```
dtests_server
```
Run one or many nodes on other machines ( or for testing on the same machine ):
```
dtests_node --host host --port port
```
Finally run the job:
```
dtests_job run
```
Check the help of these commands for further customizations

This is a sample cpp project that takes input and multiply it by itself https://github.com/MohamedBassem/dTests/tree/master/samples/power2

The config.json file contains the project configuration. The language and the splitter syntax.
The splitter.cpp file contains the code that reads the input from the “input.in” file and splits it to single test cases.
The program.cpp file that reads a single test cases from stdin and computes the result.
To Run this project, run the server and at least one node. Then run “dtests_job run” in the project’s directory.
