unittesteD

D unittest runner for Codewars.

Example

module solution;

export int add(int a, int b) {
    import std.stdio : stdout;
    stdout.writefln("a = %d, b = %d", a, b);
    return a;
}

module solution_test;

import solution : add;

version(unittest) import fluent.asserts;

@("add returns the sum")
unittest {
    add(1, 1).should.equal(2).because("1 + 1 == 2");
    // assert(add(1, 1) == 2);
}

Run tests with dub test.

The test runner is a heavily modified version of silly, and you should use that instead when testing locally.

Changes from silly

• Changed the output to Codewars format
• Removed multi-threaded mode to easily group outputs from submitted solution under the relevant test
• Removed filtering
• Removed discovery of tests in classes and structs
• Removed fail-fast mode (failure in a test block won't affect others)
• Changed to use std.datetime.stopwatch.StopWatch

Acknowledgements

The test runner is a heavily modified version of silly.
