Crazy little PHP idea I was toying with this morning...

crazy.php

<?php

class Expectation
{
  function __construct($value) {
    $this->value = $value;
  }

  function toBe($expected) {
    return $this->value === $expected;
  }
}

function describe($msg, $block) {
  echo "{$msg}\n";
  $block();
}

function it($msg, $block) {
  echo "{$msg}\n";
  $result = $block();
}

function expect($value) {
  return new Expectation($value);
}


/* An example of a test */
describe("A test", function() {
  it("has expectations", function() {
    expect(true)->toBe(true);
  });
});

describe("Another test", function() {
  describe("wrapped in another test", function() {
    it("has even more expectations", function() {
      expect(42)->toBe(42);
    });
  });
});
