Tests number step validation by valid_number_step().

Code

function testNumberStepOffset() {
  // Try obvious fits.
  $this->assertTrue(valid_number_step(11.3, 10.3, 1));
  $this->assertTrue(valid_number_step(100, 10, 50));

  // Ensure a small offset is still invalid.
  $this->assertFalse(valid_number_step(10.3, 10.3, 0.0001));
  $this->assertFalse(valid_number_step(1 / 5, 1 / 7, 1 / 11));

  // Try negative values and offsets.
  $this->assertFalse(valid_number_step(-100, 90 / 7, -10));
  $this->assertFalse(valid_number_step(1000, 10, -5));
  $this->assertFalse(valid_number_step(-10, 4, 0));
  $this->assertFalse(valid_number_step(-10, 4, -4));
