Library: Assertions
Assertions for unit testing contracts. Tests are run with the
<solUnit at https://github.com/smartcontractproduction/sol-unit>
unit-testing framework.
(start code)
contract ModAdder {
function addMod(uint a, uint b, uint modulus) constant returns (uint sum) {
if (modulus == 0)
throw;
return addmod(a, b, modulus);
}
}
contract SomeTest {
using Assertions for uint;
function testAdd() {
var adder = new ModAdder();
adder.addMod(50, 66, 30).equal(26, "addition returned the wrong sum");
}
}
(end)
It is also possible to extend <Test>, to have all bindings (using) properly set up.
(start code)
contract SomeTest is Test {
function testAdd() {
var adder = new ModAdder();
