Mocking a build-in PHP function is achieved by using
PHP's namespace fallback policy. A mock will provide the namespaced function.
I.e. only unqualified functions in a non-global namespace can be mocked.
Example:
namespace foo;
use phpmock\Mock;
$time = new Mock(
__NAMESPACE__,
"time",
function () {
return 3;
}
);
$time->enable();
assert (3 == time());
$time->disable();
assert (3 != time());
/**
* Tests redefining mocks in a different namespace.
*
* @test
* @dataprovider provideTestNamespace
*/
public function testRedefiningNamespaces()
{
$this->builder->setNamespace(__NAMESPACE__);
$this->mock = $this->builder->build();
$this->mock->enable();
$this->assertEquals(1234, time());
}
/**
* Tests disabling the mock.
*
* @test
*/
public function testEndTest()
{
$min = new Mock(__NAMESPACE__, "min", "max");
$min->enable();
$this->assertEquals(9, min(1, 9));
$disabler = new MockDisabler($min);
$disabler->endTest($this, 1);
$this->assertEquals(1, min(1, 9));
}

*
* @param string $mockName The mock function name.

{
$builder = new MockBuilder();
$builder->setNamespace(__NAMESPACE__)->setName($mockName)->setFunctionProvider(new FixedValueFunction(1234));
$this->mock = $builder->build();
$this->mock->enable();
$this->assertEquals(1234, time(), "time() is not mocked");
$this->assertEquals(1234, Time(), "Time() is not mocked");
$this->assertEquals(1234, TIME(), "TIME() is not mocked");
