I have a function that utilises therand() function and I would like to unit test it... But I'm struggling.
I am currently using Phockito to help with mocking and mock returns etc
public function myFunction()
{
return hash(
'sha256',
'this is some random string: ' . rand()
);
}
Test file:
public testFunction()
{
$myClass = new MyClass();
$result = $myClass->myFunction();
$expected = /* Some hashed string I expect */;
$this->assertEquals($expected, $result);
}
I have thought about trying to Phockito::mock the class I'm working with, but all of the other functions that are connected in this process will be required to be mocked also... And that will be a lot of work.
Either use a library like php-mock to mock php functions or refactor your function to accept your random as an argument like:
public function myFunction($rand = null) {
$rand = $rand ?? rand();
// ...
}
