You need to call wait on the promise or manually tick the promise queue.

Hi,
I'm attempting to do some unit testing using a class that utilizes the promises library. Here's the general approach (in a file MyTest.php):
use PHPUnit\Framework\TestCase;
class MyTest extends TestCase {
/**
- Tests unit testing with callbacks.
*/
public function testFoo() {
$p = new FulfilledPromise("");
$me = $this;
$p->then(function() use ($me) {
$me->assertTrue(TRUE, "Foo promise returning method succeeded.");
print (sprintf("%s::%s line %s: Success callback executed\n", get_class($this), FUNCTION, LINE));
}, function() use ($me) {
$me->assertTrue(FALSE, "Foo promise returning method succeeded.");
print (sprintf("%s::%s line %s: Failure callback executed\n", get_class($this), FUNCTION, LINE));
});
}
}
The test completes without any assertions occurring (at least, none whose output is recognized by the testing suite). It appears the callbacks execute after the unit test completes:PHPUnit 5.2.9 by Sebastian Bergmann and contributors.
Runtime: PHP 5.6.18 with Xdebug 2.3.3
Configuration: [excluded]. 1 / 1 (100%)
Time: 154 ms, Memory: 5.25Mb
OK (1 test, 0 assertions)
MyTest::{closure} line 91: Success callback executed
Do you know of a decent approach to using PHPUnit with Guzzle promises?—

Can you tell me where? I tried changing the method to:
/**
* Tests unit testing with callbacks.
*/
public function testFoo() {
$p = new FulfilledPromise("");
$me = $this;
$p->then(function() use ($me) {
$me->assertTrue(TRUE, "Foo promise returning method succeeded.");
print (sprintf("%s::%s line %s: Success callback executed\n", get_class($this), __FUNCTION__, __LINE__));
}, function() use ($me) {
$me->assertTrue(FALSE, "Foo promise returning method succeeded.");
print (sprintf("%s::%s line %s: Failure callback executed\n", get_class($this), __FUNCTION__, __LINE__));
});
$p->wait();
}
but the problem remains. 1 test, 0 assertions

Oh wow. I'm highly overcomplicating this.
/**
* Tests unit testing with callbacks.
*/
public function testFoo() {
$p = new FulfilledPromise(TRUE);
$result = $p->then(function() {
return TRUE;
}, function() {
return FALSE;
})->wait();
$this->assertTrue($result, "Testing foo");
}
Nm. :)

And thank you, by the way. Appreciate the help.
