How to catch "No error: PDO constructor was not called" - php

Question

how can I catch the following error: No error: PDO constructor was not called?
My question is not how to solve the error, but how to catch it!
I need that for a PHPUnit Testing Environment.
I was trying to catch it like that, but it simply doesn't work that way.
$pdo = (new \ReflectionClass(\PDO::class))->newInstanceWithoutConstructor();
try
{
$pdo->query("SELECT * FROM table");
}
catch (ErrorException $exc)
{
echo $exc->getTraceAsString();
}
the exact (error) message is as follows: PDO::query(): SQLSTATE[00000]: No error: PDO constructor was not called, but I am not sure, if that is even any type of PHP catchable.
I've already checked the method pdo_raise_impl_error()[PHP 7.3.3] that is called with the mentioned error message, but I am not wise enough to anticipate what actual type of error it produces...
Can please someone give advise?

Answer 1

Not sure if it's a solution you are looking for, but you can always convert all errors to exceptions with as simple code as
set_error_handler(function ($level, $message, $file = '', $line = 0)
{
throw new ErrorException($message, 0, $level, $file, $line);
});
Of course it will make a global error handler, but honestly, I believe every PHP project should have a code like this.
Or at least you can call this handler only temporarily

I now use the following code fore my test.
please check the first and the last line of code especially.
thanks to #YourCommonSense!
set_error_handler(function(int $errno, string $errstr, string $errfile, int $errline) {
throw new ErrorException($errstr, $errno, E_ERROR, $errfile, $errline);
});
$this->expectException(ErrorException::class);
$this->expectExceptionMessage("SQLSTATE[00000]: No error: PDO constructor was not called");
/* #var $pdo PDO */
$pdo = (new ReflectionClass(PDO::class))->newInstanceWithoutConstructor();
$pdo->query("SELECT * FROM table"); // triggers the error.
restore_error_handler();
