As per the discussion in 3092, this commit removes the `fakefunctions.php` file and adds explicit requirements for the `PHPMailerTest::testGivenIdnAddress_addAddress_returns_true()` test method.
Closes 3092
As things were, the `DKIMTest::testDKIMSignOpenSSLNotAvailable()` could not pass as the `DKIMTest` class sets the `USE_EXCEPTIONS` class constant to `true`, which means the method would fail on an exception.
As this test is specifically about testing the behaviour when exceptions are _disabled_, the test needs to be in its own test class, which sets `USE_EXCEPTIONS` to `false`.
That should allow the test to run properly and to pass.
As things were, the `DKIMTest::testDKIMSignOpenSSLNotAvailableException()` test _could_ potentially pass even when another `Exception` than the `PHPMailer\PHPMailer\Exception` was being thrown, as _all_ exceptions extend the PHP native `Exception` class.
Now this risk is not that high, as there is also a check on the exception message, but still.
Making the exception expectation more specific (by changing the import `use` statement), should still make the test more stable.
runfakepopserver.sh expects fakepopserver.sh to be in the working
directory, therefore the tests in PopBeforeSmtpTest have to chdir()
to the test directory first.
The line in fakepopserver.sh echoing Bye needed -en arguments for
echo to process character escapes.
The disconnect() method throws a TypeError when the TCP
connection cannot be created. Error and trace:
