Prevent Mockery running method if failure

Really unsure if this is possible but better to ask. I am wanting to test that a file is wrtten to the filesystem and using mockery to determine whether this the case. if the test fails, the file is physically written to the disk but if it passes, it isn't. I understand why this is but wondered if there was a way to tell Mockery "If this fails, don't perform the action". My code:

$mock = $this->partialMock(\Illuminate\Filesystem\Filesystem::class, function(\Mockery\MockInterface $mock) {
        $mock->shouldReceive('put')
            ->once()
            ->with('myfile.php', 'the content');
};

I was hoping the inclusion of once may tell mockery "okay, well we're only expecting this one time, so it either passes or fails - we are not expecting a different call to put.

The example above is simple but the application I am working on is a bit more complex and it becomes tiresome having to go and remove the erroneous file if the test fails.
