Disable a method in a class that is NOT mocked

I have a simple class with a parser

class Parser
{
    public function __construct(P1 $p1, P2 $p2)
    {
        $this->p1 = $p1;
        // etc...
    }

    public function parse()
    {
        $this->doSomething1();
        return $this->doSomething2(P3 $p3);
    }
}

then I have my test class

class ParserTest
{
    public function testParse()
    {

      $p1 = $this->getMockBuilder(P1::class)->disableOriginalConstructor()->getMock();
      $p2 = $this->getMockBuilder(P2::class)->disableOriginalConstructor()->getMock();
      $p3 = $this->getMockBuilder(P3::class)->disableOriginalConstructor()->getMock();
     
      $parser = new Parser ($p1, $p2);
      $result = $parser->parse($p3);

    }
}

what I need to do is disable doSomething1 for the test because it is basically doing an API call, so I can test what is in result. How can I do that?

You could use a PHPUnit partial mock (I didn't find a valid doc for this, only some PR or in the source code) of your class under test, as example:

    $methods = ["doSomething1"];


    $parser = $this->getMockBuilder(Parser::class)
        ->disableOriginalClone()
        ->disableArgumentCloning()
        ->disallowMockingUnknownTypes()
        ->onlyMethods($methods)
        ->setConstructorArgs([$p1, $p2])
        ->getMock();

NB: Because you need to pass data in the constructor you can't use the short-cat version:

    $this->createPartialMock(Parser::class, $methods);

As El_Vanja already suggested, it's best to extract that API call. If you can't do it right now, you can override the doSomething1 method for the test:

class ParserTest
{
    public function testParse()
    {
      $p1 = $this->getMockBuilder(P1::class)->disableOriginalConstructor()->getMock();
      $p2 = $this->getMockBuilder(P2::class)->disableOriginalConstructor()->getMock();
      $p3 = $this->getMockBuilder(P3::class)->disableOriginalConstructor()->getMock();
     
      $parser = new class($p1, $p2) extends Parser {
            protected function doSomething1()
            {
            }
      };

      $result = $parser->parse($p3);
    }
}
