After some vacations and some priority changes I am back trying to test my gradle plugins.. I got this working

@Test
    fun myTest() {
        val project = ProjectBuilder.builder().build() as ProjectInternal
        project.plugins.apply("MyAndroidPluginId")
        project.evaluate()
        val android = project.extensions.getByName("android") as ApplicationExtension
        assertEquals(android.compileSdk, 33)
    }

Now suppose I change

compileSdk

based in some compilation flag that I pass to gradle, something like

./gradlew someTask -PsdkVersion=34

, how could I test that in my unittest ?
