Simulate a button press with GUILayout

Hello! I’m trying to write some playmode tests, but I’m not sure how to go about simulating a button press when using GUILayout.Button(). Does anyone know how it works?

// Create "Load Project" Button and define onClick action
if (GUILayout.Button("Load Project", GUILayout.Height(40)))
       // Do something when button is pressed

Currently, your code should work.
Is your if(GUILayout.Button("Load Project", GUILayout.Height(40))) {} is inside the void OnGUI() function ?

Try to do the same thing that the code example in the Unity documentation
