Window / testing opengl/sfml application
« on: August 30, 2023, 10:26:47 am »
Hi folks,
I created a template project to develop OpenGL applications. I do window management with SFML/Window.
Let's say I created a "Shader" class, and there is function like "loadFromFile" similar to that of SFML and if this function loads shaders correctly it also calls function to compile shaders.
What approach should I take when I want to test the functions of this shader class?
We know that in order for any OpenGL commands to work, a context must be current. SFML's window class does this for us.
Do I need to create context like below for tests with opengl calls? Or how should I set up a structure for more isolated test codes?
