1. A method for providing an intervention point for manipulating a quantity of a runtime environment for testing a control unit program component that is to be tested in a test environment having a test scenario program component for providing input quantities and having an observation device for receiving output values and indicating the test result, the method comprising: providing the control unit program component whose interfaces are each defined pursuant to the AUTOSAR standard; creating an executable program of the control unit program component to be tested and of the test scenario program component; generating the runtime environment, wherein the runtime environment provides a communication channel for transmitting the input and output values; and providing a component test service that offers an interface to the runtime environment pursuant to the AUTOSAR standard as an intervention point for manipulating the quantity of the runtime environment and permits access to the quantity of the runtime environment by test scenario program components via suitable code generation for the runtime environment, the quantity determining or describing or influencing a process running over the communication channel.
