Exercise 1h) - Testing the solve function 1p Write two tests where you test that both the time array and the solution to the ODE is correct test_solve_time: Should make sure that: The first time point is zero. The last time point is T. The difference between the second and first time point is dt. test_solve_solution: Should make sure that the relative error of the difference between the exact and computed is within 1%. Both tests should be parametrized using pytest.mark.parametrize with respect to a, up, T and dt and test at least three different inputs. Hint - Comparing with the exact solution The exact solution of the exponential decay ODE is given by u(t)= use Hint - Computing the relative error If you have the compute solution y and the exact solution y_exact then you can compute the relative error as import numpy as np relative_error = np. linalg.norm(y- y_exact) /np.linalg.nor
