...and have the code for the tests just like before.

## Testing: extended example

Now let's extend this example and add more details to see how to test different parts.

### Extended **FastAPI** app file

Let's continue with the same file structure as before:

// Admit updates the toleration of a pod based on the resources requested by it.
// If an extended resource of name "example.com/device" is requested, it adds
// a toleration with key "example.com/device", operator "Exists" and effect "NoSchedule".
// The rationale for this is described in:

// SYNOPSIS:

// double x, y, sin();
// y = sin( x );
//
// DESCRIPTION:
//
// Range reduction is into intervals of pi/4.  The reduction error is nearly
// eliminated by contriving an extended precision modular arithmetic.
//
// Two polynomial approximating functions are employed.
// Between 0 and pi/4 the sine is approximated by
//      x  +  x**3 P(x**2).
// Between pi/4 and pi/2 the cosine is represented as
