🤗 [Question]: In fiber v3 - how to test context

[JonasDoe]

Question Description

To get a better understanding of the new fiber.Ctx (and possibly test some custom setters later on), I'm trying to create a test like how setting and getting values work. (See an example in the snippet below.)

However, fiberCtx.SetContext(...) won't achieve anything b/c c.fasthttp == nil. My question is: Is there a more straight-forward way than this?

app := fiber.New()
app.Get("/", func(ctx fiber.Ctx) error {
	ctx.SetContext(context.WithValue(context.Background(), "hello", "world"))
	assert.Equal(t, "world", ctx.Context().Value("hello"))
	...
	return ctx.SendStatus(200)
})
req := httptest.NewRequest("GET", "/", nil)
...

Code Snippet (which won't work due to c.fasthttp == nil)

// Some tests are supposed to fail. But none of them will work b/c setting the value will never work
func TestFiberCompatibility(t *testing.T) {
	fiberCtx := fiber.NewDefaultCtx(fiber.New())
	fiberCtx.SetContext(context.WithValue(context.Background(), "hello", "world"))
	assert.Equal(t, "world", fiberCtx.Context().Value("hello"))
	assert.Equal(t, "world", fiberCtx.Value("hello"))
	assert.Equal(t, "world", fiberCtx.Locals("hello"))
	if fromContext, ok := fiber.ValueFromContext[string](fiberCtx, "hello"); assert.True(t, ok) {
		assert.Equal(t, "world", fromContext)
	}
	if fromContext, ok := fiber.ValueFromContext[string](fiberCtx.Context(), "hello"); assert.True(t, ok) {
		assert.Equal(t, "world", fromContext)
	}

	fiberCtx2 := fiber.NewDefaultCtx(fiber.New())
	fiber.StoreInContext(fiberCtx2, "hello", "world")
	assert.Equal(t, "world", fiberCtx2.Context().Value("hello"))
	assert.Equal(t, "world", fiberCtx2.Value("hello"))
	assert.Equal(t, "world", fiberCtx2.Locals("hello"))
	if fromContext2, ok := fiber.ValueFromContext[string](fiberCtx2, "hello"); assert.True(t, ok) {
		assert.Equal(t, "world", fromContext2)
	}
	if fromContext2, ok := fiber.ValueFromContext[string](fiberCtx2.Context(), "hello"); assert.True(t, ok) {
		assert.Equal(t, "world", fromContext2)
	}
}
