-with generic types, you can use same type with different values
-
-```rust
-use test_context::{test_context, TestContext};
-use std::marker::PhantomData;
-
-struct MyGenericContext<T> {
-    value: u32,
-    _marker: PhantomData<T>,
-}
-
-impl TestContext for MyGenericContext<String> {
-    fn setup() -> MyGenericContext<String> {
-        MyGenericContext { value: 1, _marker: PhantomData }
-    }
-}

-fn test_generic_type(ctx: &mut MyGenericContext<String>) {

 Alternatively, you can use `async` functions in your test context by using the
 `AsyncTestContext`.
