Overriding Configuration in Tests with Effect Typescript

I am writing tests and I have a test layer:

const TestLayer = ServiceThatIamTesting.DefaultWithoutDependencies.pipe(...)

const TestLayer = ServiceThatIamTesting.DefaultWithoutDependencies.pipe(...)

One of the dependencies is

Configuration

Configuration

layer. I provide some test configuration and write my tests with:

it.layer(TestLayer)((it) => {
    it.effect(...)

it.layer(TestLayer)((it) => {
    it.effect(...)

Now I have a scenario where I want to override one of the configuration values in one of the tests, how do I do it?
I tried these options but none of them work:

// inside test body
const serviceThatIamTesting = yield* ServiceThatIamTesting.pipe(Effect.provide(Layer.succeed(Configuration, Configuration.of(...))))

// inside test body
const serviceThatIamTesting = yield* ServiceThatIamTesting.pipe(Effect.provide(Layer.succeed(Configuration, Configuration.of(...))))

or:

it.effect(() => Effect.gen(...).pipe(Effect.provide(Layer.succeed(Configuration, Configuration.of(...)))))

it.effect(() => Effect.gen(...).pipe(Effect.provide(Layer.succeed(Configuration, Configuration.of(...)))))
