I have a class like the following:

export class TestClient {
    @InjectValue("VALUE_A")
    private valueA: string;

    public constructor(accessToken: string) {
        const object = {
            host: this.valueA
        };
    }
}

How can I mock, inject, pass a value to valueA from the Jest test file?

it("Should instantiate the client", () => {
    const client = new TestClient("");
    expect(client).toBeInstanceOf(TestClient);
});
