[Question] How to act as logged user in tests?

Describe your question I’m using sessionAttribute and AccessManager for authentication / authorization. I do like writing acceptance tests on REST API level. Question: Is there any common pattern to act as a logged user in tests?

Currently, I added an optional endpoint (added only in tests) like:

if (testMode) {
    app.post("/test-login", ctx -> {
        ctx.sessionAttribute(PRINCIPAL_SESSION_KEY, ctx.bodyAsClass(Principal.class));
    });
}

// ..
public record Principal(UUID userId, String username, Set<Role> roles) implements Serializable {
}

and then in tests I’m using this endpoint before tested endpoint, but that’s quite verbose (?)

Another way is to perform a check against an environment variable, or check for localhost, inside the AccessManager:

config.accessManager { ...
    if (evn == local) ctx.sessionAttribute(PRINCIPAL_SESSION_KEY, ctx.bodyAsClass(Principal.class));
    // normal access manager code
}

A tutorial would be cool !
