You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: no_focused_tests.rs
    path of file: ./repos/biome/crates/biome_js_analyze/src/analyzers/nursery
    
    the code of the file until where you have to start completion: use crate::JsRuleAction;
use biome_analyze::{
    context::RuleContext, declare_rule, Ast, FixKind, Rule, RuleDiagnostic, RuleSource,
    RuleSourceKind,
};
use biome_console::markup;
use biome_diagnostics::Applicability;
use biome_js_factory::make;
use biome_js_syntax::{JsCallExpre
    
    fn diagnostic(_: &RuleContext<Self>, range: &Self::State) -> Option<RuleDiagnostic> {
        Some(
            RuleDiagnostic::new(
                rule_category!(),
                range,
                markup! {
                    "Don't focus the test."
                },
            )
            .note("The 'only' method is often used for debugging or during implementation. It should be removed before deploying to production.")
            .note("Consider removing 'only' to ensure all tests are executed.")
        )
    }
