I tried this code:

// test the behavior of the --no-run flag //@ check-pass //@ compile-flags:-Z unstable-options --test --no-run --edition 2024 --test-args=--test-threads=1 //@ normalize-stdout: "tests/rustdoc-ui/doctest" -> "$$DIR" //@ normalize-stdout: "finished in \d+\.\d+s" -> "finished in $$TIME" /// ``` /// let a = true; /// ``` /// ```should_panic /// panic!() /// ``` /// ```ignore (incomplete-code) /// fn foo() { /// ``` /// ```no_run /// loop { /// println!("Hello, world"); /// } /// ``` /// fails to compile /// ```compile_fail /// let x = 5; /// x += 2; // shouldn't compile! /// ``` /// Ok the test does not run /// ``` /// panic!() /// ``` /// Ok the test does not run /// ```should_panic /// loop { /// println!("Hello, world"); /// panic!() /// } /// ``` pub fn f() {}
