Function check_expr_compilation_error

std/src/testutils.rs:1223–1225

Executes `expr` on a scripting interpreter and ensures that evaluation fails with `exp_error` during compilation. Note that `exp_error` is a literal exact match on the formatted error message returned by the machine.

(exp_error: S, expr: &str)

/// Note that `exp_error` is a literal exact match on the formatted error message returned by the
/// machine.
pub fn check_expr_compilation_error<S: Into<String>>(exp_error: S, expr: &str) {
    Tester::default().run(format!("result = {}", expr)).expect_compilation_err(exp_error).check();
