Title description can not have the same content as a importe

Error message

Title description can not have the same content as a imported function name.

What it means

Emitted by the vitest/prefer-describe-function-title rule when a `describe` title string exactly matches the name of an imported function. It fires because the title likely interpolates or shadows the identifier incorrectly — either the function itself should be passed as the title or the string should differ, otherwise the test name is misleading.

    /// ### What it does
    ///
    /// When testing a specific function, this rule aims to enforce passing a named function to `describe()`
    /// instead of an equivalent hardcoded string.
    ///
    /// ### Why is this bad?
    ///
    /// For tests that are related to a specific function, if the function being tested is renamed,
    /// the describe title will no longer match and can cause confusion in the future. Using the function
    /// directly ensures consistency even if the function is renamed.

Solutions

1. Pass the imported function directly as the title argument, e.g. `describe(myFn, () => {...})`
2. Rename the title string so it does not duplicate an imported function name
