# Function ring::test::from_file [−] [src]

    pub fn from_file<F>(test_data_relative_file_path: &str, f: F) where
        F: FnMut(&str, &mut TestCase) -> Result<(), Unspecified>,

Reads test cases out of the file with the path given by `test_data_relative_file_path`, calling `f` on each vector until `f` fails or until all the test vectors have been read. `f` can indicate failure either by returning `Err()` or by panicking.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
