/// * [required] `module.wat` - contains the core module definition to be encoded
/// as a component.
/// * [optional] `default.wit` - represents the component's default interface.
/// * [optional] `export-<name>.wit` - represents an interface exported by the component.
/// * [optional] `import-<name>.wit` - represents an interface imported by the component.

/// And the output files are one of the following:

/// * `component.wat` - the expected encoded component in text format if the encoding
/// is expected to succeed.
/// * `error.txt` - the expected error message if the encoding is expected to fail.

/// Run the test with the environment variable `BLESS` set to update
