R: Transform a file an check the result

transform_and_check {styler} | R Documentation

## Transform a file an check the result

### Description

Transform an file and check whether it is identical to a reference.

### Usage

    transform_and_check(in_item, out_item, in_name = in_item,
      out_name = out_item, transformer, write_back, write_tree = NA,
      out_tree = "_tree", ...)

### Arguments

`in_item` | An path to an file to transform.
`out_item` | The path to a file that contains the expected result.
`in_name` | The label of the in_item, defaults to `in_item`.
`out_name` | The label of the out_item, defaults to `out_item`.
`transformer` | A function to apply to the content of `in_item`.
`write_back` | Whether the results of the transformation should be written to the output file.
`write_tree` | Whether or not the tree structure of the test should be computed and written to a file. Note that this needs R >= 3.2 (see `set_arg_write_tree()`). If the argument is set to `NA`, the function determines whether R >= 3.2 is in use and if so, trees will be written.
`out_tree` | Name of tree file if written out.
`...` | Parameters passed to transformer function.
