This package provides support for «golden testing».
A golden test is an IO action that writes its result to a file.
To pass the test, this output file should be identical to the corresponding
«golden» file, which contains the correct result for the test.
To **get started** with golden testing and this library, see
[Introduction to golden testing](https://ro-che.info/articles/2017-12-04-golden-tests).
Command-line options
--------------------
To see the command-line options, run your test suite with `--help`. Here's an
example output:
```

Usage: test [-p|--pattern PATTERN] [-t|--timeout DURATION] [-l|--list-tests]
[-j|--num-threads NUMBER] [-q|--quiet] [--hide-successes]
[--color never|always|auto] [--ansi-tricks ARG] [--accept]
[--no-create] [--size-cutoff n]
[--delete-output never|onpass|always]

expression
-t,--timeout DURATION Timeout for individual tests (suffixes: ms,s,m,h;
