Provola, provalo, just test it!
provola
is your best ~~cheese~~ friend when you need to test code quickly.
Just create an input file, an expected output file and a program digest the
input and provola
will test your program automatically whenever
you change the code.
```shell
echo 'main = interact reverse' > reverse.hs
echo -n abcd > in.txt
echo -n dcba > out.txt
provola -i in.txt -o out.txt -s reverse.hs -w . ```
provola
provides shell autocompletion for even faster usage.
You can install autocompletion for yout favourite shell:
shell
provola --generate zsh > ~/.zfunc/_provola
