Provola

~~Test it!~~ → ~~Provalo!~~ → Provola!

provola is your best ~~cheese~~ friend when you need to test code quickly.

Input/Output test

Just create an input file, an expected output file and a program to digest the input and provola will test your program automatically whenever you change the code.

```shell

Create a simple haskell program

echo 'main = interact reverse' > reverse.hs

An input for your nice program

echo -n abcd > in.txt

The expected output

echo -n dcba > out.txt

Run provola!

provola -i in.txt -o out.txt -s reverse.hs -w . ```

Where:

• -i is the input file
• -o is the expected output file
• -s is the source code
• -w is the file or directory to watch for changes

Supported languages

| Language | Build | Run | |------------|-------------|----------| | Bash | / | ✓ | | C++ | gcc | ✓ | | C | gcc | ✓ | | Haskell | stack ghc | ✓ | | JavaScript | | ✓ node | | PHP | | ✓ | | Python | | ✓ | | Rust | rustc | ✓ |

Test frameworks

provola is able to use test runners generated by popular test frameworks.

Example:

shell provola -T GoogleTest -t path/to/gtest/executable

Where:

• -T is the test runner type (e.g.: GoogleTest, Catch2, ...)
• -t is the executable to run

You don't need to specify what files to watch, because in this case provola is automatically watching changes in the test runner (not the sources!).

You can also find an example of GoogleTest runner inside provola-googletest/examples/data/

This is a (work in progress) list of supported frameworks:

| Framework | Language | |-------------|----------| | Google Test | C++ | | Catch2 | C++ |

Install

If you have a rust toolchain, just clone this project and from the root directory:

shell cargo install --path .

egui feature, which provides a GUI, is enabled by default. You can disable it:

shell cargo install --no-default-features --path .

Arch Linux

You can install the provola package from aur:

shell yay -S provola

Shell auto completion

provola provides shell autocompletion for even faster usage.

You can install autocompletion for yout favourite shell:

shell provola --shell-compl zsh > ~/.zfunc/_provola
