## Usage

The default path to your project is `..` but you can change it the the [configuration](src/config.py).

```sh
$ ./run`  # run all tests

$ ./run --help`
usage: run [-h] [-v] [-b] [-n] [-l] [-m] [-p] [suite [suite ...]]

Minishell test

positional arguments:
  suite           Test suites/group to run.
                  It tries to be smart and autocomplete the suite name
                  (e.g ./run int -> ./run preprocess/interpolation)

optional arguments:
  -h, --help      show this help message and exit
  -v, --verbose   Increase verbosity level (e.g -vv == 2)
  -b, --bonus     Enable bonus tests
  -n, --no-bonus  Disable bonus tests
  -l, --list      Print available test suites
  -m, --make      Make minishell and exit
  -p, --pager     After running the test, display the result in a pager of your choice
```

## Test compatibility

Your executable **must** support the `-c` option which allow to pass command as string.

```sh
$ bash -c 'echo bonjour je suis'
bonjour je suis
$ ./minishell -c 'echo bonjour je suis'
bonjour je suis

$ bash -c 'ls'
README.md test.sh
$ ./minishell -c 'ls'
README.md test.sh
```

This allows you to set the prompt to whatever you want.

This test works with python >= 3.5.

## Bonus

Their is 3 different method to enable the bonus tests:

* Force the bonus tests with `./run -b`
* Change the `BONUS` variable in [config.py](src/config.py) to True
* Set the environment variable `MINISHELL_TEST_BONUS` to `yes`  
  (e.g `echo 'export MINISHELL_TEST_BONUS=yes' >> ~/.zshrc`)

## Add new tests

### Add individual test

In your suite function you can use the `test` function. With the following arguments:

1. Command to be tested (output and status will be compared to bash)
2. A command to setup the sandbox directory where the tested command will be run
3. List of files to watch (the content of each file will be compared)

```python
test("echo bonjour je suis")                                  # simple command
test("cat < somefile", setup="echo file content > somefile")  # setup
test("ls > somefile", setup="", files=["somefile"])           # watch a file
test("echo $A", exports={"A": "a"})                           # export variables in the environment

test("cat < somefile > otherfile",
     setup="echo file content > somefile",
     files=["otherfile"])
```

### Add Suite

A test suite is a group of related tests.

```python
@suite()  # @suite(bonus=True) if it's a bonus suite
def suite_yoursuitename(test):
    test(...)
    test(...)
    test(...)
```
