### What is the Wasmite project
Since WebAssembly is the future of the web. I decide to create Wasmite, a python package for unit-testing your wasm or wat code. Wasmite is based on **[wasmer](https://wasmerio.github.io/wasmer-python/api/wasmer/)** and the python standard library package **[unittest](https://docs.python.org/3/library/unittest.html)**. Documentation for can be found here: [documentation for unittest](https://docs.python.org/3/library/unittest.html) and [documentation for wasmer](https://wasmerio.github.io/wasmer-python/api/wasmer/)

**This project was formerly an extension of my Rust/Python Web framework Wasp, so some section of the code may refer to it's earlier name (Native)**

Wasmite looks for tests in python files whose names start with test_\*.py and runs every test_\* function it discovers. The testing folder has more examples.

**Having any problems or questions create a [issue](https://github.com/yusuf8ahmed/Wasmite/issues/new), i will be happy to help :)**

### Installation

This project requires python 3 and doesn't support 3.9
```bash
pip install wasmite
```

### Project Goals:

- [x] Import wasm or wat module successfully
- [x] Access functions within module
- [x] Type checking of parameters and the result of functions
- [x] Release to **PyPi** for public to use
- [x] Allow Wasmite ...
- [x] Export Python functions
- [x] Export Global Instances
- [x] Export Memory Instances
- [x] More complex examples in testing folder
- [ ] Receive community on how to improve

Examples:

* [c++](https://github.com/yusuf8ahmed/Wasmite/tree/master/examples/c%2B%2B)
* [c](https://github.com/yusuf8ahmed/Wasmite/tree/master/examples/c)
* [wasm](https://github.com/yusuf8ahmed/Wasmite/tree/examples/testing/wasm)
* [wat](https://github.com/yusuf8ahmed/Wasmite/tree/examples/testing/wat)

```python
from wasmite import WasmiteCase, WasmModule
from wasmite import FunctionTypes, Function, Global, Value, main
from wasmite import I32

def sum(x: int, y: int) -> int:
""" python function to be imported into WASM """
return x + y

class Test(WasmiteCase):
# create a variable the hold all the functions from a specific wasm file.
module = WasmModule("test_wasm.wasm")
# import python function into WASM
# type annotations on the function is necessary
module.register("math", {
"sum": Function(module.store, sum),
"seven": Global(module.store, Value.i32(7), mutable=True)
})
# start up the module and return the exports (this is mandatory)
exports = module.get_exports()

def test_add(self):
# test add function
result = self.exports.add(1,2)
self.assertEqual(result, 3)

def test_sub(self):
# test the sub function
result = self.exports.sub(2,2)
self.assertEqual(result, 0)

def test_args_add(self):
# check the types for results and parameter of the function "add"
# param is I32, I32 and result is I32
add_function = self.exports.add
self.assertTypes(add_function, FunctionTypes([I32, I32], [I32])) # result will fail

def test_import_sum(self):
# test the imported python function sum.
sum_function = self.exports.addsum(5,2)
self.assertEqual(sum_function, 7)

def test_global_read(self):
# test reading value of global
read_seven = self.exports.read_global()
self.assertEqual(read_seven, 7)

def test_global_write(self):
# test writing value of global
self.exports.write_global(5)
read_seven = self.exports.read_global()
self.assertEqual(read_seven, 5)

# Hi don't forget to add me
if __name__ == "__main__":
main()
```
-->

Then you can then run this test like so:
```bash
# make sure you are in examples/wasm
$ python test_wasm.py

test_add (__main__.Test) ... ok
test_args_add (__main__.Test) ... ok
test_global_read (__main__.Test) ... ok
test_global_write (__main__.Test) ... ok
test_import_sum (__main__.Test) ... ok
test_sub (__main__.Test) ... ok

Ran 6 tests in 0.001s

OK
```
