# pytest-embedded
[](https://docs.espressif.com/projects/pytest-embedded/en/latest/?badge=latest) 
A pytest plugin that has multiple services available for various functionalities. Designed for embedded testing.
## Installation
[](https://pypi.org/project/pytest-embedded/)
[](https://pypi.org/project/pytest-embedded-serial/)
[](https://pypi.org/project/pytest-embedded-serial-esp/)
[](https://pypi.org/project/pytest-embedded-idf/)
[](https://pypi.org/project/pytest-embedded-qemu/)
[](https://pypi.org/project/pytest-embedded-arduino/)
[](https://pypi.org/project/pytest-embedded-wokwi/)
Packages under this repo mainly use semantic versioning. Sometimes a bug fix version may contain some non-breaking new features as well.
It is recommended to use `~=1.0` to get rid of breaking changes, and use the latest new features. For example,
```shell
pip install -U pytest-embedded~=1.0
```
## Quickstart
- `pip install -U pytest-embedded~=1.0`
- Create a file `test_basic.py`
```python
from pytest_embedded import Dut
def test_basic_expect(redirect, dut: Dut):
with redirect():
print('this would be redirected')
dut.expect('this')
dut.expect_exact('would')
dut.expect('[be]{2}')
dut.expect_exact('redirected')
```
- Run the test with `pytest`, the result would be like:
```shell
collected 1 item
test_basic.py . [100%]
============================= 1 passed in 0.01s =============================
```
- if run with `pytest -s`, the output would be as follows:
```shell
collected 1 item
test_basic.py 2022-01-01 12:34:56 this would be redirected
.
============================= 1 passed in 0.01s =============================
```
The `print` line is also duplicated to console output.
## Extra Services
You can activate more services with `pytest --embedded-services service[,service]` to enable extra fixtures and functionalities. These services are provided by several optional dependencies. You can install them via `pip` as well.
Available services:
- `serial`: serial port utilities.
- `esp`: auto-detect target/port by [esptool](https://github.com/espressif/esptool).
- `idf`: auto-detect more app info with [ESP-IDF](https://github.com/espressif/esp-idf) specific rules, auto-flash the binary into the target.
- `jtag`: openocd/gdb utilities
- `qemu`: running test cases on QEMU instead of the real target.
- `arduino`: auto-detect more app info with [arduino](https://github.com/arduino/Arduino) specific rules, auto-flash the binary into the target.
- `wokwi`: running test cases with [Wokwi](https://wokwi.com/) instead of the real target.
