He Yin Ling 2b068f3ceb tiny-test-fw: fix misc bugs:
1. configs are not functional
    * decorator will be executed when search case, need to set default config before search case.
2. fix DUT encode/decode errors
    * python3 serial don't support write string/unicode, need to convert to bytes first.
    * python2 string could failed to encode/decode non-acsii chars
3. fix bug that log folder not created
4. fix bug that test suite name is not correctly passed:
    * the keyward arg should be `test_suite_name` not `test_name`
5. fix bug that test stopped on failed case
6. fix DUT `read` don't return all data cache
    * `_DataCache.get_data` should first copy all data from queue to data cache and then return to user.
7. fix bug that `expect_all` failed even all expected item passed
8. optimize error info for expect
    * print pattern for regular expression when match failed
9. fix bug that set default config doesn't work

.. TinyTestFW documentation master file, created by

You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
Welcome to TinyTestFW's documentation!
======================================
We have a lot of test which depends on interact with DUT via communication port.
Usually we send command to the port and then check response to see if the test succeed.
TinyTestFW is designed for such scenarios.
It supports ESP-IDF applications and is able for other applications by writing new bundles.
Test FW features
----------------
1. Test Environment:
1. DUT: DUT provides methods to interact with DUT
* read/write through port
* expect method which supports expect one or multiple string or RegEx
* tool methods provided by the tool bundle, like ``start_app``, ``reset``
2. App:
* provide some specific features to the test application of DUT, for example:
* SDK path
* SDK tools
* application information like partition table, download configs
3. Environment Configs:
* support get env configs from config file or auto-detect from current PC
* provide ``get_variable`` method to get variables
2. allow to customize components (DUT, App) to support different devices
3. Integrate to CI:
* provide interfaces for Gitlab-CI
* provide ``search case`` and ``runner`` interfaces, able to integrate with other CI
Example
-------
Let's first check a simple simple::
import re
import os
import sys
test_fw_path = os.getenv("TEST_FW_PATH")
if test_fw_path:
sys.path.insert(0, test_fw_path)
import TinyFW
from IDF import IDFApp, IDFDUT
@TinyFW.test_method(app=IDFApp.Example, dut=IDFDUT.IDFDUT, env_tag="Example_WIFI",
chip="ESP32", module="examples", execution_time=1)
def test_examples_protocol_https_request(env, extra_data):
"""
steps: |
1. join AP
2. connect to www.howsmyssl.com:443
3. send http request
"""
dut1 = env.get_dut("https_request", "examples/protocols/https_request")
dut1.start_app()
dut1.expect("Connecting to www.howsmyssl.com:443", timeout=30)
dut1.expect("Performing the SSL/TLS handshake")
dut1.expect("Certificate verified.", timeout=15)
dut1.expect_all(re.compile(r"Cipher suite is TLS-ECDHE-RSA-WITH-AES-128-GCM-SHA256"),
"Reading HTTP response",
timeout=20)
dut1.expect(re.compile(r"Completed (\d) requests"))
if __name__ == '__main__':
TinyFW.set_default_config(env_config_file="EnvConfigTemplate.yml")
test_examples_protocol_https_request()
SOP for adding test cases
-------------------------
1. import test framework:
^^^^^^^^^^^^^^^^^^^^^^^^^
* we assume ``TEST_FW_PATH`` is pre-defined before running the tests
* Then we can import python packages and files from ``TEST_FW_PATH``
2. define test case:
^^^^^^^^^^^^^^^^^^^^
1. define test case ``test_xxx(env, extra_data)``
* env: instance of test env, see :doc:`Test Env <Env>` for details
* extra_data: extra data passed from test case caller
2. add decorator for test case
* add decorator ``TinyFW.test_method`` to test method
* define default case configs and filters in decorator, see :doc:`TinyFW.test_method <TinyFW>`
3. execute test cases:
^^^^^^^^^^^^^^^^^^^^^^
* define in ``main`` section and execute from this file
1. set preset configs(optional). If the config is not define in case decorator, it will use the preset configs.
2. call test case method:
* if you don't pass any arguments, it will use default values
* you can pass ``extra_data`` to test case by adding ``extra_data=some_data`` as kwarg of test case method.
default value for extra_data is None.
* you can overwrite test case config by adding them as kwarg of test case method.
It will overwrite preset configs and case default configs.
Examples::
test_examples_protocol_https_request(extra_data=["data1", "data2"], dut=SomeOtherDUT, env_tag="OtherEnv")
* or, use ``runner`` to execute. see :doc:`runner <Runner>` for details

Dependency
==========
Support for both Python2 and Python3 (tested on python 2.7.13 and 3.6.2).
The following 3rd party lib is required:
* pyserial
* pyyaml
* xunitgen
* netifaces
* matplotlib (if use Utility.LineChart)
To build document, we need to install ``Sphinx`` and ``sphinx-rtd-theme`` (you may replace this with your own theme).
