Using 'sudo pip install' can cause a lot of problems because usually
there are a couple of Python interpreters installed. This fix encourages
developers to use `pip install --user` instead which is safer.
We found some SD card on Raspberry Pi could have very bad performance.
It could take seconds to save small amount of data.
If the DUT receives data and save it as log, then it stops receiving data until log is saved.
This could lead to expect timeout. As an workaround to this issue,
``BaseDUT`` class will create a thread to save logs.
Then data will be passed to ``expect`` as soon as received.
This change allows readonly FATFS to be mounted without wear levelling
support. This will provide the customers a simple way to mount FATFS images
generated on host and flashed onto the chip during factory provisioning.
Since NVS encryption is not supported yet and NVS entry size is limited,
the change will provide an easy alternative for securing the provisioning data
by just marking FATFS parition as encrypted.
Will give hint when any job failed to assign:
```
Please add the following jobs to .gitlab-ci.yml with specific tags:
* Add job with: psram, ESP32_IDF, UT_T1_1
* Add job with: psram, ESP32_IDF, UT_T1_1
```
We have built unit-test-app with different configs.
Currently we use the config name as tags to match runners.
It's not easy to add new configs (need to update tags to existed runners).
Now we'll parse required test runner tags from `sdkconfig` file.
For example, if config enables `CONFIG_SPIRAM_SUPPORT`, then it requires `psram` tag.
This will make adding new configs easier.
In this commit we change the one behavior of assign test: match keys of
cases should be exactly the same with job tags. This fixes cases select
jobs include their tags, and jobs requires those tags can't be assigned.
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
1. Attenuator: control programmable attenuator
2. PowerControl: control APC PDU to power on/off devices
3. LineChart: use matplotlib to draw line chart
