Py3: manual tests on Debian 9

[reszelaz]

This issue is for running manual tests of #1173 on Debian 9. While testing I will try to extend the manual test scenarios.

Installation

• Install Sardana (on Linux from the tar.gz : pip install <tarball_artifact_URL>
  and on Windows from MSI)

Create testing environment and run testsuite

• Start Pool demo2. In a console do Pool demo2.
• Start MacroServer demo2 and connect to the Pool demo2.
  In another console do: MacroServer demo2
• Set MacroServer's MacroPath to point to the macro examples.
  In another IPython console do:
  PyTango.DeviceProxy('macroserver/demo2/1').put_property({'MacroPath':'<path_to_sardana_installation_dir>/macroserver/macros/examples'})
• Restart MacroServer e.g. Ctrl+C in the MacroServer's console and
  start it again.
• Create spock profile demo2. In another console do spock --profile=demo2
• In spock run sar_demo macro.
• Edit <path_to_sardana_installation_dir>/sardanacustomsettings.py
  to point to the demo2 door e.g. UNITTEST_DOOR_NAME = "door/demo2/1"
• Run testsuite. In another console do sardanatestsuite

Test Sardana using Spock and expconf

• Test interactive macros from spock e.g. ask_for_moveable, ask_peak

• Execute umvr macro and verify that the position updates arrives.

• In expconf configure scan files by setting ScanDir to: /tmp/ on Linux
  C:\Users\<username>\tmp on Windows and ScanFile to: demo1.h5, demo1.dat.

• Configure online plot to show counters: On expconf GUI select for all
  the counter channels, Plot Type 'Spectrum' and Plot Axes '<mov>'

• Configure snapshot group: with a motor and the sys/tg_test/1/ampli
  attribute.
  BUG: Drag and drop does not work. One needs to input the attributes manually (remember to use complete URIs)

• Add the sys/tg_test/1/double_scalar attribute to the measurement
  group.
  BUG: Pop-up with the following changes is raised and should not be - expconf shows external changes pop-up when adding external attribute to meas. grp. #1176 (already present in develop)

• Open online plot (This should ask to enable JsonRecorder, set it to true. Otherwise enable it in spock: senv JsonRecorder True).

• Run step scan

• Verify that records appear in spock output.

• Verify that records were stored in scan files.

• Verify that records were plotted on the online plot

• Run showscan and access to the last scan data.
  BUG: most probably due to bug (bytes-string conversion) in PyMCA. Present in PyMCA 5.1.3 but according to @cmft not in PyMCA 5.5. See exception

• With edmac modify existing macro: ask_peak and run it to verify that the change
  was applied.
  BUG: edmac does not appear due to lack of bytes-string conversion

• With edmac create a new macro in a new macro library:
  edmac my_macro <path_to_sardana_installation_dir>/macroserver/macros/examples/my_macros.py
  and run it.

Test Sardana with TaurusGUI

• Create the GUI using this guide
  • Pool name will be: Pool_demo2_1
  • Your element names may be different (depending on free aliases in your Tango database)

PMTV (PoolMotorTaurusValue)

• Move motors from the slit panel in absolute and relative modes.
• Show expert view.
• Show compact mode.

macroexecutor

• Execute ascan macro
• Pause it in the middel and resume
• Abort it
• Add it to favorites
• Run lsm macro
• Execute ascan from favorites
• Run lsmac macro
• Execute ascan from history
• Edit dscan macro in spock yellow line and run it
• Restart macroexecutor application
• Run lsm from history
• Run ascan from favorites

sequencer

• Add ascan macro to the sequence
• Add lsct macro as a post-acq hook of ascan
• Add dscan macro to the sequence
• Run the sequence
• Save sequence to a file
• Start new sequence
  Note: new sequences cannot always be created sequencer action buttons (new & save) state is inconsistent (SF#460) #305
• Load sequence from a files
• Run the loaded sequence

sardanaeditor

Note: There are known bugs on CentOS and Windows

• Open sardanaeditor with macroserver name as argument.
• Browse macro libraries and open an existing macro.
• Edit existing macro and save & apply chaneges.
• Execute macro to see if changes were aplied.
• Create a new macro using template.
• Execute the newly created macro.

MacroButton

• Start macrobutton:

  python3 -m sardana.taurus.qt.qtgui.extra_macroexecutor.macrobutton door_demo2_1

• Execute lsmac macro with default parameter value for filter (.*).
• Execute ascanct macro.
• Execute ascan macro and stop it with the macrobutton (after prior pausing and confirming stopping in the pop-up).

[cmft]

BUG: Drag and drop does not work. One needs to input the attributes manually (remember to use complete URIs)

Fixed

[cmft]

With edmac modify existing macro: ask_peak and run it to verify that the change
was applied.
...
TypeError: a bytes-like object is required, not 'str'

Fixed

The manual tests on Debian 9 are done now. Few issues were discovered and were already fixed by @cmft, thanks!

I have also extended the manual test guide with some tests of MacroButton.

There are the following known issues:

1. online plot does not work - Qwt5 is not ported to python 3
2. showscan does not work with PyMCA 5.1.3 (default package on Debian 9), one needs to install PyMCA 5.5.
3. In order to make the MacroServer environment work properly I was forced to use the gdbm backend of shelve instead of the ndbm. This requires installation of python3-gdbm package.

IMO the tests are satisfactory.
