Installing Ride on Pi Zero

Posted on 10/20/201901/29/2020 by Andie Tanadi

Installing Ride v1.7.4 on Raspberry Pi Zero with Raspbian is a Challenge, especially during preperation and installation of wxPython for pi Zero

Base setup from pi Zero:

Rasbian buster lite
python 3.7x

Do SW update before installing :

sudo apt-get update
sudo apt-get upgrade
sudo apt get dist-upgrade

Do Install pip3 for my pi zero:

sudo apt-get install python3-pip

Prepare installation before installing wxPython on pi Zero:

sudo apt-get install dpkg-dev build-essential swig python-dev libwebkit-dev libjpeg-dev libtiff-dev checkinstall freeglut3 freeglut3-dev libgtk2.0-dev  libsdl1.2-dev libgstreamer-plugins-base0.10-dev libgstreamer0.10-dev libgconf2-dev libglapi-mesa libosmesa6 libglu1-mesa-dev libglu1-mesa mesa-common-dev

sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev

sudo apt-get install python3.7-dev

sudo apt-get install python-wxgtk2.8 python-wxtools wx2.8-i18n libwxgtk2.8-dev libgtk2.0-dev

sudo apt-get install gtk+-3.0 gtk+3.0-dev

sudo pip3 install pathlib2

Now install wxPython, it can take long (+/- 24 Hours) by pi Zero!

sudo pip3 install wxPython

If it’t passed you can install Ride !

sudo pip3 install --upgrade robotframework-ride

You can start the Ride now as remote sessions:

Raspberry Pi & Robotframework

Posted on 03/14/201903/14/2019 by Andie Tanadi

Raspberry Zero W connected directly to Mac with OTG mode

Why using Robotframework on Raspberry pi?

As Raspberry pi user , sometimes I have problems after doing OS update with some application I currently workout on pi, mean do “sudo apt-get update” , “sudo apt-get upgrade” & do “Reboot” everythings goes Wrong 🙁 !.

I have been using Robotframework since 2006, and would like to show you how simple to run a Regresion Test with Robotframework Framework on SBC like Rasberry Pi and Co’s. Robotframe work need only python ecosystem, which are out of the box delivered by Raspbian OS. And also it needs minimal resource of space in SD card.

Used pi space before Robotframework Installation

As a sample I will start with installation of Robotframework , please check before if you have python pip installer installed on your Rasbian before starting with the installation!

Start Installation of Robotframework on Pi

sudo apt-get install python3-pip
sudo pip3 install robotframework

Check Robotframework runner:

robot --version

Robotframework runner OK

You can used nano or Test IDE Ride for writing Tests .

Installing Robotframework-RIDE test IDE:

sudo pip3 install robotframework-ride

Start RIDE on Mac with ssh conection to pi:

ride.py &

Running Robotframework-RIDE for testing Temperature Sensore Interface on Pi

now you can start writing your Test, please refer to Robotframework manual for more Information.

Let check the SD card used for Robotframework Installation, just 1% from 16 GB SD card!

Used pi space after Robotframework Installation

Wish you happy Testing and Try Out!

Testing Soap interface with Robotframework Library

Posted on 02/14/201903/14/2019 by Andie Tanadi

For efficient testing sometime you need to created automaticaly request xml feeding soap interface. If you are familiar with robot framework, it’s great. Robotframework has already 2 external Library, which handle SOAP interfaces communication.( Süds Library or Zeep Library ) .

There are a lot of opinion in Internet about these two libraries, discussing pro and contra using one of these lib. for testing SOAP.

Important things to do, you have to find out which library can handle “your WSDL“ better!

For my task, Suds library does.

How to find it out?

Just run your SOAP Library keyword pointing out your target WSDL .

Used “Create Soap Client” keyword for testing the binding if you get all the entities and objects on your WSDL, If the answed “OK” than you can used your Library for SOAP,

…
Ports (1):
….
Methods (10):
addToIndex(xs:string guid, )
getProductMetadaten(xs:string guid, )
getProductMetadatenGuidList(xs:string query, )
getProductMetadatenList()
…
Types (62):
ns3:AbstractCurveType
ns3:AbstractGMLType
ns3:AbstractGeometricAggregateType
ns3:AbstractGeometricPrimitiveType
…

If not you have to find out other library for interfacing with SOAP.

As sample I got these error using Zeep for parsing my WSDL:

self.item_type = self.item_type.resolve()
AttributeError: ‘lxml.etree.QName’ object has no attribute ‘resolve’

These error are related to these following open issue on Zeep:

Sample of created XML request from RF with Suds Library:

XML Request Created with RF & SUD from input WSDL

this is how I wrote it in Robotframework Test Suite:


map WSDL local
Run Keyword and Continue On Failure	setProductMetadaten

this is how I wrote it in Robotframework Test Case:


show object setProductMetadaten
setProductMetadaten

calling internal keyword:


${object}=	Create WSDL Object	n2:ProductMetadata
Set Wsdl Object Attribut	${object.commonMetadata}	identifier	${dummy_text}
Set Wsdl Object Attribut	${object.commonMetadata}	title	${dummy_text}
Set Wsdl Object Attribut	${object.commonMetadata.description}	summary	${dummy_text}
Set Wsdl Object Attribut	${object.commonMetadata.description}	comments	${dummy_text}
Set Wsdl Object Attribut	${object.commonMetadata.product}	type	${dummy_text}
Set Wsdl Object Attribut	${object.commonMetadata.product}	subtype	${dummy_text}
Set Wsdl Object Attribut	${object.commonMetadata}	rflAuftragsnummer	${dummy_text}
Set Wsdl Object Attribut	${object.commonMetadata.change}	version	${dummy_text}
${result}=	call Soap method	setProductMetadaten	${object}

RFlog result

Creating 100X Request with RF For loop keyword


map WSDL local
:FOR	${i}	IN RANGE 100
	setProductMetadaten

Hope these infos help you starting your SOAP request creation with Robotframework & SudsLibrary, just another way of SOAP testing than using SOAPUI.

Custom PB4 (shorted)

Posted on 01/04/201908/15/2021 by Andie Tanadi

Below PB4 adalah assesori nikon yang saya gunakan untuk pemotretan macro atau pemandangan.
Kelebihan dari below ini dibandingkan dengan below nikon yang lain adalah kemampuan untuk shift serta tilt, sehingga anda dapat mengatur DOF sesuai yang anda inginkan dalam komposisi gambar anda. Ini adalah solusi saya sebelum ada lensa Tilt & Shift dari Nikon.

Below ini di perpendek sampai scala 10 cm dari ukuran asalnya untuk mempermudah handling pemotretan.

lensa ini biasanya saya pakai dengan lensa:

Below Tessar 50mm/2,8
Enlager Lens EL Nikkor APO 135mm/5,6
Olympus Zuiko Auto1:1 80mm/4

Dengan PS4 sebagai Slide Copy

Modifikasi lebih lanjut untuk dipakai dengan digital kamera silahkan dilihat disini

Custom Tripod Mount for Nikon 80-200mm f/2.8 AF-D ED

Posted on 01/04/201908/15/2021 by Andie Tanadi

Lensa Zoom Nikkor ini adalah lensa AFD Zoom Nikon satu satunya yang saya sering gunakan untuk pengambilan gambar dengan kamera Nikon Analog saya, lensa ini mempunyai ring Fokus yang menyatu dengan Ring Zoom, sehingga memudahkan , mengatur posisi fokus secara manual pada kamera anda.

Sayangnya lensa ini tidak mempunyai Tripod mount, untuk pengambilan foto tertentu, sekiranya anda harus menggunakan Tripod, tidak mungkin anda menggunakan mounting yang ada di Body kamera anda untuk menyangga kamera dengan lensa ini di Tripod.

Untuk itu saya menggunakan Adapter untuk Tripod mount dari Firma Burzynski, dengan custom adapter ini anda dapat menggunakan kamera ini dengan format Vertikal dan horisontal pada Tripod Tanpa kesulitan, Lens Hood juga dapat anda gunakan seperti biasa, Fungsi kamera juga tidak terganggu untuk manual Focus tanpa tripod.

Juga anda dapat menggunakan Case Original Nikon untuk menyimpan lensa ini !

Mounting Part juga sudah menggunakan standart quick release dari Arca Swiss.

Nikon FG20

Posted on 01/04/201908/15/2021 by Andie Tanadi

Akhir Tahun 2018 saya menerima pemberian Nikon body FG20 dan lensa Zoom- 35-105mm Nikkor /3,5-4.5 dari mertua saya.
alasan dia adalah karena dia sudah tidak lagi menggunakan kamera analog ini.

Sekilas saya melihat langsung & tertarik sekali dengan prinsip dasar yang dibuat untuk kamera ini, sangat sederhana, dalam fungsi dan penggunaan, terlebih lebih setelah lensa saya ganti dengan lensa Tokina 20-35mm dengan rana 2,8 , Tiba tiba finder nya menjadi terang sekali lebih nyaman dipakai dibandingkan dengan finder finder yang anda bisa temukan di kamera digital jaman kini.

Lensa Zoom- 35-105mm Nikkor /3,5-4.5 , juga saya pasangkan ke nikon F4 E saya, dengan body F4 , anda dapat memakai Spot dan matrix mettering dengan lensa ini!

Dengan lensa Voigländer Ultron 40mm/2.0 , kamera ini menjadi sangat kompak,

Testing MS Software Rollout with Python ,WMI, and LDAP3

Posted on 12/05/201803/18/2019 by Andie Tanadi

Most MS (Microsoft) software roll-out are release via SCCM to all Project Infrastructure (DC, AD, Application Servers, Application Clients). Usually testers are using Standards MS Tools like Powershell, MS CMD (tools: like netsh, wmic, etc) for validating Installation results on targets.

This article describe how the same tasks solve with python scripting using WMI & LDAP3 library.

Common Test Task & Rollout Workflow:

Rollout related Packages will be distributed to MS SCCM
Over SCCM Application GUI Testers trigger the release processes for target environment (Server/Client PC)
On target environments testers mock up the sccm client update sequence to push roll-up update for related Packages.
After SCCM agent invoke successfully SW update, the validation steps starting, Testers use common MS OS GUI like “Software Information GUI” or “Service Information GUI ” for validating Installation status. Some Testers also used Powershell commands for Validating installations.

Just daily tasks for MS Administrator , as test analyst , I try to find out more efficient way.

After some investigation I find out, the way validating MS SW status over WMI Interfaces are much easier than any Powershell or Dos Batch command, especially with pywmi.

These following WMI class Objects are interesting for SW Installations
Validation :

Win32_OperatingSystem
Win32_Product
Win32_BaseService
Win32_Service
Win32_NTDomain
win32_optionalfeature
win32_ComputerSystem
Win32_PingStatus

Using pywmi, ldap3, winkerberos and common Excel library on python, I created scripts which extract the installed SW, Services Status, Drive Mapping , Domain configuration and AD Application User Accounts. All as excel files containing Tabs related to the mentions check Topics.

WMI exe’s
WMI results

Status, Drive Mapping , Domain configuration and AD Application User Accounts. All as excel files containing Tabs related to the mentions check Topics

AD exe’s
AD results

I Run it before SW update and after Update, find out the delta Information’s I got in my excel sheet and cross check if all Items match to release roll-out specifications.

Added Value:

The script can be pointed for remote Target using WMI remote functionality.
Limited scripts to do only wmi-get / LDAP show action (under executable) , to guaranties that no system or installation change cause by test action.
Validating more easier than with MS Scripting( I created “.exe” files for each test with py2exe)
I don’t mess any test object, because no installation for python needed (all checks are run as “.exe” files and can easily remove after test)

MS Powershell 6 dengan Raspberry Pi2 / Pi3

Posted on 10/24/201803/14/2019 by Andie Tanadi

Untuk rekan rekan yang bergerak(bekerja) sebagai windows system administrator tentu anda mengenal Powershell yang selama ini digunakan untuk mengadministrasikan MS Windows OS.

Sejak Versi Powershell 6 (Core) tertanggal
23.08.2018 anda dapat menjalankan semua Powershell script (.PS1) tidak saja dari Windows PC tetapi dari semua system OS (Lin(x) atau MAC).

coba bayangkan betapa besar kemungkinan implementasi yang anda dapatkan (administrasi & test MS-SCCM, -SCOM ,dll lewat raspberry) !

limitasi: untuk saat ini Powershell 6 (Core) hanya berfungsi dengan pi2 atau pi3, tidak pada Pi Zero.

Untuk informasi instalasi di OS Rasbian(Stretch) silahkan lihat disini

Untuk informasi instalasi wmic id lin(x) silahkan lihat di sini
