Chapter 1: Getting started withrobotframeworkRemarksThis section provides an overview of what robotframework is, and why a developer might want touse it.It should also mention any large subjects within robotframework, and link out to the related topics.Since the Documentation for robotframework is new, you may need to create initial versions ofthose related topics.VersionsVersionRelease dateRobot Framework 3.0.22017-02-14Robot Framework 3.0.12017-01-06Robot Framework 3.02015-12-31Robot Framework 2.9.22015-10-09Robot Framework 2.9.12015-08-28Robot Framework 2.92015-07-30ExamplesInstallation or SetupDetailed instructions on getting Robot Framework set up or installed.Robot framework is a generic test automation framework.This is implemented using Python and issupported on Python 2 and Python 3 Jython (JVM) and IronPython (.NET) and PyPy.

You can run this executable JAR package from thecommand line like javaava -jar jython installer-.jar.IronPython installationAn installer can be found at http://ironpython.net/download/ for IronPython 2.7.When usingIronPython, an additional dependency is installing elementtree module 1.2.7Configuring PATH & Setting https proxyAdd Python installation directory (by default C:\Python27, C:\Python27\Scripts, C:\jython2.7.0\binetc on windows ) and Scripts directory to the beginning of your path variablehttps://riptutorial.com/3

Value of https proxy should be the URL of the proxy. This is required when these packages areinstalled with pip and you are in a proxy networkInstalling Robot Framework with pipInstall the latest version of robotframeworkpip install robotframeworkInstall a specific versionpip install robotframework 2.0Installing Robot Framework from sourceSource distribution of Robot Framework can be found /downloads.Robot Framework is installed fromsource using Python's standard setup.py script in the source scripts directorypython setup.py installjython setup.py installipy setup.py installInstalling Robot Framework 3.0 on a Windows Machine using Python 2.7.11This is a quick guide to get Robot Framework 3.0 working on a Windows machine using Python2.7.11 - It does not go into too much depth on the why and how, it simply gets you up and running.First things are first, let't go and install Python!1. Download Python 2.7.11 for Windows. (Windows x86-64 MSI installer or Windows x86 MSIinstaller depending on architecture)2. Run through the install, making sure you install "pip" and that you opt in for the "Addpython.exe to Path" (You may have to restart your machine to take advantage of the PythonPATH. In this guide, it presumes you don't have that luxury)3. Once it is installed, let's do a quick check to make sure it installed correctly. Run CMD asadmin and navigate to where Python was installed to cd C:\Python27 and type in python -V. Itshould return "Python 2.7.11"That is it, Python is now installed to your machine. The next part is getting the Robot FrameworkInstalled on your machine using pip.1. First, let's make sure we have the latest version of pip, by first navigating to the scriptsdirectory within Python cd C:\Python27\Scripts and then entering python -m pip installpip. It should say that you have the most up to date version installed!https://riptutorial.com/-U4

2. Next, lets install Robot Framework by entering pipinstall robotframework3. Once pip has finished downloading and installing the files, enter robot --version to makesure it installed correctly. It should say Robot Framework 3.0 (Python 2.7.11 on win32/64)4. (Optional) If in the future there is an update for Robot Framework, you can run this commandpip install --upgrade robotframeworkRead Getting started with robotframework riptutorial.com/5

Chapter 2: How robot framework is used inAutomation testing in Embedded Systems?IntroductionRobot framework is widely used in Automation testing of Embedded products. We are going totake an Embedded product as an example and see how to automate the test cases using RobotFramework.RemarksAbbreviation: RPS - Remote power supply RF - Robot frame workExamplesRemote Power Supply TestingRemote Power supply simulationSince we don't have a real remote power supply hardware, we are going to simulate it usingpython program.Basic idea about RPS Actually remote power supply has a http server. User can send commands to turn ON/OFF power supply using http request.We are going to simulate remote power supply using following program rps-server.py.from flask import Flask, requestfrom flask httpauth import HTTPBasicAuthapp Flask( name )auth HTTPBasicAuth()users {'admin': '12345678'}app.url map.strict slashes FalsePINS ['P60', 'P61', 'P62', 'P63']https://riptutorial.com/6

PINS STATUS {'P60':'0', 'P61': '0', 'P62':'0', 'P63':'0'}@auth.get passworddef get pw(username):if username in users:return users.get(username)return None@app.route('/')@auth.login requireddef index():return "Hello, %s!" % auth.username()def get html string():html str ' html P60 {}P61 {}P62 {}P63 {} /html '.format(PINS STATUS['P60'],PINS STATUS['P61'],PINS STATUS['P62'],PINS STATUS['P63'])return html strdef parse cmd args(args):global current statusif str(args['CMD']) 'SetPower':for key in args:if key in PINS:PINS STATUS[key] str(args[key])return get html string()if str(args['CMD']) 'GetPower':return get html string()@app.route('/SetCmd', methods ['GET','POST'])def rps():if request.method "GET":args request.args.to dict()ret parse cmd args(args)return retThe above code actually simulates http server to control the remote power supply.How to Run RPS server ? export FLASK APP rps-server.py flask runHow to send commands to rps server ?Following are the two commands used to control the RPS1. SetPower2. GetPowerBy default the server will be listening at the port 5000.https://riptutorial.com/7

The power supply ports are,1. P602. P613. P624. P64The states of the ports are,1. ON - 12. OFF - 0RequirementsRequirements for building a remote power supply are1. Remote power supply should be able to turn ON/OFF remotely2. Remote power supply status can be accessed remotely.Deriving test casesTest cases derived from requirement1. Turn on Power supply 2 remotely.2. Verify power supply 2 is on.3. Turn off Power supply 2 remotely.4. Verify power supply 2 is off.Manual Testing Run the rps server. To turn on Port 3, open a browser and give following URIhttp://admin:12345678@localhost:5000/SetCmd?CMD SetPower&P62 1 To get the status of all the MD GetPowerWriting test libraryWe need to write a test library in python for sending http commands using http request. Later wewill be using this library as keywords in robot frame work.commands.pyhttps://riptutorial.com/8

We are going to use library from commands.py to send SetPower and GetPower.import requestsimport reclass commands(object):ROBOT LIBRARY SCOPE 'GLOBAL'def init (self, ip 'localhost:5000'):self.ip address ipself.query {}self.user 'admin'self.passw '12345678'def form query(self, state, cmd, port):port self.get port no(port)self.query {port: state}return self.querydef get port no(self, port no):port 'P6' str(port no)return portdef clean html(self, data):exp re.compile(' .*?

2. While using this function in Robot key word, no need to bother about , or Lowercaser orUppercase in function name.Python function will look like this while using as keyword,Send CmdscmdportstateWriting test KeywordsWe are going to use SendCmdsas python keyword in test suite. RPS send commands uses following four arguments to set power command SetPowerport 2state 1 for ON / 0 for off When we call that command it will turn ON/OFF the powersupply RPS get power will return the status of all the Power supply ports*** Keywords ***RPS send commands[Arguments] {command} {output} Send cmds[return] {output}RPS get Power[Arguments] {command} {output} Send cmds[return] {output}} {port} {command} {state} {port} {state} {command}Algorithm to test power supply1. Set power to a port2. Check the status of cmd3. Get the status of the port and check whether it is ON/OFFWriting test cases using the above key wordsNow we are ready to write test case using following two keywords RPS send commands - To set and unset a power of port RPS get power - To get the status of all the port*** Settings ***Librarycommands.py*** Test Cases ***Turn on Power supply 2 remotely {out} RPS send commandshttps://riptutorial.com/SetPower2110
