PYON-BEHAVE | Appium-based UI Automated Testing Framework in Python-Behave for Native Apps

Pyon UI Test Automation project is available to implement UI tests for web and mobile applications with the following stacks and approaches:

• Programming Language: Python-based.
• Framework for behavioural tests: Behave
• Minimal library requirements: Appium Python Client and optionally: Selenium

To know how you can configure your environment to implement and execute this project locally or even remotely, follow all the instructions from this documentation. So, let's get started and good luck!

CLONING THE PROJECT FROM GITHUB

Go to GITHUB and CLONE the project using GIT (download and install GIT from here)

In you local machine, choose you local repository and clone the project using SSH for Mac OS or Linux platforms with this command:

    git clone [email protected]:hudsonssrosa/pyon-behave-ui-tests-nativeapps.git

If you are having issues when cloning or pushing to the repository make sure you have all your SSH keys in place. Click here for more information about it.

PREPARING YOUR ENVIRONMENT

1. Install Python

Download and install the latest Python version (3.8 or over). Then, in any terminal, try this command to check if Python is correctly installed:

      python

2. Choose a good IDE

Once you have opened the project in an IDE of your preference (suggestion: install Visual Studio Code or PyCharm CE), then you will need to set the Python interpreter for the project.

After this, you are able to create the Python Virtual Environment for the PyonUIT project and install all the requirements needed (libraries/packages). You just need to run for the first time the setup_python_env_update.py and then the virtual environment as well the libraries in requirements.txt will be automatically installed for you.

• In Windows:

      python update.py

• In MacOSX or Linux:

      python3 update.py

Increment this command with CLI presented in next section 4.3, if you want to simulate the PyonUIT using Docker.

4. Ways to run this project

By default, the tests will run locally on APPIUM, but you have 3 ways to perform your execution.

4.1 Run in debugging mode

To check if the environment is totally operational to begin with some implementation, or even check the existing tests, you might dealing with the environment variables to prepare for an execution. Thus, copy the file env_settings.properties.local and paste the new one in project's root (in the same place as the original file) renaming it to env_settings.properties. So, you can edit the properties freely, because this file is ignored by GIT versioning.

Into this file, to consider a development setting, ensure the property development_mode is set as true. With this, all the properties that start with debug_... will be considered in a project debugging overwriting any command lines from CLI:

    development_mode = true
    debug_flag_environment = staging

    debug_flag_target = local_emulation
    debug_flag_os = Android
    debug_flag_os_version = 11.0
    debug_flag_device_name = Samsung Galaxy A51
    debug_flag_mode = native_app
    debug_behave_tags = login-sample
    debug_behave_excluded_tags = wip
    debug_flag_orientation = Portrait
    debug_flag_language = en
    debug_flag_locale = en_GB

• To generate Allure Reports locally, make sure you have Java installed and the flag generate_report = true on your env_settings.properties.

4.2 Run as if it were in CI

After any implementation into the PyonUIT, it is recommended to validate the tests simulating an execution capable to inject parameters in environment variables, like it is performed in a build from a CI server. To validate a test execution, keep in mind to run in a remote server such as BrowserStack or any other supported by PyonUIT in fixtures.py. Before this, you also will need to copy the file run_behave.sh.local and paste the new one in project's root (in the same place as the original file) renaming it to run_behave.sh to be ignored in commits.

Into this script file, you can set those environment variables, like this:

    PYON_ENVIRONMENT='staging'
    PYON_TARGET='local_emulation'
    PYON_MODE='native_app'

    PYON_OS='Android'
    PYON_OS_VERSION='11.0'
    PYON_DEVICE='Samsung Galaxy A51'

    PYON_ORIENTATION='Portrait'
    PYON_LANGUAGE='en'
    PYON_LOCALE='en_GB'
    PYON_APP_PATH='.resources/app_distribution/Sample.apk'

    PYON_TAGS=
    PYON_EXCLUDED_TAG='wip'

4.3 Run via CLI (only command line)

You can handle all those parameters presented previously (in section 4.2) setting them directly via CLI. You just need to pass the desired values in the arguments by command line. First of all, call the main runner file in the terminal and press Enter. So, try this:

      python3 behave_runner.py --help

You might see all the supported arguments that you can use:

usage: behave_runner.py [options]

optional arguments:
  -h, --help            show this help message and exit
  --environment {staging,dev,production}

                        ==> Feature(s) / Scenario(s) to be ignored / skipped from execution using a single tag (recommended: wip)

Finally, you can vary the command options such as these samples below and much more. If you does not pass the other arguments, it will be considered the default values:

     python behave_runner.py --target local_emulation
     python behave_runner.py --target local_emulation --os iOS --os_version '14.3' --device_name 'iPhone 12' --orientation Landscape --app_path'.resources\\mobile_automation\\Sample.ipa'
     python behave_runner.py --target bs --mode native_app --os iOS --os_version '14.0' --device_name 'iPhone 11' --app_path '.resources\\mobile_automation\\Sample.ipa'
     python behave_runner.py --target real_device --mode native_app --os Android --os_version '10.0' --device_name 'Samsung Galaxy A51' --tags login-sample --exclude slow

SETUP FOR NATIVE APPS RUNNING LOCALLY

APPIUM CLIENT INSTALLATION

Install Appium Python Client in your local machine to make available the Appium web driver for mobile apps (emulated or real Android / iOS devices connected). Then, just run this Python script to install the Appium Server (check if the version number is presented at the end):

    python appium_setup.py --server install

Open a separated terminal to start the Appium server. You have two ways to run it:

• Via appium_setup.py script, set the host and port if you need (by default it is "0.0.0.0" and "4723", respectively):

    python appium_setup.py --server start

    python appium_setup.py --server start --localhost <YOUR_HOST> --port <YOUR_PORT>

• Or you can execute directly with:

    appium --address <host> --port <number>

1. Appium Desktop

To inspect the device elements in the Appium Client during test implementation, make sure if you have an Appium Desktop. You can download directly from http://appium.io/ Additionally, you need to install Java to make available the Appium client https://java.com/en/download

• Set the environment variable Path for JAVA_HOME:

    export JAVA_HOME=$(/usr/libexec/java_home)

• Use $echo ANDROID_HOME and $echo JAVA_HOME to get values from environment variables and set them in 'Edit Configurations' screen.
• If you want to do this more than once, use the script appium_setup.py.

SETUP FOR LOCAL TESTS UPON iOS DEVICES RUNNING ON LOCAL MOBILE APP PROJECT

If you don't have any iPhone device with you, so you can use the XCode to emulate one. But first is necessary to clone the mobile application project to be tested with.

Follow these steps below (commands for MacOS / Linux) to setup the main resources such as Ruby:

• Install HomeBrew to facilitates the installation for any packages that Linux and MacOS are not able to do.

    /bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)

2. Installing Ruby using RVM

You can install Ruby in different ways. To prevent conflicts and protected Ruby folders, it's recommended to install it using RVM.

2.1. Install GnuPG

    brew install gnupg

2.2. Install GPG keys

    gpg --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

2.3. Install RVM

	\curl -sSL https://get.rvm.io | bash -s stable

2.4. You should receive a thank you 🙏 message in the console

    echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile

2.5. Quit all terminal and open it again

    rvm list

2.6. You should get this message

	# No rvm rubies installed yet. Try 'rvm help install'.

2.7. Install some ruby version

Try a version such as 2.7.1:

    rvm install 2.7.1

2.8. After installation

Check which ruby version available and if is properly installed:

    rvm list

2.9. Create default ruby version

    rvm alias create default 2.7.1

2.10. If installation and configuration were successful

RVM should now load whenever you open a new shell. This can be tested by executing the following command which should output rvm is a function as shown below.

    type rvm | head -n 1

2.11. To change the Ruby version

Just check the versions available:

    rvm list known

2.12. Switching between RVM versions

Then, you can switch to your desired version:

    rvm install 2.6.3
    rvm use 2.6.3
    rvm use system
    rvm alias create default 2.6.3
    ruby -v

3. Installing Ruby - Conventional Way

Install Ruby RBenv using brew and set it to version 2.6.5:

    brew install ruby
    brew install rbenv
    rbenv init
    rbenv rehash
    rbenv install 2.6.5
    rbenv global 2.6.5
    eval "$(rbenv init -)"
    ruby -v
    curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash

• Export the Ruby Path (check the version first) if is not possible to run ruby -v, for example:

    export PATH="/usr/local/opt/ruby/bin:/usr/local/lib/ruby/gems/3.0.0/bin:$PATH"
    echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
    source ~/.bash_profile

• Install Rails to manage the server-side application:

    gem install rails

4. Installing XCode to Manage and Simulate Apps Locally

Download and install the XCode from Mac App Store. Just make sure that your XCode.app is located at "/Applications" folder, otherwise you would see an error such as:

An unknown server-side error occurred while processing the command. Original error: Could not determine iOS SDK version: Could not get Xcode version. /Library/Developer/Info.plist does not exist on disk.

If you continue facing this issue, perhaps you will need to set the correct path from where the Xcode.app is being executed. For example, run this command to find the location:

    xcrun --sdk macosx --show-sdk-path

To switch the SDK reference for Xcode, use this command:

    xcode-select --switch /Applications/

4.1. Dependencies - Installing Ruby Gems

Now, with a mobile app source in a local repository, try to open it using XCode and execute the following commands at the terminal to install the Ruby Gems (dependencies):

    gem install bundler
    bundle install

4.2. Building and Opening the App

Install Carthage to help you in managing dependencies of dependencies in a Cocoa application. Finally, try to open the project via command line:

    brew install carthage
    brew update && brew upgrade carthage
    open <YOUR_APP_NAME>.xcworkspace

4.3. Updating Dependencies for Application Project Builded Locally

If you need to update the dependencies before build any App project cloned into your local machine, it's very important to execute some commands to prevent build errors and clean cached files.

• Clear any cached generated by older project builds:

    rm -rf ~/Library/Developer/Xcode/DerivedData/

• So first open a terminal, and navigate to the App repository. Then update dependencies to Pod:

    cd /Users/<your_pc_user_name>/<path_to_repo>/<local_app_project>
    bundle exec pod install

To see more information about, please, use or check the script setup_local_ios_project.py.

5. Emulating App in the XCode Simulator

Now you are able to emulate any App using XCode Simulator. Just keep in mind these steps:

• Select the SCHEME in the XCode Simulator
• Use the shortkey 'CMD + R' to emulate the app in a device chosen
• At XCode Project Navigator view, select the app in folder where it was build". Then, copy the Full Path presented in File Inspector. This will be useful to set the mobile_app_path property into the env_settings.properties later.

6. Installing FastLane to Simulate using FastFile in CI

If you need to execute the tests externally in a CI Server like Bitrise, you will need to install Fastlane to run it locally and evaluate the FastFile script. So, first install Fastlane using the command below to prevent permission to writeblocks during the installation

    sudo gem install fastlane -n /usr/local/bin
    fastlane -v

5.1. Run the FastFile

Once installed Fastlane, you can run FastFile locally by this command:

    fastlane ios pyon_ui_tests 

If you are facing errors during Fastlane executiong, try to check the log and if you have rspec missed, just try to install this Gem with:

    gem install rspec --user

SETUP FOR LOCAL ANDROID DEVICES

You will need at least the Android Debug Bridge (ADB) to help with test case implementations and debug the app. So follow these steps below:

• Install HomeBrew:

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

• Install ADB:

    brew cask install android-platform-tools

• Export the environment variable Path:

    export ANDROID_HOME="Users/<PC_USER_NAME>/Library/Android/sdk
    export PATH="${PATH}:/$ANDROID_HOME/platform-tools:/$ANDROID_HOME/tools:/$ANDROID_HOME/tools/bin"

• Start using adb.

BDD APROACHING USING PYTHON-BEHAVE

The Behaviour Driven Development can make our automated tests much more agile, productive, sustainable and with a living-documentation of business. Considering this, in the following sections will be presented a step-by-step about how to implement a simple scenario considering Python-Behave (library backed up by Python code - Cucumber-based) and Selenium to make possible to automate our Gherkin scenarios.

HOW TO IMPLEMENT TESTS USING PYONUIT FRAMEWORK?

Considering that the number of tests can increase significantly in this project, it is very important to keep in mind that you also need to have a good and coherent organisation of files, scenarios, features and settings associated to the tests. Initially, to have the codes recognised by Behave framework, all the files related to test cases should be implemented into the features folder. Take a look at the recommended structure below.

1. Gherkin Files

All the tests are documented in Gherkin, a structured and natural language with properly keywords (Given, When, Then) that allows us to write testable specifications. Those files have the format .feature and should be organised into the '/features' with subfolders such as ENVIRONMENT FOLDER (dev/staging/production) > DOMAIN FOLDER (global name of a functionality) > FEATURE FILE. For example:

    features
    └─── feature_domains
        └─── staging
            │   automation_sample_login.feature
            |   ...
            production
            └─── ...

1.1. Create a Feature

With this, you could create a simple scenario that validates if user can search a content in the app. You just need to use the keywords with Feature:, Background:, Scenario:, and describe the behaviours for steps with Given, When and Then:

    @login-sample
    Feature: Automation Sample App

        Scenario: Login the user with its credentials
            Given that app is open at Login page
            When user provides their wrong credentials
            Then user sees "Wrong username or password"

As you could see, add a tag (started with @) trying to choose an easy and intuitive name that reminds you about the Feature. Also, you can include another tag above the scenario, if you want to create new scenarios into the same file. This can make easier to call specific scenarios or an entire feature to be executed via Behave command line.

1.2. Generate the Step definitions

After having a scenario defined, make sure that development_mode is false in env_settings.properties if you want to execute the python3 behave_runner.py --tags login-sample in the terminal (or set development_mode to true and include the tag app-login to property debug_behave_tags). Then, copy the snippet definitions generated automatically in console. You will need to implement your steps using them, like these:

        You can implement step definitions for undefined steps with these snippets:

        @given(u'that app is open at Login page')
        def step_impl(context):
            raise NotImplementedError(u'STEP: Given that app is open at Login page')


        @when(u'user provides their wrong credentials')
        def step_impl(context):
            raise NotImplementedError(u'STEP: When user provides their wrong credentials')


        @then(u'user sees "Wrong username or password"')
        def step_impl(context):
            raise NotImplementedError(u'STEP: Then user sees "Wrong username or password"')

1.3. Create a Step skeleton

Copied the snippets, create a new Python file into the '/features/steps' folder with the same or similar name of your .feature. Try to increment the file name ending with *_steps.py and place them in the steps folder only (to be read by Behave framework).

    features
    └─── steps
        |   app_login_steps.py
            ...

Into this new Python file, you should import behave library to take the advantages of Behave to your Step Implementation.

from behave import *

    # Paste your snippets for steps...

Then, just paste your snippets from clipboard into the search_car_steps.py.

from behave import *


@given(u'that app is open at Login page')
def step_impl(context):
    raise NotImplementedError(u'STEP: Given that app is open at Login page')


@when(u'user provides their wrong credentials')
def step_impl(context):
    raise NotImplementedError(u'STEP: When user provides their wrong credentials')


@then(u'user sees "{error}"')
def step_impl(context):
    raise NotImplementedError(u'STEP: Then user sees "Wrong username or password"')

1.4. Page Object Pattern

Now, you have a basic structure using Behave, but the Steps have no code with the significant actions to cover the behaviour expected in the descriptions. To make this possible, all the interactions with HTML pages might be implemented using Appium/Selenium web driver, coded in Python. So, it is recommended a design pattern such as Page Objects to manage, reuse and store all the locators extracted from a functionality in mobile screen.

Additionally, considering that you will have many app pages to interact in your scenarios, it is very important to let them organised, distiguished by folders and subfolders as well.

In this case, create a file names ending with *_page.py and put them into a folder containing the APP NAME (or a macro app module) > FUNCTIONALITY NAME (or feature name) > PYTHON PAGE OBJECT, like this sample:

    features
    └─── pages
        └─── app_sample
            │   auth_page.py
            │   home_page.py
                ...

At the '/features/pages/' folder, create a new page object class that inherits the BaseAppPage module (from driver_wrappers.appium.native_app_wrapper import BaseAppPage):

from driver_wrappers.appium.native_app_wrapper import BaseAppPage
from appium.webdriver.common.mobileby import MobileBy as MBy


class HomePage(BaseAppPage):
    # ... declare the locators and Appium methods here

Through BaseAppPage, you can take all advantages from default Selenium web driver (to click, type text, etc.) and also consume dozen of wrapped methods customised from the most common component actions identified in an application (get text from an element, select a dropdown option, swipe and many other actions):

    self.wait_for_element(by, location, with_text, title, is_visible, is_not_visible, is_clickable, is_selected, is_frame, is_alert, is_presented, typing_secs, handle_timeout)

    self.get_element_by(by_type, element_location)

    self.get_element_text(by_type, element_location, is_visible)

    self.type_text(input_text, by_type, element_location, is_clickable)

    self.click_on(by_type, element_location, is_visible)

    self.click_on_element_by_accessibility_id(element_location)

    # ... and many others

Considering this, extract the element locators inspecting the application's page opened in Appium Desktop and place them into the variables of your Page Object class. But, you will need to import from appium.webdriver.common.mobileby import MobileBy into the HomePage, to define a kind of locator for a XCUITest element should be able to interpret (MBy.XPATH, MBy.ACCESSIBILITY_ID, By.IOS_UIAUTOMATION, etc.):

from driver_wrappers.appium.native_app_wrapper import BaseAppPage
from appium.webdriver.common.mobileby import MobileBy as MBy


class AuthPage(BaseAppPage):
    loc_lbl_title = (MBy.XPATH, '//android.widget.FrameLayout[1]/android.view.ViewGroup/android.widget.TextView')
    loc_txt_username = (MBy.ID, 'com.dgotlieb.automationsample:id/userName')
    loc_txt_password = (MBy.ID, 'com.dgotlieb.automationsample:id/userPassword')
    loc_btn_login = (MBy.ID, 'com.dgotlieb.automationsample:id/loginButton')
    loc_lbl_error_message = (MBy.ID, 'com.dgotlieb.automationsample:id/errorTV')

The locator declared with a tuple ((MBy.<TYPE>, "<location string>")) can be called directly using asterisk before a self.loc_name.

1.4.a) Assertions

To create validation methods for the steps when is necessary (mainly in the @Then step), you should use the existing assert methods already invoked by BaseAppPage. So, you are able to call them directly into the page used by a scenario. Just define the asserts like these:

• self.assert_that("<FOUND STRING IN PAGE>").is_equals_to("<EXPECTED STRING>", "<OPTIONAL DESCRIPTION>")
• self.assert_that("<FOUND STRING IN PAGE>").contains_the("<EXPECTED STRING>", "<OPTIONAL DESCRIPTION>")
• self.assert_that("<FOUND STRING IN PAGE>").is_different_from("<EXPECTED STRING>", "<OPTIONAL DESCRIPTION>")
• self.assert_that(<FOUND NUMBER IN PAGE>).is_greater_than(b_value=<NUMBER>, "<OPTIONAL DESCRIPTION>")
• self.assert_that(<FOUND NUMBER IN PAGE>).is_less_than(b_value=<NUMBER>, "<OPTIONAL DESCRIPTION>")
• self.assert_that(<FOUND NUMBER IN PAGE>).is_between_the(expected_min=<NUMBER>, expected_max=<NUMBER>, "<OPTIONAL DESCRIPTION>")
• self.assert_that().is_in_pdf("<PDF FILE PATH OR URL>", "<EXPECTED STRING>", "<OPTIONAL DESCRIPTION>")

Then, you should have a page with an implementation like that:

1.5. Step Implementation

Having all the pages needed already implemented, you need to call the methods to satisfy the scenario behaviour, as well the validations.

from behave import *
from features.pages.app_sample.auth_page import AuthPage


login_page = AuthPage(object)


@given('that app is open at Login page')
def step_given_that_app_is_open_at_login_page(context):
    login_page.check_title()


@when('user provides their wrong credentials')
def step_when_user_types_text_to_search(context):
    login_page.type_input_username("wrong_user_name")
    login_page.type_input_password("wrong_pass_123")


@then('user sees "{error}"')
def step_then_the_content_related_is_found(context, error):
    login_page.validate_error_message(message=error)

And your first test case scenario is ready to be executed for the first time!

SELECT THE SCENARIOS TO BE EXECUTED

Regardless if you are using the debug mode to execute tests or triggering them via CI server, you should set the tags accordingly declaring with or without @, but separating them by comma and without spaces. See these examples:

You can combine TAGS like these examples:

• e.g. 1) ISOLATED SCENARIO: demo-app-login

• e.g. 2) COMBINING SCENARIOS: demo-app-login,demo-app-search,...

• e.g. 3) CALLING ENTIRE FEATURES: login-sample

If you leave the parameter related to tags empty, all the features from the environment selected will be executed regardless if is set by properties or by command line.

FURTHER INFORMATION ABOUT CI/CD FILES

If you need to manage or maintain the CI/CD files for PyonUIT, just keep in mind about the following structure.

• JENKINS (Both: iOS and Android): Create all files for environment provisioning, considering the fixtures implemented. Then, create scripts or reuse the existing ones following the steps showed previously in this document. Finally, call the tests in the same way as run_behave.sh file.
• BITRISE (iOS only): Create a Workflow in the Bitrise, integrating the necessary build steps. You need to consider the .fastlane/Fastfile as a last Workflow step into the Workflow configuration. If you need to install Fastlane, follow the README.md in the same folder .fastlane/Fastfile.
