Steeltoe Sample Application Tests

Using the behave Wrappers

The Samples tests are run using behave, a Cucumber-style BDD framework written in Python. This project's behave implementation requires Python 3. See Installing Python 3 for platform-specific instructions.

Two helper scripts, behave.ps1 and behave.sh, are provided to simplify the setup and invocation of behave. These wrappers:

1. install pipenv into the user's Python package install directory
2. create a Python virtual environment for the project using pipenv
3. install needed Python packages into the virtual environment
4. invoke behave in the virtual environment

Steps 1-3 are only run if necessary (typically the first run). To force the wrapper scripts to re-run steps 1-3, create an empty file named reinit in the project root and rerun the wrapper.

Any arguments and parameters passed to a wrapper are subsequently passed to behave.

As an example, the following displays the help for behave:

C:> .\behave.ps1 -h

Running with no arguments will run every sample for every framework/runtime combination.

C:> .\behave.ps1

To run a specific sample, pass the path to the sample:

C:> .\behave.ps1 Connectors\src\RabbitMQ

To run only a specific framework/runtime combination, use the --tags or -t parameter:

C:> .\behave.ps1 Connectors\src\RabbitMQ -t netcoreapp2.1 -t ubuntu.16.04-x64

Configuring

Create a user.ini file in the project root directory. An example file, user.ini.example, is provided as a convenience.

C:> copy user.ini.example user.ini

The example file's options are commented with descriptions.

One option you might want to enable is windowed = yes. Setting this option will run backgrounded processes in their own dedicated windows, making it easier to follow a test's progress.

Cloud Foundry

If you don't specify Clound Foundry credentials, it is assumed you are already logged in to a Cloud Foundry endpoint.

You can configure credentials by setting the following options in user.ini:

• cf_apiurl
• cf_username
• cf_password
• cf_org

Sample:

[behave.userdata]
cf_apiurl = https://api.run.pcfone.io
cf_username = myuser
cf_password = mypass
cf_org = p-steeltoe

It is expected that a Cloud Foundry space named development exists for the configured credentials. The development space will be used as the target from which to create additional spaces for running tests.

By default, each sample will use a dedicated space for its applications and services. The space is named {feature}-{sample}-{os} where:

• {feature} is the feature name (the top directory node of the sample path)
• {sample} is the sample name (the bottom directory node of the sample path)
• {os} is one of: windows, osx, linux depending on the platform on which the tests are run

As an example, if running the sample Connectors\src\RabbitMQ on Windows, it will use the space connectors-rabbitmq-windows.

You can override this behavior by setting the cf_space option.

cf_space = myspace

Installing Python 3

Running the Samples tests requires Python 3 and its corresponding pip package manager.

Windows

Install Chocolatey.

Start a PowerShell as Administrator and run:

C:> choco install -y python3

OS X

Install Homebrew.

Start a terminal and run:

$ brew install python3

Ubuntu

Start a terminal and run:

$ sudo apt install -y python3 python3-pip
