Working with spring properties and profiles

sptingbootMaven

Today I have a very simple application for you to demonstrate how to use profiles to control environmental variables.

To skip the build and access the code, you can find it here:

https://github.com/suveerprithipal/spring_properties_and_profiles

Lets keep going.

Why do we want this?

So we can swap profiles when testing locally vs a cloud or dev vs test

How do we build this?

Firstly, we need to create an environmental variable. To do so, on windows10,

On windows desktop, Search for “advanced system settings”

Windows_Search_Advanced_system_settings

Select ‘Advanced system settings’

Advanced_system_settings

  • Click Environment Variable
  • Click “New” under ‘System Variables’
  • Set Variable name of ‘APP_URL’
  • Set Variable value of ‘cloud’

add_system_var

 

 

 

 

 

 

 

 

 

Next up I created a Maven project and added in my Spring boot dependencies. We then need to create some profiles. Easy peasy. To do so, we actually create properties files. Yep, that simple. Under your java/test filepath, create a resources dir. Remember to right click and mark as ‘test Resources Root’ Create 2 properties files:

  • properties-local.properites
  • properties-cloud.properties

adding_properites_files

In each of them, add a variable called ‘my.app.url’ as the following demonstrates.

in properties-local.properites: my.app.url = local

local_props
in properties-cloud.properites: my.app.url = ${app_url}

cloud_props

We use “${app_url}” here as we want to point our test to use the system variable we created. When springboot runs, and see’s “${}” it knows to go looking for a definition on that variable on the system.

We’re almost done! and now in a position to add some tests to access these variables we’ve created above.. Create a test or use the one created by default if you have one.

In our test class, create a class member of type ‘Environment'(org.springframework.core.env.Environment). I called mine “env”. Don’t forget to Autowire(org.springframework.beans.factory.annotation.Autowired) this member as we want a bean created for this at run-time.

We create 2 tests:

  • localTest
  • cloudTest

testclass

These are very similar in nature, but have 2 different asserts:

  • localTest Assert.assertEquals(“local”, env.getProperty(“my.app.url”));
  • cloudTest Assert.assertEquals(“cloud”, env.getProperty(“my.app.url”));

Lastly, we want to specify which profile spring should use when running. To do this, we will add a VM Option to the Run Configuration.

I ran my 2 tests above individually. This create a run configuration for me automatically. I then go to edit these configs.

  • localTest Run config: I set the VM option to : -Dspring.profiles.active=local Apply and save.
  • cloudTest Run config: I set the VM option to : -Dspring.profiles.active=cloud Apply and save.

runconfig

Now when we run these, spring will swap out our properties file, based on the profile we selected. You will see that the local env.getProperty will return “local” and cloud env.getProperty will return cloud, which we set on the system.

That’s it! You’re done! Happy Testing.

Functional testing: Numbers vs Coverage

team-success-1600x700

Functional test automation.  It’s not entirely about the numbers, but rather the value and coverage of the test you create.

Push left. Cover more in unit/integration tests and less on the UI. Try not to look at this as it takes away from you as a tester’ but rather enhances your ability, exposure and experience.

Its difficult to decide which tests to push left you say?

Yes, I can definitely agree with that. I was hard for me too.

I’ve learnt that this difficulty comes strong at first but when this is a practice we bake into our planning sessions, this becomes easier with time. Communication is the most important influence here. The results of which will lend to a “Team Test Approach” or “Quality mindful team”.

 

 

 

Are you BDDing?

There are many ways in which we can scribe out a feature file. In my experience with teams of various experience, businesses of different maturity and a variety of complexity of applications I have learned there is no 1 way to get this right.

Here are 7 things to remember:

  • Don’t just use the tool but use the tool well. Stick to the reasons why we use a ‘Given’, ‘When’ and ‘Then’
  • Remove test data setup from your scenarios. If you need to ready your env for test, treat it as a separate concern.
  • Tags, tag everything. This is a great way to ensure we run specific tests and deliver faster feedback when you are faced with a time sensitive roll-out.
  • A short scenario is a good scenario.
  • You scenario’s aren’t cast in stone. Revise and revisit.
  • Maturing your BDD is really important. Its living documentation and is ultimately a reflection on our understanding of the application and our drive for high quality applications.
  • Share it with your team. Make your team quality conscious. Have them revise it at regular intervals…make it a thing.

Building a Test Automation Framework

automated-testing-best-practices-agile

Spent a wet weekend indoors and decided to spin up a testing framework.  Here is my top 11.

What’s in it?

Java 8 Maven Spring Application.   + Cucumber + Selenium + Restful API Test Automation Framework + Postgres + Spring JPA.   This setup included :

  • Restful Api call and testing using RestTemplates and a Pojo for modelling the Json.
  • BDD with Cucumber for Feature
  • Webdriver   
  • Docker
  • Postgres Db   
  • Spring JPA   
  • Swagger Api Documentation
  • Rest Assured   
  • Page Object Modelling   
  • Saucelabs integration
  • Tomcat – Standard with Spring

What else should I add in here?
