Achieving Advanced BDD Test Automation: An In-Depth Guide

Hi there! As someone with over 10 years of experience testing complex software systems, I‘m thrilled to take you on a deep dive into advanced test automation techniques. Specifically, we‘ll focus on behavior‐driven development (BDD) – a process that improves collaboration, software quality, and delivery speed.

By the end of this guide, you’ll master best practices to take your BDD automation skills to the next level.

First, what exactly is BDD? And why does it warrant such attention on mastering automation?

What is BDD & Why Does it Matter?

BDD emerged in response to teams wanting better ways to describe software behavior and drive development based on those behaviors.

At its core, BDD aims to help teams:

Break down communication barriers between roles
Align software to business needs
Guide development & testing activities around desired behaviors

The result? Higher quality software matched to customer expectations – all through a shared understanding among the entire team.

And given today’s rapid delivery demands, BDD automation is now crucial for organizations to reap these benefits.

Consider these statistics that showcase why BDD & test automation must converge:

Software failure costs the US economy $1.7 trillion annually
Over 50% of time is spent on rework due to lacking requirements or miscommunications
Automated testing delivers 60 – 100x faster feedback than manual
75% higher customer satisfaction from teams using BDD techniques

The costs of defects and slower delivery are staggering. Automating BDD testing helps address this in a few key ways:

Facilitates collaboration: BDD standardizes the living requirements documentation that becomes automated scripts. This aligns the entire team around expected behaviors.

Enables continuous testing: Automated BDD tests integrate with CI/CD pipelines allowing constant validation of behaviors – no reliance on sporadic manual testing!

Sustainably scales test suites: The natural language framework makes BDD test code extremely maintainable compared to traditional code-based automation.

Now that you see the immense value prop here, let‘s get into the good stuff – how to actually achieve advanced test automation with BDD!

Best Practices for Advanced BDD Automation

Across my decade-plus in automated testing, I’ve distilled down key principles for maximizing BDD success:

1. Collaborate Constantly Between the "Three Amigos"

BDD brings together three critical perspectives through constant collaboration:

Business: Defines behaviors to solve problems
Developers: Implement behaviors
Testers: Confirm behaviors met

This collective understanding prunes misinterpretations upfront ensuring the system designed and built meets all needs!

Symptoms your collaborations need maturing? Ask yourself:

Is there confusion around expected behaviors?
Are discussions happening only within roles rather than cross-functionally?
Is development coding against unclear requirements?

If yes, instill rituals for the "three amigos" like:

Start sprints with behavior walkthrough sessions
Demo features against original specs in real-time
Celebrate examples of stellar collaboration

You’ll see enhanced trust, clarity, and efficiency.

2. Shift Testing Left Through Living Documentation

Want to amplify BDD benefits? Start automating scenarios early while closely collaborating with developers.

This shift left approach allows you to build an automated framework parallel to the app itself!

Benefits are immense:

Dev codes against clear specifications
Defects detected almost instantly rather than end system tests
Forever up-to-date requirements documentation

But many ask – how to drive this culture shift left? As the testing lead:

Actively participate in planning to translate stories into scenarios
Rapidly prototype automated framework while dev environment builds
Design seamless integrator workflows supporting constant test execution

You’ll transform into a proactive enabler of quality rather than reactive bottleneck!

3. Leverage Test Analytics for Greater Visibility

BDD tools provide stellar reporting but complement this by centrally analyzing test metrics. This unlocks a productivity goldmine!

For example, monitor:

Scenario pass rate trends
Step reuse frequency
Tests mapped to requirements
Failure incidence rates

Platforms like TestProject and Klov enable data flows into dashboarding tools. The quantitative insights supplement BDD’s living documentation.

You can precisely target weak spots like inconsistent tests, gauge test coverage, forecast quality risks – all using hard metrics! The analytics fuel data-backed decisions and process improvements.

4. Maximize Test Reuse Through Modularity

Now to my favorite way to accelerate BDD cycles – leverage reusable libraries for API testing, error validation, data setup.

See, BDD promotes readable keyword steps like:

When I enter valid credentials 
Then I should see homepage

But manually coding script logic behind every step is time-intensive.

The slick solution? Encapsulate common logic into modular code libraries that simply get invoked from there!

For example:

//CommonLibrary.java
login(String username, String password){
  //API call code  
}

//Steps.java 
@When("I enter valid credentials")
public void loginSteps(){
   CommonLibrary.login(user, pass); 
}

This makes steps implementation agnostic to testers. You also slash maintenance needs by isolation.

Set aside dedicated sprints to build these reusable assets. The payoff of amplified reuse is invaluable!

5. Verify Behaviors Across Environments

Here‘s a golden rule in test automation – always validate behaviors on real user environments.

With BDD, this means executing tests across diverse browsers, devices, and operating systems.

Why this cross-environment focus?

36% of web application defects are browser/device specific
A typical user base spans 6+ browser versions alone!

I recommend leveraging cloud labs like BrowserStack enabling automated test runs at massive scale. This catches environment induced defects instantly vs. playing catch up late in cycles.

See how aligning testing to real-world usage boosts customer satisfaction?

6. Shift Monitoring Left Too!

BDD principles apply not just during development but also in production monitoring.

How? Use executable specifications to continuously assess behavior of live apps!

For example, bake these validations into synthetic checks:

Scenario: Homepage load performance  
   Given user in US geography
    When user navigates to website 
   Then page load time should be under 2 secs

This allows you to instantly gauge whether site behavior matches expectations under real-user workloads.

Any deviations get flagged for investigation without customers ever facing problems!

You leverage BDD beyond development into making applications resilient. Talk about driving organizational maturity!

And that wraps up the key automation best practices I‘ve gathered from in-trenches software teams. Let‘s get you equipped to implement these high leverage solutions!
