Data QA Developer with Behavior-driven development (BDD) Salary in 2024

Where is Behavior-driven development (BDD) used?

Turning Specs into Red Carpet Events

• Transforms dull spec sheets into thrilling user stories. A-list stars are now features needing TLC!

Testing Tango

• BDD makes developers and testers dance together by coordinating test case choreography upfront. It's a match made in tech heaven!

Customer Whispering

• Ever tried to decipher what the client REALLY wants? BDD is like an interpreter for client-developer charades.

Team Mind-Meld

• It's like Vulcan mind-meld for teams: fosters shared understanding by having everyone speak Examples instead of Klingon.

Behavior-driven development (BDD) Alternatives

Test-Driven Development (TDD)

Test-Driven Development is a software development process where tests are written before the code itself. Developers write a test for a new function, run it (it should fail initially), write the code to make the test pass, and then refactor the code.

// Sample TDD Test Case
@Test
public void shouldReturnSumWhenTwoNumbersAreAdded() {
    Calculator calculator = new Calculator();
    assertEquals(5, calculator.add(2, 3));
}

• Encourages cleaner, more maintainable code


• Reduces the likelihood of bugs


• Improves design and API thought process


• Initial learning curve can be steep


• Requires discipline to maintain test-suite


• Test creation can be challenging for complex scenarios

Acceptance Test-Driven Development (ATDD)

ATDD involves team members with different perspectives (customer, development, testing) collaborating to write acceptance tests before coding. The focus here is on fulfilling all stakeholder expectations and requirements.

// Example Acceptance Test
Scenario: Account Holder withdraws cash
  Given the account balance is $100
  When the Account Holder requests $20
  Then the ATM should dispense $20
  And the account balance should be $80

• Fosters better collaboration across roles


• Focuses on user needs and requirements


• Can result in less rework


• May involve significant effort in aligning different perspectives


• Can be slow to get started as consensus is needed


• Acceptance criteria can become outdated quickly

Feature-Driven Development (FDD)

FDD is an agile framework that focuses on features. It emphasizes iterative and incremental development cycles, requiring domain models for feature lists and planning by feature.

// FDD Process Example
- Develop overall model
- Build feature list
- Plan by feature
- Design by feature
- Build by feature

• Promotes delivering tangible, working software repeatedly


• Helps track progress and results easily


• High-level view beneficial for clients and stakeholders


• Requires substantial up-front design and modeling


• Less known and used than other agile methodologies


• Potentially less adaptable to changes mid-project

Quick Facts about Behavior-driven development (BDD)

The Epic Tale of BDD's Birth

Picture it: the mid-2000s, a land brimming with clunky code and misunderstood requirements. Enter stage left: Dan North, a software wizard, who, in 2003, conjured up Behavior-driven development. Marrying the depths of Test-Driven Development with the heights of domain-driven design, he sought to end the developers' plight of miscommunication, making them chant, "Specs before code!"

A Cucumber Saga

Beneath the BDD kingdom, in 2008, lurked a beast named Cucumber, not your garden-variety veggie, but a tool that devoured "Gherkin" language for breakfast. It allowed mere mortals to pen down features as if they were telling a bedtime story, which Cucumber then magically turned into test scripts. This feature-frenzy sparked a revolution in how humans and code interacted in their quests for bug-free software.

The SpecFlow Chronicles

As the tale weaves on, lo and behold, the gallant SpecFlow galloped into the .NET realms in 2009. With its armor made of binding business-readable prose to living code, it declared, "I shall translate thine human wishes into tests!" A knightly addition to the BDD roundtable, ensuring no C#-coded citadel is ever misunderstood by its business seers again.

Given I am a gallant developer
When I write my tests in Gherkin
Then may my code be bug-free and clear as day!

   Gherkin Language

   
   

   
   Imagine you're writing a screenplay but for software - that's Gherkin for you! It's less about Hollywood drama and more about clear, human-readable descriptions for software behavior. Speak the language of "Given-When-Then" to outline scenarios for your app's functionality like you're storytelling to a toddler.

   Cucumber

   
   

   
   Ever thought veggies would help your code? Meet Cucumber, the tool that harnesses the power of Gherkin! It's like your personal BDD sous-chef, turning scenarios into automated tests across multiple languages. Cucumber dices through the jargon, ensuring everyone's on the same salad page.
   

   
   

   
         Feature: Is it Friday yet?
         Everybody wants to know when it's Friday
   
         Scenario: Sunday isn't Friday
           Given today is Sunday
           When I ask whether it's Friday yet
           Then I should be told "Nope"
