Stop Sabotaging Your Tests: The Crucial Role of Naming Conventions

Without defined naming conventions, your automated tests can become a chaotic mess. Let’s consider a real-world example. Imagine you’re following a recipe to bake a cake. The recipe uses vague names for ingredients and steps, like this:

This makes it difficult to understand what each ingredient is and what you’re supposed to do. Now, let’s apply clear naming conventions:

Steps:

Now, imagine if the term “Ingredient A” was used inconsistently to mean both flour and sugar in different parts of the recipe. This inconsistency would lead to confusion and mistakes. Proper naming conventions prevent such issues by ensuring each term has a single, clear definition.

You might think it’s tedious to establish and follow these patterns, but the reality is, proper naming conventions are the backbone of a well-structured project, especially for automated tests.

Let’s consider examples of tests with and without defined naming conventions.

Without Naming Conventions

// registration.spec.js
describe('Registration', () => {
   it('Corresponds to mock-up registration page', () => {
      // complete mess of actions, all you probably like
   });   
   it('Verify user is registered', () => {
      // another "clear" check
   });
});

With Naming Conventions

// registration-page.ui.spec.js
describe('RegistrationPage', () => {
   before(() => {
      // navigation, preconditions
   });
   context('RegistrationPage.RegistrationForm: When user opens the Registration Form', () => {
      before(() => {
         // navigation, preconditions
      });
      it('RegistrationPage.RegistrationForm: Should display email field with placeholder and label', () => {
         // clear atomic check
      });      
      it('RegistrationPage.RegistrationForm: Should display password field with placeholder and label', () => {
         // clear atomic check
      });
   }); 
   context('RegistrationPage.RegistrationForm: When user fills Registration Form', () => {
      before(() => {
         // fill the form
      });
      it('RegistrationPage.RegistrationForm: Should display active Register button', () => {
         // clear atomic check
      });
   }); 
   context('RegistrationPage.RegistrationForm: When user clicks Register button', () => {
      before(() => {
         // click Register button
      });
      it('RegistrationPage.RegistrationForm: Should display Success Registration Notification', () => {
         // clear atomic check
      });
   });
});

The Harsh Truth

Let’s be blunt: if your automated tests lack consistent naming conventions, you’re setting yourself up for failure. Your test suite becomes a labyrinth of confusion, making it nearly impossible to navigate or maintain. This isn’t just about aesthetics; it’s about functionality and efficiency.

The Benefits You Can’t Ignore

  1. Well-structured Code: By defining naming conventions, you are pushed to structure the tests accordingly. All definitions, titles of instances, and names of files, methods, or tests can be aligned.
  2. Automation of Internal Checks and Scripts: With proper naming conventions, you can automate internal checks and scripts that manage your test suite. This means less manual intervention and more reliable processes.
  3. Smoother Onboarding: New team members can get up to speed faster without the need for extensive communication and documentation. Consistent naming conventions provide a clear roadmap, reducing the learning curve.
  4. Minimized Logical Mistakes: Consistent test names minimize the possibility of logical mistakes. When names are predictable and standardized, it’s easier to understand the test’s intent and catch errors early.
  5. Streamlined Communication: Clear naming conventions make each test more meaningful, making it easier to identify and correct errors. This is often aided by automation, which can quickly flag inconsistencies.
  6. Enhanced Maintainability: Proper naming conventions make your test suite more maintainable. You won’t need to spend hours deciphering what a test is supposed to do; the name tells you everything you need to know.
  7. Improved Metrics: With clear, consistent rules, your test metrics make sense. You can track performance, identify bottlenecks, and make informed decisions based on accurate data.
  8. Reduced Mental Load: With a solid naming convention, you don’t have to reinvent the wheel every time.

The Challenge

Are you ready to step up and implement proper naming conventions in your automated tests? Or will you continue to struggle with a disorganized test suite? The choice is yours, but remember, ignoring this crucial step is a recipe for disaster.

Conclusion

In conclusion, naming conventions are not just a nice-to-have; they are essential for the success of any automated testing project. They enable automation, streamline onboarding, minimize logical mistakes, and improve overall maintainability. Embrace proper naming conventions and watch your productivity soar.
