Types of Assertions in Cypress

• Exploring Validation Techniques in Cypress Tests

2
Introduction to Assertions

• What are Assertions?Assertions validate expected
  outcomes during test execution. They ensure
  application behaviour matches requirements.
• Why Use Assertions in Cypress?
• Verify application states.
• Improve test reliability.
• Catch bugs effectively.
• Visual Flowchart showing testing with assertions.

3
Two Main Types of Assertions

• Implicit Assertions Automatically provided by
  Cypress commands (e.g., should).
• Explicit Assertions Require the use of assertion
  libraries like Chai.

4
Implicit Assertions

• Definition Built into Cypress commands, allowing
  direct chaining with keywords like. should ().
• Examples
• Existence Check should('exist')
• Visibility should ('be. Visible')
• Attribute Value should ('have.attr', 'href',
  '/home')
• Visual Example UI element with checkmarks for
  visibility, existence, etc.

5
Explicit Assertions

• Definition Require assertion methods like.
  expect () or. assert () for more custom
  validations.
• Examples
• expect(value).to. equal (10)
• assert. is True (true, 'Value is true')
• Usage Applied when complex logical checks are
  required.

6
Commonly Used Assertions

• State Assertions should ('be. checked'), should
  ('be. disabled').
• Text Assertions should('contain.text',
  'Welcome').
• URL Assertions should('include', '/dashboard').
• Length Assertions should ('have. Length', 5).
• Visual Table with Cypress commands and
  corresponding validations.

7
Benefits of Using Assertions

• Improved Accuracy Confirms test scenarios match
  expectations.
• Readable Tests Clearer intent in test scripts.
• Better Debugging Errors pinpoint failure points
  quickly.
• Visual Illustration of a magnifying glass over
  test steps.

8
Best Practices for Assertions

• Use Implicit Assertions for simplicity.
• Combine assertions with commands (e.g., click ().
  should ('be. Visible')).
• Keep assertions descriptive for better test
  readability.
• Avoid over-asserting focus on key elements only.

9
Summary

• Recap Assertions in Cypress ensure robust test
  validation.
• Key Takeaways
• Use implicit assertions for standard checks.
• Opt for explicit assertions for custom
  validations.
• Follow best practices to enhance test
  reliability.
• Visual Checklist graphic summarizing the key
  points.
