[Verse 1]
Start with unit tests at the foundation floor
Fast and focused, checking each small door
Functions isolated, mocking what they need
Green checks flying at incredible speed
Thousands running while you grab your tea
Catching bugs before they multiply free
[Chorus]
Test pyramid climbing, unit at the base
Integration middle, end-to-end small space
Many at the bottom, fewer at the peak
Fast feedback cycles, confidence you seek
Pyramid climbing, balance is the key
Pyramid climbing, testing strategy
[Verse 2]
Integration layer where components meet
Database connections, APIs complete
Slower than units but faster than full
Testing contracts, making sure they pull
Together smoothly, interfaces align
Catching issues at the borderline
[Chorus]
Test pyramid climbing, unit at the base
Integration middle, end-to-end small space
Many at the bottom, fewer at the peak
Fast feedback cycles, confidence you seek
Pyramid climbing, balance is the key
Pyramid climbing, testing strategy
[Bridge]
Red, green, refactor when TDD makes sense
Complex algorithms, business logic dense
Write the test first, watch it fail with grace
Code the minimum to win the race
Clean it up while safety net stays tight
Three simple steps make everything right
[Verse 3]
End-to-end sparingly, just the critical flows
User journeys, how the whole thing goes
Expensive cameras filming every scene
Browser automation, slow but comprehensive
Few scenarios covering major ground
Confidence in what your users found
[Chorus]
Test pyramid climbing, unit at the base
Integration middle, end-to-end small space
Many at the bottom, fewer at the peak
Fast feedback cycles, confidence you seek
Pyramid climbing, balance is the key
Pyramid climbing, testing strategy
[Outro]
When to test-drive and when to test behind
Strategy matters more than tools you find
Pyramid wisdom, feedback velocity
Testing fundamentals, CTO mastery
