About this tool
Test Pyramid Calculator
The Test Pyramid Calculator analyzes test composition ratios and total run time against ideal pyramid and testing trophy shapes.
• Identify whether a test suite is pyramid or ice cream cone shaped
• Calculate total test suite run time from test composition
• Assess whether E2E test overrepresentation is slowing CI
• Set test pyramid targets for a testing strategy document

FAQ
What does this tool tell you?
The Test Pyramid Calculator analyzes test composition ratios and total run time against ideal pyramid and testing trophy shapes.
What affects the result most?
Test pyramid: unit (fast/cheap) → integration → E2E (slow/expensive) — ideal ratio ~70/20/10. Ice cream cone anti-pattern: heavy E2E, light unit — slow, brittle, expensive to maintain. Unit test: tests one function/class in isolation — milliseconds, no I/O.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
