Watch out for | n/a | Test result counting is per spec file per run: each spec file execution that is recorded to Cypress Cloud counts as one test result, regardless of how many individual test cases (it blocks) are inside. A spec file with 50 tests counts as 1 result, but running that file 10 times in CI (e.g., on 10 PRs) counts as 10 results. High-frequency CI pipelines burn through the 120,000/year allocation faster than expected |
