Jest TeamCity Reporter

jest-teamcity is a specialized Jest reporter designed to integrate test results with TeamCity CI/CD servers. Currently at version 1.12.0, this package provides detailed reporting, including test durations, pending test statuses, and full stack traces for failed tests, all formatted using TeamCity's service messages. It automatically groups tests into logical suites, enhancing readability and analysis within TeamCity's interface. Releases are generally infrequent, focusing on maintenance, dependency updates, and addressing specific edge cases or improvements in how Jest's internal APIs or TeamCity's expectations are handled. A key differentiator is its automatic activation based on the `TEAMCITY_VERSION` environment variable, ensuring it only outputs TeamCity-specific messages when running within that environment, while defaulting to standard Jest output otherwise. This prevents noisy output during local development.
