At Instabug, they build an SDK for mobile apps and have developed a bespoke continuous integration workflow using CircleCI. Their workflow consists of four jobs: installing gems, running unit tests, generating a binary, and releasing the SDK. The first two jobs run in parallel and check for code quality, while the last two jobs are sequential and involve generating a binary and releasing the SDK. Instabug has automated their release process using CircleCI 2.0, which allows them to ship with confidence and save time by releasing once a week.
