Continuous Integration (CI) är praxis där utvecklare regelbundet slår samman sin kod in i ett delat arkiv, där varje integration automatiskt verifieras (byggs och testas). Det fångar upp problem tidigt och håller kodbasen i ett hälsosamt, fungerande tillstånd.
Kärnpraxisen
Developers integrate code FREQUENTLY (at least daily) into the shared/main branch:
→ each integration is AUTOMATICALLY built and tested (by a CI server/pipeline)
→ problems are caught IMMEDIATELY (on each small change, not after weeks)
→ vs the old way: developers work in isolation for long periods → painful "integration
hell" when finally merging diverged work (many conflicts, surprises, bugs).
