Mocks, Provider Sandboxes or Maintained Test Environments?
Choose an integration test setup by the behavior you need to exercise, the evidence behind it and the work required to keep it current.

Integration failures you can investigate and test.
Start with four guides to choosing a test setup, reproducing a failure, checking recovery and keeping provider behavior current. Each includes a checklist and a sample record.
Start here
Build a regression case you can keep trusting.
Choose the setup, reproduce the failure, exercise difficult sync paths and maintain the provider evidence.
How to Reproduce an Integration Failure in CI
Turn an integration incident into a repeatable test with a known starting state, supported provider conditions, application checks and explicit limits.
Read the guideHow to Test Pagination, Rate Limits and Interrupted Syncs
Build document-sync regression cases for continuation links, throttled requests and crash recovery, with explicit starting state and application checks.
Read the guideHow to Keep Integration Tests Trustworthy as Providers Change
Maintain integration tests with sourced provider behavior, reviewed corrections and checks for changes in configurations, request patterns and evidence.

When a provider change triggers the work.
Trace the effect of an API change and check a migration across customer configurations. These guides extend the testing method to a specific change.
What an API Change Can Break in Your Integration
Trace an API change to affected integration behavior, then turn that impact into a regression scenario with a known result.
Read the guideHow to Verify an API Migration Across Customer Configurations
Verify a scoped API migration with target-version checks for agreed workflows, configurations, and failure paths.
