CCCT-2687 Migrate Connect Network Stack To ConnectRepository - #3871
Conversation
📝 WalkthroughWalkthroughConnect operations moved from legacy callback-based API classes and Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This migration centralizes Connect network operations, but the current head can fail to initialize the network client, repeat navigation or error behavior after screen recreation, and miss delivery-completion or payment events. These issues can break Connect user flows, so the PR is not merge-ready until they are fixed. Sequence Diagram(s)sequenceDiagram

In `@app/src/org/commcare/connect/network/connect/ConnectNetworkClient.kt`:
- Around line 33-43: Update the BASE_URL constant used by ConnectNetworkClient
to include a trailing slash after BuildConfig.CCC_HOST, ensuring the value
passed to BaseApiClient.buildRetrofitClient is a valid Retrofit base URL.
In `@app/src/org/commcare/connect/repository/ConnectRepository.kt`:
- Around line 114-119: Move responseModel.applyToJob(job,
CommCareApplication.instance()) before the event predicates in the response
handling flow. Then evaluate getDeliveryProgressPercentage() and job.payments
after applying the response so newly completed deliveries and first payments
produce FINISH_DELIVERY and PAID_DELIVERY events, while preserving the existing
event reporting loop.
In `@app/src/org/commcare/connect/viewmodel/ConnectJobIntroViewModel.kt`:
- Around line 17-18: Replace retained terminal LiveData states with one-time
effect delivery for start-learning and claim operations. Update
ConnectJobIntroViewModel.kt lines 17-18 and ConnectLearningProgressViewModel.kt
lines 23-24, then consume each effect once in ConnectJobIntroFragment.kt lines
72-127 and ConnectLearningProgressFragment.java lines 144-170 so repeated
observation cannot retrigger navigation, launch, or error UI. Add Fragment
recreation or back-stack regression tests covering both flows.
In `@app/unit-tests/src/org/commcare/connect/network/ConnectMockApiServer.kt`:
- Around line 46-51: Update the mock server’s client lifecycle around start and
shutdown to call ConnectRepository.resetInstance() after injecting the new
ConnectNetworkClient and again after replacing it with null, ensuring
getInstance() rebuilds with the current client.
In `@app/unit-tests/src/org/commcare/connect/repository/ConnectRepositoryTest.kt`:
- Around line 52-53: Update the success-path tests in ConnectRepositoryTest to
use a payment fixture and explicitly verify that claims reach STATUS_DELIVERING
and ConnectJobUtils.upsertJob is invoked, while payments set confirmed and
ConnectJobUtils.storePayment is invoked. Remove or limit the broad stubs that
currently mask these side effects, and cover the relevant public methods in
ConnectRepository.
In
`@app/unit-tests/src/org/commcare/connect/viewmodel/ConnectJobIntroViewModelTest.kt`:
- Around line 57-59: Update the assertions in the affected
ConnectJobIntroViewModel tests to compare the complete terminal states directly:
expect DataState.Success(Unit) for successful results and
DataState.Error<Unit>() for error results, rather than checking only their
subtypes. Preserve the existing Loading assertion and result ordering.
In `@app/unit-tests/src/org/commcare/login/PostLoginSideEffectsTest.kt`:
- Around line 91-97: Update the runOnSuccess test around
mockRepository.syncJobProgress to return a flow builder that records when
collection starts, then assert that the collection marker is set after
PostLoginSideEffects.runOnSuccess completes. Replace the coVerify assertion,
which only verifies Flow creation, while preserving the existing analytics and
last-access assertions.

Calculate delivery events after applying the response.
job.getDeliveryProgressPercentage() and job.payments read the old job state before responseModel.applyToJob. A response that first reaches 100% delivery progress or adds the first payment does not report FINISH_DELIVERY or PAID_DELIVERY.
Apply the response before these predicates.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Verify Flow collection, not only Flow creation.
coVerify confirms that syncJobProgress(job) returns a Flow. It does not confirm that runOnSuccess collects the Flow. Use a flow { ... } test double that records collection, then assert that collection occurred.
As per coding guidelines, unit tests must “provide comprehensive coverage of all public methods in the tested class.”

…rningProgressViewModel Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Introduce getOpportunities, getLearningProgress, getDeliveryProgress, startLearning, claimJob, confirmPayments, and syncJobProgress on ConnectRepository, backed by the offline-first and network-only flow primitives. ConnectRepository is now the single network access point for all Connect features. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…JobHelper to ConnectRepository Replace every ConnectApiHandler inline usage and ConnectJobHelper network method with the equivalent ConnectRepository flow or callback. Callers in fragments and activities now go through ConnectRepository directly; ConnectJobHelper retains only its non-network helpers. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…login tests - ConnectLearningProgressFragmentTest: remove all spyk/mockk of ConnectRepository; seed user before activity creation so background getOpportunities call finds a user; pre-enqueue and drain getOpportunities and getLearningProgress responses so they don't pollute the claim request queue; all 7 tests pass against the real repository and ConnectMockApiServer - ConnectRepository: add @VisibleForTesting resetInstance() so tests can force a fresh singleton backed by the mock HTTP client - PostLoginSideEffects: make ConnectRepository injectable for unit testing - PostLoginSideEffectsTest: rewrite to use injected mock repository instead of mocking the singleton Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

To consider: There's almost nothing left in this class and I'm thinking it would make sense for the remaining methods to be merged into ConnectJobUtils. There are a couple static helper methods at the end of that class already, and two of the remaining three methods in this class lean pretty heavily on ConnectJobUtils anyway.
One downside to that though is that Helper is Kotlin and Utils is Java, so maybe better would be to prioritize converting Utils to Kotlin in a separate ticket and then merging the Helper functions over.

Product Description
Refactor introduces one minor UX change which is to show the loading bar on the Intro page when user clicks Download that triggers the start-learning API call -
Screen_recording_20260818_161128.mp4
I have tried otherwise to not introduce any other user visible changes on PR and keep the PR strictly as a code refactor.
Technical Summary
Replaces the scattered
ConnectApiHandler/ConnectJobHelper/ConnectApiClient/ApiConnectlayer withConnectRepositoryas the single network access point for all Connect features. All call sites in fragments, activities, workers, and login side effects are migrated; the old classes are deleted.Two ViewModel extractions accompany the migration:
ConnectJobIntroViewModel(previously inline in the fragment) and claim-job logic moved fromConnectJobClaimControllerintoConnectLearningProgressViewModel.Fragment and login tests were upgraded to use real HTTP mocks against
ConnectMockApiServerrather than mockingConnectRepositoryitself, so the full network path (including auth, parsing, and DB writes) is exercised in CI.Safety Assurance
