5-6: Approved: Improved clarity in example credentials.The changes to
POSTGRES_USERandPOSTGRES_PASSWORDimprove clarity and consistency with the.env.docker.examplefile. This is a good practice for maintaining uniform example configurations across different environment setups.Consider adding a comment above these lines to explicitly state that these are example values and should be changed in actual deployments. For example:
# postgres +# Note: Replace these example values with secure credentials in actual deployments POSTGRES_USER=postgres_user POSTGRES_PASSWORD=postgres_password.env.docker.example (1)
5-6: Security consideration: Descriptive credential names in example filesWhile using more descriptive names for credentials can improve clarity, it's worth noting that in example files, overly descriptive names might provide unnecessary information to potential attackers. Consider using generic placeholders instead, such as
YOUR_POSTGRES_USERandYOUR_POSTGRES_PASSWORD.Here's a suggested change:
-POSTGRES_USER=postgres_user -POSTGRES_PASSWORD=postgres_password +POSTGRES_USER=YOUR_POSTGRES_USER +POSTGRES_PASSWORD=YOUR_POSTGRES_PASSWORDThis approach maintains clarity while avoiding potential security concerns in example files.

30-32: Approve change fromafterEachtoafterAllwith a suggestionThis change aligns well with the
beforeAllmodification and can improve test suite performance by closing the NestJS application only once after all tests are complete.For added robustness, consider wrapping the
app.close()call in a try-catch block to ensure that any errors during teardown don't prevent other cleanup operations or cause the test suite to hang.Here's a suggested improvement:
afterAll(async () => { - await app.close(); + try { + await app.close(); + } catch (error) { + console.error('Error during app closure:', error); + } });apps/backend/e2e/tests/platform.e2e-spec.ts (3)

19-32: Approved: Lifecycle hook optimizationThe change from
beforeEachtobeforeAllis a good optimization that can significantly reduce the overall test execution time by initializing the application only once for all tests in this suite.However, be aware that this change might introduce shared state between tests. Ensure that:
- Individual tests don't modify global state that could affect other tests.
- If database operations are performed, consider implementing a cleanup mechanism or use transactions to isolate test data.
34-36: Approved: Consistent lifecycle hook changeThe change from
afterEachtoafterAllis consistent with the earlierbeforeAllmodification. This ensures that the application is closed only once after all tests in the suite have completed, which is more efficient.To further improve the robustness of the cleanup process, consider adding a try-catch block:
afterAll(async () => { try { await app.close(); } catch (error) { console.error('Error during app closure:', error); } });This will ensure that any errors during the closure process are logged and don't cause the entire test suite to fail unexpectedly.
Line range hint
19-36: Summary: Positive impact on test suite performanceThe changes to the lifecycle hooks (
beforeAllandafterAll) should significantly improve the performance of this test suite by reducing the number of times the application is initialized and torn down. This aligns well with the PR objective of improving CI for backend e2e tests.To further enhance the test suite:
- Consider adding a test for application startup and shutdown to ensure these processes work correctly, as they now happen only once per suite.
- If not already implemented, consider adding parallel test execution capabilities to take full advantage of the optimized setup.
- Monitor the execution time of this test suite in CI to quantify the performance improvement.

15-32: Optimize e2e test performance and suggest measurement.The changes to lifecycle hooks (
beforeAllandafterAll) should significantly improve the efficiency of this e2e test suite. This optimization aligns well with the PR objective of improving CI for backend e2e tests.To quantify the improvement, consider measuring and comparing the execution time before and after these changes. You can use the following script in your CI pipeline:
#!/bin/bash # Description: Measure and compare e2e test execution time # Run the tests and capture the execution time start_time=$(date +%s) npm run test:e2e -- apps/backend/e2e/tests/stop.e2e-spec.ts end_time=$(date +%s) # Calculate and print the execution time execution_time=$((end_time - start_time)) echo "E2E test execution time: $execution_time seconds" # Compare with previous runs (you'll need to implement a mechanism to store and retrieve previous times) # For example, you could store the time in a file and compare: # previous_time=$(cat previous_time.txt) # echo "Previous execution time: $previous_time seconds" # echo "Difference: $((previous_time - execution_time)) seconds" # Store the current time for future comparisons echo $execution_time > previous_time.txtThis script will help you track performance improvements over time and ensure that the changes are having the desired effect on CI efficiency.
15-15: Approve change tobeforeAll, but verify test independence.The change from
beforeEachtobeforeAllcan significantly improve test performance by reducing setup overhead. This is a good optimization for e2e tests.However, please ensure that all tests in this suite are independent and don't rely on a clean state for each test case. If any tests modify the application state, they should clean up after themselves.
To verify test independence, you can run the following script:
This script will help identify any database operations or state modifications within individual test cases, which might indicate potential issues with the
beforeAllapproach.apps/backend/e2e/tests/departure.e2e-spec.ts (2)
15-15: Approve change frombeforeEachtobeforeAllThis change improves the performance of the test suite by setting up the NestJS application only once for all tests, rather than before each individual test. This is particularly beneficial for end-to-end tests where application setup can be time-consuming.
Make sure that individual tests don't modify the application state in ways that could affect other tests. If they do, consider adding cleanup steps within the tests themselves.
Line range hint
15-32: Summary of changes and their impactThe modifications to this file, changing
beforeEachtobeforeAllandafterEachtoafterAll, are part of a broader optimization effort for e2e tests. These changes can significantly improve test execution time by reducing the number of times the NestJS application is set up and torn down.While this approach slightly reduces test isolation, it's generally an acceptable trade-off for e2e tests, especially when dealing with time-consuming operations like application setup.
To maintain test reliability:
- Ensure tests don't modify shared state in ways that affect other tests.
- If necessary, add test-specific setup or cleanup steps within individual test cases.
- Monitor the e2e test suite for any new flakiness or unexpected behaviors that might arise from these changes.
Overall, these changes should lead to faster and more efficient e2e testing without significantly compromising test quality.
