Scope of assertions

Units tests only verify the correctness of the code under test

Integration style tests that verify correctness of code, API response, inter service contracts, queue messages and database queries

Quality of assertions

Hand written assertions might cover or miss logical correctness

Programmatic assertions that are deeper and wider and cover every corner case

Realism of test scenarios

Build and test scenarios that devs believe they know

Builds test from real-world scenarios and covers application faster than hand written tests

PACT style contract tests

Manual effort writing contract tests and updating if contract change

Automatically generate contract tests and update if they change. Manual effort eliminated.

Quality of contract Tests

PACT style contract tests will catch change in schema but will miss change in data value

HyperTest generated contract tests will catch schema changes as well as change in data value

Collaboration

If producer changes the contract for the consumer, it needs to update the PACT file for the consumer fails in production

If producer updates the contract, consumer is immediately notified before producer merges to production

Resilience to Changes

Tests may become outdated and less effective as external services change without corresponding updates to test cases.

Tests remain relevant and effective over time as Hypertest adapts to changes in external services.

Test Maintenance

Requires ongoing maintenance of tests to keep pace with changes.

No maintenance. Tests and mocks are auto-generated and auto-refreshed.

Scope of testing

Limited to testing internal logic and behavior of code units. Will miss integration failures like breaking contracts b/w services

Covers integration scenarios
