NOTICE

This decision has been migrated to the Technical Council's Decision Log as part of a consolidation effort.  See:  DR-000025 - Karate API Integration Tests Implementation Guidelines

 

Background

Some bugs can only be discovered by integrating modules together. It is challenging to identify these on an ongoing basis.

Some integration tests were already implemented. They use Postman collections. They are simple to write but harder to maintain.

It can be challenging to express more complex scenarios. Many of which were contributed by ThunderJet team.

ThunderJet teams has considered a range of tools and recommend Karate tool.

No alternative  proposals has been submitted  therefore Karate framework is preferred method for creating API integration tests in 2020.

API Integration Test Goal

  1. Automated regression

  2. Cross module interaction 

  3. Validate Producer/Consumer relationship

  4. Permissions

  5. No mock objects

Scope 

  1. Identify most important business flows

  2. Add test case to cover a bug condition

  3. Don't write tests for all possible conditions

Please note that the intent is not to replace rest assured/junit with karate but instead to get the benefits of both approaches

Create tests for new features

  1. Review if new feature has important business workflows and include test creation for these workflows into estimates

  2. Features are all ranked and it should determine if tests have to be created 

  3. SM need to drive NFR and make sure that Karate tests are scheduled into Sprints 

Test plan creation and estimation

  1. Before the end of R1 teams have to analyze existing API and identify important business flows  and created stubs for them.

  2. Create Jira tickets for implementation of this tests.

  3. Create an estimate for each Jira ticket

  4. Evaluate each workflow based on downstream dependencies

https://folio-org.atlassian.net/browse/FAT-146

Coverage calculation, reporting

  1. Coverage defined as % of implemented test cases to total test case count.

  2. Coverage will be calculated and reported by Jenkins pipeline

Test execution before and after PR

  1. Part of acceptance criteria - execute Katate tests before PR

  2. Deploy module in Scratch env. and run applicable tests

  3. Module changes and test changes are merged at the same time

  4. Test will be run automatically after PR in Jenkins pipeline the next day:

    1. https://jenkins-aws.indexdata.com/job/FOLIO_Reference_Builds/job/folio-api-tests-karate/

    2. https://jenkins-aws.indexdata.com/job/FOLIO_Reference_Builds/job/folio-api-tests-postman/

These pipelines are currently broken - https://folio-org.atlassian.net/browse/FOLIO-2982

Changes to DOD

  1. Every team should adjust DOD to require API Integration Tests 

Depreciation of Postman tests

  1. Mostly affects Spitfire and Thunderjet

  2. Continue to use Postman tests if team doesn't have desire to switch

  3. Passing tests are required  by acceptance criteria

  4. Postman test pipeline must be:

    1. operational 

    2. have no failures

  5. Defer decision when to deprecate these tests. 

How to evaluate for success

Proposed Action Items

Each team should change definition of done to make API integration tests required
All new BE features must include Karate tests. 
R1 Goal: Each team has to create a test plan for existing API interfaces
R1 Goal: Each team should provide estimates for the test plan. Estimates will be presented at the Capacity Planning meeting so that this work can be officially scheduled into sprints.
