Tests

Introduction

We want to improve the code quality of Mirakel.

Unit Tests

• Models
• Helpers
• Sync

Functional Tests

• Interactive stuff
• Sync

How to achive 30% test coverage (Milestone 1)

• The progress must be visible
• Measuring code quality
• Measuring test coverage
• Every new function must have a test for it (Otherwise no +2)
• Every new feature must have a functional test for it (Otherwise no +2)
• Every non-hotfix must have tests for the fixed
  • A hotfix is:
    • Many users are affected
    • It's a critical crash
    • Absolute sync failures
• Every commit must improve the code quality
• No dirty hacks if there is an alternative

Unit Tests

1. Models
2. Sync
3. Helpers
4. Loose functions

Models

Tests for getter/setters in ..Base

We should write a script which generates the test code. Basically we want to test the following:

let a
F.setA(a)
F.getA() == a

Tests for non-getters/setters in ..Base

Database transactions

For every test class we need a clean demo database!

If possible we should write scripts for that

Insert

• count +1
• All old datasets exists
• a → insert → get → == a (except id)

Update

• count ==
• all ids exist
• a → update → get → == a (repeat this x times)
• no changes where there shouldn't be

Update many

• as Update
• No wrong changes

Delete

• Only deleted what should be deleted
• Delete m:n stuff

Getter

Here we should be very careful!

• Test vis a vis with hand written select
• Test different variations
• Test all possible parameter variations

CursorTo..

Here we should be very careful!

In doubt: rewrite constructors

Test table names in request <=> ALL_FIELDS array <=> Constructor param

toJSON

Handwritten item => handwritten JSON == generated JSON => check correctness

Do not forget to test all possible params

Sync

Input String → parse → toJSON == Input

Input string → parse == handwritten JSON

Using the tests of taskwarrior

We should test every feature independently + random combinations + all data + syntax errors + UDA

Helpers

Loose functions
