Epic: API Unit/Integration Testing

[SakuraIsayeki]

Context:

Developing a new feature doesn't always yield on first try. There can be unexpected bugs/errors, within said feature, or any related feature (regressions).

Problem:

Currently, we need to test manually, or expose ourselves to runtime errors, during production.
How can we detect those bugs before deployment ?

Objective:

We need to predict broken features, with tests.

We must check our features prior to a new update/release. This should be done automatically.

Targets:

• Minimum code coverage of 80%, then raised to 90% at a later stage.
• Manual review from stakeholders, per new implemented features.

Conjectures:

Unit & Integration testing answers this issue, by trading off time for stability, and reducing the amount of bugs found in production/live ops.
This also has the additive side effect of making code more reusable, and pushing the developer towards Test Driven Development, which aids with clear feature implementations.
