142 - 6 Ways to improve your code tests - How To Code Well | Lyssna här

Change log:

All the code notes for Docker for beginners course has been written. This is available on GitHub

I’ve started work on transcribing that course. This will take a long time.

I’ve fixed issues on howtocodewell.net regarding signup, forgotten password and other minor fixes

I’ve added the functionality to lock and unlock courses. This will turn them into private or public courses that require enrolment

6 ways to improve your testing

1) Automate as much as you can

Use CI pipelines

Run these locally even if your’e not committing any changes

Include other code auditing tools such as phpstan or phpmd

2) Statics are evil

There is no way to test a static method that calls another static method

3) Having many mocks is an indication of bad code design

4) Use tests to help refactor you code

If a unit of work cannot be easily tested then it usually means the code is not designed well

Break up your tests into smaller chunks

Tests can highlight micro and minor refactors

Refactor your code and then re test

Try and do this in a TDD fashion

5) Avoid flaky tests

Clean up state

Check for bottle necks which could cause timeouts

Mock external services or dependancies

Look into potential memory leaks

6) Re think what testing means to you

Testing is a contractual agreement between the programmer and the code

Testing is documentation - Gherkin, Acceptance Criteria, Business requirements

Testing is boundary setting which helps with focus

Testing is future proofing
