Software Development Best Practice (minimum)
To track versions and manage an environment from deployment to recovery, source control is essential. Tracking changes, performing peer reviews before merging to the main master branch & the ability to rebuild/recover/revert to a previously known good state ensure quality throughout the process.
Example source control : GitHub
Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.
By integrating regularly, you can detect errors quickly, and locate them more easily.
Running new code through a pipeline of automated tests & peer review before reaching the test/uat environment ensures less regression errors & frustration for QA team.
Example CI : AppVeyor
Test Driven Development (TDD) involves coding test cases checking the newly implemented scenarios function as required (and ensure no regression when changes occur)
TDD is an essential tool in a programmers toolkit & is essential is required for modern dev positions.
