Swift Test Tear Down Inspection for AppCode

Motivation

For each test you write, an XCTestCase is allocated but never deallocated.

The best practice is to set all your instance variables to nil in the tear down method of your test.

This AppCode plugin inspects your tests and finds all places where one or more properties are not set to nil. It will also offer to fix the problem for you.

See the usages below on how to fix a single test file and how to apply the fix on all test files.

Installation

• Open AppCode
• Open AppCode → Preferences ⌘,
