Rules

@dazn/kopytko/dependencies-order

A rule to use with Kopytko Packager 's importing mechanism and Kopytko Unit Testing Framework 's mocking mechanism.

Enforces a proper alphabetical and path-specific order of @import and @mock annotations:

  1. imports or mocks from external packages have to be before local ones
  2. @mock annotations have to be after all @import annotations
  3. alphabetical order of external packages names
  4. alphabetical order of paths
  5. nested paths have to be declared after their root path

External packages before local

Example of incorrect code:

' @import /components/main-function.brs
' @import /components/nested/another-function.brs
' @import /components/nested/cool-function.brs
' @import /components/nested/some-function.brs from package-name
' @mock /components/mocked-function.brs
' @mock /components/some-mocked-function.brs from package-name

Example of correct code:

' @import /components/nested/some-function.brs from package-name
' @mock /components/some-mocked-function.brs from package-name
' @import /components/main-function.brs
' @import /components/nested/another-function.brs
' @import /components/nested/cool-function.brs
' @mock /components/mocked-function.brs

Imports before mocks

Example of incorrect code:

' @mock /components/mocked-function.brs
' @import /components/main-function.brs
' @import /components/nested/another-function.brs
' @import /components/nested/cool-function.brs

Example of correct code:

' @import /components/main-function.brs
' @import /components/nested/another-function.brs
' @import /components/nested/cool-function.brs
' @mock /components/mocked-function.brs

Alphabetical order of external packages names

Example of incorrect code:

' @import /components/a-function.brs from package-name
' @import /components/some-function.brs from another-package-name
' @mock /components/another-mocked-function.brs from package-name
' @mock /components/some-mocked-function.brs from another-package-name
' @import /components/main-function.brs
' @mock /components/mocked-function.brs

Example of correct code:

' @import /components/some-function.brs from another-package-name
' @import /components/a-function.brs from package-name
' @mock /components/some-mocked-function.brs from another-package-name
' @mock /components/another-mocked-function.brs from package-name
' @import /components/main-function.brs
' @mock /components/mocked-function.brs

Alphabetical order of paths

Example of incorrect code:

' @import /components/nested/another-function.brs
' @import /components/main-function.brs
' @import /components/nested/cool-function.brs
' @mock /components/some-mocked-function.brs
' @mock /components/mocked-function.brs

Example of correct code:
