Please read the full documentation at https://github.com/fschwaiger/matlab-dependency-injector.
This class automates the wiring of dependencies that are exposed in class constructors. It inspects the constructor argument names and finds appropriate dependencies via lookup files that you can define with each package. At any time, you can override dependencies, as shown in the example below.

% file +package/MyClass.m
classdef MyClass < handle
methods
function MyClass(firstDep, secondDep)
....
end
end
end

% file +package/InjectorConfig.m
classdef (Abstract, Hidden) InjectorConfig
properties (Constant)
firstDep = 'FirstDependencyClass'
end

methods (Static)
function value = secondDep()
value = 42;
end
end
end

% file application.m
instance = Injector().get(?package.MyClass);

% file unittest.m
firstDep = Mock(?package.FirstDependencyClass)
instance = Injector(firstDep).get(?package.MyClass);

Installation is really simple, you only need to copy a single file (Injector.m) to your project.

This class has been tested using newer versions of Matlab only (R2014b+), but it uses mostly standard tools that should be backwards compatible till R2009a. Please, if you find compatibility issues, notify me.
