MethodCallCounter

===

**Count invocations of an arbitraty method in Ruby** - `solution.rb` required on top of your host script expects the target method signature in an environment variable `COUNT_CALLS_TO`. Given `COUNT_CALLS_TO` has a correct method signature, the script will print the number of target method's invocations at the end of execution. 

Valid method signatures:

```

Math.sin

ActiveRecord::Base.connection

String#size

Foo.bar

Post#status

etc...

```

Example

---

Require on app load:

```

# spec_helper.rb

...

require_relative '../../solution.rb'

...

```

Execute a Ruby script with `COUNT_CALLS_TO` set to count invocations of `Hash#dup`

```

$ COUNT_CALLS_TO='Hash#dup' rspec spec/controllers

# some output

Hash#dup has been invoked 2768 times

```

To Do

---

* Exception handling

* Handle optional parameters more gracefully

* Add more tests
