double.js | A floating point expansion | Math library

Using the play.api.libs.json library, I am unable to create a Reads[T] object whenever only a single JsPath.read expression is used.

In the code below, I can read files only when the Reads[T] definition uses two or more JsPath.read expressions. Using only one, I get the following compiler errors:

• Premise: JS ES6, NodeJS
• Testing Framework: TAP
• Mocking Library: testdouble.js

I am attempting to mock the return value for the method of my class and keep receiving this error:

not ok Unsatisfied verification on test double. Wanted: - called with (true). But there were no invocations of the test double.

Here is my testing code:

I'm writing tests for a JS application using Jasmine and testdouble.js as a mocking library. I am using AMD format to organize code in modules, and RequreJS as a module loader. I was wondering how to use testdouble.js to replace dependency for the module being tested that is in AMD format and it is loading via RequireJS. The documentation is unclear about this or I am missing something, so if someone could point me in the right direction.

I'll post the example bellow that illustrates my setup and the problem that I am facing.
