<div dir="ltr">Sounds good, I'll get started with tests for the demos and add tests for specific functions only as needed. I like the idea of 'integrated testing' using the demo files. It will also be a good opportunity to look closer at the demos to make sure each demo is comprehensive and serves a specific purpose.<div>

I would suggest starting with the demos, as this will test a broad set of functionality, and provides 'integration testing' for the entire package. It also minimizes test code to write at first.<br>
<br>
I agree that testing specific functions and inputs may be 'more robust', but it will also take (significantly) more time to design a test plan and suite of separate tests. I don't want to discourage that by any means, but I would want to get test coverage for the functionality in the demos first.<br>

With the optimization I've been doing in constrained_objective and now<br>
with the ROI changes, I am really starting to appreciate a more formal<br>
testing process instead of running demos and seeing what fails. I've<br>
started playing with the testthat package and really like it.<br>
<br>
I've had a look at quantstrat and plyr to see how the testthat package<br>
is used. The main difference is that quantstrat uses the demo files<br>
whereas plyr uses manually written test files. There are pros and cons<br>
to both approaches... using the demos as the tests minimizes duplicate<br>
code, but manual tests allow us to test specific things we may not<br>
need/want in the demos.<br>
<br>
I want to write some tests using testthat to include in<br>
PortfolioAnalytics, but would like your guidance on what framework or<br>
approach to use before I begin.<br>
