Full Stack

Simple enough, but usable enough.

I have been using TestCaseLab for a year. It is great for writing test cases, executing tests and measuring test results.

An open-source & self-hostable Heroku / Netlify alternative that can be used to host and manage services, websites, databases, and custom applications.

Drupal is an open source platform for building amazing digital experiences.

For a CI system it is considered as "easy" and also well suited for .NET development.

I found this testing library very useful in communicating the business rules of our product. It takes a little bit of effort to get used to using the Gherkin language however. Though the test reports are clean and readable.

Some of the many features include an Analytics Web API, and a Tracking Web API.

Read positive things about it, but did not try it myself.
