Functional tests for examples #227
Description
Summary and context
Right now we have to manually check every example when new release or any change happens. Which is ... quite annoying and possibly error-prone. Therefore, it would be great to have an automated way how to do it and ideally also part of the Travis pipeline.
To keep our codebase "simple" we may use https://www.cypress.io/, since we are already using JavaScript.
What should be done:
- cover simple HTML examples
- cover channels example
- add missing simple HTML example to showcase how to do SSE/WS connection and subscription within the same HTTP call
- make it part of the Travis pipeline
Additionally, every new example should automatically include also test case for this.
