Search functional Web testing

I'm locking for a Software which allows me to test web Applications (HTML5, JavaScript, AngularJS).

The mayor Requirements are:

• It should have a GUI to maipulate the Recordings
• The langunge to create more Powerful tests should be Java or JavaSript
• And also my Customers often want to have a very detailed Testreport like: "Step 1: Action"; "Step 2: action" ...

I have looked into some of the OpenSource software but most of the time they do not meet the requirements and/or are not powerful enought.

I also did look into SmartBears "TestComplete" and MicroFokus "Silk" but both have difficulties with the reporting part.

Is there something I did not look into or can someone give me some advice where else to look or has a good alternative.

Thank you very much in advance.
