Add endpoint, where telemetry request will be processed and stored to the file

[ms-iankudinova]

I want to be able to integrate 1DS Test Server to our pipeline with integration tests.

As a validation step, I want to check that:

• data was received in expected format
• all the expected fields were filled with expected data
• there were no missing fields, that were expected to be present in the telemetry
• no unexpected fields were added to the telemetry (no sensitive information, for example)

As a solution, I decided to store processed and decoded request to the file (json file), that can be read later by our integration test(s) and make this validation.

Name of the file can be configurable, by setting parameter FileNameToStoreTelemetryData to the appsettings.json. For example:

{
    "FileNameToStoreTelemetryData":"telemetry.json"    
}

Or during the run it can be override by passing environment variables.

If file name is not presented, 1DS test server will process the request and log it to the console, but will show the message, that data won't be stored to any file.

In our case, during one logic operation (flow) several telemetry requests are sent. I want to validate all of them. This is why this file will be updated every time, when new telemetry event during the operation will be received.

Between different tests 1DS Test Server can be restarted, and as a result file will be removed before Server will accept any new request. Also, if it is required to run tests in parallel, I believe, I can run it on different ports and pass different values of FileNameToStoreTelemetryData in environment variables

Looks good, but please check if in the solution you can still build the Fiddler inspector too.

This decoder code used in both - standalone server, as well as in Fiddler, so we need to make sure both still work.

[maxgolov]

My minor concern is we still need to make sure it works with Fiddler too. I honestly don't remember why we need this using, but if you can manually check that the Fiddler Inspector compiles Okay, that'd be great.

@maxgolov , I will check. By Fiddler Inspector do you mean project OneDSInspector?

[maxgolov]

Yup! Thank you so much. If we can't remove that, maybe we can use #if or something like that.

[ms-iankudinova]

I think it was added by actually: #1070

Looks good, agree with Max, we should check if it works with OneDInspector before merge.

@ms-iankudinova Do you plan to address the concerns raised here (validate building fiddler inspector), and then merge the PR ?

[ms-iankudinova]

Yes, will validate it and if it is ok - I will try to merge PR today
