How to pass in Content-Type and base64 value as a user in Taurus?

Question

I'm trying to assign a user value which is base64 characters and the Content-Type which is "application/x-www-form-urlencoded". In my postman Content-Type is under Headers and user under body. Therefore i structured my yaml script like below :

execution:
  - concurrency: 10
    ramp-up: 20S
    hold-for: 1m
    scenario: sample

scenarios:
  sample:
    requests:
      - url: 'https://www.mtn.com/umbraco/surface/loginsurface/authenticate'
        method: POST
        headers:
          Accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp, application/x-www-form-urlencoded'
        Body:
          user: 'YWFkaWwuaaa2hhbkBzb3RpLdDpXZWxjb21lMTIzNA=='

However This isn't working when i'm running Taurus. Is the syntax wrong?

According to Taurus documentation

As you know, JSON is a subset of YAML

so Taurus supports both JSON and YAML configuration files
According to JSON specification

All names etc. are case-sensitive. Conforming implementations therefore MUST treat all names as being case-sensitive such the names "bar" and "BAR" would be seen as two distinct entities.
Looking further into Taurus documentation on YAML format:

Dictionaries are collections of key: value mappings. All keys are case-sensitive.

Therefore you just need to convert your Body to lowercase and everything should start working as expected (or at least result into following JMeter configuration)

Full YAML just in case:

execution:
  - concurrency: 10
    ramp-up: 20S
    hold-for: 1m
    scenario: sample

scenarios:
  sample:
    requests:
      - url: 'https://www.mtn.com/umbraco/surface/loginsurface/authenticate'
        method: POST
        headers:
          Accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp, application/x-www-form-urlencoded'
        body:
          user: YWFkaWwuaaa2hhbkBzb3RpLdDpXZWxjb21lMTIzNA==

You can always open JMeter GUI by running Taurus like:

bzt test.yaml -gui

or

bzt -o modules.jmeter.gui=true test.yaml

this way it will be easier to inspect the generated script.
