Sample scenarios can be found at


[Back To Top]

A skillstester scenario is defined in Markdown.

This skilltester-parser will convert the Markdown in a machine usable Json Scenario.

A scenario file consists of multiple Sections. Each Section is specified as level h1.

  • h1. Scenario contains the tasks & extra information
  • h1. Actions contains the actions
  • h1. Checks contains the checks
  • h1. Hardware contains the hardware
  • h1. Settings contains the settings

Linking elements inside a scenario

To reference an element inside the scenario you can use the following syntax -> @<special-type>: [a description](#<reference-to-special-definition>)

Known special-types are:

  • action: this will contain a block that will execute something
  • check: a check that will be executed
  • setting: a setting that can be loaded

A can contain any characters. But if you avoid spaces or '.', github will create autolink to your subsection elements.


-> @check: [A simple check](#simple-check-element)
-> @action: [A simple check](#simple-action-element)

Defining a special element

A h2. level element will define the id of the element you can refer to

Any list-item element of the form key: value will result in parameter


if you specify a @codeblock inside a value, if will load the next code element as a parameter

Parametrized content/elements

In values or text blocks, you can use the [mustache] syntax {{{ }}}.

Any settings you define in your settings block can be referenced with prefix:

  • scenario..

Other available prefixes are:

  • player.
  • hardware.<id>.ip_address

Solution block

Any action defined in a h3. block Solution will only be executed on request or in test-mode.

Json format

  actions: [],
  checks: [],
  hardware: [],
  scenario: []
