For the black box recorder we are using a specific configuration file called recorder-config.xml. For the test cases, we need an application that constructs all data structures from the recorder-config.xml. The pseudocode implementation would look like:

class App:
    
    def __init__(self):
        self.framedata
        self.logserver
        self.heartbeat
        ....
        self.plugins = [......]

or use any design by your liking. For reading xml you may want to learn a bit how to use python's xml module.

• You have to use xml module in python to parse the xml file.
• You have to design class-es for all tags in xml (ex. FrameData)

<FrameData
    header="32"
    channels="32"
    samplesPerChan="16"
/>

class FrameData:
    def __init__(self, ...):
        self.header
        self.channels
        self.samplesPerChan

• You have to use Facade pattern to group all in Application.py that will init all classes after parsing xml file.
• We have tag <Plugin> which can appear multiple times. We need every plugin to have the corresponing class and the App to hold an array or a dictionary, your choice of those, so we can easily traverse the plugins.
• Plugin must have a function put_data() that can store in Plugin class some data, string, array, int, whatever you design.

(Difficutly Level: 5) Extra credits will be given if a class PluginManager is created and can traverse to class Plugin. For this, you may want to implement a linked list
