Json Parsing Tests - ExpandoObject or Json strings

Setting Up Jason Parsing Tests Using Dynamic Objects Or Strings

[Test]
public void SomeTestUsingExpandoObject()
{
  // arrange
  const string getItemEventDataValue = @"{
      ""_PrimaryId"": ""F:\\dasda\\ToMO-005775.json"",
      ""_SecondaryId"": ""123456"",
      ""RetrievalResult"": ""Processed Successfully""
    }";
  dynamic indexItemRaw = new ExpandoObject();
  indexItemRaw.id = sourceIndexItemId;
  indexItemRaw.version = sourceIndexItemVersion.ToString(CultureInfo.InvariantCulture);
  dynamic source = new ExpandoObject();
  source.getItemEventData = getItemEventDataValue;
  indexItemRaw.source = source;

  // act
  IEnumerable<ClaimDto> claimsEnum = someMapper.Map(JObject.FromObject(indexItemRaw));
  var claimDtos = claimsEnum.ToList();
  
  //assert
  ...
}

  //How to set up unit tests using strings to set up the data, instead of dynamic objects.
  //Sometimes it can be simpler, especially if you retrieve the raw data from a run
  //Here is the above test, arranged using a string as an example

Plant UML

Quite often I need to examine some existing code to find a solution to a problem. Sometimes this requires going in detail about what calls what and when. However, usually the code your looking at has many calls to many other objects. We don't want the details of every single call, just the important ones. Here sequence diagrams are very useful to document this visually. I prefer to use PlantUML for this because it allows you to write the diagram as text, PlantUml takes care of spacing everything appropriately. You can just get your object name/type and the method called on it from your IDE.
PlantUML is found at this web address: https://www.plantuml.com/ .
Here is some good documentation on how to use it: https://crashedmind.github.io/PlantUMLHitchhikersGuide/ .
Here is an example of using Plant UML to create a sequence diagram in UML:

@startuml actor Requestor as Actor participant MyApiController #9999ff 'note right of MyApiController 'All Api methods go through TryProcessRequest() 'end note Actor -/ MyApiController: Indexing note left: Normally this would be\ninitiated by a message\non the ServiceBus activate MyApiController MyApiController -> MyApiController: TryProcessRequest activate MyApiController note right: All Api methods go\nthrough TryProcessRequest() participant ServiceBus #99FF99 MyApiController -/ ServiceBus : PublishToTopic("topic.fromAlpha", IndexingCommand) deactivate MyApiController deactivate MyApiController ServiceBus -/ MyIndexingCommandHandler : HandleMessageAsync () activate MyIndexingCommandHandler  MyIndexingCommandHandler -> Indexer : RunIndexingJobAsync() activate Indexer note right: Number of retries of this method\nis controlled by SystemSetting\n"MyIndexingRetries", "FoobarService", 10\nIt is using the default value of 10!

Linqpad Notepad++ Hyperlink Extension

When searching through some files using LinqPad it can be useful to print out the results as a hyperlink that will open the file in Notepad++ at a particular line number.

public static class MyExtensions
{
    // Write custom extension methods here. They will be available to all queries.

    private const string notePadppPath = @"C:\Program Files\Tools\Notepad++\notepad++.exe";
    
    public static Hyperlinq CreateNotePadppHyperLink(this string filePath, int lineNumber)
    {
        var filelink = new Hyperlinq(() => Process.Start(notePadppPath, filePath + " -n" + lineNumber.ToString()), filePath);
        return filelink;
    }

}

Usage

string filePath = .... ;
filePath.CreateNotePadppHyperLink(lineNumber);
