DiffPaneModel could report pass/fail

[daveyostcom]

I'm using DiffPlex to show differences when a unit test fails. Thank you!

For such uses, a property like this would be convenient in DiffPaneModel:

bool HasDifferences { get; }

Workaround is to first check if the strings are equal and call diff only if they're not.

Interesting suggestion, would you be interested contributing?

[daveyostcom]

Sorry, can't.

Have same issue as @daveyostcom . That property would be amazing. @mmanela i can contribute if u wish :) Do you have any slack or other for this project?

[mmanela]

@michasacuer I don't have a slack but we can use this item to discuss if that works

[michasacuer]

Cool, if i will have questions i will post it here :)

Im allowd to use Linq?

[daveyostcom]

Erik Meijer when asked what features of C# aren't used enough, answered LINQ and async/await. That was a while ago. 😎

[mmanela]

Linq is great!

DiffPlex is a great way to show test failures! While we're on the subject of diffing actual vs expected in test results,

Whereas +/–/␠ and green/red/grey work well to show new/old/same versions, when they are used to indicate actual vs expected test results, they are not so successful because they incur a cognitive load. Quick:

• Do +/– mean good/bad?
• Do +/– mean actual/expected or expected/actual?
• Should I think of actual/expected as old/new or new/old?
• Red goes with – and green goes with +; does red mean bad and green mean good?

  
  0 0.0

• 1 1.0
• 1 0.1 2 2.0
• 3 3.0 4 4.0 5 4.1
• 6 4.2

  
  Instead of + and –, it occurred to me to use

• √ and green for expected (good, but missing in the actual result)
• x and red for actual (bad, added or changed in the actual result)

I think this solution removes the cognitive load nicely.

  0 0.0
√ 1 1.0
x 1 0.1
  2 2.0
√ 3 3.0
  4 4.0
  5 4.1
x 6 4.2

I couldn't find a better Unicode checkmark that works reliably in monospaced fonts.
