Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Debug output during automation tests

I am trying to debug the following unit test for a 2D TArray-based class (MatrixRmn).

Something is wrong with my maths in this particular method, however debugging using break points in Visual Studio is a lesson in frustration, due to how Watching values cannot use an operator, leading to a series of lines looking like: PreReduced.operator[](0).operator[](0)

I have tried logging values, however I cannot see anything in my logs when running the test in the editor! (Session Frontend -> Automation -> Start Tests).

 bool MatrixRmnSolve::RunTest(const FString& Parameters)
     MatrixRmn PreReduced = MatrixRmn(4, 3);
     MatrixRmn ExpectedReduced = MatrixRmn(4, 3);
     PreReduced[0][0] = 1;
     PreReduced[0][1] = 2;
     PreReduced[0][2] = -2;
     PreReduced[1][0] = 2;
     PreReduced[1][1] = 3;
     PreReduced[1][2] = 0;
     PreReduced[2][0] = -1;
     PreReduced[2][1] = -1;
     PreReduced[2][2] = -3;
     PreReduced[3][0] = -4;
     PreReduced[3][1] = -11;
     PreReduced[3][2] = 22;
     ExpectedReduced[0][0] = 1;
     ExpectedReduced[0][1] = 0;
     ExpectedReduced[0][2] = 0;
     ExpectedReduced[1][0] = 0;
     ExpectedReduced[1][1] = 1;
     ExpectedReduced[1][2] = 0;
     ExpectedReduced[2][0] = 0;
     ExpectedReduced[2][1] = 0;
     ExpectedReduced[2][2] = 1;
     ExpectedReduced[3][0] = -8;
     ExpectedReduced[3][1] = 1;
     ExpectedReduced[3][2] = -2;
     MatrixRmn TestReduced = MatrixRmn(PreReduced);
     UE_LOG(LogTemp, Log, TEXT("TestReduced value is BLAH")); //, FString(TestReduced)
     //UE_LOG(LogTemp, Log, TEXT("ExpectedReduced value is %s"), FString(ExpectedReduced));
     TestEqual("ConvertToRowEchelonForm", TestReduced, ExpectedReduced);
     return true;

Figured out, looking at the wrong log...

I should have been looking at Session Frontend -> Console, not Window->Developer Tools->Output Log.
