Oh - I thought it was another test case that failed and doesn't showing me the inputs. Now I see, thanks!

I'll try to explain for the 1st failing test if you read things correctly which is not evident.
All you need is displayed. You have:

Testing:
02|15|59, 2|47|16, 02|17|20, 2|32|34, 2|32|34, 2|17|17
My input is 02|15|59, 2|47|16, 02|17|20, 2|32|34, 2|32|34, 2|17|17
Actual: Range: 00|31|17 Average: 02|27|10 Median: 03|33|37
Expect: Range: 00|31|17 Average: 02|27|10 Median: 02|24|57
*
Test Failed
Expected "...: 02|27|10 Median: 0[2|24|5]7", but got "...: 02|27|10 Median: 0[3|33|3]7"

The last line says that you failed on "Median". You returned "03|33|37" written "0[3|33|3]7" to show the difference with expected median "02|24|57" written "0[2|24|5]7"
The "[" and "]" show where are the differences, "[3|33|3]" being different of "[2|24|5]". Is it clearer?
