see my solution how I messed up both my solution and the reference solution, and still was able to pass the kata

This is a problem with the Coffeescript translation, NOT with the user's solution. The reference solution depends on a function reverseSingleStrand which the user has to create to be able to build the tests, but this gives users autonomy over part of the expected results

point for you

I think that this is some issue specific to your solution since other people can pass both basic an random tests with the same code. You can paste your code here and mark it as spam so those that have already completed it can help you.

Output required by the instructions:

Frame 1: AGG TGA CAC CGC AAG CCT TAT ATT AGC
Frame 2: A GGT GAC ACC GCA AGC CTT ATA TTA GC
Frame 3: AG GTG ACA CCG CAA GCC TTA TAT TAG C

Reverse Frame 1: GCT AAT ATA AGG CTT GCG GTG TCA CCT
Reverse Frame 2: G CTA ATA TAA GGC TTG CGG TGT CAC CT
Reverse Frame 3: GC TAA TAT AAG GCT TGC GGT GTC ACC T

Output required by the basic test:

Frame 1: AGG TGA CAC CGC AAG CCT TAT ATT AGC
Frame 2: A GGT GAC ACC GCA AGC CTT ATA TTA GC
Frame 3: AG GTG ACA CCG CAA GCC TTA TAT TAG C

Reverse Frame 1: GCT AAT ATA AGG CTT GCG GTG TCA CCT
Reverse Frame 2: G CTA ATA TAA GGC TTG CGG TGT CAC CT
Reverse Frame 3: GC TAA TAT AAG GCT TGC GGT GTC ACC T

Output required by Random tests:

GCT TGT AAC AGA GAT TCC ATG CAG CGC,G CTT GTA ACA GAG ATT CCA TGC AGC GC,GC TTG TAA CAG AGA TTC CAT GCA GCG C

Reverse Frame 1: GCG CTG CAT GGA ATC TCT GTT ACA AGC
Reverse Frame 2: G CGC TGC ATG GAA TCT CTG TTA CAA GC
Reverse Frame 3: GC GCT GCA TGG AAT CTC TGT TAC AAG C

Note the first line of the outputs

Instructions: Frame 1: AGG TGA CAC CGC AAG CCT TAT ATT AGC

Basic test: Frame 1: AGG TGA CAC CGC AAG CCT TAT ATT AGC

Random tests: GCT TGT AAC AGA GAT TCC ATG CAG CGC ,G C CTT GTA ACA....

Obviously that makes it impossible to complete the kata.

please ellaborate

The only way to solve it is to evaluate if the input string matches the basic test and return the output in the format of that test, otherwise return in the manner expected by the random tests. But that solution implies bad practices.
The random tests do not respect the format of the output requested in the description of the Kata.

Well at leat one person has completed the kata on coffeescript so perhaps you are not asking the right questions

CoffeScript

language?

The basic test expect: 'Frame 1: AGG TGA ...' but the randoms test expets : 'AGA CGA GCT ..' and is imposible complete this kata.
