how to get only fully matched string from match

I need to match "test" or "test," from a string like 

"test, testhellowowo, wowtest,"

Attempt 1 

test[,]?

it will match all three since all of the string include the test regardless what comes after.

Attempt 2 

^test[,]?$

it won't match any unless the string is test or test,

Expected results

"test, testhellowowo, wowtest,".match(x) // should match `test,` 
"testhellowowo, wowtest,".match(x)  // should not match anything

If you need to include the punctuation mark you could also do /^test[,]?$/gm

^ matches beginning of string $ matches end of string

You can use word boundaries

/\btest\b/g

They match at

  • Before the first character in the string, if the first character is a word character.
  • After the last character in the string, if the last character is a word character.
  • Between two characters in the string, where one is a word character and the other is not a word character.
