test1 <- as.matrix(c(1, 2, 3, 4, 5))
row.names(test1) <- c("a", "b", "c", "d", "e") 

test2 <- as.matrix(c(6, 7, 8, 9, 10))
row.names(test2) <- c("e", "d", "c", "b", "a") 

  test1
  [,1]
a    1
d    2
c    3
b    4
e    5

 test2
  [,1]
e    6
d    7
c    8
b    9
a   10

How can I reorder test2 so that the rows are in the same order as test1? e.g:

 test2
  [,1]
a    10
d    7
c    8
b    9
e    6

I tried to use the reorder function with: reorder (test1, test2) but I could not figure out the correct syntax. I see that reorder takes a vector, and I'm here using a matrix. My real data has one character vector and another as a data.frame. I figured that the data structure would not matter too much for this example above, I just need help with the syntax and can adapt it to my real problem.
