无法将第三个参数传递给 bash 脚本

Question

I think the answer will be pretty simple for you, however I cannot handle it alone. First of all function in the script looks like:

function assertEqual() {

    local expected=$1
    local actual=$2
    local message=$3

    echo $message

    if [ "$actual" = "$expected" ]
    then
        echo "Test OK (actual value: $actual)"
        return 0
    else
        echo "Test FAILED, EXPECTED VALUE: $expected, ACTUAL VALUE: $actual, WILL ABORT"
        return 1
    fi
}

The logic of the function do what it has to do, it is correct however I cannot find a way to print $message into console:

local message=$3
echo $message

I am invoking function like this:

assertEqual "$MOV_ID_REVS_RECS" $(echo $RESPONSE | jq .movieId) "Comparing id's"   
assertEqual 3 $(echo $RESPONSE | jq ".recommendations  | length") "Comparing recommendations length"    
assertEqual 3 $(echo $RESPONSE | jq ".reviews | length") "Comparing reviews length"

Output I get is like:

Test OK (HTTP Code: 200)
Test OK (HTTP Code: 200)
Test OK (HTTP Code: 200)
Wait for messages to be processed... 
Test OK (HTTP Code: 200)

Test OK (actual value: 2)

Test OK (actual value: 3)

Test FAILED, EXPECTED VALUE: 3, ACTUAL VALUE: 1, WILL ABORT

You can see that there are blank white rows which means that I am passing third argument wrongly right?

Answer 1

The issue may be multiple words in the substitution while passing the argument.

assertEqual "$MOV_ID_REVS_RECS" $(echo $RESPONSE | jq .movieId) "Comparing id's"   
assertEqual 3 $(echo $RESPONSE | jq ".recommendations  | length") "Comparing recommendations length"    
assertEqual 3 $(echo $RESPONSE | jq ".reviews | length") "Comparing reviews length"

Please try to quote the $(echo $RE...) > "$(echo $RE...)" in the arguments and test the results. Alternatively, try passing just assertEqual 3 test "Comparing reviews length" if all arguments work properly.
