30.5 Validating results by output ¶

Function: dotest-output ¶

Function: dotest-output STRING ¶

Function: dotest-output STRING DESCRIPTION ¶

Read all the available lines from stdin accumulating them into a local variable, separated by \n; then compare the input with STRING, or the empty string if STRING is not present, and return true if they are equal, false otherwise.

The optional argument DESCRIPTION should be a short, one–line, string describing the expected value; it is used in the output text describing the failed comparison.

Example of test for a function that echoes its three parameters:

function my-lib-function () {
    echo $1 $2 $3
}
function mytest-1.1 () {
    my-lib-function a b c | dotest-output "a b c"
}
dotest mytest

Example of test for a function that is supposed to print nothing:

function my-lib-function () {
    test "$1" != "$2" && echo error
}
function mytest-1.1 () {
    my-lib-function a a | dotest-output
}
dotest mytest
