Testing Scripts: Verify Scripts Work

Test scripts. Verify they work. Find problems. Important.

Here's the thing: Testing finds problems. Test scripts. Always.

Manual Testing​

./script.sh test_arg
# Verify output

My take: Manual testing works. Use it.

Test Functions​

test_function() {
    local result=$(my_function "input")
    if [ "$result" = "expected" ]; then
        echo "PASS"
    else
        echo "FAIL"
    fi
}

My take: Test functions verify behavior. Use them.

Common Patterns​

Test Suite​

run_tests() {
    test_function1
    test_function2
}

Now that you understand testing, you can verify scripts. Or review Best Practices to reinforce.

Personal note: Testing seemed unnecessary at first. Then scripts broke. Now I test always. It prevents problems. Test scripts.
