2.使用shunit2做单元测试
test_config_line_paths() {
local s='partition cpm-all, 80-90,'
returns "/a" "config_line_paths '$s /a, '"
returns "/a /b/c" "config_line_paths '$s /a:/b/c, '"
returns "/a /b /c" "config_line_paths '$s /a : /b : /c, '"
}
config_line_paths() {
local partition_line="$@"
echo $partition_line
| csv_column 3
| delete_spaces
| column 1
| colons_to_spaces
}
source /usr/bin/shunit2
这里是另一个使用df命令的例子：
DF=df
mock_df_with_eols() {
cat <<- EOF
Filesystem 1K-blocks Used Available Use% Mounted on
/very/long/device/path
124628916 23063572 100299192 19% /
EOF
}
test_disk_size() {
returns 1000 "disk_size /dev/sda1"
DF=mock_df_with_eols
returns 124628916 "disk_size /very/long/device/path"
}
df_column() {
local disk_device=$1
local column=$2
$DF $disk_device
| grep -v 'Use%'
| tr 'n' ' '
| awk "{print $$column}"
}
disk_size() {
local disk_device=$1
df_column $disk_device 2
}
这里我有个例外，为了测试，我在全局域中声明了DF为非只读。这是因为shunit2不允许改变全局域函数。
