Testing your scripts
The one of the simplest way to check your bash/sh scripts is run it and check it output or run it and check the result. This tutorial shows how-to use bashtest tool for testing your scripts.
Write simple util¶
We have a simple stat.sh script:
#!/usr/bin/env bash
if [ -z "$1" ]
then
DIR=./
else
DIR=$1
fi
echo "Evaluate *.py statistics"
FILES=$(find $DIR -name '*.py' | wc -l)
LINES=$((find $DIR -name '*.py' -print0 | xargs -0 cat) | wc -l)
echo "PYTHON FILES: $FILES"
echo "PYTHON LINES: $LINES"
This script evaluate the number of python files and the number of python code lines in the files. We can use it like ./stat.sh <dir>
Create testsuit¶
Then make test suits for stat.sh. We make a directory testsuit which contain test python files.
testsuit/main.py
import foo
print(foo)
testsuit/foo.py
BAR = 1
BUZ = BAR + 2
Ok! Our test suit is ready! We have 2 python files which contains 4 lines of code.
Write bashtests¶
Lets write tests. We just write a shell command for testing our work.
Create file tests.bashtest:
$ ./stat.sh testsuit/
Evaluate *.py statistics
PYTHON FILES: 2
PYTHON LINES: 4
This is our test! This is simple. Try to run it.
# install bashtest if required!
$ pip install bashtest
# run tests
$ bashtest *.bashtest
1 items passed all tests:
1 tests in tests.bashtest
1 tests in 1 items.
1 passed and 0 failed.
Test passed.
Thats all. We wrote one test. You can write more tests if you want.
$ ls testsuit/
foo.py main.py
$ ./stat.sh testsuit/
Evaluate *.py statistics
PYTHON FILES: 2
PYTHON LINES: 4
And run tests again:
$ bashtest *.bashtest
1 items passed all tests:
2 tests in tests.bashtest
2 tests in 1 items.
2 passed and 0 failed.
Test passed.
You can find more .bashtest examples in the bashtest github repo. You can also write your question or report a bug here.
Happy testing!
