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:
<code> #!/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" </code>
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 <code> import foo print(foo) </code>
testsuit/foo.py <code> BAR = 1 BUZ = BAR + 2 </code>
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:
<code> $ ./stat.sh testsuit/ Evaluate *.py statistics PYTHON FILES: 2 PYTHON LINES: 4
</code>
This is our test! This is simple. Try to run it.
<code>
install bashtest if required!
$ pip install bashtest </code>
<code>
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. </code>
Thats all. We wrote one test. You can write more tests if you want.
<code> $ ls testsuit/ foo.py main.py
$ ./stat.sh testsuit/ Evaluate *.py statistics PYTHON FILES: 2 PYTHON LINES: 4
</code>
And run tests again:
<code> $ bashtest *.bashtest 1 items passed all tests: 2 tests in tests.bashtest 2 tests in 1 items. 2 passed and 0 failed. Test passed. </code>
You can find more .bashtest examples in the bashtest github repo. You can also write your question or report a bug here.
Happy testing!
