scripts:check-script

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.

https://wiki.bash-hackers.org/howto/testing-your-scripts

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>

Then make test suits for stat.sh. We make a directory testsuit which contain test python files.

 
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.

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!
