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 [[https://github.com/pahaz/bashtest|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>
|
