Set python test in jenkins

Regarding unit test

Preparation

Install unittest. (Python settings are omitted)

pip install unittest

Unittest example:

test.py

import unittest

class TestTagAprioriMain(unittest.TestCase):

    def setUp(self):
        print('start')

    def tearDown(self):
        print('finished')

    def test_success(self):
        res = 1 + 2
        self.assertEqual(res, 3)

    def test_success2(self):
        res = 1 + 2
        self.assertEqual(res, 3)

    def this_is_ignored(self):
        res = 1 + 2
        self.assertEqual(res, 1)

if __name__ == '__main__':
    unittest.main()

Execution result

start
finished
.start
finished
.
----------------------------------------------------------------------
Ran 2 tests in 0.000s

OK

The only point I want to suppress:

1. Methods starting with test_ are subject to testing. (In the above example, this_is_ignored is not called, it is ran 2 tests.)
2. setUp and tearDown are called before the test (test_ <..>) method, respectively. (It outputs start and finished to make it easier to understand when it is called)
3. This time, I used self.assertEqual () to check if the two are the same, but there are many others, so use the appropriate one.

How to test

Basic things:

self.assertEqual() 
self.assertTrue()
self.assertFalse()

Error checking

There is also an error test, and you can write the error pattern concretely by writing as follows. (The one on the official page below is posted as it is)

s = 'hello world'
self.assertEqual(s.split(), ['hello', 'world'])
with self.assertRaises(TypeError):
    s.split(2)

About jenkins

What is jenkins

https://jenkins.io/ jenkins is well known as a CI (Continuous Integration) tool. What is "continuous integration" just by looking at this? May be, but

Wikipedia：

• Mainly a habit for programmers to improve quality and shorten delivery time when creating applications. (.. Omitted ..) In a narrow sense, it means to continuously execute builds, tests, inspections, etc. *

http://e-words.jp/w/%E7%B6%99%E7%B6%9A%E7%9A%84%E3%82%A4%E3%83%B3%E3%83%86%E3%82%B0%E3%83%AC%E3%83%BC%E3%82%B7%E3%83%A7%E3%83%B3.html ：

• In software development, a method of finding problems early by repeating builds and tests frequently to improve development efficiency, save labor, and shorten delivery times. *

In other words, if you think about it simply, it's like ** continuously passing through tests **. (Because the author doesn't fully understand it)

The image is something like "automatically, you can check that the test has passed regularly".

Regarding the introduction of Jenkins

See other pages as we won't cover this time: https://appkitbox.com/knowledge/test/20121112-116

Make a new item

Set as Bitbucket has Repo

1. Set the git repo to bitbucket and register the SSH PubKey in Bitbucket as well.
2. Check Build when a change is pushed to BitBucket.

python version settings

If you don't have the pyenv build wrapper, install it on Jenkins

1. Select pyenv build wrapper in Build Environment and set 3.4.1 this time
2. Write the required Library in the preinstall pip list. Example: numpy, pyyaml, pandas

Set what works in the test

Write the necessary variable settings and commands to run in the execute shell of Build. (The following may be included, but ...)

PYENV_HOME=$WORKSPACE/.pyenv/
export PYTHONPATH=$WORKSPACE:"$(dirname "$WORKSPACE")"
python setup.py test

That's it. After that, save your changes, build and make sure it's a success.

If the test fails,

From the Job number, if you look at the Output Console, you can see the error just like a normal Terminal.
