CI : the first_step: Auto Testing with CircleCI - (MOSG)

Continuous Integration - The first step of Auto Testing-

Continuous IntegrationIn software engineering, continuous integration (CI) is the practice of merging all developer working copies to a shared mainline several times a day.

Grady Booch first named and proposed CI in his 1991 method,[1] although he did not advocate integrating several times a day.

Extreme programming (XP) adopted the concept of CI and did advocate integrating more than once per day - perhaps as many as tens of times per day.

Almost development works are

‘Enhancement of current system’.

Why CI?

* Rapid cycle : ‘Plan(Enlarge) - Dev - Measure(Enlarge)’

* Tests : not only for new code, but also ALL. (to avoid regression)



Why CI?



Tests are increasing || Dev cycle is going faster

No way out

Huh? Tests? That’s not my business.

Please ask testers.

No problem. We are testing our code in

standard dev-flow

So, “Testing” become a much important thing than you think.

Let’s start Auto-testing

Today’s GOAL

1. push code to github 2. (AUTO) Testing on Circle CI 3. (AUTO) E-mail reporting

very simple

Flow

That’s ALL

create repository on github.com

create sample code and unit test code

register to CircleCI

You can try auto-testing very easy !

preparation - git clone - install required modules w/ composer

sample code

$ ./vendor/bin/phpunit PHPUnit 4.8.26 by Sebastian Bergmann and contributors.

OK (6 tests, 6 assertions) $

test at local environment

register repository to CircleCI

1. Open CircleCI

https://circleci.com/

Note) Please open github.com with your account on another tab.

http://github.com


2. Request authorization to your github


3. Confirm authorization


4. Select account (or Organization)


5. Select repository


6. Start build and testing !!!!

environment

closing

This screenshot is on a case without any test code.

NO TEST

That’s ALL

Much easier than I thought

circle.ymlA configuration file for CircleCI

try to specify PHP version on CircleCI.

machine: php: version: 5.6.14

circle.yml

git add, commit, push

circle.ymlSome more example

machine: php: version: 5.6.14

dependencies: override: - composer install --prefer-source --no-interaction --dev

test: override: - echo “Thanks for spending your time"

circle.yml

https://circleci.com/docs/configuration/

You can deploy code to specified EC2 server and test on the server. (if u need)

Thank you

I am happy, If you become

motivated to test.
