A presentation at PHPMinds - March 7th 2019 in March 2019 in Nottingham, UK by Antonios Pavlakis

Test automation and pipelines one step at a time Antonis Pavlakis @pavlakis

Code

Unit Tests (local environment) Possible steps required ● ● composer install bin/phpunit -c tests/phpunit/phpunit.xml

Unit Tests (CI environment) Possible steps required ● ● ● Download composer composer install bin/phpunit -c tests/phpunit/phpunit.xml

Bitbucket Pipelines

Pipeline status

Cache performance

Using a custom Docker image Dockerfile

Build Docker image docker build -t phpminds/php:7.2.15 . docker push phpminds/php:7.2.15

Pipeline with custom image

Pipeline performance

Integration Tests (local environment) Possible steps required ● ● ● ● composer install composer reset-db composer populate-db bin/phpunit -c tests/phpunit/phpunit.xml —group integration

Set DB to a known state “scripts”: { “reset-db”: [ “bin/console doctrine:database:drop —force”, “bin/console doctrine:database:create”, “bin/console doctrine:schema:update —force” Using composer scripts ], “populate-db”: [ “bin/console doctrine:fixtures:load” ] }

Docker Compose

Update Docker image Update Docker image ● Add mysql client

Run integration tests using Docker Compose If docker compose is not already running: docker-compose up —build -d Run tests from inside the running container: docker-compose exec -T phpminds-php sh -c “bin/phpunit -c tests/phpunit/phpunit.xml —group integration”

Docker Compose in Bitbucket Pipelines Steps required ● ● ● ● ● ● ● Install Docker Compose docker-compose up —build -d composer install (wait for DB container to start) composer reset-db composer populate-db bin/phpunit -c tests/phpunit/phpunit.xml —group integration

Install Docker Compose

Check DB connection

Putting it all together

A build with Docker Compose

Environment Variables

Using .env ci/assets/env.ci

Using .env

Managing secrets

Using repository variables

Acceptance Tests Possible steps required ● ● ● ● composer install composer reset-db composer populate-db bin/behat -c tests/behat/behat.yml

Example behat.yml

Add pipeline step

Where do you start from when it comes to test automation? In this talk we will start at the beginning. We will look at the steps for running tests locally and how we can automate them and run them using Bitbucket pipelines.
