PHP & Selenium Parallel Tests

Options

1. Standard grid

• Pros: simple.
• Cons: All tests sequential.

2. Ant running groups in parallel (evenly split)

• Pros: easy to setup, does not effect current setup (provided Ant is used as build too), 2 result sets.
• Cons: tests in group run sequentially, as fast as slowest group.

3. Parallel tests (I. /brianium/paratest )

• Pros: runs all tests in parallel.
• Cons: results come back separately.

4. Parallel tests (II. /verkkokauppacom/parallel-phpunit)

• Pros: runs all tests in parallel.
• Cons: results come back separately.

Prerequisite

NB: From project root directory

1. Hub: java -jar selenium-server-standalone-2.32.0.jar -role hub
2. Slave(s): java -jar selenium-server-standalone-2.32.0.ja-role node -hub http://[HUB-IP]:4444/grid/register

Commands

1. phpunit --configuration phpunit-selenium.xml
2. ant -f build-selenium.xml
3. (did not work!) ../vendor/bin/paratest -p 2 -f --phpunit=/usr/bin/phpunit ApplicationTest/Selenium/
4. ./../vendor/bin/parallel-phpunit --pu-threads 2 -c phpunit-selenium.xml ApplicationTest/Selenium/

Results

NB: 2 tests with 2 assertions, 2 worker agents

1. 14s
2. 8s

Improvements

More tests should be created & run against a larger amount of selenium nodes
