Phpunit PR Coverage Check

Report Bug · Request Feature

About The Project

Inspired by https://github.com/richardregeer/phpunit-coverage-check

This project is a console command that filters the coverage report of your Phpunit tests to only take into account the modifications of a PullRequest, so you can be sure that the PR has enough tests.

Getting Started

Installation

Make sure Composer is installed globally, as explained in the installation chapter of the Composer documentation.

Open a command console, enter your project directory and execute:

$ composer require --dev orbeji/phpunit-pr-coverage-check

Usage

There are two ways of using this command:

• Passing a diff file
• Passing git repo information

With the first option you need to generate the appropiate diff file to pass to the command. The diff file must only contain the modified files/lines of the pr. To do that you can call git diff DESTINATION_BRANCH...PR_BRANCH > diff.txt with Bitbucket and GitHub you have environment variables to know the current and destination branches.

Diff file example: Bitbucket

vendor/bin/phpunit --configuration phpunit.xml.dist --testsuite pipelines --coverage-clover 'clover.xml'
git diff origin/${BITBUCKET_PR_DESTINATION_BRANCH}...origin/${BITBUCKET_BRANCH} > diff.txt
vendor/bin/pr-coverage-check check clover.xml 100 --diff=diff.txt --report=ansi

GitHub

vendor/bin/phpunit --coverage-clover clover.xml
git diff ${GITHUB_BASE_REF}...${GITHUB_REF_NAME} > diff.txt
vendor/bin/pr-coverage-check check clover.xml 100 --diff=diff.txt

Git repo information

vendor/bin/pr-coverage-check check clover.xml 100 --pullrequest-id=1 --provider=Github --workspace=orbeji --repository=test --api_token=API_TOKEN 

The API token must have permissions to the PullRequest scope.

For GitHub in the workspace option put the owner of the repo.

In any case if the coverage is not met the command will return the covered percentage

Coverage 40%

Reports

When executing the command line you can pass the option --report to generate a table with the uncovered lines of the PR

This option accepts 3 values:

• ansi: Coverage table in console output
• comment: Coverage table in PR comment
• report: Bitbucket report

Examples:

ansi:

root@bbfb2d246e64:/app# bin/pr-coverage-check check tests/clover.xml 90 --diff=tests/diff.txt --report=ansi
Coverage: 40%
--------------- ------------ 
File            Uncovered Lines
--------------- ------------ 
src/Dummy.php   19, 20, 26
