php-coveralls:tldr:283b1

The command php-coveralls is a command-line tool that helps with sending code coverage reports to the Coveralls service. In this particular command, it is being used to merge two separate Clover XML code coverage reports and send the merged report to Coveralls.

Here's a breakdown of the command:

• php-coveralls is the name of the command-line tool.
• --coverage_clover is an option that specifies the path to the Clover XML coverage report file.
• ${path-to-first_clover-xml} is the placeholder for the path to the first Clover XML coverage report file. You need to replace it with the actual path.
• ${path-to-second_clover-xml} is the placeholder for the path to the second Clover XML coverage report file. You need to replace it with the actual path.

Essentially, this command takes two separate Clover XML coverage report files, merges them together, and then sends the merged report to the Coveralls service. This can be useful when you have multiple test suites or multiple processes producing coverage reports, and you want to combine them into a single report for easier analysis and submission to Coveralls.
