Install following package as follows since 2.3.0 didn't came with allure-phpunit.

This issue is related with following issue

Fatal error: Class 'Codeception\Platform\Extension' not found. Issue occurred after magento 2.3.0 upgrade to 2.3.1

So in order for upgraded 2.3.0 to 2.3.1 magento to work install following.

composer require allure-framework/allure-phpunit:~1.2.0 --dev

Then run

bin/magento dev:tests:run unit
  • How come it doesn't come with Magento out of the box?

    While doing unit tests this was the error I was getting. I have updated the header. From investigation it appeared that magento 2.3.1 upgraded from 2.3.0 created compatibility issues for the allure-framework versions. Clean 2.3.1 comes with different allure-framework and upgraded 2.3.1 stays on the older version which has a different implementation.

  • Ah right interesting.. during the Magento 2.3.0 to 2.3.1 upgrade, did you diff composer.json files and bring over the new changes?

  • No I didn't I just followed the cli procedure recommended by magento for upgrades. [devdocs.magento.com/guides/v2.3/comp-mgr/cli/cli-upgrade.html]

  • Option --dev is default. It's not necessary to specify it. From documentation: --dev: Install packages listed in require-dev (this is the default behavior). Commented Feb 15, 2020 at 14:55
