[PHPUnit] Allowed memory size exhausted when tests with browsershot run

[michaelklopf]

I have a curious problem with Browsershot, when running my complete test suite on a Mac. The tests are running until I get a Allowed memory size of 1073741824 bytes exhausted error message. A single test is running successfully.

When re-running the test suite I had sometimes a Browsershot error. After removing the test cases where Browsershot is involved I had no problem and the test suite finished. We don't have the problem on the CI server. The test checks if a e-mail is send with a pdf generated by browser shot out of model data.

The error I got with the newest Browsershot version is this one:

There was 1 error:

I had a look through the puppeteer issues, as well as chromium but didn't find the right clue yet. Has anyone an idea how to fix this problem?

My guesses are

• problem with multiple tests that use browsershot and instances accessing each other?

Did you ever find a solution for this one? I'm also encountering this.

[michaelklopf]

I'm not perfectly sure how it went away. Either by updating to the newest version, or because we decreased memory consumption in the test runs with squashing migrations https://laravel.com/docs/10.x/migrations#squashing-migrations or using a fixed sql lite test database https://www.code-distortion.net/books/fast-test-databases/#chapter-4---use-a-pre-built-database

You setup (change db in .env to the sqlite file, run migrate command) a sql lite database in a file in your project and in phpunit.xml you can reference it

        <env name="DB_CONNECTION" value="sqlite"/>
        <env name="DB_DATABASE" value="./database/test_database.sqlite"/>

This slashed running 2000 tests to 30s on my M1 MBP, it was more than 10 minutes before that. (and having no memory problems doesn't trigger Browsershot errors if I'm right)
